From 27th August 2026, it will be legal to self-install plug-in solar systems in UK homes.
Set to revolutionise access to solar generation, these off-the-shelf kits will typically consist of up to four solar panels, a microinverter and a standard UK plug that simply plugs into a socket in your home.
The panels generate free solar energy, which can be used to help power your home and reduce the amount of electricity you need to buy from your energy supplier. They are likely to have wide appeal, but could be particularly suitable for people who don’t have access to a suitable roof or the capital required for a larger solar installation.
How much can I expect to save?
It is estimated that a typical household could save around £70–£110 per year, with greater savings possible for households that use more electricity during the daytime.

Plug-in batteries are not included in the new legislation, and you cannot currently sell any excess electricity you generate back to the grid.
Kits are expected to retail from around £400 upwards, offering a reasonable payback period compared with some other energy-efficiency improvements.
What is permitted under the new legislation?
The government has approved systems of up to 800 watts. This has the potential to generate around 2 kWh per day during peak summer months.
You can install and plug in the system yourself, with no electrician or additional wiring required. Safety cut-outs are also included to ensure that the plug is never “live” when it is disconnected from the socket.
It is highly recommended that you consider having an Electrical Installation Condition Report (EICR) carried out by a qualified electrician, particularly if your electrical installation is old or has been altered in any way.
You do not need to inform your electricity supplier, but each installation will need to be notified to your District Network Operator (DNO) using a G98 form.
Where can I buy one?
Several retailers are preparing to launch off-the-shelf products, ranging from high-street supermarkets and DIY stores to specialist online retailers.
With plug-in solar becoming more accessible, it could provide a simple way for households to generate some of their own electricity without the cost and complexity of a traditional rooftop solar installation.
