Andover, like Basingstoke, grew as a London overspill town, and its housing is mostly 1960s and 1970s estates with simple roofs, plus large new estates at Picket Twenty, Augusta Park and Picket Piece where most houses have a drive and many have an EV. The town centre has a small conservation area; the surrounding villages, from Whitchurch to Ludgershall and the Bourne valley, are on rural supplies where a battery with backup is a sensible addition.
Andover sits between Salisbury and Basingstoke, both of which we cover, so it is a regular run rather than an outlier.
