Our boiler power was completely off so we did an emergency call out. We were seen within the hour despite the guys having boilers effected by a water leak in the area to deal with. Friendly, efficient service and the issue was the switch had been turned off! The engineer took the time to show me what each switch and element of the boiler actually was, should this happen again. Highly recommended this for that kind of workmanship. Their service costs sound very reasonable so I will bear them in mind.
