Converting a Pub or Commercial Building to Residential — VAT Guide

Converting a former pub, restaurant, hotel, office or other commercial building into a residential home typically qualifies for the VAT431C DIY conversion scheme. Contractor building services should be charged at 5% VAT — not 20%. Materials you purchase directly are at 20%, and that 20% is fully reclaimable via VAT431C. The claim must be submitted within 6 months of your building control completion certificate.

£18,000–£40,000

Why this matters

Commercial-to-residential conversions are among the most complex VAT431C claims — mixed use history, existing services infrastructure, and planning conditions all create eligibility questions. A typical reclaimable VAT amount is £18,000–£40,000, but errors in the contractor rate or mixed-use exclusions can significantly reduce it.

The key distinctions

Eligible — wholly commercial building

A pub, restaurant, hotel, office or retail unit with no residential component qualifies under Notice 708 Section 7. The key test is that the building was wholly non-residential in its last use.

Complication — pub with living quarters

Many pubs had a landlord's flat or manager's accommodation. If the residential part was in active use, it may not qualify for VAT431C. The non-residential trading areas typically still qualify — the residential element needs separate assessment.

Correctly charged — 5% on contractor building services

Structural work, internal reconfiguration, roofing, glazing, plumbing, electrical, plastering and all building services forming part of the conversion should be charged at 5%.

Often overcharged — stripping out existing commercial fit-out

Strip-out works (removing bars, commercial kitchens, partitions) are part of the conversion. They should be at 5%. Some contractors incorrectly charge 20% on strip-out as 'demolition' — this is a rate error.

Practical checklist

  • Confirm the building's last use was wholly commercial — no active residential occupation
  • Obtain planning permission for change of use from commercial to residential
  • Check every contractor invoice shows 5% on building services, not 20%
  • If the building had a residential flat, assess whether that element qualifies separately
  • Include strip-out works in your claim — these are part of the conversion
  • Keep merchant receipts for all direct material purchases made throughout the project
  • Apply for your building control completion certificate promptly after works finish
  • Submit your VAT431C claim within 6 months of the completion certificate date
