There are a small number of situations where reduced or zero rates can apply — long-empty homes, genuinely new self-contained dwellings, and certain works to listed buildings and places of worship — but the rules are narrow, specific, and easy to get wrong.
This page explains the categories in plain terms so you know what to ask about, but it is not a substitute for confirming your own position with HMRC or your accountant before work starts — VAT status can affect how a contractor invoices from the very first payment, so it needs settling early, not retrospectively.
The default position: standard rate
Renovations, extensions, loft conversions, kitchen and bathroom refits, and general repair and maintenance to an existing occupied home are standard-rated VAT. This applies whether the work is structural or cosmetic.
Budget on this basis unless you have good reason and written confirmation to expect otherwise — it's the outcome for the large majority of domestic projects we quote.
Genuinely new dwellings: zero-rated
Construction of a new, self-contained dwelling from scratch is generally zero-rated, including most of the labour and materials that go into it. This covers a self-build house on a plot, and in some cases the construction of an entirely new annexe that meets the strict tests for being a separate dwelling.
The dwelling must be genuinely self-contained — its own access, no internal connection to another dwelling, no restriction preventing separate sale or letting — and simply calling something 'an annexe' doesn't make it qualify if it fails those tests.
Empty homes: the two-year and ten-year rules
Renovating a property that has been empty for at least two years before work starts can qualify for the reduced 5% rate. If it has been empty for at least ten years, the works to bring it back into use can in some circumstances be zero-rated.
Evidence matters here — council tax records, empty homes officer confirmation, utility disconnection dates. HMRC will want proof of the empty period, not just your say-so, so gather this before work starts rather than trying to reconstruct it afterwards.
- Empty 2+ years before work starts: potential 5% reduced rate
- Empty 10+ years before work starts: potential zero rate on qualifying works
- Evidence of the empty period must be gathered in advance
Listed buildings and places of worship
The old zero rating for approved alterations to listed buildings was withdrawn some years ago, and most work to a listed home — repair, alteration, extension — is now standard-rated like any other property, which surprises a lot of owners who assume heritage status brings a VAT advantage. It generally doesn't.
Certain works to listed places of worship can still access separate grant schemes that effectively refund VAT, but that's a different mechanism to a reduced rate on the invoice, and it applies to the building type, not general domestic property.
Converting non-residential buildings
Converting a building that hasn't been used as a dwelling — a barn, an office, a shop with a flat above being fully converted — into residential use can qualify for the reduced 5% rate, and in some cases zero rating if it results in a genuinely new dwelling.
This is a common route for Wealden barn and oast conversions in this part of Kent, but the eligibility turns on the building's prior use and how many dwellings result, both of which need checking against HMRC's specific tests before quoting is finalised.
Why you must check with HMRC or your accountant first
VAT liability is a matter between you (or us, depending on how invoicing is structured), HMRC and the facts of the property — a contractor can advise on what category a project looks like it might fall into, but cannot guarantee a VAT rate, and getting it wrong has real financial consequences if HMRC later disagrees.
We'll flag where we think a reduced or zero rate might genuinely apply so you know to investigate it, but the responsibility for confirming eligibility and providing the necessary evidence sits with you and your adviser, not with us.
Common questions
Is VAT charged on all building work?
Most domestic renovation, extension and repair work is standard-rated. Reduced or zero rates only apply in specific circumstances — new dwellings, long-empty properties, and certain non-residential conversions — and each has its own qualifying tests.
How do I prove a house has been empty for VAT purposes?
Council tax records showing an empty property discount or exemption, confirmation from the council's empty homes team, and utility disconnection or non-use records are typically used as evidence. Gather this before work starts, as it's harder to reconstruct after the fact.
Do listed buildings get VAT relief on renovations?
Not generally any more. The relief for approved alterations to listed buildings was withdrawn years ago, so most listed building work is standard-rated in the same way as any other property, unless it falls into one of the separate categories such as a genuine conversion or empty-home rule.
Can a builder guarantee me a reduced VAT rate?
No, and be wary of anyone who does. Eligibility depends on facts about the property and its history that HMRC assesses, not something a contractor can promise. We can flag likely categories, but you and your accountant need to confirm the position.
When should I sort out VAT status — before or after getting quotes?
Before work starts and ideally before final quotes are issued, since it affects invoicing from the first payment. If a rate is later found not to apply, correcting it retrospectively is far more difficult than settling it up front.
