The Solar Co provides residential and commercial installations of solar and battery solutions across London. We’re based in Bromley, and the majority of our installations are across London and the South-East.
We’re a ‘Which?’ trusted trader, and MCS-certified installers, so you can trust us to help with designing the right solar panel system for you. If you are looking to cut your electricity bills, or wanting to reduce your carbon footprint, get in touch with us today.
We are a London-based company, and not another nationwide company.
Being placed in Bromley, the majority of our jobs are done in London and the South-East.
Although we are local, we are not small. We are proud of our work, and would encourage you to take a look at both our Trustpilot rating and reviews on Google. Here are some additional reasons to choose us:
We assess your energy usage and roof structure to design the perfect solar setup for your home. Homeowners in London can save money and reduce carbon emissions with our solar PV systems.
From small retail units to large industrial sites, we design tailored systems to maximise your energy savings. Our commercial solutions can help reduce operating costs and improve sustainability.
We install EV charging points alongside solar panels, helping you make the most of your renewable energy, and lower the cost of motoring.
Further reduce your energy bills by storing excess solar energy. Using batteries can reduce your dependency on the grid when tariffs are the highest, helping you lower your energy bills.




We’re committed to transparent pricing with no hidden fees. Whether you’re installing solar panels on terraced housing, or a detached property, we provide clear guidance and upfront quotes tailored to your needs.
Domestic solar panel installation in London will typically range from £9,000 to £20,000. The cost doesn’t vary by borough, and instead the factors are:

A typical 8-panel south-facing solar PV system in London can comfortably exceed the annual electricity consumption of the average UK household, especially when paired with efficient energy usage habits and optional battery storage.
The breakeven period for a solar panel installation can vary depending on several key factors:
In ideal conditions — such as high energy consumption, a well-positioned roof, and battery integration — customers can achieve payback in as little as 4 years.
For homes with lower energy usage or less optimal conditions, breakeven typically falls between 6 to 9 years, with most London customers seeing returns around 6–7 years.
Battery systems, when combined with smart tariff management, can significantly accelerate ROI even in less-than-perfect conditions.
Here’s a recent installation we completed in the Bromley area:
System Size: 21 x 425W solar panels
Key Components: 8.8kW hybrid inverter, 21.28kWh of battery storage
Installation Type: Integrated panel system on a pre-tiled roof
Total Cost: £22,550 (including full system and installation)
Energy Output: 9,192 kWh annually
Roof Orientation: Combination of easterly and southerly aspects, across both pitched and flat roof areas
Estimated ROI: 19%
Estimated Payback Period: Just over 5 years
This project is a great example of how well-designed systems — even across mixed roof orientations — can still produce excellent results in terms of both energy savings and return on investment.
We evaluate your property, energy usage, and roof suitability to design the best solar system for your needs.
Our experts create a custom solar panel solution, optimising efficiency and savings.
Our MCS-certified installers handle everything from panel mounting to wiring, ensuring a smooth and efficient installation.
We provide aftercare services, including performance monitoring and system maintenance, to keep your solar panels running at peak efficiency.
London is made up of many boroughs, of which homeowners and businesses are starting to make the switch to renewable energy. At The Solar Co, we’ve completed over 100 plus installations across London postcodes, helping local residents reduce their energy bills and increase their energy independence.
Our London customers often highlight the following key benefits:

Yes. London is in the South-East which typically receives more sunlight than cities further north in the UK
Most homes in London do not require planning permission, but if you live in a conservation area, own a listed property, permissions may be needed. We can help guide you with this process.
Absolutely. Many of our London installations are on such properties. We design systems tailored to your roof shape, size, and orientation.
A typical London home needs roughly 15–25m² of usable roof space for a standard residential system. We’ll measure and assess this during your free consultation.
You’ll need freeholder or building management approval for a flat installation. For top-floor flats with roof access, individual systems may still be viable — we can explore options for shared systems too.
Rules are set nationally, but enforcement and interpretation can vary slightly by borough. We’re experienced with London councils and can handle any planning nuances for your area.
Yes — although there are advantages to doing the system all at the same time to plan the most effective solution.
Most residential installations take 1–2 days. More complex setups (e.g., integrated panels, battery systems, or split roofs) may take slightly longer — but we always aim for minimal disruption.
Yes — we’re based in Bromley and carry out the majority of our installations across Greater London and the South-East. As a local team, we understand London properties, and customer needs.
Savings depend on your energy usage and system size, but many households reduce bills by 50-70%, sometimes even more.
