Notes to the Financial Statements

Period from 1 April 2025 to 31 December 2025
1. General information
The company is a private company limited by shares, registered in England and Wales. The address of the registered office is 5 Minton Place, Victoria Road, Bicester, Oxon, OX26 6QB. The address of the place of business of the company is Unit 5, Curtis Yard, North Hinksey Lane, Botley, Oxford, OX2 0LX.
2. Statement of compliance
These financial statements have been prepared in compliance with Section 1A of FRS 102, 'The Financial Reporting Standard applicable in the UK and the Republic of Ireland'.
3. Accounting policies
Basis of preparation
The financial statements have been prepared on the historical cost basis, as modified by the revaluation of certain financial assets and liabilities and investment properties measured at fair value through profit or loss. The financial statements are prepared in sterling, which is the functional currency of the entity. Monetary amounts in these financial statements are rounded to the nearest £.
Judgements and key sources of estimation uncertainty
The judgements (apart from those involving estimations) that management has made in the process of applying the entity's accounting policies and that have the most significant effect on the amounts recognised in the financial statements are as follows: Accounting estimates and assumptions are made concerning the future and, by their nature, will rarely equal the related actual outcome. The key assumptions and other sources of estimation uncertainty that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year are as follows: Depreciation: The useful lives of fixed assets are based on management's judgment and are reviewed annually to ensure they reflect the current economic reality of the asset usage. Bonus accrual: The majority of staff bonuses are discretionary and will be determined based on employee performance for the twelve months ending 31 March 2026. The accrual at 31 December 2025 must therefore be estimated.
Revenue recognition
Turnover is measured at the fair value of the consideration received or receivable for goods supplied and services rendered, net of discounts and Value Added Tax. Revenue from services rendered is recognised at the point of delivery. Revenue from the sale of goods is recognised when the significant risks and rewards of ownership have transferred to the buyer (usually on despatch of the goods); the amount of revenue can be measured reliably; it is probable that the associated economic benefits will flow to the entity; and the costs incurred or to be incurred in respect of the transactions can be measured reliably.
Income tax
The taxation expense represents the aggregate amount of current and deferred tax recognised in the reporting period. Tax is recognised in profit or loss, except to the extent that it relates to items recognised in other comprehensive income or directly in equity. In this case, tax is recognised in other comprehensive income or directly in equity, respectively. Current tax is recognised on taxable profit for the current and past periods. Current tax is measured at the amounts of tax expected to pay or recover using the tax rates and laws that have been enacted or substantively enacted at the reporting date.
Deferred tax is recognised in respect of all timing differences at the reporting date. Unrelieved tax losses and other 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. Deferred tax is measured using the tax rates and laws that have been enacted or substantively enacted by the reporting date that are expected to apply to the reversal of the timing difference.
Operating leases
Lease payments are recognised as an expense over the lease term on a straight-line basis. The aggregate benefit of lease incentives is recognised as a reduction to expense over the lease term, on a straight-line basis.
Tangible assets
Tangible assets are initially recorded at cost, and subsequently stated at cost less any accumulated depreciation and impairment losses.
Depreciation
Depreciation is calculated so as to write off the cost or valuation of an asset, less its residual value, over the useful economic life of that asset as follows:

| Plant and machinery | - | 10% straight line
| Fixtures and fittings | - | 10% straight line
| Motor vehicles | - | 25% straight line

Impairment of fixed assets
A review for indicators of impairment is carried out at each reporting date, with the recoverable amount being estimated where such indicators exist. Where the carrying value exceeds the recoverable amount, the asset is impaired accordingly. Prior impairments are also reviewed for possible reversal at each reporting date.
Stocks
Stocks are measured at the lower of cost and estimated selling price less costs to complete and sell. Cost includes all costs of purchase, costs of conversion and other costs incurred in bringing the stock to its present location and condition.
Provisions
Provisions are recognised when the entity has an obligation at the reporting date as a result of a past event, it is probable that the entity will be required to transfer economic benefits in settlement and the amount of the obligation can be estimated reliably. Provisions are recognised as a liability in the statement of financial position and the amount of the provision as an expense. Provisions are initially measured at the best estimate of the amount required to settle the obligation at the reporting date and subsequently reviewed at each reporting date and adjusted to reflect the current best estimate of the amount that would be required to settle the obligation. Any adjustments to the amounts previously recognised are recognised in profit or loss unless the provision was originally recognised as part of the cost of an asset. When a provision is measured at the present value of the amount expected to be required to settle the obligation, the unwinding of the discount is recognised as a finance cost in profit or loss in the period it arises.
Financial instruments
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 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. Classification of financial liabilities 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 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 ere 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. Trade creditors are obligations to pay for goods or services that have been acquired in the ordinary course of business from suppliers. Accounts payable are classified as current liabilities if the Company does not have an unconditional right, at the end of the reporting period, to defer settlement of the creditor for at least twelve months after the reporting date. If there is an unconditional right to defer settlement of the creditor for at least twelve months after the reporting date, they are presented as non-current liabilities. Trade creditors are recognised initially at the transaction price, unless the arrangement constitutes a financing transaction where the transaction is measured at amortised costs using the effective interest rate method.
Defined contribution plans
Contributions to defined contribution plans are recognised as an expense in the period in which the related service is provided. Prepaid contributions are recognised as an asset to the extent that the prepayment will lead to a reduction in future payments or a cash refund. When contributions are not expected to be settled wholly within 12 months of the end of the reporting date in which the employees render the related service, the liability is measured on a discounted present value basis. The unwinding of the discount is recognised as a finance cost in profit or loss in the period in which it arises.
4. Employee numbers
The average number of persons employed by the company during the period amounted to 45 (2025: 41 ).
