Do I need a HETAS certificate for insurance? Stove guide

Whether you need a HETAS certificate for insurance depends on the policy, not on one national rule. UK home insurers can ask about a stove or log burner, and they can accept more than one kind of installation record when a certificate is missing. Notice plates and chimney records also have a place among the evidence a customer can show an insurer.

Do insurers require a HETAS certificate?

No UK-wide home insurance rule requires a HETAS certificate for every stove or log burner. Each insurer's position rests on its own contract. As a result, the answer for your customer depends on their policy, what they told the insurer and the evidence they can produce.

What does your policy require?

The policy wording sets the insurer's requirements, along with the answers given when cover was taken out or renewed. Those conditions can go further than Building Regulations. In practice, a stove installation that meets the law can still fall short of a stricter contractual condition.

That is why the timing of the conversation with the insurer matters. Before any stove work starts, the homeowner should ask what must be disclosed and which installation evidence the insurer will accept. Keeping that answer in writing settles the question if a claim arises later.

What happens if you make a claim?

A missing HETAS certificate does not automatically make a stove illegal, and it does not automatically invalidate home insurance. Compliance, notification history and policy conditions are three separate questions. The effect on a claim depends on the policy wording, what was disclosed, the circumstances of the loss and the applicable claims rules: missing paperwork means neither automatic rejection nor guaranteed payment.

When investigating a fire-related claim, an insurer may ask for evidence that the stove was installed compliantly. An optional home-emergency section that excludes solid-fuel systems does not necessarily exclude fire damage under the buildings cover.

Do thatched homes have different conditions?

Thatched homes can carry extra stove and chimney conditions on top of those for an ordinary house. One specialist thatched-home policy requires the broker to be told when an open fire or a wood- or solid-fuel stove is installed. The policy should therefore be checked before the appliance is fitted or used.

Some conditions go further and cover chimney upkeep. One specialist thatched-property policy requires professional chimney cleaning, plus lined and insulated chimneys for stoves and burners. It also requires an inspection by a HETAS-registered company at least once every 3 years.

That inspection condition covers the chimney's ongoing condition. It is not necessarily a demand for a HETAS installation certificate, so the two requirements should be read separately in the policy.

Which installation documents can your insurer accept?

An insurer asking for a HETAS certificate is looking for evidence of a compliant installation. Which document provides that evidence depends on the route the installation followed. Once the route is identified, the correct paperwork follows from it.

Which certification route applied?

In England and Wales, solid-fuel installations have been notifiable since 1 April 2005. That means the local authority must be told about the work. A wood burning stove or a multi-fuel stove can follow one of these routes:

• HETAS competent-person scheme: a HETAS registered installer self-certifies the work and notifies the local authority.
• Another authorised competent-person scheme: HETAS is one authorised scheme, not the only lawful one.
• Building Control route: the authority runs its own process and issues completion evidence instead of a HETAS certificate.

Under HETAS's England and Wales scheme, the Certificate of Compliance is the registered installer's declaration that the relevant Building Regulations were met. In contrast, the Building Control route ends with the authority's own completion document. Either one may explain why the other is absent.

What does each document establish?

A competent-person certificate should reach the homeowner within 8 weeks of completion, according to GOV.UK. Beyond that, the standards the work is judged against are set out in Approved Document J in England. It covers combustion-appliance requirements including air supply, hearths, flues and chimneys, and its 2022 amendments took effect on 1 October 2022.

Both certificates provide evidence of compliance with those requirements, and HETAS is not the only valid source. A Financial Ombudsman decision on a log burner recognised local-authority Building Control certification as an alternative to HETAS certification. It rejected the claim that only HETAS could certify the installation.

What supporting evidence should you keep?

