Top Quality Solar PV Service and Fitting from one of the Best.

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.

Boiler Care for tenants

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.

Have used this company for years. Very reliable. Very helpful. Back up/call out service for maintenance is very good. A local company with local employees who know their clientele and their needs very well. May not be the cheapest or the dearest but certainly very competitive and reliable. Would recommend local Bristol/Bath people consider using this local company.

Have used Gregor heating for many years, easy to book annual service and years of emergency cover. Any problem they are there for you. They have excellent knowledgeable engineers who are prompt and courteous, explaining what is required. They have several maintenance cover schemes to suit your needs at very reasonable prices. Would not want to use anyone else.

Replacement Boiler - a professional job

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.

Phil Boobier attended to fix and issue with my boiler, it was a pleasure to meet him. He was helpful and a very good communicator, he explained to me exactly what the issues were and how he would troubleshoot the issue. Having someone take the time to explain what he was doing was very refreshing, he was very good at explaining everything in lay terms. He fixed the problem very quickly.
