By the numbers

London solar, measured.

Typical yearly generation, per kW of panels

≈1,029 kWh per kWp a year — roughly 10% above the UK average

For every kilowatt of panels, a well-placed London roof generates about this much a year. Your own total depends on roof direction, pitch and shading — the roof check estimates it for your address.

Local context

Solar in London: quick guide.

London sits at the top of the UK for solar irradiation — the South-East gets more usable sun than almost anywhere else in the country, so the underlying economics are strong. The complications in London are rarely about sunshine and almost always about the building: roof access, ownership and conservation rules.

A few London-specific things to think about:

  • Terraces and roof aspect. A huge share of London homes are Victorian and Edwardian terraces. A rear roof facing a south-leaning aspect is typically the strongest candidate — front roofs may face conservation-area restrictions.
  • Flats and shared freeholds. Solar on a flat usually needs the freeholder's consent and often the other leaseholders'. The roof may be communal. Worth checking your lease before you get too far.
  • Conservation areas. London has more conservation areas than any other UK region. Panels visible from the street can need consent in swathes of Camden, Islington, Kensington & Chelsea, Greenwich and beyond. A local installer will know which streets need paperwork.
  • Access and scaffold. Narrow streets, parking bays and party walls can make scaffolding more involved than in the suburbs — which can nudge the installed cost up. Get it priced explicitly in your quote.
  • Battery storage. With time-of-use tariffs widespread in London, battery economics are usually worth running through the savings calculator.

Grants & support

What help is available in London?

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.

Common questions

FAQs about solar in London.

Do I need planning permission for solar panels in London?

Most domestic solar installations in London are "permitted development" and don't need planning permission. But London has an unusually high number of conservation areas and listed buildings — much of Kensington & Chelsea, Camden, Islington, Greenwich and the City fringe — where front-facing or street-visible panels can need consent. Rules also vary borough to borough. A local installer will know your street.

How much does a solar installation cost in London?

London installer prices sit at or slightly above UK averages — typically around £1,300 to £1,800 per kWp depending on system size, access and components. A 4 kWp system usually lands in the £5,000–£7,200 range. Battery storage adds £3,000–£6,000. Scaffold and restricted access on terraced streets can push labour up.

Are London terraced houses and flats good for solar?

Terraces often are — a rear roof on a south-leaning aspect is a strong candidate even on a narrow London plot. Flats are more complicated: on a shared freehold you'll usually need the freeholder's and other leaseholders' agreement, and the roof space may be communal. A survey settles it.
