From my first enquiry through to the completed installation, Tony and the team at We Know Energy provided an excellent service. Communication was outstanding throughout the whole process. They took the time to answer every question, explain the different options, and share their knowledge and experience, giving me complete confidence that I was making the right decisions for my battery installation. The installation and commissioning were completed to an exceptionally high standard. The workmanship was first class, everything was left neat and tidy, and nothing ever seemed too much trouble. It was clear that they take real pride in the quality of their work. What has impressed me just as much is the aftercare. Even after the installation was complete, Tony has been on hand to answer questions and help me understand the inverter settings and system setup. That level of ongoing support has been invaluable and really sets We Know Energy apart. I would have no hesitation in recommending Tony and the team at We Know Energy to anyone considering a battery or solar installation. Professional, knowledgeable, reliable, and genuinely committed to delivering a great customer experience from start to finish.

Tony, Alex and David are an incredible team. So thorough, professional, knowledgable and friendly. They installed solar panels and a battery in my house and did a fantastic job. 10/10 recommend.

This project took a long time as we worked through getting a fully functional smart meter, planning approval, moving over to Octopus Energy and finally the construction of a plinth for the domestic batteries to stand on. Tony stayed patient throughout and got on with the job the very moment all was in place. We have 15kW Libbi batteries and 5 Solarwatt panels combined with a Zappi EV charger which have made charging our EV so much more convenient and most importantly massively cheaper. The work he, David and Alex did was perfect - neat, efficient and Tony stayed on the case as we spent time getting the hang of the apps and charging schedules - which took a week or two! They were great guys to work with; we would have absolutely no hesitation in recommending We Know Energy to anyone embarking on a project like ours.

Professional, personable and straight forward. Tony and Alex did a great job installing our solar panels on our garden room. They even advised and made good of some less than ideal wiring left by the previous owners. Battery and new inverter next! Would not hesitate to recommend!
