The results for the year are set out on page 9.

Qualifying third party indemnity provisions

RWE AG, the ultimate parent company, has made qualifying third party indemnity provisions for the benefit of the company’s directors during the year. These provisions remain in force at the date of approval of the financial statements.

Directors' insurance

The company maintains insurance policies on behalf of all the directors against liability arising from negligence, breach of duty and breach of trust in relation to the company.

Financial instruments
Financial risk management

The company has in place a risk management programme that seeks to limit the adverse effects on the financial performance of the company. The company's operations expose it to a few financial risks which are set out below.

Liquidity and cash flow risk

The company continues to receive financial support from the parent company, RWE Renewables UK Limited. It participates in the RWE Group cash pooling mechanism through the ultimate parent undertaking, RWE AG, providing short term liquidity within agreed limits. Due to these factors the company is not subject to liquidity or cash flow risk.

Interest rate risk

The company's exposure to interest rate risk is limited to interest charged on loans made from other group companies.

Currency risk

All of the company's transactions and balances are currently denominated in sterling and there is no foreign currency risk.

DIRECTORS' REPORT (CONTINUED)
FOR THE YEAR ENDED 31 DECEMBER 2025
- 2 -
Credit risk

The company has no significant exposure to credit risk.

Price risk

The company has no significant exposure to price risk.

Post reporting date events

Significant economic uncertainty exists resulting from the ongoing conflict in the Middle East. Uncertainty concerning the export of oil, gas and other commodities from the Persian Gulf is expected to lead to a global increase in inflation. The directors anticipate that this will adversely affect the prices at which the company procures goods and services, including through index-linked contracts, and have factored this into the business plan and forecasts. The company is also partially exposed to supply chain risks from wind farm components that are being manufactured in UAE. There is currently no disruption to the manufacturing process resulting from the conflict. However, the directors will continue to monitor developments and the risk to specific components while the uncertainty continues. The directors will also carefully consider the risks and appropriate mitigation strategies when awarding future contracts.

Future developments

The company intends to continue to hold and manage its investment in Norfolk Boreas Limited.

Independent auditor

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

Directors' confirmations

Each of the persons who is a director at the date of approval of this report confirms that:

 

 

This confirmation is given and should be interpreted in accordance with the provisions of s418 of the Companies Act 2006.

Going concern

The directors have fully considered the risks and uncertainties of the company's cash flow forecasts and projections, including the company’s commitment to provide support to its subsidiary and joint venture undertakings in accordance with the respective joint operation agreements for each entity.

Notwithstanding the net current liability position of the company at the year end, the going concern basis is considered to be appropriate by the directors as the RWE AG Group has committed to providing financial support for any financial obligations falling due for the 12 months following the date of the signing of the financial statements, by virtue of providing the company access to the RWE AG Group cash pooling mechanism along with long term loans where needed. The directors have made appropriate inquiries as to the ability of the group to provide such support.

On this basis, the directors have a reasonable expectation that the company will have adequate resources to continue in operational existence for the foreseeable future, being at least 12 months from date of signing. Thus, they continue to adopt the going concern basis in preparing the annual financial statements.

Small company provisions

In preparing this report, the directors have taken advantage of the small companies exemptions provided by section 414B of the Companies Act 2006 in not preparing a Strategic report.

DIRECTORS' RESPONSIBILITIES STATEMENT
FOR THE YEAR ENDED 31 DECEMBER 2025
- 4 -

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), including FRS 101 “Reduced Disclosure Framework”. 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:

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.

The directors are responsible for the maintenance and integrity of the corporate and financial information included on the company’s website. Legislation in the United Kingdom governing the preparation and dissemination of financial statements may differ from legislation in other jurisdictions.

Report on the audit of the financial statements
Opinion

 

In our opinion the financial statements of NB Holdco Limited (the ‘company’):

 

We have audited the financial statements which comprise:

 

 

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).

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 Financial Reporting Council’s (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.

Responsibilities of directors

 

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.

Auditor's 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 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.

 

A further description of our responsibilities for the audit of the financial statements is located on the FRC’s website at: www.frc.org.uk/auditorsresponsibilities. This description forms part of our auditor’s report.

Extent to which the audit was considered capable of detecting irregularities, including fraud

 

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 considered the nature of the company’s industry and its control environment, and reviewed the company’s documentation of their policies and procedures relating to fraud and compliance with laws and regulations. We also enquired of management and the directors about their own identification and assessment of the risks of irregularities, including those that are specific to the company’s business sector.

