Understanding Boiler Servicing & Repairs
Recognising when you require a boiler service versus a heating repair is vital. Boiler servicing, akin to a car’s MOT, is an annual check-up for safety, efficiency, and performance, including replacing specified parts as instructed by the manufacturer. Mainly, a boiler service is preventive, catching issues before a complete failure, the annual MOT for your boiler!
Boiler repairs, however, are required when a breakdown occurs and your boiler stops producing heating or hot water. Our standard boiler servicing and “Cosy Plan” service plan does not cover repairs or faulty boilers, focusing instead on preventive maintenance.
