GROUP STRATEGIC REPORT
FOR THE YEAR ENDED 31 DECEMBER 2024

Introduction
 
The directors present the financial statements of Rotech International Limited.  

The principal activity of Rotech International Limited, the ultimate parent company, and its subsidiaries (the Group), is the research, development, manufacturing, and provision of specialised subsea excavation services for the global offshore energy industries.

Business Model and Strategy
 
Rotech International is the ultimate parent company for Rotech Holdings Limited which acts as the central strategic hub for the Group and provides a vertically integrated R&D, manufacturing, and service model.

The Integrated Business Model:
R&D and Manufacturing (Rotech Holdings/Engineering): Conducts research and development into proprietary subsea excavation products to optimise them for market needs, and manufactures this equipment at its facilities in Aberdeen, Scotland.
Service Delivery (Rotech Subsea): Deploys the patented, manufactured equipment to clients globally, generating the majority of the Group's turnover.

Our core offering is thus founded on the creation of proprietary technology and its application to precision excavation, essential for enabling the installation, maintenance, and decommissioning of critical infrastructure.

Strategic Pillars:
Leading the Energy Transition: Prioritise investment and service delivery to support the rapid growth of the offshore renewable sector.
Integrated Asset-Led Growth: The Group continually invests in the expansion of its patented fleet, manufactured internally by Rotech Engineering Limited, driving capacity and technological differentiation for the entire Group.
Global Penetration: Expand the Group’s service presence in high-growth international markets. This model successfully targets international contracts, with 87.7% of consolidated turnover generated outside the UK.

Fair Review of the Business (Consolidated)

Performance Summary
The financial year 2024 represented a period of exceptional consolidated growth and successful strategic execution, validating the Group's integrated, asset-led investment strategy.

Geographical Analysis
The Group's strong performance is underpinned by the operational success of Rotech Subsea across international markets. A total of 87.7% of consolidated turnover was generated outside the UK, demonstrating both the global demand for our specialized services and the successful execution of our global penetration strategy. Overseas growth was particularly pronounced, with turnover in Asia increasing by 74% and Europe by 31%.

GROUP STRATEGIC REPORT (CONTINUED)
FOR THE YEAR ENDED 31 DECEMBER 2024

Analysis of Financial Performance
Consolidated turnover increased by an impressive 62%. This significant uplift is seen by the Directors as a direct validation that the continued investment in the proprietary fleet, manufactured by Rotech Engineering, is successfully capturing market share and meeting rising international demand.

Segmental Review
The Group’s focus on the offshore energy industries yielded the following consolidated revenue split:
Offshore Wind: Maintained its dominant position, accounting for 81% of total turnover, reinforcing the Group's alignment with the global energy transition.
Energy Transition, Power and Utilities: Contributed the remaining 19%, encompassing services related to specialised seabed preparation for inter-connector cables, power infrastructure, and other energy transition projects.

Position and Investment

The vertical integration of the Group ensures that capital investment is tightly aligned with operational deployment.

Fleet Investment

As the manufacturing and R&D hub, Rotech Holdings Limited committed £3.00m (£2.40m in 2023) to the construction of new equipment through Rotech Engineering Limited. This brings the total cost of the Group’s subsea excavation fleet to £14,869,965. This investment is central to the Group’s strategy, as it ensures the fleet has the necessary capacity and technological capability to win large-scale, international contracts.

Competitive Advantage

The Group’s competitive differentiation is primarily derived from its strong portfolio of international patents covering the subsea excavation equipment, which is developed and manufactured internally. This intellectual property barrier provides a significant advantage in terms of unmatched efficiency and operational capability in the market.

Principal Risks and Uncertainties
 
The Board has assessed the principal risks that could affect the Group’s future development:

Market Concentration Risk: The high concentration of consolidated revenue in the offshore wind sector (81%) exposes the Group to risks from regulatory and investment policy changes. This is mitigated by pursuing contracts in diversified sectors and through continued geographical expansion, while leveraging core technology for counter-cyclical decommissioning and maintenance services.
Vertical Integration / Manufacturing Risk: The reliance on internal manufacturing (Rotech Engineering Limited) for the proprietary fleet introduces risk related to production capacity, rising input costs, and skill shortages in specialised manufacturing. This is mitigated by rigorous planning and strategic investment in Rotech Engineering's manufacturing capacity in Aberdeen.
Geopolitical Risk: Geopolitical tensions have the potential to disrupt international activity. However, the Group is able to mitigate against localised uncertainties and regulatory hurdles due to the inherent mobility of the service fleet (Rotech Subsea) and its operational capability to re-deploy assets across multiple global geographies as required.

