If you want to keep your boiler running safely and efficiently, regular servicing is a must. However, for many homeowners, the cost of a boiler service can feel like a mystery. With so many companies and options out there, it’s easy to be unsure about what you should expect to pay, what’s included, and how to make the best decision for your home. In this guide, we break down the average costs for 2025, look at what you get for your money, and offer tips to help you get the most value (and peace of mind) from your boiler service.

The Current Average Cost of a Boiler Service

In 2025, the average cost of a standard boiler service in the UK ranges from £80 to £120 for most homeowners. This covers routine servicing for gas boilers, which are the most common type in British homes. Prices can be a bit lower for basic checks, or higher if you have an oil or LPG boiler, live in certain areas, or choose a premium service with extras.

Some things that affect price include:

• Location: Prices can vary depending on where you live, with some areas seeing higher average costs due to demand or travel distances for engineers.
• Boiler type: Oil and LPG boiler servicing tend to cost more than gas models due to specialist checks and parts.
• Age and condition: Older or less well-maintained boilers may need more time and work, increasing the overall bill.

Typically, you should expect to pay somewhere in the middle of this range for a straightforward, routine service carried out by a qualified professional.

What’s Included in a Boiler Service?

A standard boiler service usually involves a thorough inspection and clean of your boiler and its components. Here’s what a typical service includes:

• Full safety checks, including testing for gas or oil leaks.
• Visual inspection of the boiler and associated parts.
• Cleaning internal components to remove dirt and debris.
• Testing controls to ensure the system operates as it should.
• Checking the flue and ventilation for blockages or problems.
• Recording emission levels, ensuring the boiler is burning fuel efficiently.
• Advice or reporting on any issues or repairs required.

If you book with a Gas Safe registered company, you can count on a proper service every time. For those in Lincolnshire, for example, regular boiler service Spalding visits mean your appliance is safe, efficient, and less likely
to break down unexpectedly.

How Much Should Boiler Maintenance Cost?

Beyond the annual service, maintenance may involve small fixes or preventative work throughout the year. Minor jobs like repressurising the boiler or topping up inhibitor can be included in some boiler service plans or charged as extras (usually £10–£50 depending on complexity).

Emergency repairs or parts replacement will naturally cost more, typically depending on what’s required. Keeping up with annual servicing is the best way to avoid larger bills in the future, as regular checks catch issues early before they grow into expensive problems.

If you want to spread out the cost, consider a Spalding boiler service plan. Many plans include annual servicing, priority breakdown visits, and discounts on parts for a set monthly fee, making budgeting easier and your home’s heating more reliable.

What Does British Gas Charge for Boiler Service?

British Gas is the biggest national name, and as of 2025, their one-off annual boiler service typically starts from £99, with promotional prices available at certain times of year. They also offer HomeCare packages, combining boiler service and repairs, with prices starting at around £15–£20 per month for basic cover.

While the big companies are often a first thought, remember that local firms can offer more flexible, personal service without national company overheads. A smaller, trusted business will often match or beat the quality of large providers and may even be more responsive, particularly in rural areas.

Why Regular Servicing Makes Sense

It might be tempting to skip a year, especially if your boiler seems to be working fine. But investing in an annual service brings real benefits:

• Keeps your boiler running efficiently, saving you money on energy bills.
• Reduces the risk of sudden breakdowns and expensive emergency repairs.
• Upholds any manufacturer’s warranties, which usually require proof of annual servicing.
• Ensures your home remains safe, minimising the risk of dangerous leaks or carbon monoxide.

A Gas Safe registered heating engineer Spalding, for example, can give you confidence that everything is up to standard. Professional servicing is a simple step that really does offer peace of mind.

Summary

To recap, boiler servicing in the UK usually costs between £80 and £120, though specifics vary depending on your location and boiler type. British Gas charges a similar amount, but local engineers can often provide just as reliable a service (and greater flexibility). Regular servicing keeps your boiler safe and efficient, helps avoid bigger bills later on, and ensures you maintain any warranty protection.
