FOR THE FINANCIAL YEAR ENDED 30 SEPTEMBER 2025
21ST CENTURY ENERGY LIMITED

## NOTES TO THE FINANCIAL STATEMENTS

FOR THE FINANCIAL YEAR ENDED 30 SEPTEMBER 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 year, unless otherwise stated.

##### General information and basis of accounting

21st Century Energy Limited (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 10 Lower Thames Street, London, EC3R 6AF, 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 have a reasonable expectation that the Company has adequate resources to continue in operational existence and to meet its financial obligations as they fall due 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.

##### Turnover

Turnover represents income from the generation of renewable electricity from the operational installations during the year, excluding Value Added Tax. Turnover is recognised in the period in which the electricity is generated.
Turnover is generated through the sale of electricity through the UK Government's Feed-in-Tariff (FiT) scheme.

##### Finance costs

Finance costs are charged to the Profit and Loss Account over the term of the debt using the effective interest method so the amount charged is at a constant rate on the carrying amount. Issue costs are initially recognised as a reduction in the proceeds of the associated capital instrument.

##### 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.
Deferred tax
Deferred tax arises as a result of including items of income and expenditure in taxation computations in periods different from those in which they are included in the Company's financial statements. Deferred tax is provided in full on timing differences which result in an obligation to pay more or less tax at a future date, at the average tax rates that are expected to apply when the timing differences reverse, based on current tax rates and laws. Deferred tax assets and liabilities are not discounted.
The carrying amount of deferred tax assets are reviewed at each reporting date and a valuation allowance is set up against deferred tax assets so that the net carrying amount equals the highest amount that is more likely than not to be recovered based on current or future taxable profit.

##### Tangible fixed assets

Tangible fixed assets are stated at cost net of depreciation and any provision for impairment. Depreciation commences on the date that the asset is brought into use. Historical cost includes expenditure that is directly attributable to bringing the asset to the location and condition necessary for it to be capable of operating in the manner intended by management. Depreciation is charged so as to allocate the cost of assets less their residual value over their estimated useful lives, using the straight-line method.

Plant and machinery etc. | 25 years straight line

Residual value represents the estimated amount which would currently be obtained from disposal of an asset, after deducting estimated costs of disposal, if the asset were already of the age and in the condition expected at the end of its useful life.
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.

##### Impairment of assets

Assets 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 is represented by deposits with financial intuitions repayable without penalty on notice of more than 24 hours, Cash equivalents are highly liquid investments that mature in no more than three
months from the date of acquisition and that are readily convertible to known amounts of cash with insignificant risk of change in value.

##### 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 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.

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

##### Provisions

Provisions are recognised when an event has taken place that gives rise to a legal or constructive obligation, a transfer of economic benefits is probable and a reliable estimate can be made. Provisions are measured as the best estimate of the amount required to settle the obligation, taking into account the related risks and uncertainties. Increases in provisions are generally charged as an expense to the profit or loss.