GROUP STRATEGIC REPORT (CONTINUED)
FOR THE YEAR ENDED 31 DECEMBER 2024

Outlook
 
The Directors are highly optimistic following the exceptional consolidated performance of 2024. The significant investment in proprietary equipment, driven by Rotech Engineering, is validated by the 62% turnover growth, and market fundamentals, particularly in offshore wind, remain strong. The focus for 2025 and beyond will be to expand the size and breadth of the subsea excavation fleet and optimise its utilisation, while continuing to penetrate high-growth International markets to maintain a high-growth trajectory.


This report was approved by the board and signed on its behalf.

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 applicable law and United Kingdom Accounting Standards (United Kingdom Generally Accepted Accounting Practice), including Financial Reporting Standard 102 ‘The Financial Reporting Standard applicable in the UK and Republic of Ireland'.

select suitable accounting policies for the Group's financial statements and then apply them consistently;

make judgements and accounting estimates that are reasonable and prudent;


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

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

INDEPENDENT AUDITORS' REPORT TO THE MEMBERS OF ROTECH INTERNATIONAL LIMITED
 

Opinion


We have audited the financial statements of Rotech International Limited (the 'parent company') and its subsidiaries (the 'Group') for the year ended 31 December 2024, which comprise the Consolidated statement of comprehensive income, the Consolidated analysis of net debt, the Consolidated Balance Sheet, the Company Balance Sheet, the Consolidated Statement of Cash Flows, the Consolidated Statement of Changes in Equity, the Company Statement of Changes in Equity and the related notes, including a summary of significant accounting policiesThe 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 of the parent company's affairs as at 31 December 2024 and of the Group's profit 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 Auditors' responsibilities for the audit of the financial statements section of our report. We are independent of the Group in accordance with the ethical requirements that are relevant to our audit of the financial statements in the United Kingdom, including the Financial Reporting Council'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 or the 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 Auditors' report thereon. The directors are responsible for the other information contained within the Annual ReportOur 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.


Opinion on other matters prescribed by the Companies Act 2006
 

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


the information given in the Group 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 Group strategic report and the Directors' report have been prepared in accordance with applicable legal requirements.


Matters on which we are required to report by exception
 

In the light of the knowledge and understanding of the Group and the parent company and its environment obtained in the course of the audit, we have not identified material misstatements in the Group 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.


Responsibilities of directors
 

As explained more fully in the Directors' responsibilities statement set out on page 5, 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 Group's and 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 Group or the parent company or to cease operations, or have no realistic alternative but to do so.

INDEPENDENT AUDITORS' REPORT TO THE MEMBERS OF ROTECH INTERNATIONAL LIMITED (CONTINUED)

Auditors' responsibilities for the audit of the financial statements
 

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 Auditors' 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 Group financial statements.


Irregularities, including fraud, are instances of non-compliance with laws and regulations. We design procedures in line with our responsibilities, outlined above, 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:

We obtained an understanding of the legal and regulatory frameworks within which the company operates, focusing on those laws and regulations that have a direct effect on the determination of material amounts and disclosures in the financial statements. 

The laws and regulations we considered in this context were the Companies Act 2006 and Taxation legislation.

