Phil from Gregor Heating worked through his breaks & past the end of the day to ensure we were left with hot water and heating in the winter for our children. Fantastic service. Couldn't recommend higher!

They adjusted their normal response time to reflect a dire emergency as I had no heating at all. They were prompt, fast, and efficient and competitively priced. The workmen were young and had already a well bounded sense of a professional approach.

After our boiler breakdown in December we were delighted with the service we got from Gregor Heating. Everyone was helpful and professional. Our engineer Mark was brilliant - a credit to the company - he was very thorough, and knowledgeable and he executed the work with the minimum of mess. Thanks to all concerned

Due to a gas leak I was without heating or hot water - not so good with my wife having just come out of hospital. Having previously used Gregor for a boiler installation contacted them to see if an engineer could call. Paul arrived within 2 hours and proceeded to identify the source of the leak and go ahead and make this good with the minimum of fuss and disruption. At all times he informed me of what he was doing and why and patiently answered all my questions. Heating and water restored, leak repaired, wife happy. Excellent service and will not hesitate to use again or recommend to others.

We had a few companies quote before Gregor but their sales guy/customer service and helpful staff as well as price were head and shoulders above the rest. No mess, no disruption, lovely guy and everything that was needed after install was done promptly and as promised. Would highly recommend! Thank you.

My wife and I are both in our mid eighties, and in December my wife was taken into hospital. On the 13th Dec, my old Ideal boiler gasped it's last and I was told a new boiler was needed. A relative told me about Gregor Heating. I rang the company the next morning, explaining my predicament. By 2pm the sales manager came to see me and within a half an hour the quotation was composted, printed, and in my hand. The quotation was accepted and installation was arranged for 19th Dec. The installers arrived just before 8am and was completed by mid afternoon. I cannot thank everyone enough at Gregor for their commitment. Finally, the work was completed before my wife returned from hospital.

Having struggled to find good service from a number of 'professional' contractors, we decided to go to a recognised firm and definitely were not disappointed with Gregor, they were excellent. The two chaps that came over, Craige and Jordan, were excellent and were great representatives for the company - polite, knowledgeable, hard working and more than happy to help. We would use the company again because of them. It was good to see that Jordan was an apprentice and was given time and support by Craige as well as having a training day. Was good to see the commitment of the company and the more experienced staff. There were problems around the invoices but the staff in the office sorted it quickly and efficiently. I would definitely recommend using Gregor.

No instructions given. Boiler stopped working, but it was my fault. I bled the radiator, pressure dropped. When rang for assistance, no one called me back. Had to ring next day. Only by chance when engineer was due, looked out and he had been sent to wrong address.

Having no heating or hot water for over 2 months was pretty hard going, Gregor couldn't come out to install as quickly as we'd have liked, but they came very quickly to do the initial quote. Once the plumber arrived, he made the disruption of having the boiler replaced super easy (almost pleasurable!) and Mark specifically was a delight to have in the house. I wasn't here when Mark left so I was unsure about how the job would be finished off, however when I spoke to Sarah in the office this afternoon she very quickly sorted exactly what was happening and called me back to reassure me that all would be finished. The delay is a little bit of a pain - I need to dust after the ceiling was pulled down but can't until the new ceiling is installed - but I'm just happy we have heat and water again! So far we have had nothing but good experiences with Gregor, and we would absolutely recommend them to others. I'll update as the services they provide carries on.