NB HOLDCO LIMITED
INDEPENDENT AUDITOR'S REPORT
TO THE MEMBERS OF NB HOLDCO LIMITED (CONTINUED)
- 7 -

We obtained an understanding of the legal and regulatory frameworks that the company operates in, and identified the key laws and regulations that:

 

We discussed among the audit engagement team including relevant internal specialists such as Tax, and IT specialists regarding the opportunities and incentives that may exist within the organisation for fraud and how and where fraud might occur in the financial statements.

 

In common with all audits under ISAs (UK), we are also required to perform specific procedures to respond to the risk of management override. In addressing the risk of fraud through management override of controls, we tested the appropriateness of journal entries and other adjustments; assessed whether the judgements made in making accounting estimates are indicative of a potential bias; and evaluated the business rationale of any significant transactions that are unusual or outside the normal course of business.

In addition to the above, our procedures to respond to the risks identified included the following:

 

Report on other legal and regulatory requirements

Opinions on other matters prescribed by the Companies Act 2006

 

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

 

 

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 any material misstatements in the directors’ report.

Matters on which we are required to report by exception

 

Under the Companies Act 2006 we are required to report in respect of the following matters if, in our opinion:

 

    

We have nothing to report in respect of these matters.

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.

Accounting policies
Company information

NB Holdco Limited is a private company limited by shares incorporated in England and Wales. The registered office is Windmill Hill Business Park, Whitehill Way, Swindon, Wiltshire, United Kingdom, SN5 6PB. The company's principal activities and nature of its operations are disclosed in the directors' report.

1.1
Basis of preparation

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 £000.

The financial statements have been prepared under the historical cost convention. The principal accounting policies adopted are set out below. These policies have been consistently applied to all the years presented, unless otherwise stated.

As permitted by FRS 101, the company has taken advantage of the relevant disclosure exemptions from the list below that are available under that standard in relation to share based payments, financial instruments, capital management, presentation of a cash flow statement, presentation of comparative information in respect of certain assets, standards not yet effective, impairment of assets, business combinations, discontinued operations, related party transactions, revenue from contracts with customers and leases.

 

Where required, equivalent disclosures are given in the group financial statements of RWE AG. The group financial statements of RWE AG are available to the public and can be obtained as set out in note 16.

Accounting policies
(Continued)
- 13 -

The company has taken advantage of the exemption under section 401 of the Companies Act 2006 not to prepare consolidated accounts. The financial statements present information about the company as an individual entity and not about its group.

 

NB Holdco Limited is a wholly owned subsidiary of RWE Renewables UK Limited and the results of NB Holdco Limited are included in the consolidated financial statements of RWE AG which are available from RWE AG, RWE Platz 1, 45141 Essen, Germany.

1.2
Going concern

The directors have fully considered the risks and uncertainties of the company's cash flow forecasts and projections, including the company’s commitment to provide support to its subsidiary and joint venture undertakings in accordance with the respective joint operation agreements for each entity. true

Notwithstanding the net current liability position of the company at the year end, the going concern basis is considered to be appropriate by the directors as the RWE AG Group has committed to providing financial support for any financial obligations falling due for the 12 months following the date of the signing of the financial statements, by virtue of providing the company access to the RWE AG Group cash pooling mechanism along with long term loans where needed. The directors have made appropriate inquiries as to the ability of the group to provide such support.

On this basis, the directors have a reasonable expectation that the company will have adequate resources to continue in operational existence for the foreseeable future, being at least 12 months from date of signing. Thus, they continue to adopt the going concern basis in preparing the annual financial statements.

1.3
Non-current investments

Interests in subsidiaries, associates and jointly controlled entities are initially measured at cost and subsequently measured at cost less any accumulated impairment losses. The investments are assessed for impairment at each reporting date and any impairment losses or reversals of impairment losses are recognised immediately in profit or loss.

1.4
Cash and cash equivalents

Cash and cash equivalents include cash in hand, deposits held at call with banks and other short-term liquid investments with original maturities of three months or less.

1.5
Financial assets

Financial assets are recognised in the company's statement of financial position when the company becomes party to the contractual provisions of the instrument. Financial assets are classified into specified categories, depending on the nature and purpose of the financial assets.

 

At initial recognition, financial assets classified as fair value through profit and loss are measured at fair value and any transaction costs are recognised in profit or loss. Financial assets not classified as fair value through profit and loss are initially measured at fair value plus transaction costs.