No UK-wide evidence pack for stoves exists. Compliance starts with asking the particular insurer which documents it requires or accepts, then keeping its written answer. Alongside the certificate, the following records strengthen the file:

• Installer's invoice and registration details: show who did the work and when.
• Commissioning sheet and manufacturer's instructions: record how the appliance was set up and what it requires.
• Appliance identification and installation photographs: confirm what was fitted and how it looked once complete.

None of these records certifies compliance with Building Regulations on its own. For a DIY installation, Local Authority Building Control needs evidence that the work complies. An inspection against Approved Document J may show remedial work is needed, but the Building Control officer decides whether to sign the installation off.

How do you resolve a missing HETAS certificate?

A missing certificate can mean three different things: one issued and then lost, an installation approved through Building Control, or work that was never notified or approved. Each situation has its own remedy, so working out which one applies comes first.

Was a certificate ever issued?

Where a HETAS-registered installer did the work, ask them for the Certificate of Compliance, the notification reference and the commissioning paperwork. HETAS can then be asked to confirm its notification record. A record search uses the installation address, approximate date, installer or business name and registration number if known, plus appliance details, invoices and photographs. If the installer has stopped trading, the work may still be traceable through HETAS or Building Control. Their present registration status says nothing about what was notified at the time.

What if the installation followed another route?

If HETAS holds no record, the next step depends on whether another body approved the work. Each case points to a different source of evidence:

• Building Control approval: request the authority's completion document or other installation record rather than a duplicate HETAS certificate.
• Competent-person notification held by the council: councils may record these notifications without holding or reissuing the scheme certificates.
• No record at all: arrange an assessment by a competent solid-fuel professional.
• Possible regularisation: ask the local authority Building Control Body whether retrospective approval is appropriate.

Where the installation has no record, safety comes before paperwork. Any doubt about the installation should be resolved before the stove is used again.

A chimney sweep cannot fill the gap either. HETAS sweep-and-service conditions only allow technicians to certify their own sweeping and servicing. As a result, a sweep cannot issue a HETAS installation certificate for another person's historic work.

Can unauthorised work be regularised?

GOV.UK describes regularisation as retrospective approval from a local authority for qualifying unauthorised work carried out after 11 November 1985. The resulting certificate is evidence of compliance with the specified Building Regulations requirements, but not conclusive evidence. Before issuing it, the authority may require concealed work to be opened up and defects corrected. Charges depend on the authority and the inspection required, with no single UK-wide fee.

Age alone does not put undocumented work beyond enforcement. In England, the period for a Building Control removal-or-alteration notice became 10 years on 1 October 2023. The corresponding Welsh change took effect on 1 July 2026.

Where do plates and chimney records fit?

Once the certificate question is settled, physical plates and maintenance records complete the file. They support the installation evidence by showing what was fitted and how the system has been maintained since. They do not replace certification.

What can a notice plate show?

Building Regulations requirement J5 calls for information on the performance of a hearth, fireplace, flue or chimney when one is provided or extended. A robust, indelibly marked notice plate, securely fixed in an obvious position, is one way to provide it. It can be fixed beside the electricity consumer unit or near the chimney or hearth it describes.

• Appliance details: identify the stove the system was installed for.
• Installation details: record the installation itself, such as who fitted it and when.
• Suitable chimney fuels: state which fuels the chimney can safely serve.

A notice plate corroborates installation details, but it does not prove Building Control notification or that a Certificate of Compliance exists. Its legible details are worth photographing during a record search. The manufacturer's appliance data plate is a separate item: it identifies the stove and may show its serial number, but it is not Building Control approval.

What do chimney records add?

A chimney-sweeping certificate records later maintenance, not the original installation's compliance or notification. The National Association of Chimney Sweeps requires its members to issue one after each sweep and to record any defects or dangerous occurrences. HETAS consumer material recommends regular sweeping and annual servicing after installation. Flue or liner information, inspection and test reports, and servicing and repair records show the system's condition over time.

The same principle applies to the plates installers supply. DataPlate Hub offers customised data notice plates for reordering for stoves, flues and chimneys.
