Portsmouth is the most densely built place we cover. The Victorian and Edwardian terraces of Southsea, Fratton, North End and Copnor have narrow but often well-oriented roofs, and a 2.5 to 3.5 kW system is the usual answer. Cosham, Drayton and Farlington on the mainland are 1930s and post-war semis with more roof to work with. Old Portsmouth and parts of Southsea are conservation areas where placement is planned with Portsmouth City Council first.
A large share of the city rents or lives in flats, and that is where the EV chargepoint grants earn their keep: £500 a socket for renters and flat owners with a parking space, and £500 a socket for landlords. Salt air means marine-grade fixings, as it does in Poole.
