Compare prices for your propertyWhat changes the price
Number of appliances
Each gas appliance - boiler, hob or cooker, gas fire - is checked and recorded, so more appliances means a higher price.
Flues and chimneys
The engineer checks that each appliance is venting safely. Open flues and chimneys take longer than a modern room-sealed boiler.
Access
Boilers in lofts or cupboards full of belongings take longer to reach. Let your tenant know so the engineer can get to every appliance.
Commercial properties
Shops, offices and other commercial premises are priced separately from homes.
Add a boiler service to the same visit
A gas safety check is not a boiler service: the check makes sure appliances are safe, while a service keeps the boiler working well. Many Gas Safe engineers on RentalComply offer both, so you can book them together and save a second visit.
If an appliance fails the check
The engineer records any defects on the certificate. An appliance that is unsafe may be turned off or disconnected until it is repaired, and the repair is priced separately from the check.
Never pay for a rushed renewal
Add your property to RentalComply and we'll remind you before each certificate expires, so you can book in good time. Your first property is tracked free.
Gas Safety cost: common questions
How much does a landlord gas safety certificate cost?
On RentalComply, gas safety checks currently cost from £81.25 for 1 appliance up to £125 for 4+ appliances, from 2 Gas Safe registered engineers. Each engineer sets a fixed price by number of appliances, so you see the full price before you book.
What counts as a gas appliance?
Anything that burns gas: the boiler, a gas hob or cooker, and any gas fires. Appliances your tenant owns are not part of your duty, but the pipework and any flues you provide are.
How often do I need a gas safety certificate?
Every 12 months, under the Gas Safety (Installation and Use) Regulations 1998. You can have the check done up to two months before the due date and keep the original renewal date.
What is a CP12?
CP12 is the old name for the landlord gas safety record. It is the same certificate - give a copy to existing tenants within 28 days of the check and to new tenants before they move in, and keep records for at least two years.
Can I charge my tenant for the gas safety check?
No. In England the Tenant Fees Act 2019 stops landlords charging tenants for safety checks - the gas safety certificate is the landlord's cost.
Does the price include a boiler service?
No - they are different jobs. Many engineers offer a boiler service at the same visit for an extra fixed price.