Financial assets held at amortised cost

Financial instruments are classified as financial assets measured at amortised cost where the objective is to hold these assets in order to collect contractual cash flows, and the contractual cash flows are solely payments of principal and interest. They arise principally from the provision of goods and services to customers (eg trade receivables). They are initially recognised at fair value plus transaction costs directly attributable to their acquisition or issue, and are subsequently carried at amortised cost using the effective interest rate method, less provision for impairment where necessary.

Accounting policies
(Continued)
- 14 -
Impairment of financial assets

Financial assets, other than those measured at fair value through profit or 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 of the investment have been affected.

 

For trade receivables and contract assets, the company applies the simplified approach permitted by IFRS 9, which requires expected lifetime losses to be recognised from initial recognition of the receivables – see note 11.

Derecognition of financial assets

Financial assets are derecognised only when the contractual rights to the cash flows from the asset expire, or when it transfers the financial asset and substantially all the risks and rewards of ownership to another entity.

1.6
Financial 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'.

Financial liabilities at fair value through profit or loss

Financial liabilities are classified as measured at fair value through profit or loss when the financial liability is held for trading. A financial liability is classified as held for trading if:

 

 

Financial liabilities at fair value through profit or loss are stated at fair value with any gains or losses arising on remeasurement recognised in profit or loss.

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.

Derecognition of financial liabilities

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

1.7
Equity instruments

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.

1.8
Taxation

The tax expense for the period comprises current and deferred tax. Tax is recognised through profit or loss, except to the extent that it relates to items recognised in other comprehensive income. In this case, the tax is also recognised in other comprehensive income.

Accounting policies
(Continued)
- 15 -
Current tax

The current income tax charge is calculated on the basis of the laws enacted or substantively enacted at the balance sheet date in the countries where the company operates and generates taxable income.

Deferred tax

Deferred income tax is recognised on temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the financial statements. Deferred income tax is determined using tax rates and laws that have been enacted or substantively enacted by the statement of financial position date and are expected to apply when the related deferred income tax asset is realised or the deferred income tax liability is settled.

Deferred income tax assets are recognised only to the extent that it is probable that future taxable profits will be available against which the temporary differences can be utilised.

Deferred income tax assets and liabilities are offset when there is a legally enforceable right to offset current tax assets against current tax liabilities and when the deferred income tax assets and liabilities relate to income taxes levied by the same taxation authority on either the same taxable entity or different taxable entities where there is an intention to settle the balance on a net basis.

2
Adoption of new and revised standards and changes in accounting policies

There are no amendments to accounting standards, or IFRIC interpretations that are effective for the year ended 31 December 2025 that have had a material impact on the company’s financial statements.

3
Critical accounting estimates and judgements

In the application of the company’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 if the revision affects only that period, or in the period of the revision and future periods if the revision affects both current and future periods.

 

There are no estimates or judgements which require further disclosure.

4
Employees

The company has no employees for the year under review (2024: none). Employees of the RWE AG group are employed by a fellow group company.

5
Directors' remuneration

The directors do not receive any remuneration from the company in respect of their services to the company. Instead, they are employed and paid by another related entity, RWE Renewables Management UK Limited. Due to the nature of the services provided and the number of entities to which it relates, it is not possible to meaningfully allocate the directors’ remuneration in respect of qualifying services to the company.

Pillar Two income taxes

The company has applied the temporary exception, introduced in May 2023, from the accounting requirements for deferred taxes in IAS 12, so that the company neither recognises nor discloses information about deferred tax assets and liabilities related to Pillar Two income taxes. The impact of Pillar Two legislation is not expected to be material.

Unprovided deferred tax

At the balance sheet date, the company has unused tax losses of £25k (2024: £28k) available for offset against future profits. No deferred tax asset has been recognised as it is not considered probable that there will be future taxable profits available.

Events after the reporting date

Significant economic uncertainty exists resulting from the ongoing conflict in the Middle East. Uncertainty concerning the export of oil, gas and other commodities from the Persian Gulf is expected to lead to a global increase in inflation. The directors anticipate that this will adversely affect the prices at which the company procures goods and services, including through index-linked contracts, and have factored this into the business plan and forecasts. The company is also partially exposed to supply chain risks from wind farm components that are being manufactured in UAE. There is currently no disruption to the manufacturing process resulting from the conflict. However, the directors will continue to monitor developments and the risk to specific components while the uncertainty continues. The directors will also carefully consider the risks and appropriate mitigation strategies when awarding future contracts.
