Why Have A Boiler Service?


All Boiler manufacturers recommend that their Boiler’s are serviced annually by a Gas Safe Registered Engineer, in fact neglecting servicing invalidates manufacturers warranties. Also, many home emergency service cover policies require annual Boiler servicing for validation (for boiler breakdown)


Boilers are fuel-burning appliances that are used daily so vital internal parts get dirty, so need cleaning. Boilers also deal with water which is corrosive by nature. Boilers (especially older ones) are prone to springing leaks.

During the service, we’ll check for leaks, around the casing and the inside pipework. All seals are checked for tightness and adjusted as necessary. If seals are corroded and leaking, they are replaced. Faulty valves can also leak usually caused by incorrect pressure in the system, all valves are checked for leaks and to ensure that function correctly.

Consistent running

Waterflow is checked, incorrect flow usually caused by limescale or debris in the system can cause constant switching off of the Boiler, annoying and inconvenient.


For efficient running Boilers need to burn gas at the proper rate. The gas burn rate is checked and adjusted until it’s burning at the correct rate. This ensures waste fuel is minimised and your Boiler will run at maximal efficiency.


For Boilers to run safely, the flue and ventilation must be in order to expel all noxious gasses that can lead to carbon monoxide poisoning. By testing the flue and ventilation, we ensure that carbon monoxide isn’t a risk. Please ensure you have a working Carbon Monoxide alarm near your Boiler. While servicing dramatically reduces the risk of carbon monoxide poisoning, you want to be as safe as possible.

The Boilers also checked for leaking gas which can be fatal.

All safety devices (which prevent damage in case the Boiler ever suddenly stops) are checked to ensure they’re working correctly.

System Check

After the service, we’ll switch your Boiler and make sure it’s running correctly. We can check that radiators are warming up and bleed as necessary.


Boiler servicing uncovers issues which we can make recommendations that you can plan for at a future date.
