The directors present the strategic report for the year ended 31 March 2025.

Carron Energy Limited is the parent company of an employee-owned Group that provides development and asset management services for flexible generation, storage and grid stability assets.

The Group’s principal source of revenue is its Management Services Agreements (MSAs). MSAs are signed with owners of power generation assets who outsource the operations of their assets to the Group. Carron Energy’s current portfolio of managed assets includes both operational assets and assets under construction. The Group also originates projects in the energy sector, supporting its long-term growth objectives.

The assets under management play a key role in the UK’s energy transition, providing flexible and dispatchable power generation to complement the growth of renewable forms of generation. The Group also manages stability assets which ensure the electricity system has adequate resilience to operate predominantly on low carbon forms of electricity generation.

At 31 March 2025, the Group has 47 projects (2024: 40) under management.

The Group’s revenue for the year was £7,811,000; an increase compared to the previous year revenue of £6,578,000. This growth was primarily driven by customer acquisition and expanded service scope for existing customers. Certain MSAs include performance-based components that are linked to the operational success and asset availability, which contributed to revenue resilience during the period.

The Group reported a loss of £567,000 for the financial year, compared to a profit of £7,400,000 in the previous year. The prior year’s performance benefited from disposal of subsidiaries, which included an element of deferred and contingent consideration. Following a reassessment of this consideration, the current year results were negatively impacted, an outcome that was in line with Directors’ expectations. Excluding the effect of this reassessment, the underlying business improved significantly, with EBITDA rising to £1,289,000 from £606,000 in the previous year.

The Directors remain confident in the robustness of the Group’s business model. Profitability is underpinned by the long-term nature of the Group’s contractual arrangements, which provide a stable foundation to the core business. Looking ahead, the Group remains focused on expanding its portfolio and maintaining operational excellence. The combination of long- term nature of the contracts and the diversified customer base position the Group well for future growth.

Financial and liquidity risk

The Group faces financial risk that could impact its performance, including the loss of key customers, unexpected costs and unforeseen events. The Group manages these risks by maintaining strong cash reserves and closely monitoring cash flow. Additionally, the Group has developed specific strategies to address its principal risks, as outlined below.

Operational and construction delays

Delays in the construction of new assets could impact the Group’s project timelines and financial performance. The Group mitigates this risk by employing robust project management practices, maintaining strong relationships with contractors and suppliers, and building flexibility into project schedules.

Regulatory and policy changes

Changes in energy regulations or government policies, particularly those relating to the energy transition and grid stability, could impact the Group’s operations. The Group actively monitors regulatory developments and adapts its business strategy to align with policy shifts, particularly those supporting the transition to a net-zero economy.

Customer retention and concentration risk

As with all customer focused businesses the loss of customers is a key risk particularly so given the Group’s relatively small number of primary customers. The Group actively works to mitigate this risk by focusing on strengthening its relationships with customers and ensuring high standards of service and performance.

Additionally, the long-term nature of the contracts the Group holds means that any impact from customer loss is likely to be gradual, providing time to implement effective mitigation strategies, such as cost reduction and pursuing new customers. However, the loss of key customers could still affect the Group’s future financial performance, making customer retention and acquisition a key continued focus for the business.

Credit risk

The Group is exposed to credit risk from customers operating in a volatile market environment. Market fluctuations, such as changes in energy prices or shifts in regulatory frameworks, can affect the financial stability of its customers. The Group actively manages this risk through initial credit assessments and monitoring the financial health throughout the duration of their contracts. Additionally, the diversification of the customer base works to reduce the potential impact of any single customer’s financial instability on the Group.

The financial and non-financial key performance indicators of the Group are as follows:

EBITDA has been calculated by adding depreciation and amortisation back to operating profit.

On behalf of the board

The directors present their annual report and financial statements for the year ended 31 March 2025.

The results for the year are set out on page 8.

