A relatively expensive installation, but efficiently and courteously handled.

I had my boiler installed by Gregor Heating and I was really impressed. They did a brilliant job, very professional from start to finish really looking after me. I didn't realise my old boiler was so inefficient! I would highly recommend this company and would definitely use them again.

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.

From the moment we picked up the phone to arrange a quote, the service we received was prompt and professional. The guy who carried out the work was friendly, knowledgeable and very good at tidying before he left, which was helpful with a small baby.

I would just like to say that the guys at Gregor Heating are wonderful! I had a heat pump fitted last week and my goodness the difference in the heating is just phenomenal! A big shout out to all the guys who fitted the system and especially to Ashton who was the most polite, helpful and OCD clean freak heating engineer going but all the guys were fantastic. I also have to say the customer service guys and gals on the phone have been just as awesome! I recommend Gregor heating to everyone as the whole service that they give is totally above and beyond so thank you! ⭐️️⭐️️⭐️️⭐️️⭐️️⭐️️⭐️️⭐️️⭐️️⭐️️⭐️️⭐️️⭐️️⭐️️⭐️️⭐️️

We were disappointed that your fitters arrived late. I had to contact your office twice. There was no phone call or explanation or apology. we were waiting for an hour and half wondering where on earth they had gotten to.
