How much do solar panels cost in Slough?

It depends on roof size, orientation and whether you add a battery, so we quote after surveying your property rather than publishing a Slough price list. Two figures help you judge value: domestic solar panels and batteries carry 0% VAT until 31 March 2027 (5% after that), and PVGIS estimates a south-facing 4kWp array in Slough generates about 4,120kWh a year. Under Ofgem's price cap for 1 October to 31 December 2026, the average electricity unit rate for Direct Debit customers in England, Scotland and Wales is 26.32p per kWh.
