To qualify for a VAT431C reclaim, the building must have been wholly non-residential before conversion, planning permission must have been granted for the change of use, and the converted property must become your main or only home. Buildings used as homes before conversion, commercial properties with a residential annexe, and garages or outbuildings that are part of an existing home generally do not qualify.
Around 30% of conversion VAT reclaim enquiries involve properties where eligibility is uncertain — a mixed-use building, a partial conversion, or a property that had some residential use. Getting this wrong wastes months of preparation and leaves you with a rejected claim.
Barns, agricultural buildings, commercial offices, public houses, chapels, schools, and other buildings that have never been used as a home qualify under Notice 708 Section 7.
A building that was previously residential but has been empty for 10 or more years can also qualify for VAT431C — this is sometimes called the 'long-empty' route.
If a commercial building also contained residential accommodation (a pub with a landlord's flat, a farmhouse with a barn attached), only the non-residential part qualifies — if conversion involves the residential element, eligibility is restricted.
Converting or extending an existing residential dwelling does not qualify for VAT431C. That work is subject to standard-rate VAT and is not reclaimable under the DIY scheme.

VATBuild's project setup asks the key eligibility questions up front — building type, previous use, planning status and occupancy intention. Based on your answers, it identifies which HMRC VAT scheme applies to your project before you upload a single invoice, so you know you are working towards a valid claim.
