Indicative estimate using PTO standard rates + CAA 2001 s562. A chartered surveyor finalises the claim.

How much can you claim?

On most commercial property purchases, embedded fixtures and integral features — heating, electrical and water systems, lighting, sanitaryware, fire alarms and more — make up 20–40% of the purchase price. That’s often £25,000 to £175,000+ in claimable capital allowances that owners and their accountants routinely miss.

This calculator gives an indicative figure using Property Tax Optimisers’ standard rates and the CAA 2001 s562 apportionment. For a defensible, HMRC-compliant claim, CapexScan turns a quick property scan into a QS-grade report — reviewed and signed off by a chartered surveyor.
