Boiler Service Cost: What You Need to Know

If you own a boiler, you’ll hear about a "service" at least once a year. But how much should you actually pay? The price can swing a lot depending on where you live, what type of boiler you have, and who does the work. Below we break down the usual numbers, explain why they differ, and give you a few ideas to keep the bill low.

Typical Boiler Service Prices

In most parts of the UK, a standard annual service costs between £80 and £120. That’s for a basic check‑up: the technician looks at the pressure, the flame, the gas safety, and cleans the heat exchanger. If you have a modern combi boiler, the price is often at the lower end because the system is compact and simple.

Older or larger boilers – such as system boilers or oil‑fired units – can push the cost up to £150 or more. The extra charge usually covers more time on site, additional parts, and sometimes a thorough cleaning of the flue.

Some companies bundle a service with a small repair, like fixing a leaking valve. In those cases the total might be £200‑£250, but you get the repair included. Always ask what’s in the quote before you sign up.

How to Keep Costs Low

First, shop around. A quick phone call to three local firms will give you a price range and show how transparent they are. Many reputable companies post fixed service fees on their websites – that’s a good sign they won’t surprise you with hidden costs.

Second, schedule the service before the winter rush. Technicians are busiest in October and November, so a spring or early‑summer appointment often comes with a discount.

Third, do simple maintenance yourself. Bleeding radiators, checking the pressure gauge, and keeping the area around the boiler clear of dust can help the engineer finish quicker, which can lower the labour charge.

Finally, look for a service plan. Some firms offer an annual contract for £70‑£90, which includes the yearly visit and a small discount on any extra repairs. Only sign up if you’re comfortable with the provider’s reputation.

Bottom line: a typical boiler service costs around £100, but you can often shave £20‑£30 off by comparing quotes, timing the visit, and handling basic upkeep yourself. A well‑maintained boiler runs more efficiently, saves you money on heating bills, and lasts longer – so the small service fee is worth it.
