In the depths of winter, not only could forgetting your annual boiler service lead to days without heating, but it could also make for an expensive bill for fixing faults that you thought would be covered under warranty.
Manufacturer warranties lasting at least a few years are typically included when you buy a new boiler, and should cover the cost of repairs if yours breaks down or develops a fault, letting you rest easy for the first few years of a boiler's life.
But fail to stick closely to the warranty terms and conditions and you could find yourself unexpectedly out of pocket. Read on to discover the potential pitfalls to avoid, and how to make sure you stick to your boiler warranty's terms and conditions.
Minimise the risk of your boiler breaking by installing one from a reliable brand in the first place. Read our boiler reviews to find the best.
The specific terms and conditions you need to stick to will vary by warranty, so it's worth reading the small print carefully. But avoiding these three common mistakes will stand you in good stead, as they are common across most boiler warranties.

When installing a new boiler, you typically get a manufacturer warranty on it that covers the cost of repair for at least some boiler problems - provided you adhere to the T&Cs.
Gas boiler warranties usually last several years, with some manufacturers offering warranties that last for 10 years or more.
Oil boilers tend to have shorter warranties, and electric boilers typically offer warranties for only two or three years. This doesn't mean that they're more likely to break down in this period, but that the manufacturer won't necessarily investigate the fault after this time.
Not all warranties are created equal. If you value extra peace of mind, then the quality of the manufacturer's warranty is something you may want to consider when buying a new boiler.
Our Best Buy boiler brands offer warranties ranging from five to twelve years. They cover the costs of both parts and labour for any repairs covered by their warranties.
When looking at boiler warranties it is worth checking the following:
If your boiler warranty has expired, read our guide on boiler repair costs to make sure you are not being charges over the odds to fix common faults.
In a recent Which? survey of boiler owners, four in 10 told us that they don't get their boiler serviced annually. We suspect this is often an unintentional oversight amidst the volume of life admin, but regardless of the reason, if you don't get your boiler serviced each year it could mean you're invalidating any warranty you have.
Regardless of whether your boiler is still under warranty, it's a good idea to get it serviced annually to minimise the risk of it conking out and identify unavoidable faults early. Prevention is always better (and usually cheaper) than cure, and nobody wants to be without heat or hot water for even a day or two in winter.
A one-off boiler service costs £86 on average, according to a June 2021 survey of 153 Which? Trusted Trader heating engineers. while if your boiler develops a (potentially avoidable) fault you can expect to pay nearly £200 for parts and labour.

Remembering to get your boiler serviced can be a pain but a new app from Benchmark (available on iOS and Android) can make staying on top of boiler servicing that bit easier.
If your boiler has been recently installed, and the installer created a Digital Benchmark record (they should have told you if they did so), downloading the digital Benchmark app acts as a digital record of your boiler's installation and servicing history.
It also sends push notifications to alert you when it's time to get your boiler serviced, making it easier to keep up with regular servicing and ensuring you keep your boiler warranty valid.
