Solar Panels in Greater London
We connect homeowners across Greater London with MCS-certified solar installers. The capital's dense Victorian terraces, mansion blocks and post-war estates mean roof size and party-wall/overshading issues vary block by block — a site survey matters more here than almost anywhere else in the UK.
Solar generation in Greater London
According to PVGIS irradiance data for London, a typical 4 kWp south-facing system in Greater London generates around 4,000 kWh per year. At the April 2026 Ofgem price cap of 24.50p/kWh, that covers £980 of electricity you would otherwise buy from the grid.
On top of bill savings, surplus energy exported to the grid earns Smart Export Guarantee (SEG) payments — typically 4–6p/kWh with the main suppliers, or up to 15p/kWh with specialist tariffs like Octopus Outgoing.
A typical 4 kWp system with a 5 kWh battery costs £7,000–£11,000 installed across Greater London. At current energy prices, most homeowners break even within 8–10 years.
Local grid: UK Power Networks (London)
Every solar install in Greater London connects to the grid through UK Power Networks (London), who require a G98 notification for systems up to 3.68 kW or G99 approval (up to 45 working days) for anything larger. Your MCS-certified installer takes care of whichever applies, included in the price.