The directors who held office during the year and up to the date of signature of the financial statements were as follows:

UHY Hacker Young have expressed their willingness to continue in office as auditor and appropriate arrangements have been put in place for them to be deemed reappointed as auditor in the absence of an Annual General Meeting.

So far as each person who was a director at the date of approving this report is aware, there is no relevant audit information of which the auditor of the company is unaware. Additionally, the directors individually have taken all the necessary steps that they ought to have taken as directors in order to make themselves aware of all relevant audit information and to establish that the auditor of the company is aware of that information.

This report has been prepared in accordance with the provisions applicable to companies entitled to the medium-sized companies exemption.

The directors are responsible for preparing the Annual Report and the financial statements in accordance with applicable law and regulations.

Company law requires the directors to prepare financial statements for each financial year. Under that law the directors have elected to prepare the financial statements in accordance with United Kingdom Generally Accepted Accounting Practice (United Kingdom Accounting Standards and applicable law). Under company law the directors must not approve the financial statements unless they are satisfied that they give a true and fair view of the state of affairs of the Group and company, and of the profit or loss of the group for that period. In preparing these financial statements, the directors are required to:

• select suitable accounting policies and then apply them consistently;

• make judgements and accounting estimates that are reasonable and prudent;

• state whether applicable UK Accounting Standards have been followed, subject to any material departures disclosed and explained in the financial statements;

• prepare the financial statements on the going concern basis unless it is inappropriate to presume that the group and company will continue in business.

The directors are responsible for keeping adequate accounting records that are sufficient to show and explain the group’s and company’s transactions and disclose with reasonable accuracy at any time the financial position of the Group and company and enable them to ensure that the financial statements comply with the Companies Act 2006. They are also responsible for safeguarding the assets of the Group and company and hence for taking reasonable steps for the prevention and detection of fraud and other irregularities.

We have audited the financial statements of Carron Energy Limited (the 'parent company') and its subsidiaries (the 'group') for the year ended 31 March 2025 which comprise the group profit and loss account, the group statement of comprehensive income, the group balance sheet, the company balance sheet, the group statement of changes in equity, the company statement of changes in equity, the group statement of cash flows and notes to the financial statements, including significant accounting policies. The financial reporting framework that has been applied in their preparation is applicable law and United Kingdom Accounting Standards, including Financial Reporting Standard 102 The Financial Reporting Standard applicable in the UK and Republic of Ireland (United Kingdom Generally Accepted Accounting Practice).

In our opinion the financial statements:

• give a true and fair view of the state of the group's and the parent company's affairs as at 31 March 2025 and of the group's loss for the year then ended;

• have been properly prepared in accordance with United Kingdom Generally Accepted Accounting Practice; and

• have been prepared in accordance with the requirements of the Companies Act 2006.

Basis for opinion

We conducted our audit in accordance with International Standards on Auditing (UK) (ISAs (UK)) and applicable law. Our responsibilities under those standards are further described in the Auditor's responsibilities for the audit of the financial statements section of our report. We are independent of the group and parent company in accordance with the ethical requirements that are relevant to our audit of the financial statements in the UK, including the FRC’s Ethical Standard, and we have fulfilled our other ethical responsibilities in accordance with these requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

Conclusions relating to going concern

In auditing the financial statements, we have concluded that the directors' use of the going concern basis of accounting in the preparation of the financial statements is appropriate.

Based on the work we have performed, we have not identified any material uncertainties relating to events or conditions that, individually or collectively, may cast significant doubt on the group's and parent company's ability to continue as a going concern for a period of at least twelve months from when the financial statements are authorised for issue.

Our responsibilities and the responsibilities of the directors with respect to going concern are described in the relevant sections of this report.

