If you’re a landlord or homeowner in the UK, staying on top of gas safety isn’t just good practice – it’s a legal requirement. One key part of that is having a valid gas safety certificate, also known as a CP12. But how much does a gas safety certificate cost? Let’s break it down simply, without the fluff.
What Is a Gas Safety Certificate?
A gas safety certificate is a document issued by a Gas Safe registered engineer after they’ve inspected your gas appliances, pipework, and flues. It confirms everything is working as it should be and poses no safety risk.
This inspection is mandatory for landlords every 12 months. Homeowners aren’t legally required to get one, but it’s still highly recommended – especially if you’re selling your property or want peace of mind.

Gas Safety Certificate Cost – What Should You Expect to Pay?
The cost of a gas safety certificate in the UK varies depending on a few things:
Your location – Prices in London or the South East tend to be higher.
Number of appliances – The more gas appliances (like boilers, cookers, or gas fires), the more time the inspection takes.
Type of property – A large house might cost more than a small flat due to extra checks.
Average Prices:
One appliance (usually just a boiler) – Around £85 to £120
Two to three appliances – Typically £95 to £150
Larger properties or multiple units – Can go up to £150+
These are general figures. Some engineers might charge less, especially if you’re booking additional services at the same time, such as a boiler service or annual maintenance check.
Can You Get a Gas Safety Certificate for Free?
Not usually. It’s a professional service and must be done by a Gas Safe engineer, which means there’s a cost involved. However, some letting agents or property management services include it in their landlord packages, so it’s worth checking if you’re covered.
Tips for Keeping Costs Down
- Shop around – Get quotes from a few Gas Safe engineers in your area.
- Bundle services – Combine the gas safety check with your boiler service.
- Ask about landlord packages – Some offer annual checks at a discounted rate.
What Happens If You Don’t Get One?
For landlords, skipping a gas safety certificate is a serious offence. You could face:
- Fines of up to £6,000
- Invalid insurance
- Legal action if a tenant is harmed
So it’s not just about ticking a box – it’s about protecting lives and staying on the right side of the law.
How to Find a Qualified Engineer
Always use a Gas Safe registered engineer. You can check the official register at GasSafeRegister.co.uk. Don’t be tempted by cheap offers from unregistered individuals – it’s not worth the risk.
The Bottom Line
The gas safety certificate cost in the UK usually sits between £85 and £120, depending on the property and number of appliances. It’s a small price to pay for safety, compliance, and peace of mind. Whether you’re a landlord needing it by law or a homeowner wanting to keep things in check, it’s worth budgeting for each year.

FAQs
The cost usually depends on the number of gas appliances in your property, your location, and whether you combine it with other services like a boiler service. Engineers in areas like London may charge more due to higher operating costs.

For landlords, it’s a legal requirement to renew every 12 months. Failing to do so can lead to fines, insurance issues, and even criminal charges. Homeowners aren’t legally obliged, but it’s still strongly advised for safety.
Yes. If you’ve had a new boiler or appliance installed, the engineer should provide a gas safety record or commissioning certificate. A CP12 certificate can also be issued if you request a full safety inspection.
