Before you hire a gas engineer
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.
