HETAS is the UK’s official body for solid fuel heating. A HETAS registered installer self-certifies against building regulations — no building control application, no council inspection, no fee. Compliance certificate issued on the day.
HETAS is the government-recognised body for solid fuel heating in the UK. It is the only Competent Person Scheme that specialises in solid fuel appliance installation and chimney work. A HETAS registered installer has been assessed in the field, not simply granted a membership. The registration requires demonstrated practical competence against the technical requirements of Approved Document J of the Building Regulations.
Anyone can call themselves a stove fitter. A HETAS registered installer has been assessed on the job, holds a government-recognised competent person registration, and can issue the legal certificate your conveyancer and insurer will ask for. Verify the registration yourself at hetas.co.uk before you call.
A HETAS registered installer self-certifies against building regulations. No separate building control application. No council inspection. No fee to the local authority. The compliance certificate is issued on the day the job is done.
When an unregistered fitter carries out a stove installation or chimney lining, the homeowner must submit a building notice to the local authority, pay an inspection fee, wait for a council inspector, and then obtain sign-off separately. The HETAS route removes all of that. The installer certifies the work, notifies the local authority through HETAS, and hands you the certificate before leaving.
Installer self-certifies. HETAS notifies local authority. Certificate issued on completion. No application. No inspection fee. No wait.
Homeowner submits building notice. Inspection fee paid to council. Wait for inspector availability. Sign-off obtained separately. Risk of non-compliance if inspection fails.
HETAS registration is specific to the scope of work. Our registration covers all four installation competences relevant to domestic solid fuel appliances and chimney systems.
Wood burning stoves, log burners, multi-fuel stoves and solid fuel room heaters. Covers supply and fit or fit only. Full installation process from survey through to commissioning and HETAS certificate issue.
Flexible stainless steel flue liner installation for open fires and solid fuel appliances. Diameter specified to Approved Document J requirements. 316L standard grade, 904L for high temperature applications. Smoke leakage test on completion.
External twin wall flue systems rising on the outside of the building. Applicable where no existing chimney is present — extensions, outbuildings, new builds. Wall penetration, rising sections, wall brackets and roof termination all within scope.
Internal twin wall through ceilings and floors. Firestop plates mandatory at every ceiling and floor penetration per Approved Document J. Minimum clearance from combustibles maintained at each level. Specialist scope requiring precise installation to Document J diagram requirements.
Your buyer’s solicitor will request evidence of building regulation compliance for any chimney or stove work carried out at the property. The HETAS compliance certificate is the document. Without it, you face retrospective building regulation approval from the local authority, which is time-consuming and can delay or complicate a sale. Getting the certificate at installation stage means it stays with the property permanently.
Many home insurance policies include conditions requiring that solid fuel appliances are installed professionally and that evidence of compliance is retained. A HETAS compliance certificate from a registered installer is the standard form of proof accepted by insurers. If you make a claim following a fire or appliance fault and cannot provide a certificate, your insurer may investigate the basis of the claim before settling. A HETAS installation removes that question entirely.
Every HETAS registered installer holds a current registration number searchable on the HETAS Find an Installer tool at hetas.co.uk. Search by postcode, confirm the registration is current, and check the scope of competence listed. You should be able to confirm any HETAS installer’s registration before getting in touch — including ours.
Registration under HETAS is not a permanent status. It requires renewal and continued compliance with scheme requirements. An installer whose registration has lapsed cannot legally self-certify. Checking at hetas.co.uk before booking is straightforward and takes thirty seconds.
What is a HETAS registered installer?
A HETAS registered installer is approved under the HETAS Competent Person Scheme — the government-recognised scheme for solid fuel appliance and chimney installation. They can self-certify their work against building regulations and issue a HETAS compliance certificate.
What is the difference between a HETAS installer and an unregistered fitter?
A HETAS registered installer has been assessed on the job, holds a registered competent person number, and can legally self-certify installations. An unregistered fitter cannot self-certify — the homeowner must notify building control separately and pay for an inspection.
Can I verify your HETAS registration before booking?
Yes. Every HETAS registered installer appears on the HETAS Find an Installer search at hetas.co.uk. Search by postcode and confirm registration before you get in touch.
What does the HETAS compliance certificate cover?
It covers the installation against Approved Document J of the Building Regulations. Issued to you on completion, with a copy sent to HETAS who notify your local authority. Permanent legal record.
