Specified building works to adapt a dwelling for the use of a disabled person are zero-rated for VAT under VATA 1994 Schedule 8 Group 12. The zero-rate applies to the contractor's supply of the qualifying works — including labour and materials in a supply-and-fix contract. To qualify, the disabled person must be the recipient of the supply, the works must be carried out in their sole or principal private residence, and the specific works must fall within the statutory list of qualifying adaptations. The list is defined by statute, not by general description.
A qualifying disability adaptation can be zero-rated in full — no VAT at all on the contractor's supply. On a £30,000 adaptation project, that is £6,000. Most contractors are unfamiliar with the conditions and will default to 20%. You need to identify qualifying works and brief your contractor before contracting.
Extensions to provide facilities specifically for a disabled person (e.g., a ground-floor bathroom), ramps in place of steps, wider doors and passages, and installation of stairlifts, hoists, and similar equipment are in the statutory qualifying list.
Materials incorporated into a qualifying zero-rated adaptation supply take the same zero rate as the supply as a whole — the contractor does not need to apportion labour and materials.
Works that improve the general condition of the property but are not specifically for the disabled person's use are standard-rated at 20%. The zero-rate is narrow — it applies to adaptation works, not to renovation works that happen to benefit a disabled occupant.
The contractor is required to hold a declaration from the disabled person confirming they occupy (or intend to occupy) the property as their sole or principal residence. Without this declaration, the contractor should not apply the zero rate.

VATBuild identifies line items on your invoices that correspond to disability adaptations listed in the statutory zero-rating schedule and checks whether the correct 0% rate has been applied. It flags any qualifying adaptation line charged at 20% and generates a correction report for those invoices.
