Our ground source heat pump had failed. Grant from Gregor heating had come out and fixed it but were still short on glycol for the system and he noted that two valves needed repairing. He returned as agreed last Saturday and fixed the outstanding issues in 45 minutes. Brilliant sservice. He was neat, tidy and courteous as usual, Well done Gregors.

The company made arrangements that fit with our schedule, the engineer was polite and got the leak fixed. Can't fault the service at all.
