HETAS Certificates and Selling Your Home: What You Need to Know

HETAS Certificates and Selling Your Home: What You Need to Know

Colin Whitmore · 17 Sep 2026

Selling a home involves a lot of paperwork, and if you have a wood burning stove, one document that is likely to come up early in the conveyancing process is a HETAS certificate. Buyers, solicitors and mortgage lenders all want reassurance that the stove was installed correctly and safely. Without that paperwork, your sale could slow down or, in some cases, fall through entirely.

We install wood burning stoves right across the UK and we issue HETAS certificates as a standard part of every installation we carry out. In this article we walk you through what the certificate covers, why it matters when you sell, and what your options are if yours is missing.

What Is a HETAS Certificate?

HETAS stands for Heating Equipment Testing and Approval Scheme. It is the official body recognised by the government to approve solid fuel heating appliances, fuels and services in the UK, including wood burning and multi-fuel stoves.

When a HETAS-registered installer fits a stove, they are authorised to self-certify the installation under Building Regulations Part J, which covers combustion appliances and fuel storage. Once the work is done and has passed inspection, the installer notifies the local authority building control on your behalf and issues you with a certificate of compliance.

That certificate is your official proof that:

  • The stove was installed by a competent, registered engineer
  • The installation meets UK Building Regulations
  • The flue, hearth and clearances were checked and approved
  • The work has been notified to the local authority

You can find out more about how our certification process works on our HETAS Certification service page.

Why Solicitors and Buyers Ask for It

During the conveyancing process, the buyer's solicitor will raise enquiries about any alterations or additions to the property. A wood burning stove is a fixed installation that affects the building fabric, so it falls squarely into that category.

If you cannot produce a HETAS certificate or a building regulations completion certificate, the solicitor is likely to flag the installation as unverified. This can lead to:

  • Requests for an indemnity insurance policy, which some insurers will not offer
  • Delays while further inspections are arranged
  • The buyer asking you to reduce the asking price to account for remedial work
  • In some cases, the buyer pulling out of the purchase

Mortgage lenders can also take a cautious view. If a surveyor notes the stove has no certification, the lender may insist on a further inspection before releasing funds.

Having the certificate ready from the outset keeps the process straightforward. It shows the buyer that the installation was done properly and gives everyone in the chain confidence to proceed.

What If the Certificate Is Missing?

This is a common situation, particularly where a stove was installed by a previous owner or fitted before HETAS registration became widespread. If you cannot locate your certificate, you have a few options.

Check with the Installer

If you know who installed the stove, contact them directly. A HETAS-registered installer keeps records of all notifications submitted to the local authority and may be able to provide a copy or confirm the registration number.

Contact Your Local Authority Building Control

Because HETAS installers notify the local authority as part of the self-certification process, there should be a record held by your local building control department. You can request a search or a copy of the notice, although there may be a small admin fee involved.

Arrange a Retrospective Inspection

If no records exist, the most reliable route is to have the installation assessed by a HETAS-registered engineer. Our team can inspect the stove, flue liner, hearth and all associated components to determine whether the installation meets current Building Regulations. If it does, we can then notify building control and issue the appropriate documentation. If remedial work is needed, we will carry that out before certifying.

Our stove servicing and inspection service is a good starting point, and we can advise you on the next steps from there.

New Installations: Get It Right from the Start

If you are having a stove installed and you are thinking about selling in the future, the single most important thing you can do is use a HETAS-registered installer and keep the certificate somewhere safe.

Every installation we carry out at woodburners4u is handled by our HETAS-registered engineers. We manage the building control notification for you and hand over the certificate once the work is complete. You should store it with your other property documents, ideally alongside any planning permissions, chimney lining records and appliance manuals.

Our stove supply and installation service covers everything from choosing the right appliance to completing all the necessary paperwork, so you have a complete and compliant record from day one.

If you live in Norfolk or Suffolk and need certification support, our local teams cover both areas. You can find more detail on our Norfolk HETAS certification page and our Suffolk HETAS certification page.
