Fantastic service all round
Great service from beginning to end. Every phone call and interaction was pleasant, friendly and helpful. Scaffolders came and went without any issues. The team that fitted the solar panels was fantastic, did a great job, were careful and considerate in their work and took the time to make sure I understood the installation and the app. I have to say probably the best team I've had doing work at my property. All in all, no stress or hassle at all, I'm a very happy customer! Thanks team!

Polite, professional and friendly. No time wasting
Jamie, Leon and Josh all turned up on time. They where polite, friendly and professional. Unfortunately the equipment couldn't be placed as agreed with the surveyor due to a lack.of space. The guys did a really good job, no mess left, no time wasting on the job. Helpful with the app etc.

A very professional company
A very professional company, from the office staff, the fitters and the engineers. Had a follow up visit from Dan Hartley today, he answered all of our questions and did a very professional and thorough check of the system. We know if we did have any problems then a quick call to the office and they would sort it. Excellent after care service. Highly recommended.

Almost 5
The survey got the panel calculations wrong but this was fixed by the guys who put the panels up, and the panel guys were excellent. The electricians that wired the equipment were also excellent. The kit itself feels excellent. The scaffolders were not so good. One postponement was described to me by the main contractor as “What can I tell you? They just didn’t turn up”. They also caused damage to a flat roof that the scaffold sat on. The controls are via an app on your phone and it looks good. However, the user manual lacks detail and has some complicated redundancy/duplications in it that cause issues. Optimising overnight, cheap electric battery charging with EV charging took me about over a week to figure out a work around for, that shouldn’t really be necessary and upsets the “virgo” in me. That said, even though I couldn’t get the access to the controls I wanted, the after sales care is fast and friendly and hopefully future app updates will improve the particular issue I had.

Thank you for taking the time to share such detailed feedback. We’re pleased to hear that the panel installation team and electricians delivered excellent work, and that you’re happy with the kit itself and the app’s design.
We sincerely apologise for the issues you experienced with the scaffolding team, including the missed appointment and damage caused to your roof. This is certainly not the standard we expect, and we’ll be addressing it with the contractor to prevent it happening in the future.
It’s great to hear that our after-sales team was able to assist you quickly and positively. We’re committed to making your experience as smooth as possible and truly value feedback like yours that helps us improve.
Thank you again for your detailed review and for giving us the opportunity to improve.

A good experience and a positive outcome.
The whole process was professional and well executed for a good result.
The office staff were very helpful.
The roofers did a good job of fitting the solar panels, despite the poor weather.
The electricians also did a good, courteous job.
Only 2 comments.
I was surprised the planning was for 2 rows of 6 panels. The roofers thought the same and went for 3 rows of 5, 5 and 2.
There was inconsistency on where the inverter would go. The proposal said inside and the plan for the electrician said outside. It went outside.
But those 2 comments aside, it was a good experience.

Overall, we’re very pleased that, aside from these points, your experience was a good one. Thank you again for choosing us and for your thoughtful feedback.
