Gas central heating systems should only be installed and repaired by a Gas Safe registered engineer.

Working with gas can be dangerous and it is important that you hire a tradesperson who is qualified to do the job safely.

Follow these steps to check a central heating engineer is Gas Safe registered before hiring them:

• Ask to see their ID badge. All Gas Safe registered engineers have an ID badge displaying their photo, qualifications and registration number

• Search the Gas Safe register. Enter an engineer’s ID number or business name into the search tool on the Gas Register website

  Do not hire a heating engineer if you are unable to verify their Gas Safe registration. Gas leaks can be fatal and hiring a tradesperson without the relevant qualifications is a risk you don’t want to take.
