The engagement
A private healthcare operator bought its freehold trading premises for £725,000. Their accountants had treated the purchase entirely as property. We were instructed to establish what part of the price was, in substance, embedded plant and machinery.
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
- £62,400
- Special rate pool
- £126,900
- Total qualifying plant & machinery
- £189,300
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.
