Understanding the UK’s Safety Standard for Gas Engineers
What Is the Gas Safe Register?
The Gas Safe Register is the UK’s mandatory regulatory body for gas safety, officially designated by the Health & Safety Executive (HSE). It replaced the previous CORGI scheme in April 2009 in Great Britain and in 2010 in Northern Ireland, Jersey, Guernsey, and the Isle of Man
Being listed ensures that an engineer or company is legally authorised to install, service, or repair gas appliances—including boilers, cookers, fires, and pipework—for natural gas or LPG

Who Is a Certified Gas Safe Engineer?
A Gas Safe Registered Engineer is a qualified individual who holds recognised gas safety certifications (e.g., CCN1, CENWAT, CKR1) and has completed the ACS assessment required for their scope of work. Registration grants them both a licence and an ID card showing their photo, registration number, and the types of gas work permitted
- Engineers undergo an initial probationary period (typically three months), during which their work is monitored—record-keeping and post-job reports are mandatory
- Registration must be renewed annually, and ACS qualifications usually refreshed every 5 years

Why Gas Safe Registration Matters
- Legal requirement: It is illegal for individuals or businesses to perform gas work without proper registration—this includes installation, servicing, repairs, and pipework
- Public safety: Faulty gas work risks gas leaks, carbon monoxide poisoning, fires, and explosions. Gas Safe helps identify unqualified practitioners and takes action to protect consumers
- Consumer trust: Customers can verify an engineer’s credentials via their Gas Safe ID card or the official Gas Safe Register website, using either the engineer’s 7‑digit licence number or the business registration number
What A Gas Safe Registered Company Must Do
Gas Safe Registered businesses are bound by strict requirements:
- Employ at least one Gas Safe registered individual
- Limit work to the qualifications and scopes the business is authorised for
- Renew their registration annually
- Stay compliant with Health & Safety regulations, including the Gas Safety (Installation & Use) Regulations 1998
- Allow inspections and cooperate with any investigations
- Use the Gas Safe logo properly and clearly on materials

Why Choose a Gas Safe Registered Engineer?
- Compliance & Professionalism: Only qualified engineers legally handle gas appliances in the UK.
