What to do if no HETAS certificate was issued for a stove

A missing HETAS certificate does not always mean the stove was never approved. Knowing what to do if no HETAS certificate was issued starts with working out which case you are dealing with.

Was a HETAS certificate ever issued?

Compliance starts with the paperwork trail, not the certificate alone. When a certificate is missing, the first job is to find out whether the installation was notified at all, and through which route. That answer decides which remedy fits.

Why might the certificate be missing?

The absence of a document from a wood burner file does not, on its own, show that the stove is unsafe or unlawful. The gap falls into one of four situations, and each calls for a different remedy.

• Issued and lost: the certificate exists on record and only the paper copy has gone missing.
• Notified but never received: the work went through the scheme, but the homeowner never got the document.
• Never notified: the stove installation was not reported through any approved route.
• Notified elsewhere: another authorised competent person scheme or Building Control holds the record.

Since 1 April 2005 in England and Wales, the legal requirement for solid fuel installations has been notification under the Building Regulations, not holding a HETAS certificate as such. Schedule 3 of the Building Regulations 2010 lets an appropriately registered installer self-certify this work. As a result, an empty HETAS search does not rule out a record held by another scheme or by Building Control.

Trace the installer and notification

Previous owners, conveyancing files, invoices, emails, guarantees, commissioning records, photographs and a notice plate can all help identify who fitted the stove and when. None of them alone proves Building Regulations approval. Their value lies in pointing you to the installer.

• Written request: ask the original installer for the installation date, notification reference, certificate and proof that this particular job was notified.
• Paper trail: keep their reply alongside the invoice, messages and commissioning paperwork.
• Closed businesses: trace a former trading name, successor business or the individual installer before you contact HETAS.

Timing matters when the installer does not provide the HETAS certificate: a HETAS Registered Business must submit its notification within 14 calendar days of finishing the work, and HETAS then has 30 days to notify the local authority. Beyond that, the HETAS business check confirms only that an installer is registered. It does not show that your installation was notified.

Search for a record and obtain a copy

HETAS's certificate search accepts a property postcode or a certificate reference, and it verifies your email before showing a matching record. Once a record appears, check that the address, installation date and scope of work match the stove in front of you.

If the certificate never arrived, you can contact HETAS about a replacement within two months of installation. After two months, a duplicate charge applies: HETAS lists a replacement certificate for an existing record at £36. The route to obtaining a HETAS certificate depends on that original record existing.

If HETAS holds nothing, approach the scheme the installer belonged to for solid-fuel work at the time. Failing that, ask the Building Control body that handled the installation for its application, completion or archived records.

What if no compliance record exists?

Once every search comes back empty, the question changes. Instead of how to find the certificate, it becomes how to show that the installation complies. The answer lies with Building Control, not with a new certificate from a different installer.

Can an installer certify it retrospectively?

The distinction lies in who did the original work. Only the registered installer responsible for that work can complete and sign its HETAS Certificate of Compliance, and a replacement is only possible for an existing record. If you don't have a HETAS certificate and none was ever issued, another installer cannot produce one after the event.

• Visual inspection: a different HETAS registered installer cannot certify a historic installation simply by looking at it.
• Re-commissioning: a suitably registered installer may inspect and re-commission an existing log burner, but this does not mean the original work can be notified retrospectively.
• Unknown history: some installers will only take responsibility after removing and reinstalling the stove.
• Unpaid service: if the installer was paid to arrange certification and did not, you may have a contractual complaint.

A contractual claim against the installer and the stove's compliance are separate matters. Even if the complaint succeeds, the installation itself still needs to be assessed through a recognised route.

Ask about the applicable Building Control route

In England, local authority Building Control can regularise qualifying unauthorised work under regulation 18 of the Building Regulations 2010: the work must have been done on or after 11 November 1985. Regularisation is not a retrospective HETAS certificate, and approval is not guaranteed. For your enquiry, provide the installation date, appliance and flue details, photographs, plans and any surviving installer records. The authority may require opening-up, tests, corrective work and further inspection before it decides. Fees vary by authority, and testing, repairs and reinstatement can add costs. There is no universal deadline for stoves, so confirm the available route before you commission work. In Wales, ask the appropriate Building Control body. In Scotland, ask the local authority verifier about warrant and completion-certificate procedures. In Northern Ireland, ask the district council's Building Control service.

