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!

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!

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.

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!

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.

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.

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.

New Combi boiler and controls.

Our old combi boiler was installed by Gregor some twenty or so years ago, and also serviced by their engineers every year, who were always very proficient, tidy, knowledgeable, and helpful. So when it came to a new replacement combi boiler we looked no further, as we have always had excellent service in the past at a fair price. Our new combi boiler and controls were fitted by Mark, who arrived on time as arranged and was fantastic. He explained the procedures and invited any questions or problems we may have had before starting. He covered all the work arrears with dust sheets before proceeding. The whole job was professionally completed by the end of the day and left perfectly clean and tidy. Mark is a true professional who clearly enjoys and takes pride in his work, which when dealing with gas appliances is exactly what you need, he is a credit to his profession and Gregor. Excellent job completed on time and at the agreed price.

Fantastic Service

Sat chatting with my elderly father, I realised I could hear movement behind the fitted gas fire, and soon understood a bird must have fallen down the chimney and become stuck. Worried for the bird and knowing how upsetting this would be for my father (aged 97), I needed help. I tried a number of people but no one was able to assist until I called Gregor Heating. The call line operator was brilliant, taking all the details, finding if there was any help available and calling me back within ten minutes. An engineer called Phil and his assistant were willing to come out asap and help. Phil and his apprentice were brilliant. Reassuring, mindful of time for my father, they turned up and set to work straight away. It was not straight forward but they just kept on, eventually getting the fire out and saving a bewildered magpie! Throughout they made sure the room was protected and then cleaned up brilliantly at the end, reassuring me of the service on the fire so that it was not only fitted back but fully serviced and safe. I can't praise this team enough for fast help, excellent service and a very professional service. Excellent.

Wanted to praise all the team at Gregor Heating for looking after our and our tenants' boilers. Putting our tenants on the Heatplan cover was the best move we've done to put our minds at rest about boiler safety. I picked up a problem of a non working boiler yesterday and by 3 pm today Michelle and Jamal had very efficiently and professionally sorted the issue. And best of all I was called to tell me all was now well. Thanks Gregor.

From the decision being made that we needed a new boiler the team supported unwell. The assessment and quote was helpful, informed and professional. The installation was as described. It was done efficiently and professionally to an extremely high standard. There were no surprises. All of the team who we met or communicated with were polite, friendly and professional. The cost was sensible and clearly broken down. I would fully recommend this team.

Our oil boiler stopped working leaving us without heating or hot water with a cold spell on the way which was extremely worrying. The whole team at Gregor were incredibly efficient and we had our boiler working again extremely quickly including ordering the spare parts required for what is a very old oil boiler. I can't recommend their service enough. The team were all very friendly to deal with and knowledgeable in their work. They were on time and kept me informed of arrival times. We have subsequently had our boiler serviced with Gregor too and received the same excellent service. Thank you to the team and it was such a relief to have the boiler back up and running again so quickly.

Just had an annual service of my boiler and my sons boiler this morning.

Very nice man even took his shoes off when he came in, a great representative for the company.

We had a back boiler which we wanted to be replaced urgently. During the quotation survey Chris Cox talked us through the various options, taking into account what would work best for our house. His information was very helpful for us to understand what our options were and the works included removing the back boiler, installing a gas combi boiler, and replacing all the pipework and radiators. He also recommended a smart thermostat and I'm very grateful he did because I find myself enjoying it immensely now that I'm using it daily. Amazingly, he managed to book us in for the following week and the entire job was completed in 3 days, for which we are extremely grateful. The installers Mark and his colleagues were super friendly, professional and took great care whilst working in our home. Given the major job they had to do, I'm very impressed with how tidy they left everything.

We met three key people from Gregor Heating and Renewables. They were all extremely efficient, knowledgeable and highly capable - and they were really good at their trade. The surveyor who oversaw the installation, the planner who worked out the detailed specs and applied for all the paperwork, building regulations and government grant, and the engineer who fitted it all in our home. Everyone was really friendly too and went to great lengths to explain how we control our new heating system. Gregor installed a Daikin air source heat pump, a new high pressure tank and new radiators and pipes throughout the house. We are delighted with their work and very happy with the end product.

Thoroughly unsatisfactory
We have a new build house on an estate where Gregor Heating has been the main plumbing and heating contractor. We have had a number of snagging issues and have experienced ongoing prevarication from Gregor's tradespeople attending to address the problems. The worst is a washbasin problem for which we have had four visits to our house without a satisfactory resolution, and even following the complaints procedure has so far failed to resolve it. The manager from the estate development company supports us and agrees the problem requires fixing - perhaps the fifth attempt may bring and end to this sorry saga. It is not an isolated incident as a previous engineer attended when we reported a problem with stiff shower valves. He informed us that the problem was insufficiently serious to meet the manufacturers' threshold for a complaint. So we went direct to the manufacturers with support from the estate development company. The manufacturers' engineer came out quickly and replaced two faulty valves without question.
