The Gregor team, Craig (plumber/gas engineer) Lee (electrician) and the builder were great. They were punctual, polite, friendly, hardworking, and answered all of the many questions I had. They were very professional and their work is of a very high standard. At the end of each day they made sure my property was left clean, tidy and ready for our use. They instructed me as to the use of the boiler and thermostats as necessary and left all the necessary paperwork/manuals and instructions. I recommend them.

We had a new boiler fitted to replace our ancient one. Adam initially explained all of the options really well to us and was really responsive whenever we had any questions. Mark who installed the boiler for us was really professional and courteous. Everything was always left tidy and he explained the process to me clearly. All looks great, was finished on time and is working well. The electrician and builder were also really friendly and professional. Overall a really great service.

My family and I are extremely pleased with the recent boiler install by Gregor Heating. The whole process from site inspection to quotation to installation went without a hitch. All questions answered and no problem insurmountable. Connor, the engineer, was a pleasure to have in our home; friendly, courteous, knowledgable and professional. He arrived when he said he would and finished early! I am delighted to say that the water is now piping hot and I am very happy! I would have no hesitation in recommending this company.

From the competitive quote by Adam to the completion of the job within the estimated time. The installation was carried out to a very high standard. Conor arrived on time and covered all carpets and proceeded to discuss the procedure in a courteous and efficient manner. He overcame problems caused by our 40 year old system and obviously took great pride in his job. He kept the disturbance down to a minimum showing great care .John the builder made good the changes to the kitchen and the electrician was very efficient and patiently explained the room thermostat .On completion the . house was vacuumed and all waste removed within hours .We would not hesitate to recommend Gregor Heating to to anyone. Thank you to all the team.

Quote was given on day Adam called to do survey. Although not the cheapest quote we received we liked the service and attitude of Adam so agreed to work being carried out by Gregor. An administration error on the date of work commencing meant Craig arrived a day earlier than we expected. This was all sorted and from then on we had absolutely no problems or cause for complaint. Craige arrived with John and in no time at all old tanks were removed repair work carried out and rubbish removed from our property. Craige was very polite and a good clean worker. He worked very hard and explained everything very well. Several engineers arrived to help Craige so the job was sorted and finished on time. Even had my stairs vacuumed. An electrician arrived to fit the Hive, he explained how it works so all good. ( I’ve yet to try it!). All paperwork arrived and we were very happy to settle our account knowing our first service is included. We later had a problem with a leak on the hot water pipe leading to our shower. We realised this was not a problem with boiler installation but on contacting Adam desperate for advice he arranged for Conner one of their engineers to call. He found the problem and he was able to stop the leak. So many thanks this service was over and above. We can highly recommend Gregor Heating from start to finish we are very happy with every aspect of our experience.

Had a new combi boiler installed to replace my 30 year old one. Initial survey and guidance excellent. Price and terms competitive. Engineer turned up on time and from the start was highly knowledgeable and skilled. Very tidy and considerate and the few small issues he came across he consulted with me as to my options to overcome them. Done within the timescale promised and was very happy to answer all my questions regarding what was going on. Old boiler, tanks etc removed and sent to recycling. After care includes free service and plan for a year. Would very highly recommend them.

Excellent service from first visit to final clear up. Craige was first class, very polite helpful and professional. The coordination of staff, equipment delivery and scrap removal was well planned. Work was carried out to time with slight changes to the plan that made the installation plan more suited to the layout of the property. Would recommend Gregor to all.

Great experience with Gregor heating. Installer (Craig) arrived on time. Friendly, helpful and arrived with electric heaters to see me through the one night without heat. He worked an extremely long day, got everything done promptly and I arrived back from work on day 2 to warm house, everything set up and the house cleaned/hoovered with the only evidence he had been there a brand new boiler. Cannot praise highly enough.

Really good, from quote to finish. Very informative initial appraisal and quote. All the team were very courteous. Craig M the main installer deserves special credit. He persevered to find a solution to an awkward pre-existing pipe arrangement. We’d resigned ourselves to losing bathroom tiles at a minimum. However, Craig found a clever way around this. Also when a minor communication problem (wrong tel number on record) transpired after he’d finished he went out of his way to sort it out. Lee and John were timely and friendly too. Quote was a bit higher than others but the assured quality made it worth it.

