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. The address of the registered office is Indoor Environmental Systems Limited, Unit 15, The Courtyard, Gorsey Lane, Coleshill.

2. Statement of compliance

These financial statements have been prepared in compliance with the provisions of FRS 102, Section 1A, 'The Financial Reporting Standard applicable in the UK and 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.

Turnover

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.

Taxation

The taxation expense represents the aggregate amount of current and deferred tax recognised in the reporting period. Tax is recognised in the statement of comprehensive income, except to the extent that it relates to items recognised in other comprehensive income or directly in capital and reserves. In this case, tax is recognised in other comprehensive income or directly in capital and reserves, 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 are 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:


Fittings fixtures and equipment	-	20 %	straight line
Motor vehicles	-	25 %	straight line

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

Impairment

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.

Financial instruments

A financial asset or a financial liability is recognised only when the company becomes a party to the contractual provisions of the instrument. Basic financial instruments are initially recognised at the transaction price, unless the arrangement constitutes a financing transaction, where it is recognised at the present value of the future payments discounted at a market rate of interest for a similar debt instrument. Other financial instruments are subsequently measured at fair value, with any changes recognised in profit or loss, with the exception of hedging instruments in a designated hedging relationship.

Financial assets that are measured at cost or amortised cost are reviewed for objective evidence of impairment at the end of each reporting date. If there is objective evidence of impairment, an impairment loss is recognised in profit or loss immediately.

For all equity instruments regardless of significance, and other financial assets that are individually significant, these are assessed individually for impairment. Other financial assets or either assessed individually or grouped on the basis of similar credit risk characteristics.

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.

4. Employee numbers

The average number of persons employed by the company during the year amounted to 3 (2025: 1 ).
