A new self-build project can involve thousands of pounds in VAT, but did you know you may be able to reclaim some of it? If you are building your own home, understanding the VAT rules can help you recover eligible costs and reduce the overall cost of your project.
You may be able to reclaim VAT on eligible costs through HMRC’s DIY Housebuilders Scheme. You need to make one claim using form VAT431NB within 6 months of receiving your building control completion certificate.
In this blog, we explain who can claim, which costs qualify, what documents you need, and how to submit your VAT reclaim correctly.
The DIY Housebuilders Scheme allows eligible people building a new home to reclaim VAT on qualifying building materials they buy themselves.
While qualifying construction work is usually zero-rated, materials bought directly may include VAT. The scheme helps self-builders recover eligible VAT and avoid paying more than necessary.
Not every purchase qualifies, so it is important to check the VAT rules before buying materials.
You may qualify if you are:
The property must satisfy HMRC's definition of a new dwelling, including having separate access and being capable of independent occupation.
If you're unsure whether your project qualifies for a VAT reclaim on new build, seeking professional advice before construction begins can prevent costly mistakes later.
Many people assume every construction cost attracts VAT, but that's not always the case.
When considering VAT on building construction, different supplies receive different VAT treatments depending on who supplies them and the type of work involved.
Generally:
Knowing the difference helps ensure you only include eligible expenses when claiming VAT on new build projects.
HMRC generally allows VAT recovery on building materials that become part of the completed property.
Common qualifying items include:
The materials must normally be incorporated permanently into the building.
A successful self build VAT reclaim depends on maintaining detailed purchase records throughout the project.
Some purchases are excluded, even if they were necessary during construction.
Examples include:
Many applicants incorrectly include these costs, which can delay a VAT reclaim on a new build application.
One area that often causes confusion is 5 VAT on building work.
While most qualifying new-build construction services are zero-rated, some renovation and conversion projects may qualify for the reduced 5% VAT rate instead.
Examples may include:
However, the reduced rate does not automatically apply to every construction project. The correct VAT treatment depends on the property's history and the work being carried out.
Understanding whether 5 VAT on building work applies to your project is important before agreeing contracts with builders.
The process is relatively straightforward if you've kept accurate records.
You can only apply once construction has been completed and you have received the relevant completion certificate.
Sort invoices into qualifying and non-qualifying purchases.
Use the appropriate DIY Housebuilders' Scheme application form.
Include copies of all eligible VAT invoices and completion evidence.
HMRC will assess your application and may request additional information before processing your repayment.
Many applicants benefit from professional support when claiming VAT on new build projects to reduce errors and avoid unnecessary delays.
Recovering VAT on a self-build project can significantly reduce the overall cost of constructing a new property. By understanding the rules surrounding VAT on building construction, keeping accurate records, and submitting your application correctly, you can improve your chances of receiving the maximum repayment available.
