How long does a boiler last?

Not only should a good boiler heat your home efficiently, but it should also do so for a long period. If you've recently purchased a new boiler, you won't have to worry about finding a replacement for several years. In this blog, we go through how long a boiler lasts and what you can do to increase its life expectancy. 

How long does a boiler last?

The average lifespan of a contemporary boiler is between 10 and 15 years. However, if your current one is nearing the end of its useful life, it may be time to start considering getting it replaced. 

Modern and newer boilers are significantly more efficient than older boilers, especially those that have been installed more than 10 years ago. These boilers were created during a time when technology and environmental concerns were vastly different. A lot of changes in 10 years and so do the design and components of boilers, so if your boiler is between 10 - 15 years old, it is worth starting planning for a new one.

How do I increase the life expectancy of my boiler?

Here are a few things you can do to increase the life expectancy of your boiler...

Get it serviced

Having your boiler serviced by a professional at least once a year is generally a great way to ensure there are no issues with your boiler. Also, m Many manufacturers may void your boiler's warranty if you do not have it serviced annually.  Many manufacturers may void your boiler's warranty if you do not have it serviced annually.  

A yearly boiler service will help extend the life of your boiler in addition to renewing the warranty. It involves hiring a Gas Safe registered engineer to come out and inspect your boiler. A boiler service also helps identify any minor problems before they become costly and can assist in keeping your boiler in good working order.


Over time, sludge and debris can accumulate in the pipes of your central heating system, causing harm to your boiler, especially if you have an older boiler.  This can then lead to clogs and corrosion, resulting in frequent boiler breakdowns. Simply put, sludge buildup can significantly shorten the life of your boiler.  

 To prevent this, you should hire a Gas Safe registered engineer to carry out a powerflush service. This involves using a chemical that is pushed through the central heating system using very high pressure, allowing your boiler to last as long as possible. 

Fix any repairs quickly 

You should monitor your heating system for any changes or unexpected noises so that they may be addressed swiftly. If you have a suspicion that something isn't right, don't ignore it or put it off any longer than necessary. If left to worsen over time, even minor issues might result in significant repair expenses.

Don't overwork your boiler

Raising the water pressure too high might cause your boiler to wear down, and the more you use it, the lower its life span becomes. Make sure your boiler is the right size for your home and of great quality to be able to supply hot water and heating for many years.
