A HETAS Company ID is the 4-digit number used to find a registered business in HETAS’s “Check Business” search. HETAS is a specialist solid-fuel registration body and an authorised competent-person scheme operator in England and Wales; it is not the only authorised scheme listed by government.
HETAS maintains the register at hetas.co.uk. There’s no public API — verification is done via their interactive forms. Reputable third-party tools (this page included) link to HETAS’s own search rather than maintaining a parallel database.
What to do if the ID doesn’t check out
- Pause before work starts. A failed search can be a typing error, an outdated detail or a false registration claim. Ask the business to explain and verify the name and ID directly with HETAS.
- If the claim is false, get consumer advice. Your cancellation or refund rights depend on the contract and circumstances; Citizens Advice or the relevant local consumer service can explain the next step.
- Report to HETAS: info@hetas.co.uk or 01684 278170. HETAS cooperates with Trading Standards on serious cases.
- Find a properly registered installer via the installer matching form or HETAS’s own postcode search.
Quick reference
- HETAS Company ID format: 4 digits, no letters
- HETAS Registered Operative card (renamed from the Installer card in November 2025): physical credential that should be shown on site
- Public Liability Insurance: minimum £2 million is a HETAS registration requirement
- Certificate of Compliance: issued within 2 weeks after a HETAS installer notifies eligible England or Wales work; other nations use different approval records
- Replacement certificate: £36 via hetas.co.uk
- Alternative approval: before work starts, ask the relevant authority which building-control or building-standards route applies; do not assume a later regularisation certificate is automatic

Frequently asked questions
How do I verify a HETAS-registered installer?
Three ways: (1) ask for their 4-digit HETAS Company ID and check it on hetas.co.uk/consumer/services/installers/ via the "Check Business" tab, (2) ask to see their HETAS Registered Operative card, (3) confirm they carry minimum £2 million public liability insurance.
Where do I find a HETAS Company ID?
Ask the business for its 4-digit HETAS Company ID and registered name, then use the Check Business tab in HETAS’s live search. If the details do not match, pause and verify them directly with HETAS before work starts.
What happens if my installer’s HETAS ID doesn’t check out?
Pause before work starts and check for a typing or business-name mismatch. Ask HETAS to verify the registration directly. If a business made a false registration claim, preserve the quote and messages, report the claim to HETAS and get consumer advice before cancelling or seeking a refund.
Can I check if a past install was HETAS-certified?
Search HETAS’s certificate database by postcode or reference number. If a record exists, the current replacement-copy fee is £36. In England and Wales the record is also used for Local Authority notification; Scotland and Northern Ireland use separate approval processes.
What if no record exists for my install?
For work in England or Wales, ask the installer and HETAS to confirm whether notification exists, then contact Local Authority Building Control about the available route. Fees, evidence and remedial requirements vary locally. A missing HETAS record is not the test for Scottish or Northern Irish approval.
Does HETAS have a public API I can query?
No — HETAS doesn’t publish a public API for installer or certificate verification. The search tools on hetas.co.uk are web-based forms requiring email verification per session. Third-party tools (like this page) link to HETAS’s own search rather than maintaining a parallel database.