Can the stove be used meanwhile?

No blanket rule says you must stop using a wood burning stove just because its paperwork is missing. Even so, missing paperwork does not show a compliant installation. Where safe operation cannot be established, have a competent solid-fuel professional assess it before use. Smoke leakage, a carbon monoxide alarm, scorching, overheating or suspected flue damage all mean stopping use and getting urgent advice. Carbon monoxide has no colour or smell, and carbon monoxide poisoning can be fatal.

An assessment may cover the appliance, hearth, clearances, ventilation, chimney and flue, carbon monoxide protection and commissioning tests against the applicable safety standards. England's Approved Document J covers these points, and its amendments on carbon monoxide alarms took effect on 1 October 2022.

Will missing paperwork affect home insurance?

Missing paperwork does not automatically invalidate a home insurance policy. What happens depends on the policy wording, what you have disclosed, the condition of the installation and the circumstances of any claim. That is why checking the policy comes before anything else.

What does the policy require?

Terms covering solid fuel appliances may ask for evidence of Building Regulations compliance, competent installation, sweeping, servicing or fire precautions. Read each clause against the documents you actually hold.

Gaps matter most at claim stage. An insurer may dispute a fire or carbon monoxide claim if evidence the policy requires is missing. Equally, a recent inspection should not be assumed to satisfy the insurer's requirements.

What should you tell the insurer?

Tell the insurer whether the original certificate was lost, was never issued or is still being traced. These situations carry different risks and should not be treated as the same.

Ask the insurer in writing which evidence it accepts. Its reply should state whether it needs Building Control documentation, further testing, repairs or for the stove not to be used.

Keep the inspection report, any chimney sweep visit or sweeping certificate, the latest servicing record, photographs, commissioning evidence and details of corrective work. Each records a particular check or maintenance task, not the original approval. The same applies to a notice plate or appliance data plate: either may help identify installation details, but neither should be assumed to satisfy an insurer asking for an installation certificate.

Can you sell or buy without stove paperwork?

A house can be sold with a wood burner whose certificate is missing. The difficulty is evidence: the buyer, conveyancer, lender or insurer may ask for further documents, an inspection or a fix. No single outcome applies to every sale.

What can a buyer reasonably request?

The Law Society's 2025 TA6 explanatory notes say that a solid-fuel appliance installed on or after 1 April 2005 would have needed either a Building Control completion certificate or an installer Building Regulations compliance certificate. Buyers therefore have grounds to ask about:

• Installer: who fitted the stove and under which registration.
• Date: when the installation was completed.
• Notification: whether it went through a competent person scheme or Building Control.
• Condition: whether the appliance and its surroundings need a technical assessment.

These answers show whether the gap is a missing document or missing approval. A record that can be traced only calls for a copy. Without one, the buyer may want an assessment before going ahead.

How should the paperwork gap be handled?

As the seller, give the buyer's conveyancer all the installation evidence you have. The fixtures-and-fittings form should state clearly whether the stove and its fittings are included. Useful handover records include the appliance instructions and the latest sweeping and servicing records.

Conveyancing indemnity insurance can cover specified enforcement risks. It does not prove safety or compliance, may not cover reinstallation and may not satisfy a lender. Before contacting Building Control during a sale, ask the conveyancer how this might affect the transaction or any indemnity policy, and never conceal the missing paperwork.

What does a notice plate establish?

Approved Document J's J5 information requirement can be met with a robust, indelibly marked notice plate fixed in an obvious position. Data Plate Hub's standard notice plate for stoves and chimneys records details of the hearth, chimney or flue and the generic appliances they can safely accommodate.

For installers who want their name on the record, Data Plate Hub also offers a customised data notice plate for log burners. It carries your business branding alongside the installation details.

A notice plate provides a permanent record, but it does not replace a Certificate of Compliance or Building Control approval. Equally, an installer number on the plate does not prove that this particular stove installation was notified.
