# How to check a boiler engineer’s registration

Use official registers and match the licence scope to the planned gas work.

Updated 2026-11-10. Also on the [web page](https://boilerpros.fyi/guides/check-an-engineer-registration).

Ask who will attend, which business employs them and which registration covers the proposed work. A directory entry, a logo or a paid ownership badge does not establish a current gas qualification.

## Great Britain

Use the official UK gas register to check the engineer or business. Start from the register link on HSE's homeowner guidance. HSE says engineers carry an ID card and that their gas work competencies are marked on its back. Match the person, validity and appliance categories before work starts. [HSE, checked 2026-11-10.]

The register's own pages blocked our direct fetch on 2026-11-10. The instructions here rely on the fetched HSE page, which links to the register. Open the official register yourself before booking. Do not treat our dated source check as a live licence check.

## United States

Use the state or local licensing authority for the job location. Do not assume a licence from another state covers your address.

The Massachusetts Board of State Examiners of Plumbers and Gas Fitters has a “Check a license” link. Its page describes licences for journeyman and master plumbers and gas fitters. Follow that link and search the contractor or individual details. [Massachusetts Board, checked 2026-11-10.]

California's Contractors State License Board has a public licence lookup. Its page says users can verify licence information and complaint disclosures. Confirm the classification and status, then ask the authority whether that scope covers your planned work. This guide does not select a contractor classification for you. [CSLB, checked 2026-11-10.]

## Canada

Use the provincial or territorial authority for the property. Technical Safety BC has a “Find a Licensed Contractor” search for regulated work in its jurisdiction. Search the business and confirm the relevant gas work with the authority. This BC example does not establish requirements elsewhere in Canada. [Technical Safety BC, checked 2026-11-10.]

## Keep a check record

Save the official result URL, date checked, name, number and relevant scope. If a detail differs from the quote, ask the business to explain it before work starts. Check subcontractors too. Do not assume that a company record lists every person who may attend.

If the result is absent, expired or unclear, contact the regulator. Avoid drawing a conclusion from a similar name alone. Memberships and manufacturer training may be useful additional information, but they do not replace the appropriate official check.
