Landlord Gas Safety Certificate Cost: What Decides It
Landlords often ask what a gas safety certificate costs before anything else. The honest answer depends on the property, so this guide explains what changes the price and how to avoid paying for the same visit twice.

What you are paying for
A landlord gas safety record, often called a CP12, is the written result of a safety check on each gas appliance, fitting and flue you provide to tenants. A Gas Safe registered engineer has to do the check every year, and the tenant has to receive a copy. The cost covers the engineer's time on site, the testing and the paperwork.
It is a safety inspection, not a service. The engineer checks that appliances burn and vent safely, but does not strip down and clean the boiler unless a service has been booked too.
The things that change the price
The main factors are:
How many gas appliances there are: a boiler only, or a boiler plus a hob, fire or cooker
Whether the boiler service is done on the same visit
How easy it is to reach the appliances, meter and flue, including flues in voids
Whether several properties are booked together
Whether anything fails and needs remedial work
Combining the check with a boiler service
Many landlords book the gas safety check and the annual boiler service together. It means one visit, one arrangement with the tenant and a boiler that has been looked at properly, not just tested. Ask about this when booking; our boiler service cost guide explains what a full service adds on top of the safety check.
If an appliance fails
If an appliance is unsafe, the engineer will explain why and follow the industry procedure, which can mean turning it off or disconnecting it until it is fixed. The repair is a separate job from the certificate and is priced on its own.
Failures are more common where appliances have not been serviced, flues are hard to inspect or ventilation has been blocked. Keeping on top of servicing tends to make the annual check quicker and cheaper over time.
Avoiding wasted visits
A missed appointment is the most avoidable extra cost. Book a few weeks before the old record runs out, give the tenant plenty of notice, and make sure the engineer can reach the meter and every appliance. If you have several properties in the area, booking them together can make the day work better for everyone.
Comparing quotes fairly
When you compare prices, check exactly what each one includes. Does it cover every gas appliance in the property, or only the boiler? Is a boiler service included or extra? Will the record be sent to you, and how? Knowing that up front means you are comparing the same job, not just the headline number.

Common questions
Gas safety certificate cost FAQs
Clear answers before you arrange a visit.
How much does a landlord gas safety certificate cost?+
It depends mainly on the number of appliances, access and whether a boiler service is done at the same time. Contact us with the details and we will quote.
How much should a gas safety certificate cost?+
Compare like for like: check whether a quote covers every appliance, includes a service, and what happens if something fails. The cheapest headline figure is not always the best value.
Does the price include fixing anything that fails?+
No. Remedial work is quoted separately once the engineer has explained what is needed.
Do homeowners need a gas safety certificate?+
There is no legal requirement for owner-occupiers, but a safety check can give peace of mind, especially after moving into a new home.
Can the gas safety check and boiler service be done on the same day?+
Yes. Many landlords book both together so the tenant only has to give access once. Mention it when booking so enough time is allowed for both jobs.
