The person incurring the expenditure must generally own the plant or machinery as a result of incurring it.

Neither plant nor machinery are defined in the legislation and so take their ordinary meaning.

See B3.306.

For the way in which allowances are given and charges are made, see B3.106 (capital allowances generally) and B3.380 (plant and machinery allowances).
