Why is it important to have an annual boiler service?

You may be wondering, why do I need to service my boiler annually? We’re your heating specialists in South London and can reassure you that a boiler service will benefit your boiler and, by extension, your home’s hot water, heating, and energy bills. Let’s find out more:


Regularly servicing your gas boiler can ensure that it maintains its efficiency. With modern boilers performing with over a 95% efficiency rate, just a slight reduction of this rate can have a massive impact on your gas bills.


Servicing your boiler annually means that problems are spotted earlier, and any parts that are not working as they should can be replaced before greater damage is done. This saves you money in the long run and ensures that your home stays warmer for longer.


During your annual boiler service, a full safety inspection is also performed. It looks for damage or failing parts; for example, the integrity of the flue which takes the gas out of your home. It is vital for the safety of your family and your home.


If you have had a new boiler installed in your home in the last few years, the chances are that you received a manufacturer guarantee or warranty. All manufacturers require boilers to be serviced annually for the guarantee or warranty of the boiler to remain valid.
