Gas safety certificate cost breakdown
Typical Gas safety certificate costs, by option:
| How many gas appliances | Typical UK cost |
|---|---|
| 1 appliance (e.g. boiler only) | £45 to £70 |
| 2 to 3 appliances | £60 to £100 |
| 4+ appliances or with a boiler service | £90 to £150 |
What's included in the price?
Typical Gas safety certificate prices include:
- A visit from a Gas Safe registered engineer
- A safety check of each gas appliance, such as the boiler, hob and fire
- Checks on gas tightness, operating pressure, flues and ventilation
- The CP12 record (Landlord Gas Safety Record) completed and dated
- A copy for you, and for your tenant if the property is let
What changes the price?
The things that move Gas safety certificate prices most:
The number of gas appliances, the single biggest factor, as each one adds to the fee
Your region, with London and the South East charging the most
Whether you bundle it with a boiler service, which is cheaper than booking both separately
Access and how quickly you need it, as next-day slots cost more
Whether you use a one-off engineer or a landlord cover plan
How the price is built up
The fee covers the engineer's callout and the checks on each appliance, flue and the gas supply, plus completing and issuing the CP12 record. More appliances take longer, so they add to the price. Booking the safety check together with an annual boiler service is usually cheaper than paying for each visit on its own. A gas safety check is a service fee for a Gas Safe registered engineer's time; there are no materials, unless a fault is found and a repair is quoted separately.
Ways to keep the cost down
- Bundle the safety check with an annual boiler service, as one combined visit is cheaper than two
- Book direct with a local Gas Safe registered engineer rather than through a letting agent that adds a markup
- Renew up to two months before the certificate expires without losing the original date, so a delay never leaves you uncovered
- If you let several properties, a landlord cover plan can spread the cost and keep every check on schedule

Common questions
How much does a gas safety certificate cost in 2026?
A gas safety certificate costs about £45 to £150, with most landlords paying around £80. The number of gas appliances drives the price: a single appliance is roughly £45 to £60, a typical home with a boiler and two or three appliances £60 to £100, and more appliances or a check bundled with a boiler service can reach £150. There is no government-fixed price, so engineers set their own fees.
What is a CP12 and who needs one?
A CP12, properly the Landlord Gas Safety Record, is the certificate a Gas Safe registered engineer issues after checking every gas appliance and flue in a property. Landlords in the UK must have one renewed every 12 months and give a copy to tenants. Owner-occupiers are not legally required to have one, but many arrange a check for peace of mind or before selling.
How often does a gas safety certificate need renewing?
Every 12 months for a let property. You can have the check done up to two months before the current certificate expires without losing the original renewal date, which is worth doing so a booking delay never leaves you with a lapsed certificate. For your own home there is no legal interval, though an annual check alongside a boiler service is sensible.
Is a gas safety check the same as a boiler service?
No. A gas safety check confirms your gas appliances are safe to use and produces the CP12 record; a boiler service cleans and maintains the boiler to keep it running efficiently. They are different jobs, but engineers often do both in one visit, and bundling them is usually cheaper than booking each separately. A CP12 on its own does not service your boiler.
What happens if a landlord has no gas safety certificate?
Letting a property without a valid gas safety certificate is a criminal offence enforced by the Health and Safety Executive, with fines and, in serious cases, prosecution. You also cannot use a Section 21 notice to regain possession if you have not given the tenant a valid record. For a rental the £45 to £150 is a legal requirement, not an optional extra.
How can I keep the cost down?
Bundle the safety check with your annual boiler service, since one visit for both is cheaper than two. Book direct with a local Gas Safe registered engineer rather than through a letting agent that adds a markup, and avoid next-day rush slots. If you let several properties, a landlord cover plan can spread the cost and keep the annual checks on schedule.