Other information

The other information comprises the information included in the annual report other than the financial statements and our auditor's report thereon. The directors are responsible for the other information contained within the annual report. Our opinion on the financial statements does not cover the other information and, except to the extent otherwise explicitly stated in our report, we do not express any form of assurance conclusion thereon. Our responsibility is to read the other information and, in doing so, consider whether the other information is materially inconsistent with the financial statements or our knowledge obtained in the course of the audit, or otherwise appears to be materially misstated. If we identify such material inconsistencies or apparent material misstatements, we are required to determine whether this gives rise to a material misstatement in the financial statements themselves. If, based on the work we have performed, we conclude that there is a material misstatement of this other information, we are required to report that fact.

We have nothing to report in this regard.

Opinions on other matters prescribed by the Companies Act 2006

In our opinion, based on the work undertaken in the course of our audit:

• The information given in the strategic report and the directors' report for the financial year for which the financial statements are prepared is consistent with the financial statements; and

• The strategic report and the directors' report have been prepared in accordance with applicable legal requirements.

In the light of the knowledge and understanding of the group and the parent company and their environment obtained in the course of the audit, we have not identified material misstatements in the strategic report or the directors' report.

We have nothing to report in respect of the following matters in relation to which the Companies Act 2006 requires us to report to you if, in our opinion:

• adequate accounting records have not been kept by the parent company, or returns adequate for our audit have not been received from branches not visited by us; or

• the parent company financial statements are not in agreement with the accounting records and returns; or

• certain disclosures of directors' remuneration specified by law are not made; or

• we have not received all the information and explanations we require for our audit.

As explained more fully in the directors' responsibilities statement, the directors are responsible for the preparation of the financial statements and for being satisfied that they give a true and fair view, and for such internal control as the directors determine is necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error. In preparing the financial statements, the directors are responsible for assessing the parent company's ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless the directors either intend to liquidate the parent company or to cease operations, or have no realistic alternative but to do so.

Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditor's report that includes our opinion. Reasonable assurance is a high level of assurance but is not a guarantee that an audit conducted in accordance with ISAs (UK) will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these financial statements.

Irregularities, including fraud, are instances of non-compliance with laws and regulations. We design procedures in line with our responsibilities, outlined below, to detect material misstatements in respect of irregularities, including fraud. The extent to which our procedures are capable of detecting irregularities, including fraud, is detailed below.

Our approach to identifying and assessing the risks of material misstatement in respect of irregularities, including fraud and non-compliance with laws and regulations, was as follows:

• the engagement partner ensured that the engagement team collectively had the appropriate competence, capabilities and skills to identify or recognise non-compliance with applicable laws and regulations;

• we identified the laws and regulations applicable to the group through discussions with directors and other management, and from our commercial knowledge and experience of the relevant sector;

• we focused on specific laws and regulations which we considered may have a direct material effect on the financial statements or the operations of the group, including the Companies Act 2006;

• we assessed the extent of compliance with the laws and regulations identified above through making enquiries of management and inspecting legal correspondence; and

• identified laws and regulations were communicated within the audit team regularly and the team remained alert to instances of non-compliance throughout the audit.

We assessed the susceptibility of the group's financial statements to material misstatement, including obtaining an understanding of how fraud might occur, by:

• making enquiries of management as to where they considered there was susceptibility to fraud, their knowledge of actual, suspected and alleged fraud; and

• considering the internal controls in place to mitigate risks of fraud and non-compliance with laws and regulations.

To address the risk of fraud through management bias and override of controls, we:

• performed analytical procedures to identify any unusual or unexpected relationships;

• tested journal entries to identify unusual transactions;

• assessed whether judgements and assumptions made in determining the accounting estimates were indicative of potential bias; and

• investigated the rationale behind significant or unusual transactions.

There are inherent limitations in our audit procedures described above. The more removed that laws and regulations are from financial statements, the less likely it is that we would become aware of non-compliance. Auditing standards also limit the audit procedures required to identify non-compliance with laws and regulations to enquiry of the directors and other management and the inspection of regulatory and legal correspondence, if any.

Material misstatements that arise due to fraud can be harder to detect than those that arise from error as they may involve deliberate concealment or collusion.

