Turnover is measured at the fair value of the consideration received or receivable, net of discounts and value added taxes. Turnover includes revenue earned from the from the rendering of services.

Revenue from the rendering of services is recognised by reference to the stage of completion of the contract. The stage of completion of a contract is measured by comparing the costs incurred for work performed to date to the total estimated contract costs. Turnover is only recognised to the extent of recoverable expenses when the outcome of a contract cannot be estimated reliably.

Short-term employee benefits are measured at the undiscounted amount expected to be paid in exchange for the employee's services to the company. Where employees have accrued short-term benefits which the entity has not paid by the balance sheet date, an accrual is recognised within creditors: amounts falling due within one year together with an associated expense in profit or loss. The liabilities are classified as current obligations in the statement of financial position because they are expected to be settled wholly within twelve months after the end of the period.

Where, substantially, all the risks and rewards of ownership of the asset do not transfer from the lessor to the company, the lease is treated as an operating lease. Rentals payable under operating leases, including any lease incentives received, are charged to profit or loss on a straight line basis over the term of the relevant lease except where another more systematic basis is more representative of the time pattern in which economic benefits from the leased asset are consumed.

Finance costs charged to the profit or loss include interest expense calculated using the effective interest method from FRS 102:11, finance charges on finance leases, and exchange differences on foreign currency borrowings where these are treated as an adjustment to interest costs.

Current tax is recognised in profit or loss, except for taxes related to revaluations of land and buildings which are recognised in other comprehensive income.

Current tax represents the amount of tax payable (receivable) in respect of taxable profit (loss) for the current, or past, reporting periods. Current tax is measured at the amount expected to be paid (recovered) using the tax rates and laws which have been enacted, or substantively enacted, by the balance sheet date. Where payments to HM Revenue and Customs exceed liabilities owed, an asset is recognised to the extent of the amount of tax recoverable.

Inventories are measured at the lower of cost and estimated selling price less costs to complete and sell. Cost is determined using the first-in, first-out (FIFO) method. The cost of finished goods and work in progress comprises direct materials and, where applicable, direct labour costs and those overheads that have been incurred in bringing the inventories to their present location and condition. At each reporting date, inventories are assessed for impairment. If an item of inventory is impaired, the carrying amount is reduced to its selling price less costs to complete and sell, and the impairment loss is recognised immediately in the income statement. When inventories are sold, the carrying amount is recognised as an expense in the period in which the related revenue is recognised.

For long-term contracts where the company provides services or bespoke goods, work in progress is recognised as a contract asset. These are measured by reference to the stage of completion of the contract activity at the reporting date, based on the progress made towards the complete satisfaction of the performance obligations.

Short term creditors are measured at transaction price (which is usually the invoice price). Loans and other financial liabilities are initially recognised at transaction price net of any transaction costs and subsequently measured at amortised cost determined using the effective interest method.
