Excellent
This was my first experience of using Gregors for servicing the boilers in my home and two of the other buildings I have responsibility for. The engineer was Darren, who deserves a full 5 stars three times over. He carried out a very thorough inspection and service in a very professional and friendly way. Based on my experience with Darren, I will have no hesitation in staying with Gregors for the foreseeable future.
