What Telford homeowners actually pay
Telford was built as a new town from the late 1960s, so two-thirds of the housing stock is consistent post-war estates with standard concrete-tile roofs and off-street parking — among the easiest UK locations to install solar on. A typical 4 kWp install lands £4,800–£6,400 and produces around 3,660 kWh per year. The exceptions are the historic cores of Madeley, Dawley and the Ironbridge Gorge World Heritage area, where heritage scrutiny is significantly tighter.
