What to check when hiring heating engineers in the United Kingdom
MyTrustedTraders ranks on independent public evidence. No ads, no paid placement. Use these checks alongside the evidence on each profile before you decide who to contact.
- Confirm they cover your area and can actually come out in your timeframe before anything else.
- Read recent reviews for reliability and turning up on time, not only the quality of the work.
- Agree the call-out fee up front, and be wary of large upfront deposits for an emergency job.
- Run the Cowboy Checker to confirm the business is real before you let anyone in.

How to judge a heating engineer
Independent, no-ads guidance. The trade-specific checks that matter most, the warning signs, and what to ask before you hire. Use it alongside each trader’s public evidence above.
Verify before you hire
- Check the engineer's Gas Safe Register licence number on gassaferegister.co.uk or text it to 85080: registration is annual and lapses.
- Confirm their Gas Safe card lists the right appliance category for your job (e.g. domestic boilers are listed separately from gas fires).
- For oil heating, verify they are on the OFTEC register at oftec.org: Gas Safe does not cover oil work.
- Ask whether they carry public liability insurance and can self-certify the installation with Building Control.
Warning signs of a cowboy
- They cannot produce a Gas Safe ID card or give you their 7-digit licence number to check.
- They ask for a large cash deposit upfront, especially on an emergency callout, with nothing in writing.
- They quote over the phone without seeing the job, then inflate the price once on site.
- They pressure you to replace the boiler on the spot without a written quote or explanation of what is wrong.
Questions to ask before you hire
- What is your Gas Safe licence number and can I see your current ID card?
- Are you manufacturer-accredited for my boiler brand: and can you register the extended warranty for me?
- Will you self-certify this installation with Building Control, and do I get a certificate?
- What is the full cost, including callout fee, parts, and labour: in writing before you start?
Frequently asked questions
- How do I choose a trustworthy heating engineer?
- Compare the public evidence on each profile: how many independent reviews they have and across how many named sources, the rating and how recent it is, any credential evidence, and the company status. A heating engineer backed by several named sources is harder to fake than one found in only one place.
- Does MyTrustedTraders rank or recommend heating engineers for payment?
- No. There are no ads and no paid placement. Heating engineers are ranked only by the strength of independent public evidence. No one can pay to rank higher, add a badge, or change their reviews.
- Where do the reviews come from?
- They're imported from named public review sources and always shown with the source named. They aren't reviews written on MyTrustedTraders. We cross-check the same business across sources rather than creating new reviews.
- What should I check before hiring a heating engineer?
- Confirm credentials and insurance directly with the heating engineer, get a written quote, and run the Cowboy Checker on the business first. MyTrustedTraders helps you shortlist on the evidence. It doesn't replace your own checks before you hire.
