How much does a boiler service cost?

Monday, 15 September 2025

As the summer days ebb away and the kids return to school with memories of suncream and ice lollies fading as quickly as the temperature, thoughts turn towards the colder months of autumn and winter. Boilers that have been sparingly used during the summer will be called into action once again, and the best way to ensure it's in the best shape for the colder climes ahead is to book in a boiler service.

Regular boiler servicing doesn't only help prevent boiler failure when you need it most, but engineers should make sure it's working at its most efficient, keeping heating bills lower and lengthening the life of your boiler. But the big question is... how much will a boiler service set you back? And is it worth the investment? Read on to find out.

What does a boiler service involve?

Once you've found a qualified heating engineer for the job, you'll need to arrange a date and time for them to turn up to your property and perform the service. It goes without saying, you'll need to be present to let the engineer into your home. A service typically takes around an hour, though it can take longer depending on factors we'll discuss a little later.

The engineer will begin with a simple visual inspection of your boiler, looking for any obvious signs of leaks, corrosion, or damaged pipework. After that, the engineer will dismantle the boiler into its component parts, allowing for a more detailed inspection.

The boiler will then be cleaned and vacuumed to remove any excess soot, before running the system to monitor carbon monoxide levels, pressure, flue temperature, and efficiency. All electrical wiring and controls will be checked, before a final test confirms that the boiler is in good working order.

Should the engineer diagnose a problem that can't be mended on the day, a return visit with replacement parts may be needed.

Typical boiler service cost in North Tyneside

As with most services in the UK, the cost of a boiler service varies depending on location, but the average range is between £80 - £120, with residents in London and the South East expecting to be at the higher end of that. Here at Koziwarm, our thorough annual boiler service, performed by qualified heating engineers, costs just £84.

Factors that influence boiler servicing prices

Although most heating engineers will offer a standard price for a boiler service, this price is liable to vary depending on a number of factors. We've mentioned the geographical dynamic already above, but there are other considerations.

Alternative boilers, such as oil or biomass, are typically more expensive to service than their gas equivalent. Any work that is likely to take longer than an hour will also result in a higher cost. In this regard, the age of your boiler, when it was last serviced, and how easy it is to access will be key.

There's also the time of year to take into account. When the UK's chilly winds, punishing rains, and plummeting temperatures take hold, heating engineers are in high demand. As such, it can be cheaper - not to mention less stressful - getting your boiler service booked in off-peak months.

Is an annual boiler service worth it?

Given the website you're reading this on, you'll not be surprised to find that our answer here is a resounding YES. The price of an annual boiler service is easily dwarfed by the costs of emergency boiler repairs or replacements, the chances of which are far reduced when your boiler gets regular TLC.

Another thing to note is, if your boiler remains under warranty, it's very likely that an annual service is a condition of the agreement. Skipping a service could render your coverage invalid should your boiler breakdown.

And lastly, but most importantly, a regular service for your boiler provides peace of mind that you're protected against dangerous gas or carbon monoxide leaks.
