Professional service from quote to completion. Only criticism was re: communication - They originally told us boiler would be fitted day 2 but in fact all work was day 1. Also there was follow up work to roof which had to ring to chase.

The heating was put in my mother's house. She was very pleased with the job. The person that put her heating in was very helpful to her and always cleaned up after himself each day. More than happy to recommend Gregor.