Following an old boiler breaking down and having no hot-water or heating, wanted a good reliable installer to provide and fit a new boiler as soon as possible for my elderly mother. Through her insurance my mother was given details of another company to complete the works. I wanted to have a look around to ensure my mother had an installation that was value for money and a company that was reliable and trustworthy. After looking at all the positive reviews for Gregor Heating on the Which Trusted Traders website it was a no brainer and by deciding to have the works completed by Gregor Heating was not disappointed. Right from the start, the experience with the whole team from the administration staff and surveyor Adam, right through to the installation team was First Class. On the day of installation the installer Craige M arrived first thing and worked through to early evening until the job was completed, even fixing a previous blockage in a radiator pipe that was not part of the works (that other private individual plumbers couldn't fix even though they charged my mother) so that radiator would work too. Craige was brilliant, he was cheerful, respectful of the Covid rules, very knowledgeable and professional in what he was doing and he got on with the job, cleanly & tidily ensuring my mother had heating and hot water again that day. I can not praise Gregor Heating enough and will definitely be recommending them. Thank you Craige & Gregor Heating for coming to my mums rescue.

We woke up on Thursday morning to a house warmed by an oil boiler and by early evening our brand new gas boiler was up and running. What more could we ask for? Craige pulled out all the stops and continued working until early evening to ensure we had a warm house on a winter's evening even after rain during the day. The remaining parts of the installation were completed the following day. Wales and West Utilities brought gas to our property on the Wednesday and Utility Warehouse installed a meter whilst Craige got on with his jobs. Well done all round, and full marks to Craige.

Tip top boiler replacement

We contacted Gregor Heating shortly after our boiler failed during a very cold snap in February. Initially we were given a surveyors appointment which was a couple of weeks away due to workload with the supplier, however, we did explain our position and an hour or so later Gregor phoned back with a cancellation. Adam the surveyor arrived the next day and gave us an inclusive price before he left which was followed up within an hour by email. We already had quotes from 2 local heating engineers. Gregor's were marginally less expensive, but their price included a first year complimentary service. We accepted their online quote and Craig our installation engineer arrived at 0800 to start work. His work was clean and tidy and he explained what he was doing throughout. A little later in the day Martin the ‘Sparky’ came the complete the Hive installation and explain its operation. The only job to be completed the next day was the installation of a soak away for the condense pipe. Job done. Thought all the visitors to our house were very aware of the COVID requirements Invoice for balance and registration of boiler arrived in email the very next day😉. I would thoroughly recommend this team and Gregors for you boiler replacement service. Thank you and well done 👍

I initially had a poor experience with Gregor Heating when the install of a new cylinder and conversion of system from vented to unvented system due to some unfortunate install issues. However, they resolved the issues and I came back to them to replace our failed boiler at short notice. Gregors worked really hard to turn everything around and my view has taken a complete U-turn. My experience with their sales team and the installer was very positive and I am very happy with the install of the new boiler and service. I would recommend Gregor Heating.

We self built 10 years ago but our original air source pump often gave us trouble and we have now had to replace it. From the start of this process, everyone at Gregor has been excellent. The initial advice and support instilled confidence and the week of the replacement was faultless. All the team were prompt, Covid aware and punctual. They worked efficiently and left the site clean and tidy each evening. The level of professionalism was impressive and they were all cheerful and friendly, working extremely well together. We have now decided to commission some more work from them to fit an electric vehicle charger and solar panels and would not hesitate to recommend them to anyone interested in alternative energy.

Writing here on a frosty Bristol 1° morning, it's toasty warm thanks to the boys and girls from Gregor. A. Adam, arrived on the Wednesday, prompt, smart and courteous, following all covid protocol and most importantly listened. Listened to my requirements on a replacement combi boiler, and gave me a quote that suited my needs. A quick turnaround appointment was made. B. Builder John had the graft of lifting up garden slab outside to accommodate excess boiler water. He done this without breaking it, and a professional job makes it look like his work has been there forever. C. Craige M was the front of shop... first in, last out main contact and installer we all hope to wish for. Punctual, polite, professional, quiet, respectful of my antique animals, and handy to answer all my silly questions. Also, really explained well to me, a dinosaur, thermostat options. Summary. After the Gregor advert board caught my eye at The Mem, from start to finish I am impressed with the service I received. What I found best was the no hard sale, I was a customer with knowledge of what I wanted and Gregor fitted in and around that. All delivered with respecting covid restrictions and confidence in their product, and installed by their own (rather sub contracted) team. If Gregor ever wanted to get into the dating game, can they deliver just as good old boiler as the new one I've received?!

From the first call to book a quotation to the final fitting of the boiler I experienced professional, timely and warm service. I never felt pressurised to go for a more expensive boiler, I felt their feedback was honest. When the boiler was fitted the technician Craig was fantastic and showed great attention to detail, he had a few problems but he worked through them to get the job done in a day. Only problem I had was trying to pay the final invoice, getting through on the telephone and the online payment option not working.

Gregor heating removed my broken back boiler and fitted a combi boiler. From quote through installation their service was very professional. I was pleased they insured on scaffolding for roof work for safety of the fitter. Other companies could take a risk On that aspect. They arrived on the date booked and completed on time. The fitter was tidy and informative. There was an issue with scaffolding breaking a roof tile but the team ensured it was fixed. Very pleased.
