Installation of new boiler
Customer Service
The engineer arrived promptly and installed the boiler very efficiently. The old boiler and waste was collected that morning. The electrician arrived later that day and the whole system went like clockwork. Additional work was found to be needed on an old rusty leaking radiator. This was inspected immediately, a quote given and the work expedited. All the staff were helpful. I am very pleased with the work done and would recommend this company.

Informative and friendly service
Customer Service
Booked our yearly boiler/gas fire service through Gregor’s heat plan cover. Welcoming and supportive office staff scheduled the visit. A new engineer, Darren P, arrived promptly and conducted the inspection and service. Both friendly and professional he explained what he was doing and as he went along. He also ensured that I was happy with how the boiler was performing and understood the controls to make sure we got the best performance. He was tidy as he worked and ensured he completed the paperwork -and sent an email of all the details before he left. Another great experience from Gregor Heating.

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.

Good product fitted, good engineer installed it, lacking communication throughout
Customer Service
Mixed feelings of Gregor Heating. Being a local company that is respected in renewables, i chose to use them to replace an existing Solar Diverter. Initial discussion with an engineer via phone, he suggested a product + I was interested in batteries too. I received a quote for both products. I decided to go with Solar Diverter only at this stage - their finance system couldn't cope with this, and all the way through and even to final payment, the invoice quoted 'battery+inverter' and not 'solar diverter' (even though price was correct for diverter). A request for 50% deposit arrived, stating "We hope you are pleased with the works you have had carried out. " and requesting a review. I hadn't had any work done at this stage, nor agreed a date for the work to be done! Eventually someone called me to book the installation for 2 months time (my request for this time). From then until electrician turned up 9.30am on the day, I wasn't sure whether they would attend i.e. no communication to follow up and check all was good for this day. Electrician was great, installed in good time and explained the product and how to use / monitor it. Product also is good and works well. So - great installation service and product, but invoice system & communication with me could have been much better, something which I'd hope would be better for a local company.

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.
