Basingstoke grew fast as a London overspill town and most of its housing is 1960s to 1980s estates with simple pitched roofs and small gardens: Popley, Brighton Hill, South Ham, Winklebury. Chineham, Hatch Warren and Beggarwood are newer, with more EVs on the drives and the garages that make a battery easy to site. Old Basing and the villages are a different job, with older roofs and some conservation-area and listed property.
The business parks around the town are large daytime loads with flat roofs, where commercial solar pays back in around five years and the Workplace Charging Scheme covers staff chargers at £500 a socket.
