I'm very pleased that I went ahead and replaced my old storage heaters with the new Dimplex ones. The whole process went smoothly and efficiently and Greenvision were very helpful at all stages and didn't rush me. Apart from working better than the old ones they also look smart, as does the new bedroom panel heaters. The installers did a brilliant job and didn't leave a trace.

Quality service for installation of a new Dimplex Quantum storage heater, Rointe electric towel rail, updated fuse box and all associated. The service provided by Greenvision went beyond all expectations. Everyone was extremely helpful and friendly. Stuart and Paul provided professional advice based on what would be best for me. The virtual survey option was ideal, so we could discuss options and get a quote straight away, which meant from contacting Greenvision to installation was only a couple of weeks! Amanda was great in keeping me up to date about the installation and arrangements. On the day, Dan arrived exactly when expected and fitted everything perfectly, it's made such a difference. Thank you to everyone at Greenvision. Very impressed and wouldn't hesitate to recommend!

I found Greenvision very pleasant to work with. The explanation of the product, and the survey to check it was suitable for my home were both excellent. The engineer was courteous and efficient, although I would have loved it if he had vacuumed before he left. I'm very pleased on the whole.
Purchase and installation of Dimplex Quantum Storage Heaters. Very professional from start to finish. In contact throughout. Answered questions and were friendly and helpful. Fitters were very efficient and even brought a hoover to clear up afterwards! They explained everything regarding usage. Very polite and professional from start to finish. Would recommend.

I instigated my business with Greenvision 6 weeks or so ago. The staff at Greenvision were informative, considerate of my needs and quick to answer any queries. Adjustments to my advantage were made after a survey which have proved to be most adequate. The installation occurred on 16th. January. The engineers were on time, efficient and considerate, clearing up and tidying up as they proceeded. They took time to make sure I understood the basics of operating my heaters. I will certainly recommend Greenvision where and when I can. So quick.

I used Greenvision for purchase and installation of 2 electrical high heat retention heaters for use with Economy 7. Everyone at Greenvision was friendly and helpful. Although based in Nottingham they facilitated installers for me in London. The whole process was seamless, quick and efficient. I would certainly recommend this company.

Supplied and fitted 3 Dimplex Quantum storage heaters. Used Greenvision because other residents in our retirement flats recommended them from their experience. They were right to do so as our experience was the same. From start to finish our experience was seamless and efficient ,polite, friendly are words that come to mind. The team that arrived with us on installation day was Nathan/Paul and Luker. All three were cleanly dressed, polite and friendly but courteous. They were very competent indeed and represented an excellent image of the Company. J B and L Lomas SANDBACH
