What our customers say
Real reviews from homes we've fitted.
A big thank you to Chris, Paul, and the whole team at SW3 Green Energy Services Ltd! A couple of months ago, I had a 15-panel solar system installed, complete with microinverters and a Powerwall battery. I'm already seeing real savings, especially with being able to make the most of off-peak rates and getting good returns from my energy provider's export rates.
What really impressed me about SW3 Green Energy was their reliability and professionalism. They were on top of everything from the first quote to the final paperwork. My setup was a little complex, with specific requirements around the placement of the Gateway and Powerwall, plus integration with my Zappi EV charger. They handled it all seamlessly.
Even when my energy provider botched the smart meter installation, leaving my system down, Chris came back to sort things out and got it up and running again.
Stellar experience from start to finish. Chris, Paul, Sherri and anybody on their team has been extremely competent and nice to deal with. They inspected my property, provided a detailed survey suggesting a sensible setup, with good explanations about how it would all work together and they provided a very reasonable quote, with highest quality materials. By the end of the day they were able to get all my apps set up and properly configured with the energy provider.
SW3 installed an excellent system to our home and provided exceptional service. They prioritise customer satisfaction. They strived to meet even our bespoke requests and their rates are fair. Kudos to Chris for the wonderful process from the initial discussion til post-installation, and for always keeping me updated. Kudos also to Matt who installed our system and who was really hardworking and knowledgeable. I would definitely recommend SW3 to everyone.