A further description of our responsibilities is available on the Financial Reporting Council’s website at: https://www.frc.org.uk/auditorsresponsibilities. This description forms part of our auditor's report.

Use of our report

This report is made solely to the company’s members, as a body, in accordance with Chapter 3 of Part 16 of the Companies Act 2006. Our audit work has been undertaken so that we might state to the company’s members those matters we are required to state to them in an auditor's report and for no other purpose. To the fullest extent permitted by law, we do not accept or assume responsibility to anyone other than the company and the company’s members as a body, for our audit work, for this report, or for the opinions we have formed.

These financial statements have been prepared in accordance with the provisions relating to medium-sized groups.

As permitted by s408 Companies Act 2006, the company has not presented its own profit and loss account and related notes. The company’s profit for the year was £3,988,000 (2024: £4,000,000).

These financial statements have been prepared in accordance with the provisions relating to medium-sized companies.

Carron Energy Limited (“the company”) is a private limited company domiciled and incorporated in England and Wales. The registered office is Fourth Floor, 2 Kingsway, Cardiff, CF10 3FD.

The group consists of Carron Energy Limited and all of its subsidiaries.

These financial statements have been prepared in accordance with FRS 102 “The Financial Reporting Standard applicable in the UK and Republic of Ireland” (“FRS 102”) and the requirements of the Companies Act 2006.

The financial statements are prepared in sterling, which is the functional currency of the company. Monetary amounts in these financial statements are rounded to the nearest thousand.

The financial statements have been prepared under the historical cost convention. The principal accounting policies adopted are set out below.

The company is a qualifying entity for the purposes of FRS 102, being a member of a group where the parent of that group prepares publicly available consolidated financial statements, including this company, which are intended to give a true and fair view of the assets, liabilities, financial position and profit or loss of the group. The company has therefore taken advantage of exemptions from the following disclosure requirements for parent company information presented within the consolidated financial statements:

• Section 7 ‘Statement of Cash Flows’: Presentation of a statement of cash flow and related notes and disclosures;

• Section 11 ‘Basic Financial Instruments’ and Section 12 ‘Other Financial Instrument Issues: Interest income/expense and net gains/losses for financial instruments not measured at fair value; basis of determining fair values; details of collateral, loan defaults or breaches, details of hedges, hedging fair value changes recognised in profit or loss and in other comprehensive income;

• Section 33 ‘Related Party Disclosures’: Compensation for key management personnel.

In the parent company financial statements, the cost of a business combination is the fair value at the acquisition date of the assets given, equity instruments issued and liabilities incurred or assumed, plus costs directly attributable to the business combination. The excess of the cost of a business combination over the fair value of the identifiable assets, liabilities and contingent liabilities acquired is recognised as goodwill. The cost of the combination includes the estimated amount of deferred and contingent consideration that is probable and can be measured reliably, and is adjusted for changes in deferred and contingent consideration after the acquisition date. Provisional fair values recognised for business combinations in previous periods are adjusted retrospectively for final fair values determined in the 12 months following the acquisition date. Investments in subsidiaries, joint ventures and associates are accounted for at cost less impairment.

Deferred tax is recognised on differences between the value of assets (other than goodwill) and liabilities recognised in a business combination accounted for using the purchase method and the amounts that can be deducted or assessed for tax, considering the manner in which the carrying amount of the asset or liability is expected to be recovered or settled. The deferred tax recognised is adjusted against goodwill or negative goodwill.

The consolidated group financial statements consist of the financial statements of the parent company Carron Energy Limited together with all entities controlled by the parent company (its subsidiaries) and the group’s share of its interests in joint ventures.

All financial statements are made up to 31 March 2025. Where necessary, adjustments are made to the financial statements of subsidiaries to bring the accounting policies used into line with those used by other members of the group.

All intra-group transactions, balances and unrealised gains on transactions between group companies are eliminated on consolidation. Unrealised losses are also eliminated unless the transaction provides evidence of an impairment of the asset transferred.

