That was installed by Greenscape Energy. Suffolk Coastal Council ran a bid campaign where they negotiated for all the residents who asked for a quote. I know costs went up post covid & with the rising power costs.
Many thanks, Yes, my council ran a similar thing under the Solar Together scheme, using Infinity Renewables as the installer. I've no issues with the quality of the installation, but I could never get a plausible demonstration that this was lower cost than anybody else doing it. In the end though maybe the planet will melt a smidgeon more slowly than it would have done.....
