Bloom BESS Holdco Limited has elected to apply the presentation requirements of IAS 1 as it is deemed to provide more relevant information to the users of the financial statements.

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 and have been consistently applied to the years presented, unless otherwise stated.

The directors have at the time of approving the financial statements, a reasonable expectation that the truecompany has adequate resources to continue in operational existence for the foreseeable future. Thus the directors continue to adopt the going concern basis of accounting in preparing the financial statements.

Investments in subsidiaries 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.

General and specific borrowing costs directly attributable to the acquisition, construction or production of qualifying assets, which are assets that necessarily take a substantial period of time to get ready for their intended use, are added to the cost of those assets, until such time as the assets are substantially ready for their intended use. All other borrowing costs are recognised in profit or loss in the period in which they are incurred.

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.

Other financial assets

Other financial assets, including trade and other receivables are recognised initially at fair value. They are subsequently measured at amortised cost using the effective interest method.

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'.

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.

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

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.

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.

Management is required to assess the Group’s assets for indicators of impairment. Management takes into account external, internal and other potential indicators of impairment, and applies judgement in assessing whether any indicators exist.

The average number of persons employed by the Company during the financial year amounted to nil. The directors are not employed by the Company and did not receive any remuneration from the Company during the year.
