Gas Safe vs CORGI: What Certification to Look For

By The FixDelivered Team · Updated 2026-08-06 · 5 min read

When it comes to gas appliances in your home, safety is paramount. Choosing the right professional to install, service, or repair them isn't just about competence; it's a legal requirement and a matter of life and death. For years, the public looked for CORGI registration, but that changed over a decade ago. Now, it's all about the Gas Safe Register. Understanding this distinction is crucial for every UK homeowner.

What Was CORGI?

CORGI (Council for Registered Gas Installers) was the official registration body for gas installers in the UK from 1970 until 2009. If you needed work done on your boiler, gas cooker, or any other gas appliance, you would typically look for a CORGI registered engineer. The scheme aimed to ensure that gas engineers were competent and worked to a recognised standard, thereby protecting the public from unsafe gas work.

However, over time, the government decided that a new, more robust, and independently regulated scheme was needed to enhance public safety. This led to the transition from CORGI to the Gas Safe Register.

What is the Gas Safe Register?

The Gas Safe Register is the official gas registration body for the UK, Isle of Man, and Guernsey. It replaced CORGI on 1st April 2009. Its primary purpose is to protect the public from unsafe gas work. By law, every gas engineer carrying out work on gas appliances must be on the Gas Safe Register.

Unlike CORGI, which was a commercial company, the Gas Safe Register is an independent, non-profit organisation appointed by the Health and Safety Executive (HSE). This independence helps ensure that the focus remains squarely on safety and maintaining high standards across the gas industry.

What Does it Mean to be Gas Safe Registered?

An engineer registered with Gas Safe has demonstrated their competence and qualifications to work safely and legally on specific types of gas appliances. They undergo regular assessments and checks to ensure they continue to meet these stringent standards. This covers a wide range of gas work, including:

• Installing, repairing, and servicing gas boilers
• Installing and repairing gas fires
• Working on gas cookers and hobs
• Checking and installing gas meters
• Landlord Gas Safety Checks

Crucially, a Gas Safe registered engineer will carry a Gas Safe ID card. This card shows their unique registration number, expiry date, and the specific types of gas work they are qualified to undertake (e.g., natural gas, LPG, domestic, commercial, boilers, cookers). Always ask to see this card before any work begins.

Why the Change from CORGI to Gas Safe?

The transition from CORGI to the Gas Safe Register was primarily driven by a government initiative to improve gas safety standards and public protection. The HSE wanted a more independent and robust system to oversee gas engineers. The Gas Safe Register was established with a stronger emphasis on enforcement, public awareness, and a clear, easily verifiable registration system.

This change has provided a clearer, more consistent benchmark for competence and safety, giving consumers greater confidence when hiring someone to work on their gas appliances.

The Dangers of Unregistered Gas Work

Using an unregistered or unqualified individual for gas work is incredibly dangerous and illegal. The consequences can be severe, including:

• Carbon Monoxide Poisoning: Often called the 'silent killer', carbon monoxide is a colourless, odourless gas that can be produced by faulty or poorly installed gas appliances. Symptoms include headaches, nausea, dizziness, breathlessness, collapse, and loss of consciousness, leading to death.
• Gas Leaks: Improperly installed or maintained gas pipework can lead to dangerous gas leaks, which pose a significant risk of fire and explosions.
• Fires and Explosions: Unsafe gas appliances can ignite, causing devastating fires or even explosions that can destroy property and cause serious injury or death.
• Legal Implications: As a homeowner, you have a responsibility to ensure any gas work carried out in your property is done by a Gas Safe registered engineer. Using an unregistered individual could invalidate your home insurance and potentially lead to legal issues if an incident occurs. Landlords, in particular, face severe penalties for non-compliance with gas safety regulations.

How to Check if an Engineer is Gas Safe Registered

Verifying an engineer's registration is simple and essential:

1. Ask to see their ID card: Every Gas Safe registered engineer carries a Gas Safe ID card. Check the front for their photograph, the start and expiry dates, and the security hologram.
2. Check the back of the card: Crucially, the back of the card lists the types of gas work the engineer is qualified to do (e.g., central heating boilers, cookers, fires). Ensure the work you need done is listed.
3. Use the Gas Safe Register website: You can enter the engineer's registration number (from their card) or their business name on the official Gas Safe Register website to verify their credentials.
4. Call the Gas Safe Register: If you're unsure or can't access the website, you can call the Gas Safe Register directly to confirm.
