Also known as the CP12 Certificate, this statutory check must be carried out by a qualified professional. A specialist engineer can inspect your gas appliances, fittings and chimneys to ensure they meet legal standards, as stipulated in the Gas Safety (Installation and Use) Regulations 1998.
To give you an idea of costs ahead of hiring a professional, we’ve put together the following pricing guide to obtaining a CP12 Certificate.
Cost provided item | Unit | Cost +VAT (Range Low) | Cost +VAT (Range High) | Average UK Cost |

How much does a gas safety certificate cost?
The average cost of a gas safety certificate in the UK ranges between £60 – £90. We recommend budgeting at least £80 for this check. Do also consider that this price range is typically for a property that has one boiler, one gas hob or fireplace to check. Additional gas appliances are typically charged at £10 each.
Other factors that will affect the quotes you receive from engineers include location, with prices in London inevitably higher.
A quick cost-saving tip for landlords
You could save on cost by ‘lumping’ products together, e.g. using a rental agent who includes the cost of a gas certificate in their management fee. You may even wish to have your boiler serviced at the same time as the gas safety check.
Do I need a gas safety certificate?
All UK landlords are required by law to have a registered Gas Safe Engineer check their gas appliances for health and safety.
It’s worth noting that you can only obtain a gas safety certificate if the work is carried out by a registered Gas Safe engineer. In other words, this isn’t a task you can do yourself to save costs.
How often do I legally need a gas safety certificate?
Gas appliance fittings, chimneys, flues and pipework should be checked every year to ensure maximum safety for your tenants.
If your rental property is overdue for an inspection, make it a priority to call a professional and arrange a check.
Do I need a gas safety certificate to sell my home?
Homeowners aren’t responsible for obtaining a gas safety certificate when selling their property. However, as a landlord, you are liable for the safety of your tenants. When selling your rental property, you must have physical records to show that gas safety checks have been carried out annually.
How can I get a gas safety certificate?
You can get a gas safety certificate by making an appointment with a Gas Safe engineer. Once the inspection is complete, providing appliances are deemed safe, you will receive your CP12 Certificate. You will need to provide a copy to your tenants within 28 days and store a copy for your own records.
Which appliances need to be checked?
A Gas Safe engineer will inspect all gas appliances including boilers, cookers, fires (portable or permanent). They will also inspect pipework, fittings, chimneys and flues to ensure safety and efficiency.
If you are aware that a key appliance, such as your boiler, may need servicing you and want to know the total boiler service and gas safety certificate cost, then take a look at our boiler service cost guide and add this cost into your calculation.
Factors affecting gas safety certificate cost
As well as location, the key factor affecting the total cost of a gas safety certificate will be the number of gas appliances that need to be checked. While you won’t be responsible for any gas appliances that the tenant has purchased separately, you are responsible for the pipework that supplies the appliances with gas. For that reason, it’s best to include all gas appliances in your inspection.
Keep in mind that any electrical appliances supplied with the property will also need an inspection before tenants move in. As with gas appliances, a qualified electricity safe engineer will need to undertake this statutory check separately, so it’s worth factoring this into your budget.
Gas safety certificate cost calculator
To calculate the cost of obtaining a gas safety certificate, the three main factors that will affect the price you pay are:
- The size and condition of your property
- Where you live in the country
- The individual gas engineer you hire
Your gas inspection must be carried out by a registered Gas Safe engineer, but individuals will charge different rates for their services. You can expect to pay a higher price for gas engineers in and around London.

We always recommend obtaining at least three quotes from our trusted tradespeople. With gas safety certificates, there tends to be a fairly small range when it comes to costs – due to gas inspections generally being fairly standard.
