Find Out If UK Plug-in Solar Will Save You Money
Calculate your likely annual savings in under a minute, then see which legal plug-in solar kit gives you the fastest payback.
Traditional solar isn't right for everyone
Many people want lower electricity bills but can't justify a £7,000-£14,000 rooftop solar installation.
If you rent, live in a flat, or simply want a lower-cost option, plug-in solar may now be worth considering.
The difficult part is knowing whether it will actually save you money.
Plug-in Solar Kits in the UK
Plug-in solar kits are the fastest way to start generating your own electricity in the UK without scaffolding, drilling, or a long wait for an installer. A typical plug-in setup uses one or two rigid 400–465 W panels on a secure balcony bracket or ground frame, wired to a plug-in microinverter or an all-in-one unit like the EcoFlow Stream.
From 27 August 2026, plug-in panel microgenerators up to 800 W will be legal in the UK under the new SI 2026/848 regulations. That means a compliant plug-in solar kit can be plugged into a normal UK socket and run in parallel with the grid. Read the regulations summary.
The best plug-in solar kits for UK renters and flat owners are modular: You can even start with a single panel and add more as your budget allows, and you can take the whole system when you move unless you have fixed to a roof.
