report an illegal gas FittER
Do you suspect that someone is working on gas appliances
without being Gas Safe registered?
By law, all engineers undertaking gas work in the United Kingdom,
Isle of Man, and Guernsey must be registered with Gas Safe
Register. Businesses can only register if their engineers are
competent and hold up to date and appropriate qualifications.
You can check if your engineer is registered by using our 'check a gas engineer
' service online or by
calling us on 0800 408 5500
Anybody who is carrying out gas work and is not registered with Gas
Safe Register may be breaking the law. This includes a registered
engineer working out of scope of their qualifications, a previously
registered business continuing to work without registration, and
gas workers who have never been registered.
Note: For information on what constitutes gas work, please see our
Bulletin 014 ‘Gas Work’
if you are a registered engineer, or
contact our technical department if you are a customer. The
technical department can be contacted by phoning 0800 408
or 01256 650 005
and pressing option
