Local context

Solar in the Gatwick corridor: quick guide.

Redhill, Reigate and Crawley run in a line along the North Downs and the M23, and the housing mix shapes a solar install:

  • Reigate and Dorking period homes. The older town centres have Victorian and Edwardian roofs with steep pitches, plus conservation-area checks near Reigate old town.
  • Crawley new-town estates. Crawley's postwar neighbourhoods have consistent, simple pitched roofs that take panels cleanly and usually need no consent.
  • Horley and the Gatwick fringe. Newer estates around Horley and the airport edge add plenty of well-oriented modern roofs.
  • Surrey Hills and trees. Homes near the Downs get open sky, but mature trees are common, so a surveyor checks for shading through the day.
  • Get a survey. An installer survey confirms roof direction, condition and the right fixings before you commit.

Grants & support

Eligibility for grant schemes depends on your income, home and circumstances, and the schemes change. We keep the current picture on one page rather than guess what you'll qualify for.

Common questions

FAQs about solar around Redhill & Reigate.

Do I need planning permission for solar panels around Redhill and Reigate?

Most domestic solar installations are permitted development, so no application is needed. The exceptions are the Reigate old-town and Dorking conservation areas, listed buildings, and homes on the North Downs inside the Surrey Hills National Landscape, where roof-facing panels can need consent. A local installer knows the Reigate & Banstead, Mole Valley and Crawley council positions, and a survey confirms suitability first.

How much does a solar installation cost around Redhill and Reigate?

Prices here track the UK average. A typical 4 kWp system lands in the £5,000 to £7,000 range installed, with battery storage adding roughly £3,000 to £6,000. Solar and battery are zero-rated for VAT until 2027. The on-roof survey gives the firm figure for your home.

Do the Crawley new-town estates suit solar?

Often very well. Crawley was built as a postwar new town, so its neighbourhoods have lots of semis and terraces with simple, consistent pitched roofs that take panels cleanly and usually need no consent. The older Reigate and Dorking homes vary more, with steeper period pitches and some conservation checks. A survey settles direction, condition and fixings for your specific roof.

Which areas does this page cover?

This page covers the Gatwick corridor from east Surrey across into Crawley: Redhill, Reigate, Betchworth, Dorking and Horley (RH1 to RH6) plus Crawley (RH10 and RH11), one continuous built-up corridor along the M23 and Brighton main line. Horsham, Burgess Hill, Haywards Heath and East Grinstead are distinct mid-Sussex towns and are kept separate.
