Keeping your home warm and your gas appliances safe isn’t just a good idea – it’s the law. If you’re a homeowner or landlord in the UK, you’ve likely heard about the importance of an annual boiler service and holding a valid Gas Safety Certificate. But how much should all of this actually cost? And what exactly are you paying for?
We’ve broken it down simply below, with no jargon – just clear info you can use.
What Is a Boiler Service?
A boiler service is a routine check carried out by a Gas Safe registered engineer to make sure your boiler is working safely and efficiently. It’s recommended once a year, and in many cases, it’s required to keep your manufacturer’s warranty valid.
During a standard service, the engineer will:
- Check for gas leaks
- Inspect the flue and ventilation
- Test the pressure and controls
- Clean parts if needed
- Highlight any signs of wear or damage
Regular servicing not only helps avoid costly breakdowns but can also keep your energy bills lower by improving efficiency.

What Is a Gas Safety Certificate?
A Gas Safety Certificate (also called a CP12 certificate) is a legal requirement for landlords across the UK. It confirms that all gas appliances in a rented property – such as the boiler, cooker, and gas fire – have been checked and are safe to use.
Landlords must:
- Have a gas safety check carried out annually
- Keep a copy of the certificate for at least two years
- Give tenants a copy within 28 days of the inspection
If you’re a homeowner, you’re not legally required to have one – but it’s still wise to get your gas appliances checked yearly as part of a boiler service.
How Much Does a Boiler Service and Gas Safety Certificate Cost in the UK?
Prices can vary depending on where you live, the type of boiler, and whether you’re combining services. But here’s a general idea:
Boiler service only: £120 to £250
Gas Safety Certificate only (CP12): £85 to £250
Combined service and certificate: from around £120 to £350
Booking both together often works out cheaper than having them done separately. Some local engineers and companies also offer fixed-price packages, which can be handy for budgeting.
Factors That Can Affect the Cost
A few things can push the price up or down:
- Your location: Prices tend to be higher in London and the South East.
- The number of appliances: If you need multiple gas checks, it’ll cost more.
- Boiler type and condition: Older or less common boilers may take more time to service.
- Urgency: Same-day or out-of-hours visits might come with an extra fee.
Is It Worth It?
Absolutely. Whether you’re a homeowner trying to avoid boiler issues or a landlord staying on the right side of the law, regular servicing is worth every penny. It can save you hundreds in repair bills, keep your tenants safe, and give you peace of mind – especially in winter.

The Bottom Line
In short, the boiler service and gas safety certificate cost in the UK doesn’t have to break the bank – especially if you combine both jobs in one visit. And more importantly, keeping on top of these checks helps protect your home, your wallet, and your loved ones.
