What Peterborough homeowners actually pay
Peterborough is largely a planned new town — Bretton, Orton, Werrington and Hampton all built post-1970 with consistent housing, off-street parking and standard pitched-tile roofs. Combined with good east-England irradiance, this makes it one of the easier UK cities for solar. A typical 4 kWp install at £4,400–£5,600 generates roughly 3,640 kWh in year one and continues for two-plus decades with only routine inverter servicing in the middle of system life. Central PE1 around the cathedral is the main exception. Fast.
