Solar Panels in London
Solar panels on London homes
London has far more variety than most cities. Victorian terraces, interwar semis, mansion blocks and new flats all sit side by side. Because each type has a different roof, each needs its own approach.
Terraced roofs are often narrow, so a smaller array may fit. Flat roofs are common on extensions and blocks, and they suit panels tilted on frames. London is also among the drier, sunnier parts of the UK, so good output is realistic wherever shade is low.
Housing across London
Hackney and Islington have many Victorian terraces, and plenty of them are split into flats. While a split house can still take panels, the roof usually belongs to the freeholder. Ask about ownership before you pay for a survey.
Lambeth and Southwark mix terraces with estates and blocks. Wandsworth and Greenwich have long runs of Victorian and Edwardian terraces, plus interwar suburbs on the edges. Since roofs vary so much, a street-by-street survey beats any general advice.
Planning, flats and the grid in London
Most houses can fit roof panels under permitted development, even in a conservation area. However, listed buildings need consent, and some boroughs use Article 4 directions that remove these rights in certain streets. Phone your borough planning team before you order if you are unsure.
Flats raise a second question. If you rent or hold a lease, the freeholder usually owns the roof. You therefore need their written agreement. Shared roofs sometimes suit a single array that serves several homes.
UK Power Networks runs the grid for most of London, and your installer handles the connection paperwork. Check your own network operator on the energy network map if you live near a borough edge.
Costs and support for London households
Prices depend on roof access, scaffolding and system size, and scaffolding on tall London streets can cost more. Our guide to solar panel costs shows what to expect and how to read a quote. VAT on fitting in Great Britain is 0% until 31 March 2027.
Support for solar has moved on. The Warm Homes Plan, published on 21 January 2026, promises help for lower-income households. Councils will deliver much of it. ECO4 was due to run until 31 December 2026 with no new funding, so ask whether your supplier still accepts applications.
The Greater London Authority and boroughs have also backed group-buying schemes in the past. Check whether a round is open before you buy alone.

London solar: common questions
Do I need planning permission for solar panels in London?
Most houses can use permitted development, including many in conservation areas. However, listed buildings need consent, and some streets have Article 4 directions, so check with your borough first.
Can I fit solar panels on a flat in London?
Often yes, but you need permission from whoever owns the roof, usually the freeholder. Ask your managing agent early because the process can take time.
Who connects solar panels to the grid in London?
Your local network operator approves the connection, and UK Power Networks covers most of the capital. Your installer normally files the notification or application for you.
Which London areas can you cover?
We aim to cover every London borough, including Hackney, Islington, Lambeth, Southwark, Wandsworth and Greenwich. Send your postcode and we match you with installers that work there.
Are flat roofs in London suitable for solar?
Yes, in many cases. Panels sit on tilted frames, and the installer must check the roof load and the waterproofing. Flat roofs have their own height limits under permitted development, so ask about those too.
Is it worth fitting solar in London?
It can be, because London gets plenty of daylight and power prices are high. The answer still depends on your roof, your daytime use and the quote, so compare more than one.
