Heat Pump and Solar PV

Excellent service from start to finish. The team on site showed great care and expertise in their work. I was happy with the quote received, and additional extra little bits of work undertaken during the job were completed as part of the original price. The work took 2 weeks as forecast. As with all extensive building work, there was the usual upheaval, but we felt they were as respectful as they could be whilst having a job to do that, in its nature, was noisy and messy. Would be happy to recommend to anyone looking for a heat pump and/or solar PV.

The company that sold me my heat pump in 2015 went into administration and I have had repeated problems in getting it serviced regularly and reliably. Thank goodness I have now come across Gregor Heating and Plumbing. Their engineer was in today – polite, competent and informative. The work was carried out with a minimum of fuss and place left clean. I also got some useful advice. Thanks also to Which Trusted Trader, who pointed me to this company in the first place.

This new boiler installation was preceded by a visit by an engineer to assess the underlying problem we had, incase a replacement wasn’t required and to thoroughly survey the requirements for the proposed work - down to the requirement for additional flue support brackets. The installation itself happened without any concerns. The engineer arrived well on time and ensured everything was working. The work was done tidily and waste was left neatly and collected by a specialist contractor just 2 days later.

Great firm

We have had an annual boiler service from Gregor for many years, usually in the latter part of the year. This time our unfortunate boiler servicing engineer called in sick and the appointment was rescheduled. It was in my diary for 9.30 am but unfortunately I had not realised that the service would be either between 8.30 am and 1.00 pm. I telephoned the main office who apologised for the misunderstanding and then later rang to say he would be much delayed owing to some difficulties. I had to leave to go to the dentist but my husband was at home when the engineer arrived - much earlier than by then expected - did the job, loved the boiler, said it was in very good condition, nice and simple rather than the more modern complicated boilers and all is well. Good firm, nice helpful engineers, helpful telephone staff.

Fantastic company to deal with very transparent had quite a few quotes and this was the only company that bothered to come around and price the job once I accepted they had their site electrician to come round and look at any potential problems changed the specifications slightly and then once paid the deposit All went very straightforward and smoothly would highly recommend this company real pleasure to deal with and also very professional. I know the owner Steve Gregor from years ago been in the construction industry myself so well done Steve all your staff are a real asset to you.

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.
