The directors present their annual report and financial statements for the year ended 31 December 2025. The comparative figures relate to the period from incorporation on 11 April 2024 to 31 December 2024 and therefore are not directly comparable with the current year.

The principal activity of the company continued to be that of design, construction, finance, operation and maintenance of the PV installation within the UK.

Review of the business and future developments

The Company was incorporated on 11 April 2024 and is wholly owned by HOCHTIEF Solarpartner GmbH, a German developer, constructor, owner and operator of large-scale solar projects in the EU based in Essen, Germany.

A HOCHTIEF-backed consortium has been announced recently as the preferred bidder for the 50-year PPP tender for a student accommodation project, procured by University of Staffordshire (SUSV project).

The project involves the development of a new student village at University of Staffordshire’s main campus, with the construction of 700 new rooms and the refurbishment of another 297. HOCHTIEF Solarpartner has been engaged by the Project SPC as the PV Contractor. This work is expected to be completed by September 2026 in time for the 2026/27 academic year.

HOCHTIEF Solarpartner will provide design, construction, finance, operation and maintenance of the PV installation for the SUSV project. All PV electricity produced will be supplied to SPV and also to the University for the duration of the initial contract (50 years), subject to a PPA.

The results for the year are set out on page 7.

No ordinary dividends were paid. The directors do not recommend payment of a final dividend.

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

Going concern

The Company’s business activities are detailed in the directors’ report. The directors have reviewed the budget for at least 12 months from the date of approval of these financial statements and the forecast for the remainder of the project.

The members’ are satisfied that sufficient funding, through HOCHTIEF PPP Solutions GmbH, is in place to reach practical completion and enter the operational phase of the project.

Having considered the risks and uncertainties of the business and their projections for the future performance of the company the directors have a reasonable expectation that the company has adequate resources to continue in operational existence for the foreseeable future. Accordingly, they have adopted the going concern basis in preparing these financial statements.

The auditor, RSM UK Audit LLP, is deemed to be reappointed under section 487(2) of the Companies Act 2006.

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 company’s auditor 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 company’s auditor is aware of that information.

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

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

United Kingdom company law requires the directors to prepare the directors report and the 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 company and of the profit or loss of the company 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;

• prepare the financial statements on the going concern basis unless it is inappropriate to presume that the company 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 enable them to ensure that the financial statements comply with the Companies Act 2006. They are also responsible for safeguarding the assets of the company and hence for taking reasonable steps for the prevention and detection of fraud and other irregularities.

We have audited the financial statements of HOCHTIEF Solarpartner UK Ltd (the 'company') for the year ended 31 December 2025 which comprise the profit and loss account, the balance sheet, the statement of changes in equity 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 101 Reduced Disclosure Framework (United Kingdom Generally Accepted Accounting Practice).

In our opinion the financial statements:

• give a true and fair view of the state of the company's affairs as at 31 December 2025 and of its 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 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 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 directors' report for the financial year for which the financial statements are prepared is consistent with the financial statements; and

• the directors' report has been prepared in accordance with applicable legal requirements.

In the light of the knowledge and understanding of the company and its environment obtained in the course of the audit, we have not identified material misstatements in 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, or returns adequate for our audit have not been received from branches not visited by us; or

• the 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.

• The directors were not entitled to prepare the financial statements in accordance with the small companies regime and take advantage of the small companies exemption from the requirement to prepare a strategic report or in preparing the directors report

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 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 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.

The extent to which our procedures are capable of detecting irregularities, including fraud, is detailed below.

Irregularities are instances of non-compliance with laws and regulations. The objectives of our audit are to obtain sufficient appropriate audit evidence regarding compliance with laws and regulations that have a direct effect on the determination of material amounts and disclosures in the financial statements, to perform audit procedures to help identify instances of non-compliance with other laws and regulations that may have a material effect on the financial statements, and to respond appropriately to identified or suspected non-compliance with laws and regulations identified during the audit.

In relation to fraud, the objectives of our audit are to identify and assess the risk of material misstatement of the financial statements due to fraud, to obtain sufficient appropriate audit evidence regarding the assessed risks of material misstatement due to fraud through designing and implementing appropriate responses and to respond appropriately to fraud or suspected fraud identified during the audit.

However, it is the primary responsibility of management, with the oversight of those charged with governance, to ensure that the entity's operations are conducted in accordance with the provisions of laws and regulations and for the prevention and detection of fraud.

In identifying and assessing risks of material misstatement in respect of irregularities, including fraud, the audit engagement team:

• obtained an understanding of the nature of the industry and sector, including the legal and regulatory framework that the company operates in and how the company is complying with the legal and regulatory framework;

• inquired of management, and those charged with governance, about their own identification and assessment of the risks of irregularities, including any known actual, suspected or alleged instances of fraud;

• discussed matters about non-compliance with laws and regulations and how fraud might occur including assessment of how and where the financial statements may be susceptible to fraud.

