Excellent boiler installation
Gregor Plumbing and Heating recently fitted our new boiler. We had a number of quotes but we went with Gregor because from the start you could tell they were different. The engineer who came out to assess and offer the quote was courteous, professional and friendly. He didn’t try any hard sell or try to sell us something we didn’t need. A date was agreed when to fit the appliance that was favourable to us. They were on time, efficient, professional and explained everything as they worked through the day. Once installed they tested the boiler, taking time to explain how it worked. Cleaned up after themselves and removed the old boiler and packaging. 1 year free service also provided. I highly recommend this company.

Highly efficient servicing of the boiler

The annual boiler service was carried out with the usual efficiency I have experienced with Gregor over many years. The person who came had been before, a very nice man who gave high praise of the actual boiler and its workings. He suggested advice on how we can treat it even better and make it work better for us - e g, don't have it set too low or it just cools down, wasting gas! I promised to tell the 'gas fairy' who is the one who mucks about with the controls. Concerning the price, I already knew what to expect and at £90 inc vat it was perfectly reasonable.

Advice and subsequent Fitting of New Combi Boiler by Gregor Heating, Electrical and Renewable Energy
Customer Service
Quality
Value
We chose a suitable date and time for us. They arrived on time and conducted the work in a professional manner. It was impressive to see that the new boiler arrived in readiness for fitting by another provider. The plumber (Connor) was excellent throughout the fitting. He coordinated with the delivery of the new boiler and the electrician to appear and undertake his side of the fittings as and when he was required. There was no down/wasted time in waiting for any aspect. The briefing on the new boiler was undertaken without any hassle. It was a pleasure to have had the work undertaken and all materials were taken offsite, again without hassle. Prior to this we had a recce by the Installation Manager who advised us as to what we required to fit our needs and he was also very knowledgable and helpful. The support from the firm with paperwork, payment etc. has been exemplary and could not outline any problem/s with the process. I would classify this firm as a traditional old world firm who do what they say they will do with no hassle to the customer - a rarity in today's modern age! I would strongly recommend this provider.

Our house is not straightforward and although on paper we were just having a replacement boiler in practice it meant dealing with complicated plumbing where the system had been added on to by various builders over the year. We now have a much better system and an airing cupboard not entirely filled iwth pipes. Gregor were helpful and frank in the planning for the work, people always came when they said they would. Craig who did the installation was amazing and very patient with our endless questions, and working around our requirements as we both work from home some of the time. When we had a slight problem the following week someone came out the next morning to sort it out for us. I would highly recommend them.

All of the team at Gregor Heating have been amazing, from the initial servicing visit to Adam's new boiler survey and the 2 great installation engineers who fitted the boiler and tested everything. They took a lot of the pressure and worry out of the situation and got us back up and running within a week. Thank you!

We had a new oil boiler and cylinder system fitted and the service and experience was first class from start to finish - from making intial contact and Chris coming round to carry out the survey, communication thereafter and through to conclusion via Debbie was very efficient, polite and professional. No hidden costs and paid exactly what I was quoted at the start. Connor and Josh who installed the new boiler system were also excellent. Fast, efficient, turned up each morning when they said they would, worked hard and Connor explained exactly what was happening, what they were going to do next at each step through to conclusion. We discovered a minor leak issue the day after completion, informed Debbie, and Connor came round to rectify it in no time at all - great service. I would highly recommend using Gregor to anyone considering having similar works done.
