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

The principal activity of the company is to act as an intermediary holding company within the APi Dutch Holdco B.V. group, a group that is engaged in the manufacture and design of fire protection systems and equipment. There have not been any significant changes in the company’s principal activities in the year under review. The directors are not aware, at the date of this report, of any likely major changes to the company’s principal activities in the next year. The company generated a net loss of £145,689 in 2025 (2024: £167,605 loss) mainly driven by unrealised foreign exchange losses on intercompany loans and operating expenses associated with the loan. This is considered to be the company’s main KPI.

The company is an intermediary holding company in the APi Dutch Holdco B.V. Group and is the immediate parent company of the UK trading entity, Knowsley S.K. Limited. As such, it is exposed to the financial risks of changes in foreign currency exchange rates. The use of financial derivatives is governed by the company’s policies approved by the board of directors which provide written principles on the use of financial derivatives to manage these risks. The company does not use derivative financial instruments for speculative purposes

The company generated a net loss of £145,689 in 2025 (2024: £167,604 loss).

No dividend was received from Knowsley S.K. Limited during the year 2025 (2024: nil).

No dividend was declared to SK Firesafety Group B.V. during the year 2025 (2024: nil).

No dividends were proposed after the year-end.

EU referendum

The company is affected by the result of the EU referendum, which has had an impact on the financial and currency exchange markets. This is not estimated to materially affect the amount of expected credit in the market or the operations of the company going forward other than currency exchange impact on the intercompany loan denominated in Euro.

Political and charitable contributions

The company made no political or charitable contributions during the year (2024: nil).

On behalf of the board

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

The principal activity of the company continued to be that of an intermediate holding company.

No dividends will be distributed for the year ended 31 December 2025.

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:

DJH Audit Limited has indicated its willingness to be reappointed for another term and appropriate arrangements are being made for it to be deemed reappointed as auditor in the absence of an Annual General Meeting.

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

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

• 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.

Under 414C (11) of the Companies Act 2006 the directors have opted to disclose information regarding principal risks and uncertainties, results and dividends and future developments in the Strategic Report.

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.

After making enquiries and based on the assumptions outlined in the Accounting Policies, the directors have a reasonable expectation that the company has adequate resources to continue in operational existence for the foreseeable future. The company also has sufficient financial support from its ultimate holding company.

The directors have assessed the impact of rising energy costs and other macroeconomic factors, including inflation on all aspects of the business, focusing specifically on operations and cash flows of the company. Revised forecasts have been made with stress-testing carried out, including assessing the levels of cash and available finance for the company.

Following a review of these forecasts and sensitivities and having considered the letter of support received from API Group Dutch Holdco B.V., the directors have concluded that the company is a going concern and accordingly have prepared the financial statements on this basis. Further details regarding the adoption of the going concern basis can be found in note 1 of the financial statements.

We have audited the financial statements of Knowsley SK Holding Limited (the 'company') for the year ended 31 December 2025 which comprise the statement of income and retained earnings, the statement of financial position and notes to the financial statements, including significant accounting policies. The financial reporting framework that has been applied in their preparation is applicable law and United Kingdom Accounting Standards, including Financial Reporting Standard 102 The Financial Reporting Standard applicable in the UK and Republic of Ireland (United Kingdom Generally Accepted Accounting Practice).

In our opinion the financial statements:

• give a true and fair view of the state of the 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 strategic report and the directors' report for the financial year for which the financial statements are prepared is consistent with the financial statements; and

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

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

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

• adequate accounting records have not been kept, 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.

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.

As part of our planning process:

- We enquired of management the systems and controls the company has in place, the areas of the financial statements that are mostly susceptible to the risk of irregularities and fraud, and whether there was any known, suspected or alleged fraud. The company did not inform us of any known, suspected or alleged fraud.

- We obtained an understanding of the legal and regulatory frameworks applicable to the company. We determined that the following were most relevant: FRS 102 and Companies Act 2006.

- We considered the incentives and opportunities that exist in the company, including the extent of management bias, which present a potential for irregularities and fraud to be perpetuated, and tailored our risk assessment accordingly.

- Using our knowledge of the company, together with the discussions held with the company at the planning stage, we formed a conclusion on the risk of misstatement due to irregularities including fraud and tailored our procedures according to this risk assessment.

The key procedures we undertook to detect irregularities including fraud during the course of the audit included:

- Identifying and testing journal entries, in particular those that were significant or unusual.

