London Electricity plc

Corporation tax - capital allowance - substation not 'plant'

Distinguishing equipment and construction

Expenditure incurred by London Electricity plc on the structure of an underground substation in Leicester Square for transforming electricity did not qualify for allowances under section 24 of the Capital Allowances Act 1990, previously section 44 of the Finance Act 1971.

A distinction had to be made between the expenditure on the earthing system and equipment installed within the structure, that qualified for the allowances, and that incurred on the construction of the substation itself that formed the premises from which the trade was carried on and thus did not qualify.

It then passed out of the substation by means of 11,000 volt cables to join the network serving central London.

The appeal raised again the question whether a building or structure was plant for the purposes of the legislation relating to capital allowances. The expenditure disallowed by the Crown was that on works preparatory to the construction of the substation, including the excavation of the site, and that on the construction of the substation.

London Electricity's primary contention, accepted by the commissioner, was that the whole of the substation, that is, the structure and the equipment within, was a single functioning entity and as such was a single unit of plant for capital allowances purposes.

The Crown, while accepting that the structure and the equipment housed within it were designed together, contended that the structure of the substation should be viewed as a single structure or building, separate...
