For the purposes of this chapter, ’repair' means the
restoration of an asset by replacing subsidiary parts of the whole.
No significant improvement of the asset beyond its original
condition can result or there will no longer be a repair.
The cost of a repair is normally revenue expenditure but the cost of replacing the asset or of making a significant improvement to the asset as a whole will be capital expenditure ( BIM46903).
The cost of a repair may be capital expenditure and not allowable as a deduction where the asset has just been acquired, see BIM46906 for further information.
It is worth taking care with the terms used; some people, for example, use ’renewal' to mean either a complete replacement of an ’entirety' or a replacement of, or repair to, an ’entirety'.
Sometimes more than one basis for relief may be available for expenditure; for example, machinery and plant capital allowances and the renewals basis. The general principle is that relief is only due once for expenditure on an asset.
