VAT on Property Renovations: The 5% Reduced Rate for Empty Homes and Changes of Use

Most renovation and conversion work is standard-rated at 20% VAT by default. But three specific situations — renovating a long-empty home, changing the number of dwellings in a building, and converting non-residential space into housing — can bring that down to 5%, or in some cases to zero. The relief is worth real money on any refurbishment budget, and it is also one of the most commonly misapplied areas of construction VAT, because the conditions have to be met before work starts, not fixed up afterwards.

The default position: 20% unless a relief applies

Unlike constructing a brand new dwelling from scratch — which is usually zero-rated — renovating, altering or repairing an existing building is standard-rated construction work as far as VAT is concerned. That is true whether the work is a full gut-and-refit or routine maintenance. The reduced and zero rates covered here are specific reliefs that apply only where a defined set of conditions is met, and HMRC's starting assumption on any enquiry is that 20% applies unless the taxpayer can show otherwise.

Empty homes: the two-year rule

Renovating or altering a residential property qualifies for 5% VAT if the property has not been lived in for at least two years immediately before the work begins. The relief covers the contractor's services and any building materials they supply and fit as part of that work — it does not extend to materials bought separately by the property owner.

In practice, the two-year test is where most disputes arise. HMRC does not take the owner's word for it; they expect documentary evidence that the property was genuinely unoccupied, such as:

• Council tax records showing an empty property discount, premium, or exemption over the relevant period
• Electoral roll records showing no registered occupants
• Utility account statements showing minimal or no consumption
• Empty Homes Register or local authority correspondence, where available

Short periods of unauthorised occupation, such as squatting, are generally disregarded when calculating the two years, but they still need to be evidenced and explained rather than simply asserted. Gathering this evidence before the contractor invoices at 5% — not after HMRC asks for it during a VAT inspection — is the difference between a clean relief claim and a retrospective argument.

Changing the number of dwellings

The second reduced-rate category applies where building work changes the number of self-contained dwellings in a building, regardless of how long it has been occupied. Common examples include:

• Converting a single house into two or more self-contained flats
• Converting several flats back into one single house
• Converting a house let as bedsits, with shared facilities, into fully self-contained flats

As with the empty homes relief, the 5% rate applies to the contractor's qualifying services and matching materials, and the "before and after" state of the building needs to be clearly documented — floor plans, building control records and planning permission for the change of use are the usual evidence a VAT inspector will ask to see.

Non-residential to residential: reduced rate or zero rate?

Converting a non-residential building — a former shop, office, barn or agricultural building — into residential use sits at the boundary between two different reliefs, and which one applies depends entirely on what the converter does with the finished building:

• Sell it or grant a long lease — where the person doing the conversion goes on to sell the freehold or grant a lease of more than 21 years (a "major interest") in the newly residential building, that first grant can usually be zero-rated. VAT incurred on the conversion costs is then recoverable in full, because there is a zero-rated supply to set it against. This is the same principle covered in our guide to developer VAT on new builds, which deals with the zero-rating rules in more detail.
• Keep it and let it out — where the converter retains the building and lets it out as residential property instead of selling, there is no zero-rated sale to recover input VAT against. The contractor's services on the conversion are instead reduced-rated at 5%, and the VAT the converter incurs on professional fees, materials bought directly, and anything outside the contractor's reduced-rated supply is simply a cost, because letting residential property is VAT-exempt.

This distinction catches out developers who plan to sell but end up letting a unit that doesn't shift, or investors who buy a part-converted building assuming the original zero-rating carries over automatically. It usually doesn't — each supply in the chain needs testing on its own facts.

What the reduced rate does not cover

The reduced rate is narrower than developers often assume. It generally will not apply to:

• Materials and fittings bought by the property owner directly, rather than supplied and fitted by the contractor as part of the qualifying work
• Professional fees — architects, surveyors and project managers charge VAT at the standard rate regardless of what relief applies to the building work itself
• Work that goes beyond the qualifying description, such as a significant extension that isn't part of changing the number of dwellings or renovating the empty building itself
• Landscaping, garden buildings and other work outside the fabric of the qualifying dwelling, unless specifically included within the relief's scope

Getting the contract structured so that qualifying and non-qualifying elements are properly split — and invoiced accordingly — is usually a better outcome than a single blended invoice that HMRC can challenge in its entirety.

Getting the paperwork right before work starts

Because these reliefs turn on facts at a fixed point in time — how long the property was empty, what the building looked like before conversion — the evidence needs to exist before the contractor starts charging 5%, not be reconstructed at the point of a VAT inspection years later. A short certificate from the customer to the contractor confirming which relief applies, backed by the underlying records above, protects both parties if HMRC later queries the rate charged.

Common questions

How long must a property be empty to qualify for 5% VAT on renovation?

The property must not have been lived in for at least two years immediately before the renovation work starts. It doesn't need to have been empty for the whole two years for the same reason, and short periods of unauthorised occupation are usually disregarded, but the burden is on the owner to prove the property was genuinely unoccupied.

What counts as changing the number of dwellings for VAT purposes?

It covers work that results in a different number of self-contained dwellings than existed before — splitting a single house into separate flats, converting flats back into one house, or turning a house with bedsits into fully self-contained units.

Is converting a shop or office into flats zero-rated or reduced-rated for VAT?

It depends on what happens next. Selling the finished dwellings or granting a long lease can usually be zero-rated. Converting and then keeping the building to let out means the contractor's services are reduced-rated at 5% instead, because there is no zero-rated sale to recover input VAT against.

Does the reduced rate apply to materials I buy myself?

No. The 5% rate only applies to a contractor's supply of qualifying services together with matching materials they install as part of that work. Materials bought directly by the owner are standard-rated at 20%.
