Gas safety certificate for homeowners
Owner-occupiers are not legally required to have a gas safety certificate. Here is when a check still makes sense, and how it differs from a boiler service.

Is it a legal requirement?
The yearly gas safety record is a legal duty for landlords. If you live in your own home, there is no legal requirement to have a certificate, but you are still responsible for keeping your appliances safe.
Why homeowners still book one
- You want to know the boiler, cooker, hob and flues are safe
- You are buying or selling and want a record to show
- A mortgage lender, insurer or solicitor has asked for evidence
- You have inherited or moved into a property and do not know its history
- You have a gas hob or cooker that has never been checked
Check, service or both?
A gas safety check records whether appliances are safe to use. A boiler service is maintenance to the manufacturer’s instructions, and keeps most warranties valid. They are not the same, and neither includes repairs. See service versus safety check, or ask for both together on boiler service and gas safety.
Cost
£92.50 for up to two appliances, plus £22.50 for each additional appliance. Gas fires are charged separately.
A boiler service is from £92.50.
Carbon monoxide alarm
A working carbon monoxide alarm is recommended wherever there is a fuel-burning appliance. It does not replace a gas safety check or servicing. If your alarm sounds, stop using the appliance, get into fresh air and call the National Gas Emergency Service on 0800 111 999.
Common questions
Do I need a gas safety certificate to sell my house?
Not legally. See gas safety certificates when selling a house.
Does home insurance require one?
Policies differ. Check your policy wording or ask your insurer.
How often should I have my gas appliances checked?
Annually is sensible, and most manufacturers require a yearly service to keep the warranty valid.
