How long do boilers last

How Long Do Boilers Last?

In our experience, boilers are most commonly replaced when they reach between 10 and 15 years old**. Here are several factors which could influence the lifespan of your boiler:

1. Boilers may become less efficient over time, we usually recommend that you start considering a new boiler when your current system is approaching 10 years old. An old and inefficient boiler may have to work harder to heat your home; whereas a new efficient boiler could potentially save you up to £210 each year in energy bills*.

2. Having an annual service on your boiler could help your boiler keep ticking over as it should be. A service includes various tests on efficiency and performance, and also checks for any leaks or faults in your system. Regular servicing can be a good way to nip any faults in the bud early and may be one of the requirements to keep your manufacturer warranty valid.


3. Although some boilers may far out live a typical life expectancy, parts and spares may become unobtainable for older boiler models which may lead to a bigger problem if a repair is needed.


4. Technology in the boiler industry is constantly developing, so a new boiler could not only be more energy efficient but could also incorporate any array of new features, and could potentially become easier to use and could look more aesthetically pleasing in your home.


5. If the conditions of your home change significantly since your boiler was installed, the boiler may no longer be suitable to perform efficiently to supply the amount of heat and hot water that you require. For example, if you have had added more bathrooms or rooms through a house extension or loft conversion, then your boiler may require more power to operate to your new demands. Overworking a small boiler which was not designed to cope with these new high demands, may cause the boiler to degrade more rapidly than usual. If you have had or are considering additional bathrooms, rooms or radiators in your home, it is best to keep in mind the impact this could have on your boiler and central heating system.

Some signs that your boiler could be coming to the end of its life may include (but are not limited to):

• Persistent breakdowns

• A high-cost repair is needed

• Flue problems

• Fuel efficiency and environmental pollution

• Boiler noise
