Phoslock Water Solutions (UK) Limited is a private company limited by shares incorporated in England and Wales. The registered office is The Courtyard, Shoreham Road, Upper Beeding, Steyning, West Sussex, BN44 3TN.

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 as applicable to companies subject to the small companies regime. The disclosure requirements of section 1A of FRS 102 have been applied other than where additional disclosure is required to show a true and fair view.

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, modified to include the revaluation of freehold properties and to include investment properties and certain financial instruments at fair value. 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 4 ‘Statement of Financial Position’: Reconciliation of the opening and closing number of shares;

• 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’: Carrying amounts, interest income/expense and net gains/losses for each category of financial instrument; 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 26 ‘Share based Payment’: Share-based payment expense charged to profit or loss, reconciliation of opening and closing number and weighted average exercise price of share options, how the fair value of options granted was measured, measurement and carrying amount of liabilities for cash-settled share-based payments, explanation of modifications to arrangements;

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

The financial statements of the company are consolidated in the financial statements of Phoslock Environmental Technologies Limited. These consolidated financial statements are available from its registered office, Unit D, Level 2, Como Centre, 650 Chapel Street, South Yarra, VIC 3141.

The company incurred a loss of £162,691 during the year ended 31 December 2025 and, at that date, had net liabilities of £1,209,574. The company is dependent upon the continued financial support of its parent undertaking, Phoslock Environmental Technologies Limited, to meet its liabilities as they fall due. true

The directors have reviewed the company's projected cash flow requirements for a period of at least twelve months from the date of approval of these financial statements and have considered the financial position and future prospects of the wider Phoslock group. The ultimate parent undertaking reported cash and cash equivalents of A$5.2 million and net assets of A$6.8 million as at 31 December 2025 and has prepared its consolidated financial statements on a going concern basis. The parent group's directors have stated that they expect the group to maintain sufficient liquidity to support ongoing operations and meet its obligations as they fall due.

The directors have received confirmation from the parent undertaking that it will continue to provide financial support to the company for a period of at least twelve months from the date of approval of these financial statements and that it does not intend to demand repayment of amounts due to it where this would prejudice the company's ability to continue trading.

Accordingly, the directors have a reasonable expectation that the company has adequate resources to continue in operational existence for the foreseeable future and have therefore adopted the going concern basis in preparing these financial statements.

Turnover represents amounts receivable for the sale and promotion of water treatment products and the provision of associated technical support services within the United Kingdom and Europe, net of VAT and trade discounts.

Revenue from product sales is recognised when control of the goods passes to the customer. Revenue from technical support and consultancy services is recognised when the related services have been performed.

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

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

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

Cash and cash equivalents are basic financial assets and 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 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 balance sheet 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.

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 company after deducting all of its liabilities.

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

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

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

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

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

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

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

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

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