- Reviewing the financial statement disclosures and determining whether accounting policies have been appropriately applied.

- Reviewing and challenging the assumptions and judgements used by management in their significant accounting estimates, in particular in respect of impairment of investments in subsidiaries.

- Assessing the extent of compliance, or lack of, with the relevant laws and regulations.

- Obtaining third-party confirmation of material bank balances.

- Documenting and verifying all significant related party balances and transactions.

Owing to the inherent limitations of an audit, there is an unavoidable risk that we may not have detected some material misstatements in the financial statements even though we have properly planned and performed our audit in accordance with auditing standards. The primary responsibility for the prevention and detection of irregularities and fraud rests with the directors.

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

Use of our report

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

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

Knowsley SK Holding Limited is a private company limited by shares incorporated in England and Wales. The registered office is Centrepoint, Marshall Stevens Way, Trafford Park, Manchester, United Kingdom, M17 1AE.

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

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

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

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

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

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

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

The financial statements contain information about Knowsley SK Holdings Limited as an individual company and no not contain consolidated financial information as the parent of a group. The company is exempt under Section 399(2A) of the Companies Act 2006 from the requirements to prepare consolidated financial statements.

The company's business activities, together with the factors likely to affect its future development, performance and position are set out in the Strategic Report on page true1. The company's principal activity is that of a holding company and as such, the key basis for continuing as a going concern is the profitability and cash generating nature of its subsidiary of which the company's directors are also directors.

After making enquiries, the directors believe that the company has adequate resources to continue in operational existence for at least 12 months from the approval date of these financial statements.

The directors have received confirmation that APi Group Dutch Holdco B.V., the company's ultimate holding company, will continue to provide the necessary level of support to enable it to continue to operate for at least 12 months from the approval date of these financial statements. As referenced in the directors' report the directors have assessed the impact of rising energy costs and other macroeconomic factors, including inflation on all aspects of the business, focusing specifically on the operations and cash flows of the company. The directors have stress-tested these forecasts assuming a significant reduction in revenue, offset by identified and actioned operational and capital expenditure savings.

Taking all those factors into account, the directors have a reasonable expectation that the company has adequate resources to continue in operational existence for the foreseeable future and therefore continue to adopt the going concern basis in preparing the financial statements.

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.

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

Financial instruments are recognised in the company's statement of financial position when the company becomes party to the contractual provisions of the instrument.

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

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

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

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

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

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

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

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

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

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

Derivatives, including interest rate swaps and forward foreign exchange contracts, are not basic financial instruments. Derivatives are initially recognised at fair value on the date a derivative contract is entered into and are subsequently re-measured at their fair value. Changes in the fair value of derivatives are recognised in profit or loss in finance costs or finance income as appropriate, unless hedge accounting is applied and the hedge is a cash flow hedge.

Debt instruments that do not meet the conditions in FRS 102 paragraph 11.9 are subsequently measured at fair value through profit or loss. Debt instruments may be designated as being measured at fair value through profit or loss to eliminate or reduce an accounting mismatch or if the instruments are measured and their performance evaluated on a fair value basis in accordance with a documented risk management or investment strategy.

Financial liabilities are derecognised when the company’s contractual obligations expire or are discharged or cancelled.

The company uses forward foreign currency contracts to reduce exposure to foreign exchange rates.

Derivatives are initially recognised at fair value on the date a derivative contract is entered into and are subsequently re-measured at their fair value. Changes in fair value of derivatives are recognised in the income statement in finance costs or income as appropriate.

The company does not currently apply hedge accounting for foreign exchange derivatives.

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

The carrying amount of deferred tax assets is reviewed at each reporting end date and reduced to the extent that it is no longer probable that sufficient taxable profits will be available to allow all or part of the asset to be recovered. Deferred tax is calculated at the tax rates that are expected to apply in the period when the liability is settled or the asset is realised. Deferred tax is charged or credited in the income statement, 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.

Monetary assets and liabilities denominated in foreign currencies are translated into sterling at rates of exchange ruling at the statement of financial position date.

Transactions in foreign currencies are translated into sterling at the rate of exchange ruling at the date of transaction. Exchange differences are taken into account in arriving at the operating result.

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 where the revision affects only that period, or in the period of the revision and future periods where the revision affects both current and future periods.

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

Assessing the requirement for impairment of the carrying value of the investment in subsidiary undertakings is considered a key judgement in preparing the financial statements.

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

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