Notes to the Financial Statements

Year ended 31 March 2026

1. General information

The company is a private company limited by shares, registered in England and Wales. The address of the registered office is 3 Rivergate, 1st Floor Temple Quay, Bristol, BS1 6EW. The company registration number is 03711047 .

2. Statement of compliance

The financial statements have been prepared in accordance with FRS 102 Section 1A - The Financial Reporting Standard applicable in the UK and Republic of Ireland (2024) and the Companies Act 2006. The company has early adopted the Amendments to FRS 102 The Financial Reporting Standard applicable in the UK and Republic of Ireland and other FRSs Periodic Review 2024 (FRS 102 periodic review amendments 2024) contained within FRS 102 (2024) which, if not early adopted, are applicable for periods beginning on or after 1 January 2026.

3. Accounting policies

Basis of preparation

The financial statements have been prepared on the historical cost basis. 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 £.

Changes in accounting policies

The company has adopted FRS 102 periodic review amendments 2024 with effect from 1 April 2025 with the amendments being applied retrospectively subject to exceptions set out in the standard. In accordance with the transitional provisions of the standard, comparatives have not been restated. The accounting policies for Leases and Revenue Recognition have been impacted as a result of the adoption of FRS 102 (2024). See Leases and Revenue Recognition accounting policies to understand the revised accounting policies.

Judgements and key sources of estimation uncertainty

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: As described in the accounting policies of the financial statements, depreciation of tangible fixed assets and amortisation of intangible assets has been based on estimated useful lives and residual values deemed appropriate by the directors. Estimated useful lives are reviewed annually and revised as appropriate. Revisions take in to account actual asset lives and residual values as evidenced by disposals during current and prior accounting periods.

Revenue recognition

Turnover comprises the value of sales (exclusive of VAT and discounts) of services provided in the normal course of business. Revenue is recognised in accordance with the five-step model (FRS 102 Section 23, 2024 Amendments) when the company satisfies a performance obligation by transferring control of a promised service to a customer. There is a material financial impact on the revenue of the company resulting from the application of the revised revenue accounting policy on the early adoption of the FRS 102 periodic review amendments 2024. There are now two performance obligations within contracts with customers and revenue is recognised as 50% of the contract value when each one is met.

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 material 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.

Foreign currencies

Monetary assets and liabilities denominated in foreign currencies are translated into sterling at the rates of exchange ruling at the balance sheet date. Group transactions in foreign currencies are recorded at a standard company rate. Other non group transactions are translated at the spot rate of the invoice date. All differences are taken to profit and loss account.

Amortisation

Amortisation is calculated so as to write off the cost of an asset, less its estimated residual value, over the useful life of that asset as follows:

	Development projects	-	Straight line over 5 - 7 years

If there is an indication that there has been a significant change in amortisation rate, useful life or residual value of an intangible asset, the amortisation is revised prospectively to reflect the new estimates.

Research and development

Research expenditure is written off in the period in which it is incurred. Development expenditure incurred is capitalised as an intangible asset only when all of the following criteria are met: - It is technically feasible to complete the intangible asset so that it will be available for use or sale; - There is the intention to complete the intangible asset and use or sell it; - There is the ability to use or sell the intangible asset; - The use or sale of the intangible asset will generate probable future economic benefits; - There are adequate technical, financial and other resources available to complete the development and to use or sell the intangible asset; and - The expenditure attributable to the intangible asset during its development can be measured reliably. Expenditure that does not meet the above criteria is expensed as incurred.

Tangible assets

Tangible assets are initially recorded at cost, and subsequently stated at cost less any accumulated depreciation and impairment losses. Right of use assets held under leases are depreciated in the same way as owned assets.

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:

Right of use asset	-	10% straight line
Land and buildings	-	10% straight line
Plant and machinery	-	33% straight line
Fixtures and fittings	-	25% - 33% straight line
Equipment	-	33% 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. For the purposes of impairment testing, when it is not possible to estimate the recoverable amount of an individual asset, an estimate is made of the recoverable amount of the cash-generating unit to which the asset belongs. The cash-generating unit is the smallest identifiable group of assets that includes the asset and generates cash inflows that largely independent of the cash inflows from other assets or groups of assets.

Stock and work in progress

Stock and work in progress have been valued at the lower of cost and estimated selling price less costs to sell. In respect of work in progress, cost includes a relevant proportion of overheads according to the stage of completion.

Leases

The revised FRS 102 Section 20 Leases changes how the company recognises leases which were previously classified as operating leases. With the exception of short-term leases and leases for low-value assets, the company now recognises right-of-use assets and lease liabilities on the balance sheet, initially measured at the present value of the future lease payments. The depreciation of the right-of-use asset and interest charges on the outstanding lease liability replace the straight-line rental expense previously booked to operating costs. Right-of-use assets will be tested for impairment in accordance with Section 27 Impairment of Assets. This replaces the previous requirement to recognise a provision for onerous lease contracts. The company is not a party to any leases where it acts as a lessor, but it does contract as a lessee for office buildings. At the inception of the contract, the company assesses whether a contract is, or contains, a lease. It recognises a right-of-use asset and a corresponding lease liability with respect to all lease arrangements in which it is the lessee, except for those which are short-term or low-value leases as explained below. The right-of-use assets and the lease liabilities are presented as separate line items in the Balance Sheet. The lease liability is initially measured at the present value of the lease payments that are not paid at the commencement date, discounted using the rate implicit in the lease. If this rate cannot be readily determined, the company uses its incremental or obtainable borrowing rate. The lease liability is subsequently measured by increasing the carrying amount to reflect interest in the lease liability (using the effective interest method) and by reducing the carrying amount to reflect the lease payments made. The company takes advantage of the practical expedients available in respect of leases of low- value items and short-term leases. This means that short-term leases less than 12 months and low-value asset leases are not recognised as lease liabilities and right -of -use asset but are recognised as an expense on a straight-line basis over the lease term. Low-value assets are any assets below the cost of £10,000 but excluding all cars, vans, lorries, land and buildings and production line equipment. The expenses are recognised within administrative expenses. The right-of-use asset is initially measured at an amount equal to the corresponding lease liability, plus lease payments made on or before the commencement day, less any lease incentives received and plus any initial direct costs. The right-of-use asset is subsequently measured at cost less accumulated depreciation and impairment losses. Depreciation on the right-of-use asset is recognised using the straight-line basis and starts at the commencement date of the lease. At each balance sheet date, the company reviews the carrying amount of its right-of-use assets to determine whether there is any indication that any items have suffered an impairment loss. If any such indication exists, the recoverable amount of an asset is estimated in order to determine the extent of the impairment loss, if any. Where it is not possible to estimate the recoverable amount of the asset, the company estimates the recoverable amount of the cash-generating unit to which the asset belongs.

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 balance sheet 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

Financial instruments are classified and accounted for, according to the substance of the contractual arrangement, as either financial assets, financial liabilities or equity instruments. An equity instrument is any contract that evidences a residual interest in the assets of the company after deducting all of its liabilities. The basic financial instruments of the company are as follows: Debtors Debtors do not carry any interest and are stated at their nominal value. Appropriate allowances for estimated irrecoverable amounts are recognised in the Profit and Loss account when there is objective evidence that the asset is impaired. Cash at bank and in hand This comprises cash at bank and cash in hand. Trade creditors Trade creditors are not interest bearing and are stated at their nominal value.

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.

The average number of persons employed by the company during the year amounted to 57 (2025: 47 ).