We identified the greatest risk of material impact on the financial statements from irregularities including fraud to be:

Management override of controls to manipulate the company’s key performance indicators to meet targets;
Timing and completeness of revenue recognition;
Management judgement applied in calculating provisions; and
Compliance with relevant laws and regulations which directly impact the financial statements and those that the company needs to comply with for the purpose of trading

Our audit procedures to respond to these risks included:

Testing of journal entries and other adjustments for appropriateness;
Evaluating the business rationale of significant transactions outside the normal course of business;
Reviewing judgments made by management in their calculation of accounting estimates for potential management bias;
Enquiries of management about litigation and claims and inspection of relevant correspondence;
Reviewing legal and professional fees to identify indications of actual or potential litigation, claims and any non-compliance with laws and regulations;
Analytical procedures to identify any unusual or unexpected trends or relationship; and
Reviewing minutes of meetings of those charged with governance to identify any matters indicating actual or potential fraud


Because of the inherent limitations of an audit, there is a risk that we will not detect all irregularities, including those leading to a material misstatement in the financial statements or non-compliance with regulation. This risk increases the more that compliance with a law or regulation is removed from the events and transactions reflected in the financial statements, as we will be less likely to become aware of instances of non-compliance. The risk is also greater regarding irregularities occurring due to fraud rather than error, as fraud involves intentional concealment, forgery, collusion, omission or misrepresentation.


A further description of our responsibilities for the audit of the financial statements is located on the Financial Reporting Council's website at: www.frc.org.uk/auditorsresponsibilities. This description forms part of our Auditors' report.

NOTES TO THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 31 DECEMBER 2024

1.


General information

Rotech International Limited is a limited company incorporated in Scotland. The registered office is 28 Albyn Place, Aberdeen, AB10 1YL. The principal activity of the company during the period was the development and promotion of the group's research and development work in the offshore oil industry and renewable energy market with a view to subsequent commercialisation, licence or sale of the developed technologies. 


2.


Going concern

At 31 December 2024 the group has net assets of £6,956,791, net assets before Loan Note Instruments of £16,956,791, net current assets of £8,577,637.

Liabilities for group and company include £10,000,000 of Loan Note Instruments due to 3 individuals, including a director of the group and close family members, which fall due in installments over a period of 10 years. The individuals have signaled their continued support for the group in recent years by agreeing to extend the repayment period for capital and interest payments (note 25) and have provided written confirmation signaling their intention to not to call for payments as they fall due if it were to threaten the ability of the group to operate as a going concern.

Following the year end, the group has achieved profitable trading in the year to December 2025 with further profitable trading and cash generation projected beyond this. This projection is based on the investments made in the group in recent years and a strong diversified order book. As part of this assessment management have considered possible downside scenarios and concluded that there are adequate reserves in place to meet obligations as they fall due.

Given these circumstances, the directors consider the group has adequate working capital to execute its operations over the next 12 months from the approval of these financial statements and have therefore prepared the financial statements on a going concern basis.
  

3.Accounting policies

 
3.1

Basis of preparation of financial statements

The financial statements have been prepared under the historical cost convention unless otherwise specified within these accounting policies and in accordance with Financial Reporting Standard 102, the Financial Reporting Standard applicable in the UK and the Republic of Ireland and the Companies Act 2006.

The preparation of financial statements in compliance with FRS 102 requires the use of certain critical accounting estimates. It also requires Group management to exercise judgement in applying the Group's accounting policies (see note 4).

The company has taken advantage of the exemption allowed under section 408 of the Companies Act 2006 and has not presented its own Statement of comprehensive income in these financial statements.

The following principal accounting policies have been applied:

 
3.2

Basis of consolidation

The consolidated financial statements present the results of the company and its own subsidiaries ("the Group") as if they form a single entity using the acquisition method. Intercompany transactions and balances between group companies are therefore eliminated in full.

NOTES TO THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 31 DECEMBER 2024

3.Accounting policies (continued)

 
3.3

Revenue

Revenue is recognised to the extent that it is probable that the economic benefits will flow to the Group and the revenue can be reliably measured. Revenue is measured as the fair value of the consideration received or receivable, excluding discounts, rebates, value added tax and other sales taxes. The following criteria must also be met before revenue is recognised:

Rendering of services

Revenue from a contract to provide services is recognised in the period in which the services are provided in accordance with the stage of completion of the contract when all of the following conditions are satisfied:
the amount of revenue can be measured reliably;
it is probable that the Group will receive the consideration due under the contract;
the stage of completion of the contract at the end of the reporting period can be measured reliably; and
the costs incurred and the costs to complete the contract can be measured reliably.

