Truro’s centre is Georgian and Victorian, built around the cathedral in local granite and roofed in Cornish slate. Much of it is a conservation area and many buildings are listed, so Cornwall Council is the first call before any panels go on those roofs. Outside the centre the housing is simpler. Post-war and later estates such as Malabar and Highertown have plain roofs. The newer homes at Threemilestone and Langarth have drives for a charger and space for a battery.
Cornwall is narrow, so few homes are far from the sea and salt air reaches well inland. That shapes the choice of fixings and where the inverter goes. Large parts of the county sit in the Cornwall National Landscape, formerly the AONB, where the rules for wall and ground-mounted panels are tighter. Rural homes are on long overhead lines run by National Grid Electricity Distribution, so a battery with backup is worth asking about. Truro is well beyond 90 minutes from Ferndown, so the first survey is a video call, then a grouped site visit.
