Gas Safe Registered Engineers Across the UK

The Gas Safe Register is the official list of gas engineers legally permitted to work on gas appliances in Great Britain. It replaced CORGI registration in 2009 and is managed on behalf of the Health and Safety Executive (HSE). Any engineer carrying out gas work in Great Britain must be on the Gas Safe Register — this is a legal requirement under the Gas Safety (Installation and Use) Regulations 1998.

Registration is not simply a matter of paying a fee. Engineers must demonstrate competence in the specific appliance categories they wish to be registered for — there are separate competencies for domestic gas, commercial gas, natural gas, LPG, and specific appliance types. The register is independently managed and engineers are subject to periodic assessment to maintain their registration.

When an engineer arrives at your property to carry out gas work, they are legally required to carry a Gas Safe ID card identifying their name, photograph, registration number, and the appliance types they are qualified to work on. You can — and should — ask to see this before allowing any gas work to begin.

You can verify any Advance Plumbing engineer before they begin work by visiting gassaferegister.co.uk or calling 0800 408 5500. Provide the engineer's Gas Safe ID number and the system will confirm their current registration status and the appliance categories they are qualified for.

Our company registration number is 553421. This can also be used to verify Advance Plumbing as a registered business on the Gas Safe Register website.

We actively encourage our clients to carry out this verification. The few minutes it takes to check an engineer's credentials is a worthwhile investment in your safety and peace of mind. Any reputable Gas Safe contractor will welcome this scrutiny — it distinguishes legitimate professionals from unregistered operators.

Gas appliances that are incorrectly installed, poorly maintained, or worked on by unqualified individuals present serious safety risks. Carbon monoxide poisoning — caused by incomplete combustion in faulty gas appliances — kills around 50 people in the UK every year and hospitalises hundreds more. Many of these incidents involve appliances that have been worked on by unregistered individuals.

Beyond safety, there are legal and financial consequences to having gas work carried out by an unregistered engineer. Buildings insurance policies typically exclude damage arising from gas work not carried out by a Gas Safe registered engineer. Mortgage lenders and surveyors will identify non-compliant installations. And when the time comes to sell a property, non-compliant gas work will need to be remediated at the seller's expense.

The cost of using a Gas Safe registered engineer is modest compared to the consequences of not doing so. Advance Plumbing's pricing reflects the cost of properly trained, registered, and insured engineers — not unqualified individuals who can undercut the market precisely because they are not carrying those costs.
