VAT on new builds is one of the most generous areas of UK VAT law for residential projects, but it is also one of the easiest to misapply. Understanding which rate applies to your project from the outset can save significant sums and prevent costly corrections later.
In broad terms, most genuinely new residential dwellings are zero rated for VAT, while most commercial new builds attract the standard rate of 20 percent. The rules sit within a wider framework that also covers conversions, renovations, self builds and mixed use developments, each with their own conditions and pitfalls.
What Counts as Residential Property for VAT Purposes
Residential property for VAT purposes means a building designed for human habitation, including houses, flats and certain residential care facilities. To qualify for zero rating, the dwelling must be self contained, independently usable and capable of separate sale. It must also be built in accordance with planning permission, with any existing structures on the site normally demolished to ground level before construction begins.
Residential projects can include entirely new builds and certain conversions of non residential buildings into dwellings. How VAT applies in each case depends on whether you are a builder selling completed units, a developer holding units for rent, or a self builder constructing your own home.
VAT for Builders and Developers of New Dwellings
Where a VAT registered builder constructs a qualifying new dwelling and sells it on, that first sale is zero rated for VAT. In practice this means no VAT is charged to the buyer on the sale price, but the builder can still reclaim input VAT on qualifying construction costs such as building materials and subcontractor services, provided those costs directly relate to the zero rated supply.
Not every cost qualifies on the same basis. Carpets, most white goods, fitted wardrobes and other non integral fixtures remain standard rated, and VAT on these items may not be fully recoverable. Mixed use schemes that combine ground floor commercial space with upper floor residential units require careful apportionment of costs between standard rated and zero rated elements, which is an area where errors frequently arise.
Self Builders and the DIY VAT Refund Scheme
Individuals building or converting their own home are not usually VAT registered, meaning they pay VAT on most materials at the point of purchase. To put self builders in a broadly similar VAT position to someone who buys a zero rated new home from a developer, HMRC operates the DIY Housebuilders scheme. This allows eligible self builders to reclaim VAT on qualifying building materials and certain services after the project is complete.
To qualify, the dwelling must be intended as your main home or a non profit communal residence, be self contained and not primarily for business use. You can only make one claim per project using the appropriate HMRC form, and for projects completed on or after 5 December 2023 you have six months from completion to submit that claim. Most structural materials, first and second fix items, and fitted kitchens and bathrooms qualify for the refund, while professional fees, machinery hire and most freestanding appliances do not. Clear invoices and thorough record keeping are essential, as HMRC will reject incomplete or insufficiently evidenced claims.
Residential Conversions and the 5 Percent Reduced Rate
Converting a non residential building such as a barn, office or warehouse into dwellings introduces a different set of VAT rules. Rather than the standard 20 percent rate, HMRC allows a reduced rate of 5 percent VAT on qualifying construction work and building materials incorporated directly into the conversion.
This reduced rate typically applies where the building was non residential in its last lawful use, or where a dwelling has been empty for at least two years before work begins. Builders charge 5 percent VAT on eligible services and incorporated materials, though professional fees from architects or surveyors continue to attract 20 percent. Where the completed conversion produces a new dwelling that meets HMRC conditions, a subsequent sale of that dwelling can be zero rated, allowing the developer to reclaim both the 5 percent and 20 percent VAT incurred on qualifying costs.
Renovations of existing homes that fall outside these conditions generally attract standard rated VAT, though certain energy saving materials and disabled adaptation works can attract zero or reduced rates in specific circumstances.
VAT on New Commercial Builds
Commercial new builds are generally subject to standard rated VAT at 20 percent. Builders and contractors charge VAT on construction services and incorporated materials, and they reclaim VAT on their own costs through regular VAT returns.
The treatment of the completed building then depends on its age and whether the owner has opted to tax. The first sale or long lease of a new commercial property less than three years old is normally standard rated. Once a commercial property is more than three years old, sales and lettings are generally exempt from VAT unless the owner has made a formal option to tax election with HMRC. Opting to tax allows the owner to charge VAT on rents and disposal proceeds, which in turn allows VAT incurred on acquisition costs, refurbishment and ongoing expenses to be reclaimed. Where a buyer is VAT registered and uses the property for fully taxable activities, the VAT charged is generally recoverable in full.
The Domestic Reverse Charge and Construction
The Domestic Reverse Charge applies to many supplies of construction services between VAT registered businesses that fall within the Construction Industry Scheme. Rather than the supplier charging VAT in the usual way, the customer self accounts for VAT on both the output and input side of their VAT return. HMRC introduced the measure to combat missing trader fraud in construction supply chains.
The reverse charge does not apply to supplies made directly to end users who are not themselves in the business of making onward construction supplies, and it does not apply where the work is zero rated, such as on qualifying new dwellings. Developers and contractors must review each contract carefully to determine whether the reverse charge applies and ensure invoicing clearly reflects the correct treatment, as errors can lead to HMRC penalties.

Frequently Asked Questions
What VAT rate applies to a brand new residential dwelling in the UK?
The construction of a new residential dwelling is zero-rated for VAT (0%), provided it is a qualifying building. This means the main contractor charges no VAT on their services, and materials supplied as part of that contract are also zero-rated.
Can I reclaim VAT as a self-builder on my new build home?
Yes. Under the HMRC DIY Housebuilders Scheme, self-builders can reclaim VAT paid on eligible building materials and services used to construct a new home. You must submit a VAT 431NB claim to HMRC within 3 months of receiving your completion certificate. You only get one chance to claim, so accuracy is critical.
When does the 5% VAT rate apply to residential conversions?
The 5% reduced rate applies when you are converting a non-residential building into a dwelling, converting a property into a different number of residential units, or bringing an empty property (unoccupied for 2+ years) back into residential use. It also applies to renovations of properties that have been empty for at least 2 years.
How is VAT treated on a new commercial property compared with an older one?
The sale or lease of a new commercial property (less than 3 years old) is standard-rated at 20% VAT by default. Older commercial properties are generally exempt from VAT, meaning no VAT is charged but also none can be reclaimed. Owners of older properties can choose to “opt to tax,” which makes them standard-rated at 20%, allowing VAT recovery on costs.
