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 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.

Revenue from the provision of services is recognised in the period in which the services are provided when all of the following conditions are satisfied; the amount of revenue can be measured reliably; it is probable that the economic benefits associated with the transaction will flow to the entity; the stage of completion of the transaction at the end of the reporting period can be measured reliably and the costs incurred and costs to complete the transaction can be measured reliably.

Deferred taxation is provided on the liability method to take account of timing differences between the treatment of certain items for accounts purposes and their treatment for tax purposes.

Tax deferred or accelerated is accounted for in respect of all material timing differences, in particular accelerated capital allowances and revaluation gains on investment properties. All deferred tax is charged/(credited) to the Income Statement.

The directors assess the company's tangible assets for evidence of impairment at each reporting date. Where there are indicators of impairment, the directors calculate recoverable amount of the asset(s) and compare this with the carrying amount. If the recoverable amount is lower than carrying amount, the asset is written down to recoverable amount by way of an impairment loss which is recognised in profit or loss for the period.

Impairment losses are reversed when there is evidence that the reasons giving rise to the original impairment have ceased to apply. Impairment losses are reversed through profit and loss but only to the extent that the reversal does not increase the carrying amount of the asset to the amount which would have been stated, net of depreciation, had no impairment loss been recognised.

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.
