We had no power to any of our thermostats when the engineer arrived. He checked all the obvious areas, but with persistence he discovered the fault in the UFH control panel, it was rectified, next he exchanged a defective thermostat, result being all 'stats' working, and from our point if view we have warmth again. Thank You Gregor

Gregor Heating Solar and battery installation Couldn't be happier with the work carried out fitting solar panels and batteries. All Gregor employees were helpful and always ready to answer questions. They arrived on time, carried out the work and cleared away all rubbish. Would definitely recommend.

Excellent service I’ve been a customer of Gregor’s for several years - always happy with the service provided. The ladies on the telephone are always charming and helpful, and the service engineer who regularly services my boiler is extremely pleasant and professional. A great service all round!

Annual Servicing Central Heating/Gas Fires Very good annual servicing yet again from Gregor Heating. Work is always carried out with care, tidiness and efficiency. Customer is always advised what is being done and why. Annual maintenance contacts are good value and give peace of mind-not the cheapest,not the dearest but probably one of the best. Any call outs/emergencies are always handled promptly-benefit of using local company with local knowledge and local staff on call-out/standby rotas. Back-office staff always prompt your annual servicing appointments and deal with any follow ups with courtesy.

Worcester Boiler service and Landlord Gas safety check on Boiler and Gas hob Booking: Following reminder text from Gregory (very helpful) the office staff were extremely helpful and offered various dates to book gas boiler service and safety check. The engineer arrived at the expected day and time and Phil was very accommodating regarding may various questions and interest in how things worked- clearly he is highly experienced. The service/safety checks/testing was all completed without drama (and there was no attempt at any up-selling). Payment was completed on-line through the web site - again no issues to report thus far! Excellent service. No hesitation to recommend!

First class service start to finish. Darren arrived slightly early, but that was fine with me. After a very friendly introduction, I went through our heating system with him and the problems being encountered. It was very reassuring that he immediately seemed to know what the problems were and set about fixing them. He appeared very knowledgeable. In a very short space of time, he had our heating up and running. I have used Gregor before, and on both occasions, I found that from the initial contact on the phone through to the engineers coming, this company is very friendly and professional. I have absolutely no hesitation in recommending Gregor from the experience I have had with them. They are brilliant!!
