The only trader I'd recommend for the job

Mark did a combi conversion for me and I was delighted with the entire job in every way. The fitter was just perfect in how he did the job, he was kind, helpful and utterly cooperative. Everything was done on time and within the budget, and we had absolutely no problems with the work. I cannot think that any other company would do as well, he will be my only recommendation.

Gregor Heating are by far and away the best tradespeople I have ever used. The experience from start to finish was simply sublime. Our engineer Mark Gundrill was a very nice, friendly, approachable and socialable heating engineer that installed a fantastic combi boiler conversion. I would reccomend them without hesiatation.

I am always confident that any work carried out by Steve Gregor Ltd will be completed to a high standard and in a professional manner. My experience today was very positive as it was our Dual Engineer that has serviced our boiler for several years. He is very experienced and highly trustworthy and we couldn't be happier with the work carried out.

I needed to replace our gas boiler and I needed a company that would give me 24/7 cover. We have used British Gas homecare service for over 30 years and have been well satisfied with their service. This time I wanted to buy a Worcester Bosch boiler but unfortunately British Gas were not very competitive so I used Which? Trusted Traders and found Gregor Heating to be the one to suit my requirements. They sent a very nice surveyor to check over my heating system and recommend a suitable boiler and a written quote was received in the next 2 days. We paid a deposit and the gas engineer from Gregor’s arrived on the due date and time and all the necessary parts were delivered. The Gas engineer made a first class job of installing the boiler the same day-their electrician came in due course and did all the electrical connections-so everything was working OK by 4.00pm. A few days later their builder arrived to make good the ventilation pipe hole in the wall. We have a 30 year old Bradstone house and the builder, using one of my old Bradstone bricks made and excellent job of bricking in the hole and the mortar he used married in to perfection with the existing. When I looked the next day you would have thought it was part of the original build. Well done Gregor Heating-you carried out an excellent installation. I used to run a shop where we prided ourselves in the motto 'the shop where service and advice still counts'-this is equally true to be said about Gregor Heating.

We have used Gregor Heating on several occasions without a problem. In each case we have been offered professional advice and comprehensive quotations. The work carried out has been to a very high standard, the workplace left clean and tidy, and any refuse taken away, on the most recent occasion Gregor Heating suggested cost efficient solutions for the project and were flexible in how they worked with other work being undertaken around them.

I found them, from the initial enquiry stage, right through to an audit at the completion of the job, to be courteous, informative. Would carry out any survey or work appointment at the said time. That was the case from the office to the installation teams.
