FOR THE FINANCIAL YEAR ENDED 31 DECEMBER 2025
ELECTRADX UK LTD

## NOTES TO THE FINANCIAL STATEMENTS

FOR THE FINANCIAL YEAR ENDED 31 DECEMBER 2025

##### 1. Accounting policies

The principal accounting policies are summarised below. They have all been applied consistently throughout the financial year and to the preceding financial period, unless otherwise stated.

##### General information and basis of accounting

Electradx UK Ltd (the Company) is a private company, limited by shares, incorporated in the United Kingdom under the Companies Act 2006 and is registered in England and Wales. The address of the Company's registered office is 48 Chancery Lane, London, WC2A 1JF, United Kingdom.
The financial statements have been prepared under the historical cost convention, and in accordance with Section 1A of Financial Reporting Standard 102 (FRS 102) ‘The Financial Reporting Standard applicable in the UK and Republic of Ireland’ issued by the Financial Reporting Council and the requirements of the Companies Act 2006 as applicable to companies subject to the small companies regime.
The financial statements are presented in pounds sterling which is the functional currency of the Company and rounded to the nearest £.

##### Going concern

The directors have assessed the Balance Sheet and likely future cash flows at the date of approving these financial statements. The directors note that the business has net liabilities of £6,839,185. The Company is supported through loans from the Parent Company. The directors have received assurances that the loan facilities will continue to be available for at least 12 months from the date of signing these financial statements and the Parent Company will continue to support the Company. After making enquiries, the directors believe that any foreseeable debts can be met for at least 12 months from the date of signing these financial statements. Accordingly, they continue to adopt the going concern basis in preparing the financial statements.

##### Foreign currency

Transactions in foreign currencies are recorded at the rate of exchange at the date of the transaction. Monetary assets and liabilities denominated in foreign currencies at the Balance Sheet date are reported at the rates of exchange prevailing at that date.
Exchange differences are recognised in the Profit and Loss Account in the period in which they arise except for exchange differences arising on gains or losses on non-monetary items which are recognised in the Statement of Comprehensive Income.

##### Employee benefits

Defined contribution schemes
The Company operates a defined contribution scheme. The amount charged to the Profit and Loss Account in respect of pension costs and other post-retirement benefits is the contributions payable in the financial year. Differences between contributions payable in the financial year and contributions actually paid are included as either accruals or prepayments in the Balance Sheet.

##### Taxation

Current tax
Current tax is provided at amounts expected to be paid (or recoverable) using the tax rates and laws that have been enacted or substantively enacted at the Balance Sheet date.

##### Tangible fixed assets

Tangible fixed assets are stated at cost or valuation, net of depreciation and any provision for impairment. Depreciation is provided on all tangible fixed assets, at rates calculated to write off the cost or valuation of each asset on a straight-line or reducing balance basis over its expected useful life, as follows:

Leasehold improvements | 4 years straight line
Plant and machinery | 4 years straight line
Office equipment | 4 years straight line
Computer equipment | 4 years straight line

##### Leases

The Company as lessee
Assets held under finance leases, hire purchase contracts and other similar arrangements, which confer rights and obligations similar to those attached to owned assets, are capitalised as tangible fixed assets at the fair value of the leased asset (or, if lower, the present value of the minimum lease payments as determined at the inception of the lease) and are depreciated over the shorter of the lease terms and their useful lives. The capital elements of future lease obligations are recorded as liabilities, while the interest elements are charged to the Profit and Loss Account over the period of the leases to produce a constant periodic rate of interest on the remaining balance of the liability.
Rentals under operating leases are charged on a straight-line basis over the lease term, even if the payments are not made on such a basis. Benefits received and receivable as an incentive to sign an operating lease are similarly spread on a straight-line basis over the lease term.

##### Impairment of assets

Assets, other than those measured at fair value, are assessed for indicators of impairment at each Balance Sheet date. If there is objective evidence of impairment, an impairment loss is recognised in the Profit and Loss Account.

##### Cash and cash equivalents

Cash and cash equivalents are basic financial assets and include cash in hand.

##### Financial instruments

Financial assets and financial liabilities are recognised when the Company becomes a party to the contractual provisions of the instrument.
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.
Financial assets and liabilities are only offset in the Balance Sheet when, and only when there exists a legally enforceable right to set off the recognised amounts and the Company intends either to settle on a net basis, or to realise the asset and settle the liability simultaneously.

Basic financial assets
Basic financial assets, which include debtors and cash and bank balances, are measured at transaction price including transaction costs. Financial assets classified as receivable within one year are not amortised.

Financial assets are derecognised when and only when the contractual rights to the cash flows from the financial asset expire or are settled, or the Company transfers to another party substantially all of the risks and rewards of ownership of the financial asset, or the Company, despite having retained some, but not all, significant risks and rewards of ownership, has transferred control of the asset to another party.

Basic financial liabilities
Basic financial liabilities, including creditors and loans from fellow group companies are 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.
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.

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

Equity instruments
Equity instruments issued by the Company are recorded at the fair value of cash or other resources received or receivable, net of direct issue costs. If payment is deferred and the time value of money is material, the initial measurement is on a present value basis.