On long-term contracts, turnover is calculated as that proportion of total contract value which costs incurred to date bear to total expected costs for that contract. Revenues derived from variations on contracts are recognised only when they have been accepted by the customer. 

Profit on long-term contracts is taken as the work is carried our if the final outcome can be assessed with reasonable certainty. The profit included is calculated on a prudent basis to reflect the proportion of the work carried out at the year end, by recording turnover and related costs as contract activity progresses. Full provision is made for losses on all contracts in the year in which they are first foreseen. 

 
3.4

Intangible assets

Goodwill

Goodwill represents the difference between amounts paid on the cost of a business combination and the acquirer’s interest in the fair value of the Group's share of its identifiable assets and liabilities of the acquiree at the date of acquisition. Subsequent to initial recognition, Goodwill is measured at cost less accumulated amortisation and accumulated impairment losses. Goodwill is amortised on a straight line basis to the Consolidated statement of comprehensive income over a period of 10 years.

Other intangible assets

Development costs are capitalised within intangible assets where they can be identified with a specific product or project anticipated to produce future benefits, and are amortised on the straight line basis over the anticipated life of the benefits arising from the completed product or project. 

Development costs are reviewed annually and where future benefits are deemed to have ceased or to be in doubt, the balance of any related research and development is written off to the Profit and loss account. 

Patent fees are capitalised at cost and amortised over the life of the patent to which they relate. 

All intangible assets are considered to have a finite useful life. If a reliable estimate of the useful life cannot be made, the useful life shall not exceed five years.

NOTES TO THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 31 DECEMBER 2024

3.Accounting policies (continued)

 
3.5

Tangible fixed assets

Tangible fixed assets under the cost model are stated at historical cost less accumulated depreciation and any accumulated impairment losses. Historical cost includes expenditure that is directly attributable to bringing the asset to the location and condition necessary for it to be capable of operating in the manner intended by management.

Depreciation is charged so as to allocate the cost of assets less their residual value over their estimated useful lives, using the straight-line method and the reducing balance method.

Depreciation is provided on the following basis:

Freehold property
-
2% straight line
Plant and machinery
-
20 - 33% straight line and 10% reducing balance
Motor vehicles
-
33% straight line and 25% reducing balance
Fixtures and fittings
-
33 - 50% straight line and 25% reducing balance
Computer equipment
-
25% reducing balance
Assets under construction
-
Not depreciated

The assets' residual values, useful lives and depreciation methods are reviewed, and adjusted prospectively if appropriate, or if there is an indication of a significant change since the last reporting date.

Gains and losses on disposals are determined by comparing the proceeds with the carrying amount and are recognised in profit or loss.

Depreciation of tangible fixed assets is applied from the time they are made available for use.

 
3.6

Valuation of investments

Investments in subsidiaries are measured at cost less accumulated impairment.

 
3.7

Stocks

Stocks are stated at the lower of cost and net realisable value, being the estimated selling price less costs to complete and sell.

At each balance sheet date, stocks are assessed for impairment. If stock is impaired, the carrying amount is reduced to its selling price less costs to complete and sell. The impairment loss is recognised immediately in profit or loss.

 
3.8

Debtors

Short term debtors are measured at transaction price, less any impairment.

 
3.9

Cash and cash equivalents

Cash is represented by cash in hand and deposits with financial institutions repayable without penalty on notice of not more than 24 hours. Cash equivalents are highly liquid investments that mature in no more than three months from the date of acquisition and that are readily convertible to known amounts of cash with insignificant risk of change in value.

In the Consolidated statement of cash flows, cash and cash equivalents are shown net of bank overdrafts that are repayable on demand and form an integral part of the Group's cash management.

NOTES TO THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 31 DECEMBER 2024

3.Accounting policies (continued)

 
3.10

Financial instruments

Basic financial assets

Basic financial assets, which include trade and other debtors, cash and bank balances, are initially measured at their transaction price (adjusted for transaction costs except in the initial measurement of financial assets that are subsequently measured at fair value through profit and loss) and are subsequently carried at their amortised cost using the effective interest method, less any provision for impairment, 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.

Discounting is omitted where the effect of discounting is immaterial. The Group's cash and cash equivalents, trade and most other debtors due with the operating cycle fall into this category of financial instruments.

