Answer: Gas Safety (Installation and Use) Regulations 1998
The Gas Safety (Installation and Use) Regulations 1998 (GSIUR) make it a legal requirement for anyone carrying out gas work to be a member of a recognised Gas Safe scheme in Great Britain.
What does a Gas Safe ID card show?
Answer: The engineer's name, registration number, card expiry date and the types of gas work they are qualified to carry out
The Gas Safe ID card shows the engineer's photo, name, registration number, expiry date, and the specific appliance and pipework categories they are competent to work on (listed on the reverse).
What is the penalty for carrying out gas work without Gas Safe registration?
Answer: An unlimited fine and/or up to six months imprisonment
Under the GSIUR, illegally carrying out gas work without registration can result in prosecution, an unlimited fine and/or up to six months imprisonment on summary conviction.
What is an 'immediately dangerous' (ID) situation under Gas Safe procedures?
Answer: A gas fitting or appliance where there is an immediate risk to life if it continues to operate
An immediately dangerous situation is one where a gas fitting or appliance presents a direct, immediate risk to life (e.g., severe gas escape, major CO emission, no flue). The engineer must make it safe without delay.
What must a Gas Safe engineer do if they find an immediately dangerous situation?
Answer: Turn off and disconnect the appliance or supply, label it 'do not use', and issue a warning notice; advise the owner not to use it
When an ID situation is found, the engineer must immediately make the installation safe (isolate, disconnect or cap), label it clearly as dangerous, issue a Gas Safe warning notice and advise the owner not to use it.
What is an 'at risk' (AR) situation under Gas Safe procedures?
Answer: A situation that is not immediately dangerous but could become dangerous if not addressed — the engineer should advise the user to have it repaired promptly
An 'at risk' situation is a gas fitting that is not immediately dangerous but has a defect that could become dangerous. The engineer advises the customer to arrange repair promptly but does not immediately disconnect.
