Sustain - Solar, Heat Pumps & HomePlans Avis 

Sustain get full marks for their product (a 15 panel solar and battery installation) but very low marks for their flaky customer service and considerable installation delays.

From initial survey on 7 April it took exactly four months to completion. We had obtrusive scaffolding for four weeks, the solar installation took one week, not the one day scheduled and promised return calls were frequently missed.

Sustain’s polite but ineffective office staff often overpromised and underdelivered. Although told that a single person would deal with my installation, many other staff became involved making it confusing to try to get any prompt or effective action.

I’ve tried to help Sustain by speaking in a constructive way with the MD. Having been promised a fast track to completion, I have since asked for an apology for yet another delay of a fortnight in producing the final simple invoice but none has been received.

Sadly I cannot recommend Sustain given my long suffering experience.

We were very pleased with the solar installation carried out by Sustain. The installers did a great job and dealt with unexpected with no complaint. Site left tidy and they gave a full explanation of app and system.

Sustain Homes did a good job with surveying and installation of our solar system. The only reason for not giving a 5-Star rating is because unavailability of scaffolding caused a week's delay with the installation as it appears that information about the property having a conservatory wasn't shared with the scaffolders. It would be useful for the scaffolders to have all photos showing front and back elevations of properties.

Sustain installed a ten panel system yesterday the team of two were polite and professional. They worked real hard despite the heatwave weather, I was impressed. They explained everything about the system before they started. The install was much quicker than I expected and after setting up the app for me and explaining all its functions, they cleaned up and removed all rubbish from my property. The whole experience with sustain has been a positive one from the initial enquiry call and all the follow up communications to the courtesy call this morning to see how everything went and give me information about what happens next. Everyone I have spoken to at sustain have been professionally friendly and super helpful. I would most definitely recommend them.

One of the few companies I found willing to do an install on a flat roof. Once the survey / structural process had been done I got an install date really quickly. The install was seamless with little disruption and we were generating electricity within 2 days.
Can't fault the process.

Great communication throughout, competitive price. I chose this company as they seem to be well established and have great reputation.

Installation went smoothly. Electrician explained everything throughout and guided through the app at completion. Aftercare communication is spot on.

Would definitely recommend.

Very professional installation your fitters Antonio and ash where excellent the arrangements for clearing up a bonus would recommend you to anyone

First class service and installation. Was very happy with the advice I got from the sales team and the install was super smooth and very professional.

The project was completed and all parts coordinated by Sustain the only issue with the project was the considerable delay from the Distribution authority that Sustain helped overcome.

Ran into some problems with solar panel installation, Sustain reacted quickly and resolved problems and installation came in on track.
Can thoroughly recommend their service

The whole team, from the sales, support people and the installers were brilliant.

The four lads from Sustain worked very hard for two days from 8am till 8pm, replacing our heat pump system, without stopping, they were very professional and did a excellent job, we would highly recommend them to anyone, well done and thank you.

Excellent after installation support

Very professional company excellent service

Good contact

Excellent service from start to finish. Colum was professional, knowledgeable, and kept us informed throughout the whole process. The installation was completed to a very high standard, everything was left clean and tidy, and we’re delighted with the end result. I wouldn’t hesitate to recommend Colum and the team. Five-star service!

My installation has failed. I reported this two weeks ago. Many promises to call back, all did not materialise. They seem unwilling to visit and honour the warranty.

Great company very informative with any questions I asked and very helpful.
Highly recommend company.
