Local context

Solar in Twickenham and south-west London: quick guide.

The TW districts follow the Thames through south-west London, mixing historic riverside homes with broad suburban estates, and that shapes a solar install:

• Georgian and Victorian riverside. Twickenham, Richmond and Teddington have period houses near the river, some listed or in conservation areas, so panels on prominent roofs there need extra care.
• Suburban semis. Hounslow, Isleworth and Feltham are full of interwar and postwar semis with simple pitched roofs that take panels well and usually need no consent.
• The Spelthorne edge. Ashford, Sunbury, Staines and Egham add newer estates and detached homes with clear, well-oriented roof space.
• East or west still works. A south pitch does best, but an east or west roof spreads output across the day and performs well across the area.
• Get a survey. An installer survey confirms roof direction, condition and the right fixings before you commit.
