Is a Boiler Service Necessary?

Is a Boiler Service Necessary?

The short answer to that question is ‘yes’. Boiler services are much like visiting the dentist; not very glamorous and it feels unnecessary to spend money on something that won’t be noticed or isn’t an emergency. However, to enable your boiler to work efficiently and stay within its standard warranty, a regular boiler service is very necessary.


 If you think about it, it’s like checking the oil, water and tyres on your car before driving your family across the channel to the Dordogne. Can you imagine not giving the car the once over before leaving? Even if you think there is nothing wrong with your boiler, the complications that can occur are not always visible to the untrained eye.

Broken boilers are not fun, and it’s always sods law that the boiler packs up when you have a house full of guests in middle of a cold snap. If your boiler is serviced regularly then your dedicated engineer will have notes on your boiler and the state that it is in, so the fix can be quicker and simpler (in theory). This will keep things ticking on throughout the long winter months when the boiler is on for longer and having to work that much harder.