Subsidiaries are consolidated in the group’s financial statements from the date that control commences until the date that control ceases.

At the time of approving the financial statements, the directors have a reasonable expectation that the group has adequate resources to continue in operational existence for the foreseeable future. Thus the directors continue to adopt the going concern basis of accounting in preparing the financial statements.

Turnover is recognised at the fair value of the consideration received or receivable for goods and services provided in the normal course of business, and is shown net of VAT and other sales related taxes. The fair value of consideration takes into account trade discounts, settlement discounts and volume rebates.

When cash inflows are deferred and represent a financing arrangement, the fair value of the consideration is the present value of the future receipts. The difference between the fair value of the consideration and the nominal amount received is recognised as interest income.

Goodwill represents the excess of the cost of acquisition of a business over the fair value of net assets acquired. It is initially recognised as an asset at cost and is subsequently measured at cost less accumulated amortisation and accumulated impairment losses. Goodwill is considered to have a finite useful life and is amortised on a systematic basis over its expected life, which is 2 years.

For the purposes of impairment testing, goodwill is allocated to the cash-generating units expected to benefit from the acquisition. Cash-generating units to which goodwill has been allocated are tested for impairment at least annually, or more frequently when there is an indication that the unit may be impaired. If the recoverable amount of the cash-generating unit is less than the carrying amount of the unit, the impairment loss is allocated first to reduce the carrying amount of any goodwill allocated to the unit and then to the other assets of the unit pro-rata on the basis of the carrying amount of each asset in the unit.

Tangible fixed assets are initially measured at cost and subsequently measured at cost or valuation, net of depreciation and any impairment losses.

Depreciation is recognised so as to write off the cost or valuation of assets less their residual values over their useful lives on the following bases:

The gain or loss arising on the disposal of an asset is determined as the difference between the sale proceeds and the carrying value of the asset, and is recognised in the profit and loss account.

Equity investments are measured at fair value through profit or loss, except for those equity investments that are not publicly traded and whose fair value cannot otherwise be measured reliably, which are recognised at cost less impairment until a reliable measure of fair value becomes available.

In the parent company financial statements, investments in subsidiaries and jointly controlled entities are initially measured at cost and subsequently measured at cost less any accumulated impairment losses.

A subsidiary is an entity controlled by the group. Control is the power to govern the financial and operating policies of the entity so as to obtain benefits from its activities.

Entities in which the group has a long term interest and shares control under a contractual arrangement are classified as jointly controlled entities.

At each reporting period end date, the group reviews the carrying amounts of its tangible and intangible assets to determine whether there is any indication that those assets have suffered an impairment loss. If any such indication exists, the recoverable amount of the asset is estimated in order to determine the extent of the impairment loss (if any). Where it is not possible to estimate the recoverable amount of an individual asset, the company estimates the recoverable amount of the cash-generating unit to which the asset belongs.

The carrying amount of the investments accounted for using the equity method is tested for impairment as a single asset. Any goodwill included in the carrying amount of the investment is not tested separately for impairment.

Recoverable amount is the higher of fair value less costs to sell and value in use. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset for which the estimates of future cash flows have not been adjusted.

If the recoverable amount of an asset (or cash-generating unit) is estimated to be less than its carrying amount, the carrying amount of the asset (or cash-generating unit) is reduced to its recoverable amount. An impairment loss is recognised immediately in profit or loss, unless the relevant asset is carried at a revalued amount, in which case the impairment loss is treated as a revaluation decrease.

Recognised impairment losses are reversed if, and only if, the reasons for the impairment loss have ceased to apply. Where an impairment loss subsequently reverses, the carrying amount of the asset (or cash-generating unit) is increased to the revised estimate of its recoverable amount, but so that the increased carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognised for the asset (or cash-generating unit) in prior years. A reversal of an impairment loss is recognised immediately in profit or loss, unless the relevant asset is carried at a revalued amount, in which case the reversal of the impairment loss is treated as a revaluation increase.

