About Us
One Team to Build, Heat and Power Your Property
Why hire a builder, a heating engineer and a solar installer when one team can do it all? Greentek brings building construction and renovation together with solar panels, heat pumps, battery storage and insulation. Because we plan everything as one job, the work happens in the right order: insulation goes in while the walls are open, cables are run before the plastering, and the heat pump is sized once the building is right. For you, that means less disruption, no work done twice, and a property that's cheaper to run from day one. It's why homeowners and landlords choose us as their energy efficiency company in the West Midlands and Wales.
Solar & Renewable Energy Solutions
We design solar PV, battery storage and air source heat pump systems around your property and the way you actually use energy, to help bring your running costs down.
