Battery and Smart Control installation
Customer Service
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.

Great work fitting our new gas boiler
Customer Service
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.

Excellent service
Customer Service
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.

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.
