There are many parts of a boiler service. On arrival our engineer will check that the boiler location complies with current Gas Safety, and building regulations. These regulations can change regularly and if your boilers location doesn't comply with these regulations it will have to be moved before passing the service.
After checking the boilers compliance with safety regulations the engineer will then examine all external controls and panels connected to the boiler. Once the engineer is happy that these electrical components are working correctly they can move on to the main part of the boiler service.
