Find an Engineer

Gas Safe Register is the official list of businesses that are legally permitted to carry out gas work. Every registered business employs an engineer(s), who is issued with a Gas Safe ID card. Not all engineers are qualified to do all types of gas work – so remember to check their ID card before any work is carried out.

Find by Location

To find a Gas Safe registered business simply select whether the work you need doing is in a domestic or commercial property, enter your postcode into the box below and click 'Find'.
