Call our Team

We are different

Eco7 are not your typical solar PV and energy storage company. We do not employ sales agents, we do not cold call customers and do not have doorstep canvassers. Instead, we use the power of the internet to advertise our services, and all the enquiries we generate are passive. That is to say, people only find us when they are looking for something and not because we have canvassed them with direct marketing. By keeping our operation trim, and by not employing sales agents, we can keep control of both pricing and protect our reputation by ensuring we offer the very best levels of service and after-sales care. It is why we have a 100% positive feedback rating, and why we are ranked #1 on TrustPilot in the Solar PV category.
