Self BuildersRenovations VAT
There is no VAT reclaim scheme for homeowners renovating an existing property. But there are specific VAT reliefs — energy saving materials at 0%, empty-property renovation at 5%, disability adaptations at 0% — that must be secured at the point of contracting. Once you have paid a 20% invoice that should have been lower, recovering the difference requires a contractor correction. VATBuild finds these opportunities before they are lost.
The DIY Housebuilders Scheme (VAT431NB and VAT431C) only covers new builds and qualifying non-residential conversions. Ordinary renovation of an existing home is not covered. VAT reliefs that do apply — energy saving materials, empty property, disability — are applied at the point of invoicing. If your contractor charges 20% on a line that should be 0% or 5%, your only recourse is to ask them to correct it.
VAT rate reliefs on renovation are applied at the point of invoicing. Once the invoice is issued and paid at 20%, recovering the overpaid VAT requires the contractor to issue a credit note, reissue the invoice at the correct rate, and adjust their own VAT return — and then refund you the difference. This becomes exponentially harder once a project finishes and the contractor has moved on.
ESM 0% rate must be applied on the original invoice — HMRC does not issue a refund for ESM overpayments.
Contractors who have already filed a VAT return at 20% need to submit an amendment — many are reluctant to do this retrospectively.
Empty-property evidence must be provided before the contractor applies 5% — gathering it after completion does not unlock a retrospective rate change.
Disability adaptation declarations must be provided before the supply is made — they cannot be backdated.
Each card links to a detailed answer covering the HMRC rules, the distinction that matters, and what to do next.
There is no general reclaim scheme for renovation. But specific reliefs may apply — find out what they are.
It depends. ESM, empty property, and disability adaptation works attract lower rates. 20% may be an overcharge.
HMRC says an extension that happens to include insulation is usually a single 20% supply. The 0% exception explained.
No. The 0% ESM rate requires supply-and-install by a contractor. Materials you buy separately are always 20%.
If empty for 2+ years, qualifying renovation works may be at 5% reduced rate. Evidence is required.
Works that reduce the number of dwellings in a building can qualify for 5% under Notice 708 Section 8.
Different elements attract different rates. A single invoice at one rate is usually wrong. The single-supply rule explained.
Each relief has its own qualifying conditions, evidence requirements, and rate. Select the area that applies to your project.
Qualifying ESM supply-and-install (insulation, heat pumps, solar, wind, water turbines) in a domestic building is currently zero-rated. From 1 April 2027 the rate reverts to 5%. This is applied at source — not a reclaim.
Qualifying renovation of a dwelling that has been empty for at least two consecutive years may be charged at the 5% reduced rate by the contractor. Evidence of the empty period is required before the contractor can apply the rate.
Works that reduce the number of separate dwellings in a building (e.g., converting two flats into one house) qualify for the 5% reduced rate on the contractor's services. Planning or building control evidence required.
Specified building adaptations for a disabled person in their principal residence can be zero-rated under VATA 1994 Schedule 8 Group 12. A declaration from the disabled occupant is required.
A project with ESM, empty-property, and general renovation elements can carry all three VAT rates on one invoice — if each element is separately identified and priced. A lump-sum quote at one rate is usually wrong.
VATBuild asks about your project type — ESM works, empty property status, dwelling-number changes, disability adaptations — and identifies which VAT reliefs may apply before you upload a single invoice.
Every invoice line is assessed against the applicable HMRC rate rule for that element. ESM lines, empty-property qualifying works, and general renovation lines are each rated separately.
Where a contractor has charged 20% on a line that qualifies for 0% or 5%, VATBuild flags it and generates a correction report identifying which invoices need to be reissued.
VATBuild detects single-line invoices that bundle different rate elements and prompts you to request a separately itemised invoice from the contractor before payment.
Every line item is documented with its VAT classification, the HMRC rule that applies, and a plain-English reason — a record you can show your contractor, accountant, or HMRC if questioned.
VATBuild is useful at every stage of a renovation.
Set up your project, identify qualifying VAT reliefs, and know what rate to expect on each element — before any contract is signed.
Check that contractor quotations separately price each rate element. VATBuild identifies where a bundled quote should be split.
Upload invoices as they arrive. VATBuild checks the rate on each line and flags any invoice that needs a correction before you pay.
If you have already paid invoices at the wrong rate, VATBuild identifies which ones and generates a correction report for each contractor.
Run a full VAT rate audit of all invoices after completion to confirm every element was correctly rated and identify any remaining disputes.
Generate a structured VAT summary for your accountant — each invoice line, the applicable rate, and whether the rate charged was correct.
Set up your renovation project, upload your invoices as they arrive, and VATBuild will tell you whether the rate on every line item is correct — and what to do if it is not.
