Customer comment
"Very happy. Job done very professionally. Very high standard of workmanship, cooperative team of installers. Found them highly experienced in the field of solar and underfloor heating. I would highly recommend Complete Plumbing Clean Energy without any doubt.
We constructed a purpose built summer house at the end of the garden to accommodate the solar panels on the roof and the roof slope was recommended by our solar system installer to get the maximum output from the panels and also avoiding any shading. The panels installed are high output and start generating even on a cloudy day. They are manufactured by LG electronics and have proved to be performing very well. This has been one of the perfect installations. You are most welcome to verify the meter reading.""
