Having recently moved home and not having gas central heating at our previous address we didn't know who to call to service our boiler. After checking out the Gas Safe register and finding Quadraheat Ltd. and then reading their reviews it was a 'no brainer'. They had an overall rating of 5 and we soon found out why. It was excellent service all round, from our initial phone call to job completion a couple of days later. Although the boiler service wasn't an emergency they knew our thermostat wasn't working as well so fitted us in very quickly. Sorted the thermostat and serviced the boiler early one evening. An absolutely first class company who we will continue to use for our annual boiler service and any other gas related problems.
