How well does solar work in London?
London has a lot of flats, terraces and conservation areas. Terraced houses are often well suited to solar, but if you live in a conservation area or a listed building, check whether you need planning permission. If you live in a flat, plug-in balcony solar may be the simplest option.
Covers Inner and outer London boroughs.
What does it cost?
Prices across England are fairly similar. A typical 3 to 4 kW system for a three-bedroom home costs around £7,300 installed, according to MCS data from February 2026, with no VAT to pay until 31 March 2027. See our full cost guide.
Grants and loans in London
If your household is on a lower income, your council may be able to fund solar panels through the Warm Homes: Local Grant. All homeowners should be able to apply for low and zero-interest loans under the Warm Homes Plan once details are published later in 2026. Check what you could get.
