Gas work is restricted by law to Gas Safe registered engineers. If they'll touch a boiler or any gas appliance, confirm they're currently on the register before you hire - it's free and takes a minute.
Check the Gas Safe RegisterBy 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.
