The engagement
Our client bought a freehold 240 m² high-street unit for £320,000 to trade from. The purchase had been treated entirely as property; we were instructed to establish the embedded plant within the price.
Our approach
- Desktop analysis plus a single site survey
- Reconstruction costs from BCIS (RICS) and Spon's data; land value to VOA benchmarks
- Apportioned to HMRC's formula under CAA 2001 s.562
- Filing-ready report with statutory basis and pool allocation
The result
- Main rate pool
- £30,920
- Special rate pool
- £50,455
- Total qualifying plant & machinery
- £81,375
HMRC's apportionment formula
Q = P × A ÷ (B + C)
Q qualifying expenditure · P purchase expenditure · A reconstruction value of plant · B reconstruction value of building · C bare site value.
