What Crawley homeowners actually pay
Crawley is one of the easiest places in the south-east to install solar. As a planned post-war new town, the housing stock is overwhelmingly post-1950 semis and detached homes with simple pitched-tile roofs, off-street parking, and almost no conservation-area restrictions. A typical 4 kWp install lands £4,600–£5,800, generates around 3,820 kWh per year, and pays back inside 9 years. Larger Maidenbower and Pound Hill detached homes often fit 5–6 kWp with battery for £8,500–£11,000.