The group and company have elected to apply the provisions of Section 11 ‘Basic Financial Instruments’ and Section 12 ‘Other Financial Instruments Issues’ of FRS 102 to all of its financial instruments.

Financial instruments are recognised in the group's balance sheet when the group becomes party to the contractual provisions of the instrument.

Financial assets and liabilities are offset and the net amounts presented in the financial statements when there is a legally enforceable right to set off the recognised amounts and there is an intention to settle on a net basis or to realise the asset and settle the liability simultaneously.

Basic financial assets, which include debtors and cash and bank balances, are initially measured at transaction price including transaction costs and are subsequently carried at amortised cost using the effective interest method unless the arrangement constitutes a financing transaction, where the transaction is measured at the present value of the future receipts discounted at a market rate of interest. Financial assets classified as receivable within one year are not amortised.

Other financial assets, including investments in equity instruments which are not subsidiaries, associates or joint ventures, are initially measured at fair value, which is normally the transaction price. Such assets are subsequently carried at fair value and the changes in fair value are recognised in profit or loss, except that investments in equity instruments that are not publicly traded and whose fair values cannot be measured reliably are measured at cost less impairment.

Project development costs, including those related to site identification, land acquisition, design, and obtaining consents, are deferred when it is probable that the resulting project will generate future economic benefits for the group at least equal to the costs incurred. Costs that are not expected to be recoverable are expensed in the period in which they are incurred, or when it becomes apparent that the project will not proceed.

Financial assets, other than those held at fair value through profit and loss, are assessed for indicators of impairment at each reporting end date.

Financial assets are impaired where there is objective evidence that, as a result of one or more events that occurred after the initial recognition of the financial asset, the estimated future cash flows have been affected. If an asset is impaired, the impairment loss is the difference between the carrying amount and the present value of the estimated cash flows discounted at the asset’s original effective interest rate. The impairment loss is recognised in profit or loss.

If there is a decrease in the impairment loss arising from an event occurring after the impairment was recognised, the impairment is reversed. The reversal is such that the current carrying amount does not exceed what the carrying amount would have been, had the impairment not previously been recognised. The impairment reversal is recognised in profit or loss.

Financial assets are derecognised only when the contractual rights to the cash flows from the asset expire or are settled, or when the group transfers the financial asset and substantially all the risks and rewards of ownership to another entity, or if some significant risks and rewards of ownership are retained but control of the asset has transferred to another party that is able to sell the asset in its entirety to an unrelated third party.

Financial liabilities and equity instruments are classified according to the substance of the contractual arrangements entered into. An equity instrument is any contract that evidences a residual interest in the assets of the group after deducting all of its liabilities.

Basic financial liabilities, including creditors, bank loans, loans from fellow group companies and preference shares that are classified as debt, are initially recognised at transaction price unless the arrangement constitutes a financing transaction, where the debt instrument is measured at the present value of the future payments discounted at a market rate of interest. Financial liabilities classified as payable within one year are not amortised.

Debt instruments are subsequently carried at amortised cost, using the effective interest rate method.

Trade creditors are obligations to pay for goods or services that have been acquired in the ordinary course of business from suppliers. Amounts payable are classified as current liabilities if payment is due within one year or less. If not, they are presented as non-current liabilities. Trade creditors are recognised initially at transaction price and subsequently measured at amortised cost using the effective interest method.

Financial liabilities are derecognised when the group's contractual obligations expire or are discharged or cancelled.

The tax expense represents the sum of the tax currently payable and deferred tax.

The tax currently payable is based on taxable profit for the year. Taxable profit differs from net profit as reported in the profit and loss account because it excludes items of income or expense that are taxable or deductible in other years and it further excludes items that are never taxable or deductible. The group’s liability for current tax is calculated using tax rates that have been enacted or substantively enacted by the reporting end date.