Other financial assets

Other financial assets, which includes investments in equity instruments which are not classified as subsidiaries, associates or joint ventures, are initially measured at fair value, which is normally the recognised transaction price. Such assets are subsequently measured at fair value with the changes in fair value being recognised in the profit or loss. Where other financial assets are not publicly traded, hence their fair value cannot be measured reliably, they are measured at cost less impairment.

Impairment of financial assets

At the end of each reporting period financial assets measured at amortised cost are assessed for objective evidence of impairment. 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. 

Financial assets are impaired when events, subsequent to their initial recognition, indicate the estimated future cash flows derived from the financial asset(s) have been adversely impacted. The impairment loss will be the difference between the current carrying amount and the present value of the future cash flows at the asset(s) original effective interest rate.

If there is a favourable change in relation to the events surrounding the impairment loss then the impairment can be reviewed for possible reversal. The reversal will not cause the current carrying amount to exceed the original carrying amount had the impairment not been recognised. The impairment reversal is recognised in the profit or loss.

Basic financial liabilities

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 the deduction of all its liabilities.

Basic financial liabilities, which include trade and other creditors, bank loans, other loans and loans due to fellow group companies are initially measured at their transaction price (adjusting for transaction costs except in the initial measurement of financial liabilities that are subsequently measured at fair value through profit and loss). When this constitutes a financing transaction, whereby the debt instrument is measured at the present value of the future payments discounted at a market rate of interest, discounting is omitted where the effect of discounting is immaterial.

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

NOTES TO THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 31 DECEMBER 2024

3.Accounting policies (continued)


3.10
Financial instruments (continued)

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

Derecognition of financial instruments

Derecognition of financial assets

Financial assets are derecognised when their contractual right to future cash flow expire, or are settled, or when the Group transfers the asset and substantially all the risks and rewards of ownership to another party. If significant risks and rewards of ownership are retained after the transfer to another party, then the Group will continue to recognise the value of the portion of the risks and rewards retained.

Derecognition of financial liabilities

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

 
3.11

Creditors

Short-term creditors are measured at the transaction price. Other financial liabilities, including bank loans, are measured initially at fair value, net of transaction costs, and are measured subsequently at amortised cost using the effective interest method.

 
3.12

Foreign currency translation

Functional and presentation currency

The company's functional and presentational currency is GBP.

Transactions and balances

Foreign currency transactions are translated into the functional currency using the spot exchange rates at the dates of the transactions.

At each period end foreign currency monetary items are translated using the closing rate. Non-monetary items measured at historical cost are translated using the exchange rate at the date of the transaction and non-monetary items measured at fair value are measured using the exchange rate when fair value was determined.

 
3.13

Finance costs

Finance costs are charged to profit or loss over the term of the debt using the effective interest method so that the amount charged is at a constant rate on the carrying amount. Issue costs are initially recognised as a reduction in the proceeds of the associated capital instrument.

NOTES TO THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 31 DECEMBER 2024

3.Accounting policies (continued)

 
3.14

Operating leases: Lessee

Rentals paid under operating leases are charged to profit or loss on a straight-line basis over the lease term.

Benefits received and receivable as an incentive to sign an operating lease are recognised on a straight line basis over the period until the date of the rent is expected to be adjusted to the prevailing market rate. 

 
3.15

Leased assets: Lessee

Assets obtained under hire purchase contract are capitalised as tangible fixed assets. Assets acquired by hire purchase are depreciated over their useful lives. Obligations under such agreements are included in creditors net of the finance charge allocated to future periods. The finance element of the rental payment is charged to the consolidated statement of comprehensive income so as to produce a constant periodic rate of charge on the net obligation outstanding in each period. 

  
3.16

Pensions

The Group contributes to a defined contribution plan for its employees. A defined contribution plan is a pension plan under which the Group pays fixed contributions into a separate entity. Once the contributions have been paid the Group has no further payment obligations.

The contributions are recognised as an expense in the Consolidated statement of comprehensive income when they fall due. Amounts not paid are shown in accruals as a liability in the Balance sheet. The assets of the plan are held separately from the Group in independently administered funds.

