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 .

Fast, effective, top quality!
Customer Service
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!

high standard of work
Customer Service
Gregor put a new boiler in for me. I chose them because I got solid advice from them on my initial enquiry. They mentioned aspects regarding gas regulations that another company just didn't mention (because it complicated things). I wanted someone to do the job right so chose Gregor. Communication was good. I'm not a plumber but they seemed to do a tidy, professional job and I'm happy with it. There were a couple of problems encountered during the install, but they resolved them quickly and without fuss. I would certainly recommend them.

Solar PV and Battery Installation
Customer Service
We are very pleased with the solar pv and battery system installation undertaken by Gregor Heating. The whole team from first contact with sales, to the survey and installation team were all very professional, polite, tidy and friendly. When there was an issue with the first battery that was delivered being faulty this was all handled by Gregor with only impact to us being a slight delay in the completion of the install. I would have no hesitation in recommending them to anyone considering similar work.

Top Quality Solar PV Service and Fitting from one of the Best.
Customer Service
I wanted to ensure I got my Solar PV system from a top-quality and reputable company and couldn't have made a better choice than Gregor. Highly knowledgeable and professional service catering to my exacting requirements, and ensuring I got value for money. Delivered a Solar Edge system that future-proofed me for later enhancements that will enable me to go off-grid during a power cut. Excellent service and highly recommended.
