What we install

Our services in London

Solair covers homes in London, with a focus on the south west boroughs closest to Surrey, such as Kingston upon Thames and Richmond upon Thames. Every job starts with a free survey, after which you get a fixed, written price. For solar panels and batteries, we also handle the paperwork with your electricity network operator.

Who handles planning in London

London has 32 borough councils plus the City of London, and each one is the local planning authority for its own area. So if you live in Twickenham, your council is Richmond upon Thames. If you live in Surbiton, it is Kingston upon Thames.

For most houses, roof solar panels and air conditioning outdoor units do not need planning permission. Air-to-air heat pumps, which is what home air con is, became permitted development in England on 29 May 2025. The catch in London is how much of it is protected. Richmond upon Thames alone has 72 conservation areas and Kingston has 26, and some streets also have Article 4 directions that remove permitted development rights. Listed buildings always need consent. Council guidance in both boroughs generally prefers panels and units at the back or side, out of view from the street.

Houses, flats and hot summers

London’s homes range from Georgian and Victorian terraces to Edwardian villas, 1930s semis and modern flats. Terraces often have a usable rear roof slope or a back extension roof, which suits solar well. In flats, the roof and outside walls usually belong to the freeholder, so you will normally need their written consent before any outdoor unit or panel goes up, and planning rules for flats are tighter than for houses.

Cooling matters more here than in the countryside. On one August day in 2023, engineering firm Arup measured central London at 4.5°C hotter than its rural surroundings. Brick terraces and top floor flats can hold that heat well into the night, which is why many Londoners now look at home air conditioning.

Electricity network and costs

Most of London is served by UK Power Networks, while some parts of west London, such as Feltham, are served by SSEN. Whichever operator covers your address, Solair sends the notification for a solar or battery install. Residential solar panels and batteries also carry 0% VAT in Great Britain until 31 March 2027.

FAQs

Questions from homeowners in London

Do I need planning permission for solar panels in London?

Usually not for a house, as most roof-mounted solar is permitted development. Listed buildings need consent, and many London streets sit in conservation areas or under Article 4 directions, so it is worth checking with your borough council first.

Can I have air conditioning in a London flat?

Often yes, but the outside walls and roof usually belong to the freeholder, so you will need their written consent first. Flats also have tighter planning rules than houses, so we check this at the survey.

Which electricity network covers my London home?

Most of London is served by UK Power Networks, and some parts of west London are served by SSEN. Solair handles the solar and battery notification to whichever one covers your address.