Deferred tax liabilities are generally recognised for all timing differences and deferred tax assets are recognised to the extent that it is probable that they will be recovered against the reversal of deferred tax liabilities or other future taxable profits. Such assets and liabilities are not recognised if the timing difference arises from goodwill or from the initial recognition of other assets and liabilities in a transaction that affects neither the tax profit nor the accounting profit.

The carrying amount of deferred tax assets is reviewed at each reporting end date and reduced to the extent that it is no longer probable that sufficient taxable profits will be available to allow all or part of the asset to be recovered. Deferred tax is calculated at the tax rates that are expected to apply in the period when the liability is settled or the asset is realised. Deferred tax is charged or credited in the profit and loss account, except when it relates to items charged or credited directly to equity, in which case the deferred tax is also dealt with in equity. Deferred tax assets and liabilities are offset if, and only if, there is a legally enforceable right to offset current tax assets and liabilities and the deferred tax assets and liabilities relate to taxes levied by the same tax authority.

The costs of short-term employee benefits are recognised as a liability and an expense, unless those costs are required to be recognised as part of the cost of stock or fixed assets.

The cost of any unused holiday entitlement is recognised in the period in which the employee’s services are received.

Termination benefits are recognised immediately as an expense when the company is demonstrably committed to terminate the employment of an employee or to provide termination benefits.

Payments to defined contribution retirement benefit schemes are charged as an expense as they fall due.

Equity-settled share-based payments are measured at fair value at the date of grant by reference to the fair value of the equity instruments granted using the Black-Scholes model. The fair value determined at the grant date is expensed on a straight-line basis over the vesting period, based on the estimate of shares that will eventually vest. A corresponding adjustment is made to equity.

The expense in relation to options over the parent company’s shares granted to employees of a subsidiary is recognised by the company as a capital contribution.

When the terms and conditions of equity-settled share-based payments at the time they were granted are subsequently modified, the fair value of the share-based payment under the original terms and conditions and under the modified terms and conditions are both determined at the date of the modification. Any excess of the modified fair value over the original fair value is recognised over the remaining vesting period in addition to the grant date fair value of the original share-based payment. The share-based payment expense is not adjusted if the modified fair value is less than the original fair value.

Cancellations or settlements (including those resulting from employee redundancies) are treated as an acceleration of vesting and the amount that would have been recognised over the remaining vesting period will be recognised immediately.

Rentals payable under operating leases, including any lease incentives received, are charged to profit or loss on a straight line basis over the term of the relevant lease except where another more systematic basis is more representative of the time pattern in which economic benefits from the leased asset are consumed.

Transactions in currencies other than pounds sterling are recorded at the rates of exchange prevailing at the dates of the transactions. At each reporting end date, monetary assets and liabilities that are denominated in foreign currencies are retranslated at the rates prevailing on the reporting end date. Gains and losses arising on translation in the period are included in profit or loss.

In the application of the group’s accounting policies, the directors are required to make judgements, estimates and assumptions about the carrying amount of assets and liabilities that are not readily apparent from other sources. The estimates and associated assumptions are based on historical experience and other factors that are considered to be relevant. Actual results may differ from these estimates.

The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognised in the period in which the estimate is revised where the revision affects only that period, or in the period of the revision and future periods where the revision affects both current and future periods.

The estimates and assumptions which have a significant risk of causing a material adjustment to the carrying amount of assets and liabilities are as follows.

Other debtors at 31 March 2025 includes £1,799,000 (2024: £6,600,000) of deferred and contingent consideration relating to the sale of subsidiaries. The amount recognised at the balance sheet date is based on the board's best estimate of the consideration receivable based on milestones in the sale and purchase agreements. The board reviews deferred and contingent consideration at each balance sheet date to review likely recoverability taking into consideration relevant factors which require estimation and judgement.