 
3.17

Interest income

Interest income is recognised in profit or loss using the effective interest method.

 
3.18

Borrowing costs

All borrowing costs are recognised in profit or loss in the year in which they are incurred.

ROTECH INTERNATIONAL LIMITED
 

NOTES TO THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 31 DECEMBER 2024

3.Accounting policies (continued)

 
3.19

Current and deferred taxation

The tax expense for the year comprises current and deferred tax. Tax is recognised in profit or loss except that a charge attributable to an item of income and expense recognised as other comprehensive income or to an item recognised directly in equity is also recognised in other comprehensive income or directly in equity respectively.

The current income tax charge is calculated on the basis of tax rates and laws that have been enacted or substantively enacted by the balance sheet date in the countries where the company and the Group operate and generate income.

Deferred tax balances are recognised in respect of all timing differences that have originated but not reversed by the balance sheet date, except that:
The recognition of deferred tax assets is limited to the extent that it is probable that they will be recovered against the reversal of deferred tax liabilities or other future taxable profits;
Any deferred tax balances are reversed if and when all conditions for retaining associated tax allowances have been met; and
Where they relate to timing differences in respect of interests in subsidiaries, associates, branches and joint ventures and the Group can control the reversal of the timing differences and such reversal is not considered probable in the foreseeable future.

Deferred tax balances are not recognised in respect of permanent differences except in respect of business combinations, when deferred tax is recognised on the differences between the fair values of assets acquired and the future tax deductions available for them and the differences between the fair values of liabilities acquired and the amount that will be assessed for tax. Deferred tax is determined using tax rates and laws that have been enacted or substantively enacted by the balance sheet date.


 
3.20

Research and development

In the research phase of an internal project it is not possible to demonstrate that the project will generate future economic benefits and hence all expenditure on research shall be recognised as an expense when it is incurred. Intangible assets are recognised from the development phase of a project if and only if certain specific criteria are met in order to demonstrate the asset will generate probable future economic benefits and that its cost can be reliably measured. The capitalised development costs are subsequently amortised on a straight line basis over their useful economic lives.

If it is not possible to distinguish between the research phase and the development phase of an internal project, the expenditure is treated as if it were all incurred in the research phase only.

Judgements in applying accounting policies and key sources of estimation uncertainty

The preparation of financial statements, requires management to make judgements, estimates and assumptions that affect the amounts reported for assets and liabilities as at the Statement of financial position date and the amounts reported during the period for revenue and costs. However, the nature of estimation means that actual outcomes could differ from those estimates. Estimates and judgements are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. The following judgements and estimates have had the most significant impact on amounts recognised in the financial statement.

Useful economic lives of tangible assets

The annual depreciation charge for tangible assets is sensitive to changes in the useful economic lives and residual values of the assets. Useful lives and residual values are reassessed annually. They are assessed where necessary to reflect current estimates based on economic utilisation and physical condition.

Amounts due to group and related undertakings are not under a formal lending arrangement, however the directors believe the material element of this balance will be payable in greater than one year and therefore have been included within amounts due after more than one year.

The other loans attract interest at a fixed rate of 5% per annum and are repayable in installments with £5,000,000 originally falling due on 30 June 2022 and installments of £1,000,000 falling due on an annual basis following this.

However the groups loan note holders have pledged their continued support for the group (note 2) and confirmed no amounts will be required to be repaid if it were to threaten the ability of the group to operate as a going concern, and accordingly all amounts are recorded within non-current liabilities.

The terms of the loan notes are that interest accruing from the date of the loans being issued until 30 June 2019 is only payable under certain conditions, however the loan note holders have extended this period, and applies to all interest accrued to 31 December 2023 see note 25 for details.

The loan note holders hold a floating charge over the whole assets of the group and a standard security over the office block, workshop and yard at Whitemyres Avenue in respect of the obligations due under the loan notes and certain other arrangements between the group and a third party under the control of the loan note holders.

Included in loan notes payable are amounts totaling £1,145,000 and included within accruals are relatted interest amounts toalling £41,422 due to a director.

Regarding the bank loan, payments commenced in June 2022 consisting of 60 monthly installments. Interest is charged at a margin of 2.68% over base rate.
