Gas Safe vs CORGI in London: Why the Change Matters and How to Verify Engineers Today
Many London homeowners and landlords who have been managing properties for more than fifteen years still remember the CORGI registration scheme for gas engineers. CORGI was replaced by the Gas Safe Register in 2009, and any reference to CORGI registration in the context of current gas work in London is irrelevant or potentially misleading. This guide explains what changed, why it matters for London property owners, and how to verify that an engineer is currently registered under the Gas Safe scheme.
What Was CORGI and Why Did It Change?
CORGI, which stood for the Council for Registered Gas Installers, was the organisation appointed by the Health and Safety Executive to operate the mandatory registration scheme for gas engineers in the United Kingdom from 1991. Under the CORGI scheme, gas engineers in London and across the UK were required to register with CORGI and to demonstrate their competence in specific categories of gas work in order to carry out gas installations legally under the Gas Safety (Installation and Use) Regulations 1994. The CORGI logo became widely recognised as the mark of a legitimate gas engineer, and London homeowners and landlords were advised to look for the CORGI logo before allowing any gas work to be carried out.
In 2009, the Health and Safety Executive appointed a new organisation, the Gas Safe Register, to take over the operation of the mandatory gas registration scheme from CORGI. The changeover took effect on 1 April 2009, after which CORGI ceased to operate as the gas registration body, and all gas engineers who wished to work legally in the United Kingdom were required to register with the Gas Safe Register. Any engineer who presents CORGI credentials as their current registration is presenting out-of-date documentation, as CORGI registration has not been valid for gas work since April 2009. The Gas Safe Register now maintains the official list of gas engineers who are legally qualified to work on gas appliances and pipework in the UK.
Why the CORGI to Gas Safe Change Matters for London Property Owners
The change from CORGI to Gas Safe registration matters because it defines the legal basis for the registration requirement. A gas engineer in London today must be registered with the Gas Safe Register, not with CORGI, to carry out gas work legally. Any gas work carried out by an engineer who claims CORGI registration but is not registered with Gas Safe is illegal, regardless of how recently the CORGI registration was obtained or renewed. London landlords who commission gas work from an unregistered engineer face the risk that the work is uncertifiable, that any gas appliance covered by the work cannot be legally issued with a gas safety certificate, and that the engineer and the property owner may both face enforcement action under the Gas Safety (Installation and Use) Regulations 1998.
London homeowners who purchased their property before 2009 may have documentation in the property file that refers to CORGI certificates for gas work carried out before the changeover. This documentation is historical evidence of work carried out under the previous scheme and remains valid as a record of the work done at the time. The concern arises only when someone claims that current CORGI credentials authorise them to carry out gas work today, which they do not. If you are reviewing historical property documentation and see references to CORGI certification for work carried out before April 2009, this is normal and does not indicate a problem.
How to Verify a Gas Safe Registered Engineer in London Today
The Gas Safe Register maintains a public online database at gassaferegister.co.uk that allows anyone to check whether an engineer is currently registered and to verify which categories of work they are qualified to carry out. To check an engineer, you need their Gas Safe registration number, which appears on the Gas Safe ID card that all registered engineers are required to carry and to show on request. The front of the card shows the engineer name, the registration number, and the expiry date. The back of the card lists the gas work categories for which the engineer is registered. Always check the expiry date and confirm that the registration is current before allowing any gas work to proceed. Prestige Engineers are Gas Safe registered, and all of our London engineers carry valid Gas Safe identification. We provide the registration number with every quote and welcome clients to verify our registration before work commences.
