Gregors Heating removed an old back boiler and installed a new Worcester boiler in our loft. As well as this, they also installed a loft light, moved some pipe work and added shower piping with no issues, and a clean finish. Would definitely use again.

Repaired a gas fire (which a previous company hadn't been able to do), and have serviced both this and our boiler, for the last four years. The gas engineer is always on time, and is very professional and courteous. He is extremely knowledgeable. He is always very helpful, and takes time to complete the job properly. The office staff are also very professional and the price quoted is always the same as that on the invoice. Excellent company - highly recommended.

Workmen seem to do a very competent job, but office staff are not very helpful. I felt they did not understand the nature of our problems, and the company makes absolutely no effort to hold onto customers; customer service is awful – we were completely misled into believing they wanted to sort out a problem with our heating as a gesture of goodwill, but then got presented with a massive bill – price quoted went up 50% in 6 months; then up again by 33% in the space of 6 weeks, whilst waiting for appointments and items to arrive! Very expensive and we feel totally underwhelmed by the way we have been treated.

Replace our hot water tank. The company seems well organised with good paperwork (printed and email) and tracked the progress of the quote to completion well. Fitted us in at short notice as a gap came up in their schedule. Took excellent notice of the house by laying sheets on the stairs to prevent carpets being marked.

Had a new combi boiler fitted which was done both to time and cost. All staff involved, the receptionists, the person who came and estimated the job, the person who fitted the boiler, the support staff including those who did the electrical work and repaired the the damage caused by the fitting were all very friendly, professional and extremely competent in their approach to the work. Unfortunately two small installation problems, which were nothing to do with the boiler itself, occurred within a week of the new boiler being fitted, both of which were fixed the day after I reported them. To say am I am pleased with the work this company has carried out for me is an understatement. I just wish the professionalism and work ethic of this company was reflected in other companies I have dealt with, even the boiler fitter turned up half an hour before the time he was scheduled to start, so I have no hesitation in recommending this company to anyone else wanting this kind of work carried out.

Replaced Combi-boiler. All staff involved were polite, helpful & professional. Installation was carried out with minimum disruption and care was taken not to damage existing fixtures & fittings as old boiler was in an awkward place to remove. I'm very happy with new boiler and the efficient & no mess installation.

From the time of my first enquiry to Gregor Heating, to the completion of my replacement boiler installation, everything was first-class - from the helpfulness of the lady I spoke to when I first called for a quote, Adam when he visited to give a quotation, Wayne when he called to undertake a survey, then finally (and especially) Craig when he undertook the installation. An excellent all-round job from a professional team.
