My mother's backboiler broke down. A tricky problem as l live one hundred and thirty miles away. Recommended by a neighbour, Gregor heating promptly came to the rescue. The repair was helpfully and pleasantly organised by Darby, Kate, and Michelle and the engineer Trevor collected a new part and did the repair. We were delighted and of course relieved - many thanks.

We had a back boiler which we wanted to be replaced urgently. During the quotation survey Chris Cox talked us through the various options, taking into account what would work best for our house. His information was very helpful for us to understand what our options were and the works included removing the back boiler, installing a gas combi boiler, and replacing all the pipework and radiators. He also recommended a smart thermostat and I'm very grateful he did because I find myself enjoying it immensely now that I'm using it daily. Amazingly, he managed to book us in for the following week and the entire job was completed in 3 days, for which we are extremely grateful. The installers Mark and his colleagues were super friendly, professional and took great care whilst working in our home. Given the major job they had to do, I'm very impressed with how tidy they left everything.

We had our annual boiler service today and was again impressed by the time and care taken to do a thorough service. Phil, the engineer, arrived on time and was very pleasant to deal with. He explained as necessary the tests he was undertaking, and the results obtained. All gave me great confidence that the boiler was continuing to work efficiently. Very pleased with the support provided by Gregor and recommend their services.

Installation of air source heat pump

We met three key people from Gregor Heating and Renewables. They were all extremely efficient, knowledgeable and highly capable - and they were really good at their trade. The surveyor who oversaw the installation, the planner who worked out the detailed specs and applied for all the paperwork, building regulations and government grant, and the engineer who fitted it all in our home. Everyone was really friendly too and went to great lengths to explain how we control our new heating system. Gregor installed a Daikin air source heat pump, a new high pressure tank and new radiators and pipes throughout the house. We are delighted with their work and very happy with the end product.

Rob and his colleague did an excellent job in identifying problems and getting our neglected system back in order. One identified electrical fault remains but this rectification work is promised soon.

Thoroughly unsatisfactory
We have a new build house on an estate where Gregor Heating has been the main plumbing and heating contractor. We have had a number of snagging issues and have experienced ongoing prevarication from Gregor's tradespeople attending to address the problems. The worst is a washbasin problem for which we have had four visits to our house without a satisfactory resolution, and even following the complaints procedure has so far failed to resolve it. The manager from the estate development company supports us and agrees the problem requires fixing - perhaps the fifth attempt may bring and end to this sorry saga. It is not an isolated incident as a previous engineer attended when we reported a problem with stiff shower valves. He informed us that the problem was insufficiently serious to meet the manufacturers' threshold for a complaint. So we went direct to the manufacturers with support from the estate development company. The manufacturers' engineer came out quickly and replaced two faulty valves without question.

New Boiler Purchase & Installation

We have a service plan with Gregor Heating & have also had a boiler from them in the past at a previous property which we were very happy with, so naturally when our old boiler needed replacing we turned to Gregor for help. They looked after us from start to finish; we had the boiler area surveyed to ensure we had a compatible boiler replacement and kept us within budget without compromising on boiler efficiency. On the day, the engineers were so kind & helpful. They did the job with care & attention with minimal disruption & nothing was too much trouble. We changed our mind on which wall controllers we wanted on the day of install - from battery operated to electric - the engineer rang the office & a member of the Gregor team drove over especially to deliver them. The job was finished on time. The engineers showed me how to operate the boiler and wall switches before they left & didn't leave until they were happy I understood the process. The day couldn't have gone any smoother. The boiler comes with a 10 year Guarantee and we have peace of mind that Gregor will be there to assist with the maintenance/should we need to call them out.

New Boiler

The heating system in our new house was old inefficient and, frankly, a dog’s dinner. Those who came to quote huffed and puffed when they realised it was not a straightforward job. Not so Gregors and, as we had used them in our old house, we used them again. We were not disappointed. Craig, their engineer, did a great job. His installations were straight and neat and old holes filled in. Everything was left tidy and the remnants of the old system taken away before he left site. He kept us informed of progress and answered our questions, otherwise he worked without fuss. My one complaint is the Home Owner’s Gas Safety Certificate sent later. It reads as if a dangerous appliance is present. I phoned Gregors and was told that everything is fine and if we sell the house, a solicitor would know how to read the certificate; well, it will never get the Crystal Mark for plain English. Twice I have asked for a quick email for my records confirming all is fine, but over a month later still no email.

Having originally contacted Gregor Heating in early February and received a quotation for work as requested, I then accepted the quotation and paid a 50% deposit with an agreed start date of 17 March. Thereafter, the Installation engineers arrived at 7.15 am and on discovering the previously visited site and utility room installation location promptly walked off site! Over the next 4 weeks, following the departure of 2 Gregor works quotation personnel! ,who had been dealing with my work request, and zero response to several emails I eventually got through to Gregor Heating personnel whose response and knowledge of this accepted work was bordering on incompetent. After a threat of job cancellation and demand of my deposit back I was quickly contacted by a Gregor Heating manager. A short and frank exchange was had and thereafter a 3rd visit was made to the property and a start date of 25 April was agreed. The work then proceeded on time however, the Engineer did apologise on the 1st day for not having all the correct items for installation due to an order mix-up. The work was completed over 2 days as originally quoted. Finally, the epitome of the total lack of customer service shown by the company is that not once have they got my name correct on any piece of paperwork and I have told them on 4 separate occasions...this continues with the Worcester-Bosch boiler Guarantee arriving by email today with my name wrong yet again!
