Gas Safe vs CORGI: What Certification to Look For

By The FixDelivered Team · Updated 2026-09-06 · 5 min read

When it comes to gas appliances and installations in your home, safety is paramount. For years, many UK homeowners associated gas safety with CORGI. However, since 2009, the landscape has changed significantly. It's now crucial to understand the difference between CORGI and the Gas Safe Register – the only official body for gas engineers in the UK.

Understanding Gas Safety: From CORGI to Gas Safe

For over 30 years, CORGI (Council for Registered Gas Installers) was the UK's voluntary gas registration body. From 1998, it became the statutory body, meaning all gas installers had to be CORGI registered by law. The CORGI scheme aimed to ensure that gas work was carried out by competent individuals, thereby reducing the risks associated with faulty gas installations, such as carbon monoxide poisoning, fires, and explosions.

However, in 2009, the Health and Safety Executive (HSE) decided to replace CORGI with a new, enhanced registration scheme to further improve gas safety standards across Great Britain and the Isle of Man. This change was implemented to provide a more robust and transparent system for both engineers and the public.

The Gas Safe Register: Your Assurance of Safety

The Gas Safe Register is the official gas registration body for the United Kingdom, Isle of Man, Guernsey, and Jersey. It replaced CORGI on 1st April 2009. By law, all gas engineers must be on the Gas Safe Register to work legally on gas appliances. This includes everything from boilers and cookers to gas fires and pipework.

The primary role of the Gas Safe Register is to protect the public from unsafe gas work. It achieves this by ensuring that all registered engineers are qualified and competent to work safely and legally. The register maintains a list of over 120,000 qualified gas engineers and carries out regular inspections to ensure standards are upheld. Each Gas Safe registered engineer carries an ID card with their unique licence number, which consumers can verify.

Why the Switch from CORGI to Gas Safe?

The move from CORGI to the Gas Safe Register was driven by a need for greater oversight and enforcement within the gas industry. While CORGI served an important purpose, the HSE identified areas for improvement, particularly concerning the monitoring of unregistered gas fitters and the effectiveness of enforcement actions. The Gas Safe Register was designed to be more rigorous, with stronger regulatory powers and a clearer focus on public safety.

Key improvements included enhanced auditing of engineers, a more robust complaints procedure, and a dedicated team to investigate illegal gas work. This transition was not just a name change; it represented a significant step forward in ensuring the competence and accountability of gas engineers across the country.

How to Verify a Gas Safe Engineer

It is absolutely critical to verify an engineer's Gas Safe registration before allowing them to carry out any gas work in your home. This is straightforward and can be done in two main ways:

Check their ID Card: Every Gas Safe registered engineer carries a Gas Safe ID card. This card features their photo, a unique licence number, the start and expiry dates of their registration, and a list of the types of gas work they are qualified to undertake (e.g., boilers, cookers, fires). Always ask to see this card.
Check Online or by Phone: You can verify an engineer's details or check if a business is registered by visiting the official Gas Safe Register website or calling them directly. You’ll need the engineer’s licence number from their ID card, or the company’s registration number.

Never proceed with gas work if an engineer cannot provide valid Gas Safe identification. If you're looking for a qualified professional, you can find Gas Safe registered plumbers through services like FixDelivered, ensuring peace of mind.

The Dangers of Unregistered Gas Work

The risks associated with using an unregistered or unqualified individual for gas work are severe and potentially fatal. Unsafe gas work can lead to:

Carbon Monoxide Poisoning: Often called the 'silent killer' because it's odourless, colourless, and tasteless. Faulty gas appliances can produce carbon monoxide, leading to severe illness or death.
Gas Leaks: Leading to explosions or fires, posing an immediate danger to life and property.
Damage to Appliances: Incorrect installation or servicing can damage your gas appliances, rendering them inefficient or unsafe.
Legal Implications: If you are a landlord, it is a legal requirement to have annual gas safety checks carried out by a Gas Safe registered engineer. Failure to do so can result in significant fines or even imprisonment.

Always prioritise safety over cost. The potential consequences of cutting corners on gas work are simply not worth the risk.

Beyond Gas: What About Other Plumbing Work?

While Gas Safe registration is exclusively for gas work, it's important to remember that not all plumbing tasks require this specific certification. For general plumbing issues like dripping taps, burst pipes, or toilet repairs, an engineer doesn't need to be Gas Safe registered unless the work involves a gas appliance or its pipework. However, it's still advisable to use a qualified and reputable plumber for all your home's plumbing needs to ensure quality workmanship and safety.
