Landlord gas safety certificate: cost and rules for 2026
Every UK landlord with a gas appliance needs a gas safety check every 12 months. Here is what it covers, what it typically costs, and the dates that catch people out.
If your rental property has a gas boiler, fire, hob or any other gas appliance you provide, you're legally required to have it checked every year. This is one of the few landlord duties where the law is identical across England, Scotland and Wales, and one of the most strictly enforced.
What the gas safety check covers
The engineer checks every gas appliance, fitting and flue you supply. That includes:
- Testing that appliances burn correctly and are set to the right gas pressure.
- Checking flues and chimneys clear combustion gases safely.
- Checking there's an adequate supply of air for each appliance.
- Testing safety devices are working.
- Recording any defects and any action taken, including disconnecting a dangerous appliance.
A gas safety check isn't the same as a boiler service. The check confirms the appliance is safe today, while a service maintains it so it keeps running efficiently. Most manufacturers want an annual service to keep the warranty valid, and many engineers will do both in one visit.
How much does a gas safety certificate cost in 2026?
Prices vary by region and by how many appliances the engineer has to test. As a rough guide for 2026:
| What's being checked | Typical price |
|---|---|
| Boiler only | £50 to £80 |
| Boiler plus hob or fire | £60 to £100 |
| Each additional appliance | £10 to £20 |
| Gas safety check plus boiler service | £90 to £150 |
These are typical market ranges, not fixed prices. London, rural areas and urgent call-outs cost more. If you have several properties, ask for a multi-property rate and keep all the renewal dates in one calendar.
The timing rule that saves you money
Since 2018 you can have the check done up to two months before the current record expires and keep the original expiry date. A check due on 1 December can be done any time from 1 October, and the next one is still due by 1 December the following year. Booking early costs you nothing and gives you room if an engineer cancels. Not sure when yours is due? Use our free compliance deadline checker.
Access when a tenant won't let the engineer in
You must take "all reasonable steps" to carry out the check. If a tenant refuses access, keep a written record of every attempt: letters, emails and missed appointments. Give proper notice each time. That evidence is what protects you if the record lapses through no fault of yours.
Penalties for missing a gas safety check
Failing to keep a valid gas safety record is a criminal offence, enforced by the Health and Safety Executive. Courts can impose unlimited fines and, in serious cases, prison sentences. Insurers may also refuse claims, and a lapsed record is the kind of thing a tenant, council or tribunal will look at first if anything goes wrong.
Related safety duties
- Carbon monoxide alarms: in England, required in every room with a fixed combustion appliance (gas cookers excepted). In Scotland, required wherever there is a carbon-fuelled appliance or a flue.
- Electrical safety: a separate EICR is needed at least every five years. See our compliance checklist.
Frequently asked questions
How much does a landlord gas safety certificate cost?
Most landlords pay somewhere around £60 to £100 for a check covering a boiler and one other appliance, such as a hob. Each extra appliance usually adds a small amount, and prices are higher in London and for same-day call-outs. Bundling the check with a boiler service often saves money.
How often do landlords need a gas safety check?
At least once every 12 months. The check can be done up to two months before the current record expires while keeping the original renewal date, so you never lose time by booking early.
When must tenants receive the gas safety record?
Existing tenants must get a copy within 28 days of the check. New tenants must get a copy before they move in. Keep each record for at least two years.
Is a CP12 the same as a gas safety certificate?
Yes. "CP12" was the old CORGI form name and is still widely used for the landlord gas safety record. Any record that contains the legally required information is valid.
Does the landlord gas safety check cover tenants’ own appliances?
No. The landlord is responsible for the gas appliances, pipework and flues they provide. A tenant’s own cooker is not covered, although the pipework and any flue serving it still are.