The carrying value of the company's investment in its subsidiary, Welsh Power Group Limited ("Welsh Power") is £15,723,000 (2024: £15,723,000). The board undertakes an impairment review at each balance sheet date to consider whether the value of its investment requires adjustment. The directors believe that the carrying value of the company's investment in Welsh Power has not been reduced; this is an area of judgement and includes an evaluation of the future profitability of Welsh Power.

At 31 March 2025 the Group has deferred development costs of £1,120,000 (2024: £321,000) relating to site identification, land acquisition, design, and consents on projects. Costs are deferred where it is probable that future economic benefits will flow to the Group at least equivalent to the costs incurred. Management applies judgement in determining whether development costs meet the criteria for deferral. Costs are capitalised only when it is probable that future economic benefits will exceed the costs incurred. This involves assessing project viability, expected returns, and recoverability. Deferred costs are reviewed regularly and written off if the project is no longer expected to proceed.

All turnover relates to the group's principal activities as laid out in the Directors' report.

All turnover arose in the UK.

The average monthly number of persons (including directors) employed by the group and company during the year was:

Their aggregate remuneration comprised:

The number of directors for whom retirement benefits are accruing under defined contribution schemes amounted to 5 (2024 - 5).

The actual charge for the year can be reconciled to the expected (credit)/charge for the year based on the profit or loss and the standard rate of tax as follows:

The group has unused tax losses carried forward of £8,575,000 (2024: £8,602,000). More information is provided in note 18.

The goodwill arose as a result of Welsh Power Group Limited (a subsidiary of Carron Energy Limited) acquiring a 51% shareholding in Northern Grid Services Limited and Western Grid Services Limited during the year ending 31 March 2024.

Details of the company's subsidiaries at 31 March 2025 are as follows:

Registered office addresses (all UK unless otherwise indicated):

During the prior year WP Grid Services Limited (a subsidiary of Carron Energy Limited) sold its shareholding in its subsidiaries, Sellindge Grid Services Limited and Cilfynydd Grid Services Limited.

Other debtors includes £1,799,000 (2024: £6,644,000) in relation to deferred consideration on the sale of subsidiaries.

The following are the major deferred tax liabilities and assets recognised by the group and company, and movements thereon:

The deferred tax liability set out above relates to accelerated capital allowances that are expected to mature within the same period, these are offset fully by the deferred tax asset relating to retirement benefit obligations.

The Group has not recognised a deferred tax asset on unused tax losses carried forward of £8,575,000 (2024: £8,602,000) as the directors believe that there is insufficient certainty regarding the timing and likelihood of the Group being able to utilise the losses.

On 27 March 2018, 100% of the issued share capital of the company was acquired by the Carron Energy Ownership Trust ("the Trust"). The consideration consisted of an initial payment and deferred consideration, which will be settled by gifts from the company.

The Trust holds the shares for the benefit of the company's employees for the time being to have an interest in the company's business, a voice in its operations and a share in its profits.

The company made a contribution of £4,000,000 (2024: £4,000,000) during the year which has been treated as a contribution from equity.

The company expects to make further contribution to the Trust to assist the Trust to fulfill its future obligations from time to time.

A defined contribution pension scheme is operated for all qualifying employees. The assets of the scheme are held separately from those of the group in an independently administered fund.

At the year end the group had outstanding pension contributions of £33,000 (2024: £38,000), this amount being included within creditors due within one year.

The options outstanding at 31 March 2025 had an exercise price of £5.46, and a remaining contractual life of 10 years.

The weighted average fair value of options granted in the year was determined using the Black-Scholes option pricing model. The Black-Scholes model is considered to apply the most appropriate valuation method due to the relatively short contractual lives of the options and the requirement to exercise within a short period after the employee becomes entitled to the shares (the “vesting date”).

The profit and loss reserve represents cumulative profits or losses, net of dividends paid and other adjustments.

At the reporting end date the group had outstanding commitments for future minimum lease payments under non-cancellable operating leases, which fall due as follows:
