How long does a boiler last?

Boilers are an important part of your home life, there to provide you with heating and hot water whenever you need it. However, over time they do begin to show signs of ageing and will need to be replaced.

When should I start looking to buy a new boiler?

Boilers tend to last around 10 to 15 years, but this is dependent on your boiler model, how you use it and how well it has been serviced. A poorly maintained boiler may need to be replaced sooner than 10 years, which is why, as well as ensuring your boiler is working efficiently and safely, having an annual service to keep your boiler safe and healthy is cost-effective in the long run.

Helping your boiler's lifespan

Servicing your boiler - how it'll help with your boilers lifecyle

You use your boiler daily, so having it serviced can help reduce the impact of wear and tear throughout its lifespan. If your boiler isn’t working at its best, it could make your monthly utility bills go up. Your annual service makes sure there are no performance issues. Not only that, your engineer will look for any potential dangers, such as carbon monoxide leaks. Monitoring its performance and fixing any issues early, helps you get the maximum life out of your boiler. 

The best way to do this is by having your boiler serviced regularly either through a service plan or taking out boiler insurance to protect you.

How often should a boiler be serviced?

We recommend that you have your boiler serviced at least once every 12 months.

 If you live in rented accommodation, your landlord is legally obliged to have your boiler (and all other gas appliances you use in your home) serviced once a year, with a gas safety certificate being issued at the end of the inspection. 

For homeowners, an annual service may be necessary to avoid voiding your boiler’s guarantee. If your boiler breaks down and you haven’t had an official inspection within the past 12 months, you’re unlikely to be covered under the manufacturer’s warranty.

What if something goes wrong and I’m not due a service?

If you are noticing issues with your boiler, such as low pressure, signs of overheating or a leak, arrange an engineer to take a look as soon as possible - don’t wait for your annual inspection. The possibility of gas leaks and carbon monoxide means that faulty boilers are a health risk, so it’s better to pick up an issue early and fix it quickly than for it to get worse and become a potentially dangerous and costly problem.

If possible, try to arrange your boiler service during quieter periods of the year. In colder, winter months, where demand is higher, it may be harder to arrange an inspection date. It’s also better to fix any issues during summer months when you require less heating for your home.

What's included in the boiler service?

The engineer will run safety checks to ensure that it’s operating properly and raise any potential performance issues. They’ll look for any visual signs of damage, check for correct pressure and flow and also give the inside of your boiler a good clean. If a small issue is discovered, your engineer can usually fix it straight away. If the problem is slightly more complex, they may arrange another date to fix the issue. After the inspection, you‘ll get a post-service report which you need to keep for any warranty purposes.  If you want to have annual services, it's worth considering taking out boiler cover.

How long does a boiler service take?

Overall, a boiler service takes less than an hour of your day but helps to ensure your boiler is working properly, keeping your bills as low as possible and gives you the chance to catch small issues early, rather than dealing with costly fixes later on.
