How Much is a Gas Safety Certificate?
The average gas certificate cost in the UK is around £75.
This fee is based mainly on the labour cost of a gas safety check. This means that the prices you're quoted by local tradesmen will depend on where you're located in the UK.
Gas safety certificates are a legal requirement for any UK landlord. These statutory checks must be carried out by an approved Gas Safe engineer every year.

How Do You Get a Gas Safety Certificate?
It's your responsibility as a landlord to get a gas safety check each year.
You can only obtain a Landlord’s Gas Safety Certificate if the work is carried out by a registered Gas Safe engineer, so make sure that the engineer that you employ is qualified to carry out the work.
It is advisable to use the Gas Safe Register to find your Gas Safe engineer so that you can be sure that your engineer is officially approved to undertake the inspection. Visit the Gas Safe Register's Find An Engineer page.
It is wise to consult a number of Gas Safe engineers before you make a decision, because you will find that the cost that you are quoted for the work will vary.
There are Gas Safe engineers who will carry out the work from as little as £35, whilst others may charge as much as £150. Costs across the country will also vary from place to place, so it is best to get a selection of quotes before you make a decision.
What Does a Gas Safety Check Involve?
The inspection must include all gas appliances, pipework, chimneys and flues in the property.
For many nowadays, there are fewer gas appliance, so for many, they may only require their gas fire servicing. If you are not aware of which appliances use gas, a Gas Safe Engineer can tell you which are, during their inspection.
When your Gas Safe engineer arrives, they will undertake the following checks on your gas appliances:
- Each appliance for gas tightness.
- The standing and working gas pressure (if test points are available).
- The burner pressure/gas pressure against the manufacturer's plate.
- That the provision of all necessary ventilation is satisfactory.
- The flue flow to ensure the removal of products of combustion.
- That safety devices work properly.
- For any misuse of gas devices or terms.
Although you are not responsible for any gas appliances that your tenant may have brought to the property themselves, it is a good idea to include them in the inspection. You are not responsible for the appliances that they have brought with them, but you are responsible for the pipework that supplies the gas to those appliances.
Once you pass the check you will receive your Landlord’s Gas Safety Certificate (CP12). This certificate is valid for one year. You will need to undertake this check every year.
You must pass a copy of the CP12 to your tenants within 28 days of issue. When new tenants move in, you will need to give them a copy.
What Happens If the Gas Safety Check Finds Issues?
If the check finds problems with gas safety in the property, these problems will need to be rectified. It's important to note that any extra work will not be covered within your gas safety certificate cost.
There are a few things to be aware of:
- The results of the check will be issued immediately (before any defects are fixed).
- The record of the gas safety check is a 'living document', so updates can and should be added to it.
- Any remedial action taken after the check should be added to the record.
If action needs to be taken, your gas engineer will explain what should be done and why.
It's a landlord's responsibility to ensure the property's gas supply is completely safe. Ignoring immediate issues or recommended improvements could invalidate your landlord's insurance or even result in civil or legal penalties if something goes wrong.
Repairs and Maintenance
There are various repairs or maintenance activities your Gas Safe engineer may recommend following your gas safety check.
Examples include:
- New Boiler - A boiler that is deemed unsafe may have to be immediately replaced. The cost of a new boiler installation will depend on various factors such as size, but you'll usually pay between £2,000 and £3,000.
- Removing a Gas Fire - If there is a gas fire in the property that isn't used, it may be best to just remove it. The typical cost to remove a gas fire is between £60 and £90, but there are higher costs if you want to remove the hearth or the chimney stack at the same time.
- Install New Radiators - If a radiator isn't working correctly, you might be advised to replace it. On average, the cost to replace a radiator is around £200.
Heating engineer prices will depend on the type of job and where you're located in the UK.
As with your gas safety check, be sure to get quotes from multiple tradesmen before committing to any gas repairs or maintenance.
