Have used Gregor Heating for a few years now; very happy with the service. Jamie, my engineer this morning, rang before arriving, and arrived on time. Jamie was the engineer that attended last year; he is friendly, engaging, and very knowledgeable. He got on with the job, worked diligently and quickly. He was polite when asking for access, and explained the process and results in detail. We had a conversation about the likely life of my boiler and replacement options (it's getting on a bit) and he was very helpful with his suggestions and recommendations. He clearly know his business but was honest about his knowledge when it comes to new tech he has not worked on directly. I'd certainly trust his opinions. Booking appointments, changing them, and dealing with payments has also been easy and hassle free. I have had really good experiences with Gregor Heating and have no hesitation in recommending them.

Just had an annual service of my 5-year-old Worcester Bosch boiler which was installed by Gregor Heating and serviced every year by Gregor Heating. The Engineer Phil Boobier arrived on time and was extremely pleasant, very professional and a good communicator. He described everything he did as he was doing it and then explained all the test results so I was left confident that the boiler was operating safely and efficiently after Phil had completed the annual service. Phil did not make any mess and left everything clean and tidy. Phil is an excellent ambassador for Gregor Heating and I will ask for Phil to service my boiler again next year.

Gregor Heating are clearly at the forefront of installation of renewable and smart technology. I was able to have sensible discussions about system design and the installation was professionally done. It was 5 months between quote acceptance and completion of the job. Supply issues outside of Gregor's control was a significant part of this but their busyness did also contribute to the delays.

Mark arrived promptly at 07:30 to fit our new gas boiler, he was neat, tidy and efficient, he was also very friendly and made sure from the start that he covered our carpets and kept our house clean and left it as he found it. The old boiler and rubbish was collected during the morning by Mark's colleagues and the electrician arrived to do his bits. When he had finished the installation Mark explained what he had done. I have great pleasure in recommending Gregor Heating and all their staff that we had contact with, especially Mark the engineer, I was very impressed with his work ethic and professional standard of work, a genuine ambassador for Gregor Heating.

Air source heat pump service: My initial phone call was dealt with in a friendly and very efficient manner, and a date was set for the work, together with costing. The engineer arrived on time, came across as knowledgeable, and again, had a friendly manner which instilled confidence. When the service was completed, he explained what he had done, and completed the service record. The invoice was sent the following day, and payment over the phone was processed quickly; the person dealing with me was very helpful. A very satisfactory experience from beginning to end.

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.

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.

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.

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.

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.

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

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.

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.

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.
