Reclaiming VAT on a self-build home project

Reclaiming VAT on a self-build home project can significantly reduce the overall cost of building or converting your property. The VAT DIY Housebuilders Scheme is a special VAT scheme that allows private individuals to benefit from the same VAT advantages as professional property developers. Under this scheme, the qualifying construction costs of a new home and certain types of conversion work can effectively benefit from VAT zero-rating. This allows qualifying homeowners to reclaim the VAT paid on eligible building materials.

A claim can be made for qualifying building materials on which VAT has been charged. Qualifying materials include most materials incorporated into a new building or conversion which cannot easily be removed. This includes items such as bricks, timber, roofing materials, plumbing, wiring and plaster. Items such as fitted furniture, carpets, curtains, and certain domestic appliances are excluded from the scheme, even if they are installed as part of the build.

In most cases, you must submit a claim within six months of completing the new build or conversion project. Completion is usually evidenced by a completion certificate or similar official documentation.

Claims are normally submitted online. However, if you are unable to use the digital service, you can apply using paper forms. There are two main forms available: VAT 431NB for new build properties, and VAT 431C for qualifying conversions.
