NOTES TO THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 31 JULY 2026

1.Accounting policies

 
1.1

Basis of preparation of financial statements

The financial statements have been prepared under the historical cost convention unless otherwise specified within these accounting policies and in accordance with Financial Reporting Standard 102, the Financial Reporting Standard applicable in the UK and the Republic of Ireland and the Companies Act 2006. The disclosure requirements of Section 1A of FRS 102 have been applied other than where additional disclosure is required to show a true and fair view.

The following principal accounting policies have been applied:

 
1.2

Foreign currency translation

Functional and presentation currency

The Company's functional and presentational currency is GBP.

Transactions and balances

Foreign currency transactions are translated into the functional currency using the spot exchange rates at the dates of the transactions.

At each period end foreign currency monetary items are translated using the closing rate. Non-monetary items measured at historical cost are translated using the exchange rate at the date of the transaction and non-monetary items measured at fair value are measured using the exchange rate when fair value was determined.

Foreign exchange gains and losses resulting from the settlement of transactions and from the translation at period-end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognised in profit or loss except when deferred in other comprehensive income as qualifying cash flow hedges.

Foreign exchange gains and losses that relate to borrowings and cash and cash equivalents are presented in the Statement of income and retained earnings within 'finance income or costs'. All other foreign exchange gains and losses are presented in profit or loss within 'other operating income'.

 
1.3

Revenue

Revenue is recognised to the extent that it is probable that the economic benefits will flow to the Company and the revenue can be reliably measured. Revenue is measured as the fair value of the consideration received or receivable, excluding discounts, rebates, value added tax and other sales taxes. The following criteria must also be met before revenue is recognised:

Rendering of services

Revenue from a contract to provide services is recognised in the period in which the services are provided in accordance with the stage of completion of the contract when all of the following conditions are satisfied:
∙the amount of revenue can be measured reliably;
∙it is probable that the Company will receive the consideration due under the contract;
∙the stage of completion of the contract at the end of the reporting period can be measured reliably; and
∙the costs incurred and the costs to complete the contract can be measured reliably.

NOTES TO THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 31 JULY 2026

1.Accounting policies (continued)

 
1.4

Government grants

Grants are accounted under the accruals model as permitted by FRS 102. Grants relating to expenditure on tangible fixed assets are credited to profit or loss at the same rate as the depreciation on the assets to which the grant relates. The deferred element of grants is included in creditors as deferred income.

Grants of a revenue nature are recognised in the Statement of income and retained earnings in the same period as the related expenditure.

 
1.5

Interest income

Interest income is recognised in profit or loss using the effective interest method.

 
1.6

Finance costs

Finance costs are charged to profit or loss over the term of the debt using the effective interest method so that 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.

 
1.7

Pensions

Defined contribution pension plan

The Company operates a defined contribution plan for its employees. A defined contribution plan is a pension plan under which the Company pays fixed contributions into a separate entity. Once the contributions have been paid the Company has no further payment obligations.

The contributions are recognised as an expense in profit or loss when they fall due. Amounts not paid are shown in accruals as a liability in the Statement of financial position. The assets of the plan are held separately from the Company in independently administered funds.

NOTES TO THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 31 JULY 2026

1.Accounting policies (continued)

 
1.8

Current and deferred taxation

The tax expense for the year comprises current and deferred tax. Tax is recognised in profit or loss except that a charge attributable to an item of income and expense recognised as other comprehensive income or to an item recognised directly in equity is also recognised in other comprehensive income or directly in equity respectively.

The current income tax charge is calculated on the basis of tax rates and laws that have been enacted or substantively enacted by the reporting date in the countries where the Company operates and generates income.

Deferred tax balances are recognised in respect of all timing differences that have originated but not reversed by the reporting date, except that:
∙The recognition of deferred tax assets is limited to the extent that it is probable that they will be recovered against the reversal of deferred tax liabilities or other future taxable profits; and
∙Any deferred tax balances are reversed if and when all conditions for retaining associated tax allowances have been met.

Deferred tax balances are not recognised in respect of permanent differences except in respect of business combinations, when deferred tax is recognised on the differences between the fair values of assets acquired and the future tax deductions available for them and the differences between the fair values of liabilities acquired and the amount that will be assessed for tax. Deferred tax is determined using tax rates and laws that have been enacted or substantively enacted by the reporting date.


 
1.9

Intangible assets

Intangible assets are initially recognised at cost. After recognition, under the cost model, intangible assets are measured at cost less any accumulated amortisation and any accumulated impairment losses.

All intangible assets are considered to have a finite useful life. If a reliable estimate of the useful life cannot be made, the useful life shall not exceed ten years.

 
1.10

Tangible fixed assets

Tangible fixed assets under the cost model are stated at historical cost less accumulated depreciation and any accumulated impairment losses. 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.

NOTES TO THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 31 JULY 2026

1.Accounting policies (continued)


1.10
Tangible fixed assets (continued)

Depreciation is charged so as to allocate the cost of assets less their residual value over their estimated useful lives, using the methods below.

Depreciation is provided on the following basis:

Plant and machinery
-
25%
reducing balance
Fixtures and fittings
-
25%
reducing balance
Office equipment
-
33%
straight line

The assets' residual values, useful lives and depreciation methods are reviewed, and adjusted prospectively if appropriate, or if there is an indication of a significant change since the last reporting date.

Gains and losses on disposals are determined by comparing the proceeds with the carrying amount and are recognised in profit or loss.

 
1.11

Debtors

Short-term debtors are measured at transaction price, less any impairment. Loans receivable are measured initially at fair value, net of transaction costs, and are measured subsequently at amortised cost using the effective interest method, less any impairment.

 
1.12

Cash and cash equivalents

Cash is represented by cash in hand and deposits with financial institutions repayable without penalty on notice of not 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.

 
1.13

Creditors

Short-term creditors are measured at the transaction price. Other financial liabilities, including bank loans, are measured initially at fair value, net of transaction costs, and are measured subsequently at amortised cost using the effective interest method.

 
1.14

Provisions for liabilities

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 profit or loss.

Reserves

Share application money pending allotment

At 31st July 2026 the company had received £1,393,658.58.  The money is held on account pending the allotment of shares.  The money is non-refundable and the company is obliged to issue the shares.

Also included in other reserves is the share based payment reserve which totalled £133,865 at 31st July 2026.


11.


Share-based payments









During the year the Company operated an equity-settled share option scheme for certain employees. Options are subject to continued employment and vest over 3-4 years. The options have a contractual life of 10 years and are settled by the issue of shares in the Company.

The fair value of options granted during the year was determined using the Black-Scholes option pricing model.

The share-based payment expense recognised in profit or loss for the year was £53,298 (2025: £38,417), with a corresponding credit recognised in equity.


12.


Prior year adjustment

During the year, the Company identified that the accounting for share-based payment arrangements in respect of the year ended 31st July 2025 and 31st July 2024 had not been recognised in the financial statements.

The correction has resulted in an increase in administrative expenses and a corresponding increase in the share-based payment reserve of £38,417 in respect of the year ended 31st July 2025 and £42,150 in respect of the year ended 31st July 2024. The comparative figures have been restated accordingly.


13.


Pension commitments

The Company operates a defined contributions pension scheme. The assets of the scheme are held separately from those of the Company  in an independently administered fund. The pension cost charge represents contributions payable by the Company to the fund and amounted to £10,790 (2025 - £7,573). Contributions totalling £50 (2025 - £50) were payable to the fund at the reporting date and are included in creditors.
