Why solar panels make sense in London
Favourable conditions for solar energy
London offers reliable conditions for solar generation. According to data from the Global Solar Atlas, the specific photovoltaic power output for London is approximately 1,022 kWh/kWp. This indicates strong performance potential for rooftop systems in the capital.
Consistent output despite cloud cover
Despite London's mixed weather, modern solar panels operate efficiently using daylight rather than direct sunlight.
London has a diffuse horizontal irradiation level of 576 kWh/m², which represents the scattered sunlight that still reaches the ground on cloudy days. This means panels continue generating electricity even on the overcast days that are common across the UK.
Rising energy prices
With UK electricity prices remaining elevated, producing your own renewable energy is one of the most reliable ways to reduce long-term energy costs. A well-designed system can offset a significant share of your household consumption.
All installers we work with are fully MCS-certified, so your system will meet SEG requirements.
The Smart Export Guarantee (SEG)
Homeowners can earn payments for surplus electricity fed back into the National Grid through the Smart Export Guarantee (SEG) scheme. To be eligible, your installation must be commissioned by an installer certified by the Microgeneration Certification Scheme (MCS) or an equivalent body such as Flexi-Orb.
Public support and incentives
Solar panels benefit from 0% VAT on installation, helping lower upfront costs. This tax relief runs until March 2027, making now a good time to take advantage of the saving.
Some London boroughs also offer additional grants, community energy programmes, or sustainability initiatives that can further improve the overall return on investment.
Solar panel uptake across London
Homeowners in London are increasingly turning to renewable energy to power their properties and reduce their carbon footprint. This growth is part of a wider national shift toward energy independence and self-generation.
More than 60,000 London homes powered by solar
According to the Department for Energy Security & Net Zero, 60,113 domestic solar installations were operating across London as of September 2025. This data confirms that solar technology is now a mainstream and proven solution for London households.
Common solar system sizes for London homes
For a standard semi-detached home in London, a typical solar installation ranges from 4 kW to 6 kW. Most homeowners can expect costs of £6,000 to £10,000, depending on roof complexity, panel type, and system design.

Solar panel questions for London homeowners
Do solar panels work in UK weather?
Yes. Modern PV (photovoltaic) technology works using daylight rather than heat or direct sunshine. This means panels continue generating electricity on overcast days, making them well-suited to London's variable weather.
How much does a solar panel system cost?
Most residential solar panel systems cost between £6,000 and £10,000.
The final price depends on the system size (kW output) and the complexity of your roof installation. Factors such as difficult access, the need for scaffolding, or slate tiles may increase installation costs.
How long do solar panels last?
High-quality solar panels typically come with 25-year performance warranties. In reality, many systems last 30 years or more with minimal maintenance, providing decades of low-cost or free electricity.
Do I need planning permission for solar panels?
In most cases, installing solar panels on a residential roof in London falls under Permitted Development, meaning no planning permission is required.
However, rules differ for listed buildings, flats, and properties within conservation areas. A certified installer will advise you on any property-specific requirements.
