New heating system
Customer Service
On moving house I had problems with the existing boiler and system (it was very old). Gregor helped keep the existing system going whilst I waited for a new system to be fitted. They were very flexible in fitting the new system by completing some pipework early so we could finish fitting our kitchen and then on full install working with the plumber fitting our new bathroom. Chris, Mark and Phil delivered a great service. This is a great business and you feel confident that the new system is professionally fitted and if there are any problems they will be sorted quickly.

Solar installation
Customer Service
Gregor installed solar panels on the roof of our house together with a battery, car charging point and all the necessary electrical equipment in between. We invited three companies to provide prices. The three quotes were similar but specified very different equipment. Gregor stood out from the other two by their professionalism, giving sound advice on, and a choice of suitable equipment for our situation. They were also the only company to advise on and come up with a solution to issues with roof loadings. The works were undertaken on time and to the agreed budget and whilst working in the house Gregor’s technical team of installers were helpful, provided good communication and were very respectful of our property. There was one hitch along the way, but that was rectified without question and very speedily.

Simply the best!
Customer Service
From start to finish Gregor Heating are a delight and pleasure to deal with. They are great value for money, the crews that come and do the actual installations are simply brilliant. You would not wish for a better experience. The boiler is exactly what we wanted, they were clean, tidy and as quiet as they could be (working office installation). On time every day and great fun to have around. I have had them install my boiler at home as well and will always go back to them in future and recommend them to everyone.

Installation of a replacement gas boiler
Customer Service
Gregor Heating were referred to us by a previous energy company in October 2023 who could not guarantee that they could replace a defunct gas boiler before Christmas 2023. Gregor quickly sent out Chris, their Sales Manager, who made a detailed inspection and, during his initial visit, gave us a design and price for a new installation. We accepted and their gas engineer, Mark installed a replacement boiler for us during the week 06.11.23 and 10.11.23. At all times he was on time, polite, friendly and worked hard. All went well and Mark explained what he was doing and why, giving us various options as he went. We had full confidence in him, and with his electrician colleagues, especially Martin, who was very helpful in explaining what he was doing and why. He also gave us valuable advice on our solar panel installation. In summary, we were delighted with our service from Gregor Heating.

Servicing heat pump
Customer Service
Two professional gents worked quickly and tidily to clean out the heat pump then came indoors to test levels of antifreeze and advise me on the safest temperature to use in my hot water tank. They were pleasant and polite. I can recommend Gregor Heating .

They did an amazing job. Craig was very professional and efficient, the house was left in a great condition. I was amazed on how well the job was done for replacing a back boiler with a new one. Chris was also very good when he did the survey, everything was clear. I would definitely recommend Gregor!

Customer Service
Had John Dillon come round and sort out a leak around the bath. He was polite, professional and offered a great solution. Spent about 4 hours sorting things out and left me with instructions on what to do for the next step. We also had a nice chat about steak, which is unrelated but I got some good butcher's recommendations!

Great work!
Customer Service
The engineer Phil Boobier, turned up on time and was very helpful and friendly, and he explained everything clearly, there was a defect part which could have been potentially dangerous and after showing me why he promptly replaced it, the whole experience was great from the beginning, the pleasant manner of the office personnel when I made the appointment and as a result I have signed up for a service plan with them which is very reasonably priced. I thoroughly recommend this company.

Toilet replacement and correction of vanity unit drawers
Customer Service
John Dillon from Gregor came to replace a faulty toilet today. He has done a great job and was clean and tidy with his work. He also sorted out the double vanity unit Duravit drawers. They had not been installed properly and were leaning forward meaning that the top drawer did not always shut. John has sorted this out and we are very pleased with the adjustment. Thanks a lot John!
