About Gas Safe Register

Please see our list of frequently asked questions about Gas Safe Register. We have put together some information for you to read regarding Gas Safe register and various information about health and safety. If you cannot find the answer to your question, please use the menu tabs below to get in touch with us.

What is Gas Safe Register

Gas Safe Register is the official gas registration body for the United Kingdom, Isle of Man, Guernsey and Jersey. It replaced CORGI registration and by law all gas engineers must be on the Gas Safe Register. Our role is to act as a licensing body.

What is the purpose of Gas Safe Register?

The register (and all services associated with it) is operated on behalf of the relevant Health and Safety Authority for each region in which it operates – i.e. Great Britain, Northern Ireland, Isle of Man, Guernsey and Jersey. As part of this we also investigate reports of illegal and unsafe gas work. When we investigate these cases the information we gather is passed on to the relevant authority which has the power to prosecute.

In addition, we run public awareness campaigns to make the public aware of the risks of unsafe and illegal gas work and highlight dangers such as carbon monoxide (CO) poisoning. We also co-ordinate the industry-wide Gas Safety Week campaign. This runs each year and brings together organisations across the UK to raise awareness of the importance of safe and legal gas work.

How do I check you are Gas Safe registered?

You will find our current seven-digit licence number. This can be found on our Gas Safe ID card, which will be shown to you if requested.

What is the difference between the business registration number and the engineers licence card number?

The Gas Safe Register is a list of businesses that are legally permitted to carry out gas work under the trading name that they have registered with. Each business is issued with a registration number when they are entered onto the register.

Within each business there will be one or more gas engineers, each of whom will be issued with their own Gas Safe ID card. This card confirms their registration with us and the work they are qualified to carry out.

Can all gas engineers work on all types of gas appliances?

In short: no. All Gas Safe registered engineers will have a list of the work they are qualified to carry out on the back of their Gas Safe ID card. The minimum qualification is ‘Pipework’ however gas engineers will usually be qualified for a range of gas work.

It’s important to check they are qualified to do the work you need before you use them.

Engineers will have different qualifications, including:

  • Domestic (homes) and commercial (businesses and factories)
  • LPG and natural gas
  • Different areas of gas work e.g. boilers, cookers, fires etc.

The engineer’s unique licence number, found on the front of their Gas Safe ID card, allows you to check their current qualifications online using our ‘check an engineer’ function.

How do I report someone working illegally?

If you suspect someone is working on gas appliances without being Gas Safe registered please gather as much information as you can e.g. names, dates and address of where gas work was done and we will investigate. The more information you have the more effective our investigation can be.

You can report an illegal gas worker online using our form. You can also call our Customer Services team on 0800 408 5500.

What is the difference between a gas safety check and a service?

A gas safety check assesses the basic safety of gas appliances in your home. Its purpose is to ensure everything is working correctly and is safe.

A safety check includes, but is not limited to:

  • Checking gas appliances are burning correctly with the correct operating pressure
  • Checking harmful gases are being removed from the appliance safely to the air outside
  • Checking ventilation routes are clear and adequate
  • Checking any safety devices are working properly

A service will consist of a full check of a gas appliance and alongside the checks listed above they will:

  • Follow the manufacturer’s instructions and carry out equipment specific actions such as:
    • The removal of components for cleaning
    • The replacement of serviceable parts such as seals/gaskets
    • Cleaning of the heat exchanger and any flueways
  • Assess the physical condition of the appliance
  • Check the state of any air vents and any flues to ensure they have not deteriorated
  • Carry out combustion performance tests (where applicable) to confirm the safe and efficient operation of the appliance
  • Undertake any necessary remedial work (your engineer will inform you of any additional costs)
  • Alert you to any issues found during the service

For more information on this you can visit our ‘Get your appliances checked’ guidance.
