Plant & Machinery Allowances (PMA): Buildings & structures: Expenditure unaffected by legislation

CAA01/S23, FA08/S71(7), S72(1) & S73(1)(b)

This expenditure is not affected by the legislation saying that most buildings and structures are not plant.

Expenditure on:

  • thermal insulation of industrial buildings CA22220 
  • fire safety CA22230; incurred before 1 April 2008 (CT) and 6 April 2008 (IT)
  • safety at designated sports grounds CA22240 
  • safety at regulated stands at sports grounds CA22250 
  • safety at other sports grounds CA22260 
  • personal security CA22270 
  • integral features CA22300 incurred on or after 1 April 2008 (CT) and on or after 6 April 2008 (IT)
  • software and rights to software CA22280 
  • films for which an election is made ITTOIA/S143 or F2A92/40D (repealed by FA06/S178 and Schedule 26, part 3(4) with effect from 1 January 2007)

and expenditure on any item in the list below, list C. The list does not operate by analogy: for example item 33 which refers to fixed zoo cages does not apply to any other form of animal shelter such as kennels or stables. The legislation does not say that an item in the list below is plant. All it says is that an item in the list is not affected by the legislation (in preceding sections 21 and 22), saying that most buildings and structures are not plant. But an item in the list has to pass the normal plant tests before allowances are due.

Items 1 to 16 in the list below do not include any asset whose principal purpose is to insulate or enclose the interior of a building or to provide an interior wall, floor or ceiling which (in each case) is intended to remain permanently in place.

1 Machinery (including devices for providing motive power) not within any other item in this list
