Great Solar Panell Fitting team!

Sam and Jude and Darren were the most wonderful guys to work with. They were the electricians and the roofer responsible for fitting and getting our solar panels up and running. they were so polite, accommodating and considerate. So grateful to them for what seems to have been a smooth installation.

Good service

Up to installation day everything was excellent but we had issues with scaffolding and kit delivery. They got resolved but it was less than ideal. The roof team and the electrical team were outstanding, though, and delivered a great service.

Peter and Rio arrived on time

Peter and Rio arrived on time today, worked hard, very friendly and explained everything well getting things up and running. The rest of the team have been very good too, on time, did what they said they would do. Just a minor hiccup on communication between the office and installation team which resulted in a wasted journey for the installation team, but was quickly resolved. Would recommend Sustain Homes.

Solar panel and battery installation…

Solar panel and battery installation completed today, hassle free & went without a hitch.
The installation team were very good, friendly and conscientious, a very good service.
Of the whole process the only bit of feedback would be that the correspondence / updates by Sustain could be improved, keeping in touch more prior to installation.
Overall very satisfied with the process and service to date.

Professional and friendly

The points of contact with Sustain have been very professional and cordial. The design process with a little drawn out to find the optimal arrangement but the survey and installation teams were excellent. They were proactive when the installation team were affected by last minute sickness and when the removal of the scaffolding by their sub-contractor was delayed, to find a suitable time.

Max and Billy :5☆ Sparkys

Max and Billy arrived promptly and explained everything that they were going to do. From then on they worked diligently and consciencely until The PV system was successfully installed some 5/6 hours later. This work included digging a 5m trench in the driveway. Throughout they were both very polite, affable and ensured their boots were removed when coming in the house! They took me through the Foxcloud App, tidied up thoroughly and left a first class 5☆ days work behind them.

Solar panel installation.

Sam and Jude turned up punctually and undertook the task of wiring up the solar panels. The work was done neatly and efficiently and they happily answered the several questions that I asked.
More than happy to recommend them.

Absolutely faultless

Absolutely faultless. The communication, organisation and quality of the work has been beyond my expectations. The contractors who put up the scaffolding to the fitters and electricians arrived on time, were courteous, quick and did a great job. Above all this, the customer service from the centre exceeds anything I have experienced recently from any other industry, by a country mile. I would have absolutely no hesitation in recommending Sustain and will be telling all my friends.

Well planned and executed installation

Survey was very thorough. Installation went fine despite a few minor changes to timing (one engineer was ill). Fortunately I could be flexible in accommodating the changes.
Care and attention paid to reinstatement of paving slabs that needed to be lifted, and wiring done neatly.
