From initial contact through to completion and after care, SW3 have provided a faultless service. As a family run business, they really care. Communication was great throughout the process. They responded to any queries/requests promptly and attended appointments when they said they would. Installation was extremely efficient, all done in one day. Nick the roofer and Will the electrician worked efficiently and cleanly throughout the day and Will took great pains to ensure trunking in the house was as unobtrusive as possible. He took time to explain the complicated installation to us so that we understood it and installed the apps on our phones, talking us through how that worked too. This could have been a daunting project for us, but SW3 ensured the process was simple. Wouldn't hesitate to recommend them.

I really wasn’t sure about having solar panels fitted. I had heard of the benefits, but it is expensive and a real faff, so when I contacted SW3, I was unsure. I needn’t have worried. Paul took care of all the forms, and although I stored the materials for a couple of days, installation was completed in less than a day. If I had a question (and I did), Paul would always call me straight back with advice on how to communicate with energy companies. Very happy I chose SW3.

Excellent Job, Couldn’t Be Happier with the Victron Setup

I’m really happy with how the Victron system installation turned out. The installer did a fantastic job, everything was finished perfectly, and you could tell they genuinely cared about getting it right. They paid attention to the small details and didn’t rush through anything. What stood out most was their willingness to go the extra mile. They took the time to troubleshoot and make sure everything was set up and working exactly as it should. It gave me a lot of confidence in the system and peace of mind knowing it was done properly. Overall, I couldn’t be more satisfied. If you’re looking for someone who knows what they’re doing and takes real pride in their work, I’d highly recommend them.

Installation of Solar Array & Battery

Fantastic service from the team. Paul initially came round and made recommendations on equipment but they were very accommodating when I specified the exact panels and battery which lead to a competitive quote and installation. I was communicated with throughout and knew exactly what was going to happen and when. Where they really stand out for me is the overall service and endless patience shown by Chris to answer my numerous questions as I try and optimise the system. Very happy to support this family business

I recently had a roof and solar panel installation completed by SW3 Green Energy Services, and I couldn't be more pleased with the results. Paul, Chris understood our needs and make everything clear and the team were incredibly efficient, adhering strictly to the schedule and even finishing the project ahead of the due date. Their professionalism and teamwork were evident throughout the process. I highly recommend their services to anyone considering roof and solar panel works. Excellent job!

SW3 diagnosed a problem with our existing PV system, inverter quoted for a replacement plus battery and carried out the installation. All appointments were kept, options were explained clearly and the work was carried out on the agreed day to the agreed price with no add-ons. All queries were answered promptly. It was a pleasure doing business with all their personnel.

SW3 prides itself on being a local, family run business which recognises the importance of professional integrity. In my experience it lives up to that ideal. Father and son, Paul and Chris were thorough in surveying our property and energy use and recommended a system suitable for my needs...and my roofs. Paul is a great advocate for solar but there was no hard sell (unlike my former electricity supplier) and Chris was clear on dates, timings and what to expect. Scaffolding was erected in advance to allow a thorough inspection of our roof and enable some re-felting. The installation team was led by electrician, Jamie. He and his team worked exceptionally hard throughout the day. Jamie was assiduous in his attention to detail and all his wiring work was completed neatly. Jamie gave a thorough explanation of how to use the websites that monitor battery and inverter use . The final sign off certification was completed by return and Chris monitored the system remotely for a week before requesting the dismantling of the scaffolding. All in all SW3 led by Paul and Chris have been outstanding from start to finish. They have carefully chosen their installation teams to ensure they provide high quality work. The installation is complete and generating power but Paul and Chris have been clear that they on hand to answer any queries I might have.