As a result of these procedures we consider the most significant laws and regulations that have a direct impact on the financial statements are FRS 101, the Companies Act 2006 and tax compliance regulations. We performed audit procedures to detect non-compliances which may have a material impact on the financial statements which included reviewing financial statement disclosures and reviewing tax computations prepared by taxation specialists.

The audit team did not identify any indirect laws and regulations that have a significant impact on the financial statements.

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 applicable to companies subject to the small companies regime.

HOCHTIEF Solarpartner UK Ltd is a private company limited by shares incorporated in England and Wales. The registered office is Whitehill House, Windmill Hill Business Park, Whitehill Way, Swindon, Wiltshire, England, SN5 6PE. The company's principal activities and nature of its operations are disclosed in the directors' report.

The financial statements have been prepared in accordance with Financial Reporting Standard 101 Reduced Disclosure Framework (FRS 101) and in accordance with applicable accounting standards.

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 £.

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

As permitted by FRS 101, the company has taken advantage of the following disclosure exemptions from the requirements of IFRS:

• inclusion of an explicit and unreserved statement of compliance with IFRS;

• presentation of a statement of cash flows and related notes;

• disclosure of the objectives, policies and processes for managing capital;

• disclosure of key management personnel compensation;

• disclosure of the categories of financial instrument and the nature and extent of risks arising on these financial instruments;

Where required, equivalent disclosures are given in the group accounts of HOCHTIEF PPP Solutions GmbH. The group accounts of HOCHTIEF PPP Solutions GmbH are available to the public and can be obtained as set out in note note,note76.

The directors have at the time of approving the financial statements, a reasonable expectation that the truecompany has adequate resources to continue in operational existence for the foreseeable future.

In addition, the parent company has committed to provide continued financial support for the company's bidding activity for a period of at least 12 months from the date of approval of these financial statements.

Thus the directors continue to adopt the going concern basis of accounting in preparing the financial statements.

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: As the solar panels are not yet operational no depreciation has not been applied. Once operational the following straight line depreciation rates are applied:

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.

At each reporting end date, the company reviews the carrying amounts of its tangible 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.

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.

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.

Cash and cash equivalents include cash in hand, deposits held at call with banks, other short-term liquid investments with original maturities of three months or less, and bank overdrafts. Bank overdrafts are shown within borrowings in current liabilities.

The company recognises financial debt when the company becomes a party to the contractual provisions of the instruments. Financial liabilities are classified as either 'financial liabilities at fair value through profit or loss' or 'other financial liabilities'.

Other financial liabilities, including borrowings, trade payables and other short-term monetary liabilities, are initially measured at fair value net of transaction costs directly attributable to the issuance of the financial liability. They are subsequently measured at amortised cost using the effective interest method. For the purposes of each financial liability, interest expense includes initial transaction costs and any premium payable on redemption, as well as any interest or coupon payable while the liability is outstanding.

Financial liabilities are derecognised when, and only when, the company’s obligations are discharged, cancelled, or they expire.

Equity instruments issued by the company are recorded at the proceeds received, net of direct issue costs. Dividends payable on equity instruments are recognised as liabilities once they are no longer at the discretion of the company.

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 company’s liability for current tax is calculated using tax rates that have been enacted or substantively enacted by the reporting end date.

Deferred tax is the tax expected to be payable or recoverable on differences between the carrying amounts of assets and liabilities in the financial statements and the corresponding tax bases used in the computation of taxable profit, and is accounted for using the balance sheet liability method. Deferred tax liabilities are generally recognised for all taxable temporary differences and deferred tax assets are recognised to the extent that it is probable that taxable profits will be available against which deductible temporary differences can be utilised. Such assets and liabilities are not recognised if the temporary 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 when the company has 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 inventories 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.

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

The charge for the year can be reconciled to the loss per the profit and loss account as follows:

Unused tax losses of £11,243 were carried forward at the end of the current period. An associated deferred tax asset of £3,454 has been recognised and will be applied to future profits.

Solar panels are classified as Plant & Machinery and are depreciated on a straight-line basis over their estimated useful life of 25 years, reflecting the estimated replacement cycle under the contractual arrangement with Willmott Dixon.

Additions during the year relate to capital expenditure incurred in connection with the development and installation of the solar panels at the University of Staffordshire as part of the SUSV project

As of 31 Demeber 2025, the solar panels are not operational; therefore have not been depreciated. Depreciation will commence once the assets are commissionised.

On 15 September 2025 the company entered into a loan agreement with its parent undertaking for £475,000. The loan carries a fixed interest rate of 8% per annum. Interest is accrued and payable in accordance with the terms of the agreement.

The following are the major deferred tax liabilities and assets recognised by the company and movements thereon during the current and prior reporting period.

During the year, the company issued 174,900 ordinary shares of £1 each, for total consideration of £174,900.
