Mcs certified solar & battery installers · London
Solar panels. Battery storage. Smarter energy.
Design-led solar PV and intelligent home battery systems for London properties - specified around your home, your energy usage and your future.
London-based engineers. No high-pressure solar sales team.
Trusted by Leading Brands
Renewable energy expertise backed by an established London electrical contractor.
SOLAR DESIGNED PROPERLY.
Solar designed properly.
Solar is not simply about fitting as many panels as possible onto a roof. A good design starts with understanding the property: available roof space, orientation, shading, existing electrical installation, household consumption, electricity tariff and how energy requirements could change in future. Switched On London designs complete solar PV and battery systems for London homes, combining renewable technology with the electrical engineering experience needed to integrate it properly. From initial design and grid-connection requirements through to installation, commissioning, MCS certification and handover, the project is managed as one complete electrical installation.
Build an energy system around your home.
Our Solutions
Generate electricity, store it, use it intelligently and reduce how much energy you need to buy from the grid.
SOLAR PV
Generate your own electricity.
High-performance solar panels designed around the available roof space, orientation, shading and household electricity requirements.
BATTERY STORAGE
Keep more of your energy.
Store surplus solar generation for later or charge from the grid during suitable lower-cost periods.
EV CHARGING
Put solar in your tank.
Integrate compatible smart EV charging with your solar and home energy system.
HOME BACKUP
Stay switched on.
Compatible battery systems can be designed with backup capability to provide power during certain grid outages.

TECHNOLOGY WE TRUST
Brands we love.
We're not tied to one manufacturer. The right equipment depends on the property, available space, energy usage, tariff, required battery capacity and what you want the system to achieve. But there are some technologies we particularly like working with.
SIGENERGY SIGENSTOR
One intelligent ecosystem for home energy.
Premium modular solar, battery, backup and energy-management technology.
DURACELL ENERGY
Flexible home battery storage.
Suitable for storing solar generation and/or using smart time-of-use tariffs.
WHY SWITCHED ON LONDON
Solar installed by electricians. Not salespeople.
A solar and battery system isn't simply equipment bolted to a roof. It becomes part of the home's electrical installation. That's why we approach every project as an electrical engineering job first. Our designers consider the whole system - consumer units, earthing arrangements, protective devices, cable routes, export requirements, inverter and battery location, monitoring, EV charging and future electrical demand. The result is a solar installation designed around the property rather than a standard package designed around a sales target.
MCS CERTIFIED
Designed and installed within the applicable MCS framework.
NICEIC APPROVED
Electrical contracting is at the core of the business.
GRID CONNECTIONS
Relevant G98/G99 requirements managed as part of the project.
COMPLETE HANDOVER
Testing, commissioning and applicable installation documentation.
ONE CONTRACTOR
Solar, batteries, EV charging and associated electrical work.
LONDON SUPPORT
An established local contractor after installation day.
WORKMANSHIP
A great solar installation isn't just what you see on the roof. It's everything you don't.
Use large real photographs of the electrical detail. This is a key point of difference versus online solar-sales brands.
THE ARRAY
designed around usable roof areas.
CABLE MANAGEMENT
protected, considered cable routes.
AC & DC PROTECTION
correct isolation and clearly identified equipment.
ENERGY GATEWAY
integration between grid, home, solar and storage.
THE DETAIL
electrical engineering behind the installation.
ENERGY STORAGE
finished Sigenergy SigenStor installation.
LONDON HOMES
Designed for London roofs.
London homes rarely provide one enormous, unobstructed south-facing roof. Victorian and Edwardian properties frequently include extensions, dormers, rooflights, chimney stacks, flat roofs, different orientations and shading from neighbouring buildings. That is not necessarily a problem - it simply means the system must be designed around the property.
FLAT ROOFS
Purpose-designed mounting systems can make otherwise unused roof space productive.
MULTIPLE ORIENTATIONS
East, west and south-facing roof areas can sometimes be combined within an appropriately designed system.
COMPLEX LONDON PROPERTIES
Rooflights, extensions, limited plant space and cable routes are considered as part of the initial design.
BATTERY FEATURE
Generate it by day. Use it when you need it.
The home does not necessarily use electricity at the same time solar panels are producing the most power. Battery storage allows surplus generation to be stored for later. Compatible smart battery systems can also make use of suitable time-of-use tariffs by charging during lower-cost periods. We size solar and battery storage together around likely energy use rather than assuming the largest battery is automatically the best one.
RECENT PROJECT · SOUTH WEST LONDON
Making multiple London roof spaces work together.
This South West London property presented exactly the type of challenge regularly seen in the capital: multiple available roof areas rather than one large uninterrupted pitch. The solar installation was distributed across the usable roof space and integrated with a Sigenergy SigenStor battery system, creating one complete home-energy solution.

FAQS
Solar Panel Questions, Answered.
Solar PV can work very effectively in London. Likely performance depends on factors including roof area, orientation, shading, panel specification and household electricity consumption. We model the proposed system before recommending an installation.
