Local context

Solar in Slough, Windsor and Maidenhead: quick guide.

The SL districts sit along the Thames west of London, and the contrast between historic Windsor and the newer estates shapes a solar install:

• Windsor conservation and listed homes. Central Windsor has a large conservation area and many listed buildings near the castle, so panels on prominent roofs there can need consent and careful siting.
• Slough and Maidenhead estates. Slough and Maidenhead are full of interwar and postwar houses with simple pitched roofs that take panels well and usually need no consent.
• Larger homes in Ascot and the Bucks fringe. Ascot, Marlow and Gerrards Cross add bigger detached houses, often with generous, well-oriented roof space and room for battery storage.
• 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.

Grants & support

What help is available in Slough?

Solar and battery installations across the UK are currently zero-rated for VAT until 31 March 2027 — a straight saving on the installed price for every household, with no application needed. In England, ECO4 and the Warm Homes scheme can help eligible lower-income households with energy-efficiency measures through their energy supplier or local council.

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.
