Gas safety certificate cost guide

Under the Gas Safety (Installation and Use) Regulations 1998, a Gas Safety Certificate is a mandatory requirement for landlords in ensuring the safety of their tenants. So, if you own rental property in the UK, obtaining one of these is a top priority.

But how much does a gas safety certificate cost?

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.

To give you an idea on costs ahead of hiring a professional, we’ve put together the following pricing guide to obtaining a CP12 Certificate.

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 budgting at least £80 for this check. Naturally, factors such as location will influence the quote you receive from engineers, with prices in London inevitably skewing higher.

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 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.

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 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.
