What to check when hiring gas engineers in London
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.
- By law, anyone working on your gas appliances must be on the Gas Safe Register — ask to see their Gas Safe ID card and check the licence number at gassaferegister.co.uk before they start.
- Never let an unregistered person touch your gas: unsafe gas work risks carbon monoxide poisoning, fire and explosion, and is a criminal offence.
- For a boiler or appliance install, get the work and price in writing and keep the Gas Safe / Building Regulations certificate they are required to give you.
- 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.
