Allowances are available in respect of expenditure on plant and machinery if a person who is carrying on a qualifying activity (see ¶155-000) incurs qualifying expenditure (see ¶160-000). If a person carries on more than one qualifying activity, then allowances must be calculated separately for each.

The treatment of around 100 commonly-found items is addressed in the ‘The Plant and Machinery Index’.
