★★★★★

"We had a 6kW solar PV system installed on our south-facing roof last spring. The whole process from survey to switch-on took just three days. Our electricity bills have dropped by nearly two-thirds, and we are now earning from the Smart Export Guarantee on top. Best home improvement we have ever made — wish we had done it years ago."
