What is the Gas Safe Register UK? Simply Explained

Last updated on January 29th, 2024

The Gas Safe Register is the official registration scheme in the UK for gas safety. It was set up to protect the public from unsafe gas work.

The Gas Safe Register UK is for gas engineers who install and maintain gas appliances like boilers, cookers, and fires.

The Gas Safe registration costs nearly £200 per year for a business.

They keep track of all registered engineers and make sure they are competent, and that all of their qualifications are up-to-date. 

gas safety certificate must be carried by someone who is Gas Safe registered.

The Gas Safe Register UK History

The Gas Safe Register took over from CORGI in 2009. It is run on behalf of the Health and Safety Executive (HSE), and any dangerous gas installations must be reported to the HSE.

After a review in 2006, the HSE decided that CORGI needed to change and Capita was appointed to overhaul the scheme and operate it.

Check the Gas Safe Register

From boiler servicing to landlords’ gas safety certificates, getting a Gas Safe registered engineer to carry out work on your gas appliances is important for public safety.

But, also to make sure your gas appliance installations are legal. Make sure you check the Gas Safe Register.

If you can not find a certain company or engineer in their database, they probably do not have the correct qualifications to register, and most likely don’t have the competence to do it safely.

Therefore, they can not carry out any gas work safely or legally.

I would not rely totally on the Gas Safe Register website to tell you if an engineer is registered, as they often have problems which I have experienced first-hand being a registered gas engineer myself.

You should always call the technical helpline to verify if you can’t find confirmation on the website.

Illegal Boiler Installation Problems

If you get a new boiler with a warranty installed by someone who is not Gas Safe registered, then your warranty will be void, and your boiler will probably not have been installed safely.

If you try to make a claim for a boiler repair from the boiler manufacturer, you will not be covered. You will have to pay for the boiler repairs (parts and labour) out of your own pocket.

In this situation, your boiler will have to be removed from the wall and refitted by someone who is Gas Safe registered. This will cost you even more money.

You can not legally pay an engineer to check it over and sign it off, it must be removed, along with any pipework, and refitted.

This is to make sure everything is fitted safely and correctly by someone who is officially trained and registered.


So you might think you were getting a good deal when you got a cheap boiler installation.

But, your new boiler installation cost could go through the roof when you eventually have to pay a registered gas engineer to pull it all and put it right.

What do I do when I smell gas?

If you smell gas, whether it’s a smell of gas from a boiler, the meter, or anywhere else, you should call the gas emergency number.

They will come out and most likely just put a blanking disc in your gas meter, and turn the gas valve handle off.

They will then leave and tell you to call a local gas engineer as they will not try to find the smell inside your home or do anything about it.

Their job is to isolate the gas at the meter if the leak is inside your home, nothing else.

You can turn the gas off yourself if the gas smell is coming from inside the house. You could also call your own, or local, gas engineer straight away if you think he will get there quickly.

Do I need a gas safety certificate when selling my house?

No, you do not need a gas safety certificate or service record when selling your house.

It is recommended you do have one to make sure everything is safe for the new buyers and it might help with their decision to buy the house, but it is not a legal requirement.

How do I check If my boiler is Gas Safe registered?

To check if your boiler is Gas Safe registered, you will need to call the Gas Safe Register technical helpline and ask them.

They will be able to tell you based on the information you give them, typically the address and boiler information.
