   Dawn arrived early but didn???t knock until 8(planned time). She was very helpful explained everything and talked to us through what service plan we needed to take on now that our boiler is nine years old. She set up all the forms and submitted them to Gregor Heating so no effort from our point which was great Dawn I saw you two years ago and you were good then and carry on. You???re still good now thank you.

   0 STAR REVIEW - SHOCKING COMPANY My experience with Gregor Heating has been extremely bad. Gregor Heating was involved in a number of installations and repair works at my new-build property, many of which subsequently became the subject of repeated defects, failures, and return visits. The most serious issue concerned the heating system. They call themselves as "renewable specialists" but can't get the basics right (i.e fitting a toilet seat). The heat pump was installed by them with the flow and return pipework REVERSED, which is a fundamental installation error. They later SIGNED OFF THE SYSTEM AS COMPLAINT! Despite this, I spent months trying to obtain clear answers regarding the impact on the system and the ongoing issues that followed. The brand new heating system installed by them has been malfunctioning, not working at the time of independent inspection, randomly stopping, making a loud banging noise after each hot water cycle. The Gregor "specialists" have not been able to resolve any of these issues despite them visiting the property multiple times. Other issues produced by the Gregor's "specialists" include: - A bath cold tap that supplied hot water (!) - Loose toilet seats that required multiple visits and still repeatedly became loose afterwards (!) - Leaking internal pipework; - A leaking reducer between the incoming mains water supply and internal stopcock within the first year of occupation (!) - Leaking and loose guttering; - Ongoing heating system faults and performance concerns. - pipework that is not clipped within the walls and ceiling which resulted in the pipes knocking against plasterboards (!) - pipework not secured in the kitchen cupboards. - toilet water valves malfunctioning and making noise. What was particularly frustrating was the number of repeat visits required and the apparent inability to permanently resolve issues that should have been straightforward to diagnose and rectify (bear in mind that it is a new house and apparently new items). I was also disappointed by the attitude of some members of staff. On occasions, legitimate concerns were challenged or dismissed rather than investigated properly, which created an unnecessarily confrontational experience when I was simply trying to have defects resolved. As a shared homeowner, I would expect a contractor involved in new-build installations to demonstrate a high standard of workmanship, accountability, and professionalism. Unfortunately, based on my experience, Gregor Heating fell well short of those expectations. I cannot recommend them based on the quality of work, the number of defects encountered, the repeated repair failures, and the overall customer experience. It's has been absolutely awful and they should be reported to the trading standards.

   Had our first boiler service and was very pleased with the communication form booking to appointment day. The engineer turned up on time and was very helpful and polite. We have now signed up for Gregor???s heat plan.

   My whole experience with Gregor Heating has been excellent. Their quote was competitive and everyone I have dealt with have been really professional. We had some minor technical issues after installation but they responded very quickly and it was resolved in less than 24 hours. Would highly recommend them.
