Gas heating needs a Gas Safe registered engineer
Anyone paid to work on gas appliances in a home must be on the Gas Safe Register and competent for that type of gas work. Their competencies are listed on the back of their Gas Safe ID card, so ask to see it.

Heating: common questions
Why are some of my radiators cold?
Cold at the top usually means trapped air and the radiator needs bleeding. Cold at the bottom or cold throughout can point to sludge, a stuck valve or a system that needs balancing. A heating engineer can find the cause.
Do I need a heating engineer or a plumber?
For anything involving a gas boiler or gas appliance, you need a Gas Safe registered engineer. For radiators and pipework on their own, either may be able to help. Tell us the problem and we'll match you with the right person.
