Solar installers in South-East England.

By the numbers

South-East England sun, measured.

≈1,018–1,163 kWh per kWp a year, above the UK average

For every kilowatt of panels, a well-placed roof across South-East England generates roughly this much a year, with where you land in the range depending on your town, roof direction, pitch and shading. The roof check estimates it for your exact address.

Local context

Roofs across South-East England.

What South-East roofs tend to be like:

• Commuter-belt new-builds. Reading, Oxford, Milton Keynes and the wider Thames Valley have large estates of modern pitched roofs that install cleanly.
• Kent and Sussex heritage. Tile-hung cottages, oast houses and listed buildings are common. Older and protected roofs need a heritage check before any work.
• South-coast exposure. Portsmouth, Brighton and the coast see more wind and salt, so a survey confirms the right fixings and layout.

Grants & support

What help is available in South-East England?

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.
