The government is to legalise plug-in solar panels for use in homes across the UK in response to the Middle East crisis.
Plug-in solar panels are compact, portable modules that homeowners can install themselves – without the need for an electrician – in gardens, on walls or balconies and plug straight into a mains socket.
The devices were previously banned for use in homes due to safety concerns, with a potential fire risk warning due to compatibility with UK electrical systems and ring mains. It is unclear how or if this will be addressed before the ban is lifted.

It means families could potentially buy solar panels at the supermarket while doing their weekly shop. Supermarkets have yet to confirm if they will be stocking the cheap energy source when the ban is overturned.
Government announces plug-in solar plan
As part of a push to go “further and faster” in energy security, the Department for Energy Security and Net Zero confirmed in a statement seen by Homebuilding & Renovating that plug-in solar will be made available for households in the UK for the first time.
These panels, already popular across Europe, are designed to be easy to install without professional electricians and can feed electricity directly into a home’s mains wiring.
“Global events demonstrate there’s not a moment to waste in our drive for clean power because there can be no energy security while we are so dependent on fossil fuels,” said Energy Secretary Ed Miliband. “We are bringing forward the next renewables auction and announcing that plug-in solar will be available for the first time in Britain.”
Alongside plug-in solar, the government is accelerating its Warm Homes Plan and renewables auctions, aiming to get clean energy into homes faster and provide practical savings for households.
Why was plug-in solar previously illegal?
Plug-in solar panels were previously restricted under UK electrical safety laws, primarily because connecting a generator directly to a home’s mains wiring without proper certification could risk fire or electrical shock.
Unlike professionally installed rooftop systems, plug-in panels bypass the need for a certified electrician, meaning there were no clear safety standards or regulatory approvals for domestic use.
A government spokesperson said in December 2025: "Plug-in solar panels are not permitted because they must comply with existing electrical safety and wiring standards, and the government has begun a safety review to determine how they can be deployed safely."
Why the ban on plug-in solar is being overturned
Plug-in solar offers a low-cost, DIY-friendly option for homeowners who want to start generating their own electricity.
It’s particularly appealing for those with small gardens or outdoor wall space, where installing a full rooftop system might be expensive or complicated. By reducing reliance on the grid, these small systems can help cut electricity bills immediately, while contributing to national energy resilience.
Adam Bastock, founder of People, Planet, Pint, highlighted the convenience: “You can plug them straight into your wall. Buy a solar panel from a supermarket, hang it somewhere with sunlight, and plug it in like any other device. The biggest saving is there’s no need to get an electrician to install them.”
Cost comparison: Plug-in vs traditional solar panels
Using the latest Octopus Energy figures for professional rooftop systems, the differences become clear:
Plug-in solar
- Small systems (~400–800 W) cost roughly £280–£966 depending on capacity.
- Typical annual savings: £88–£210.
- Payback period: around 3–6 years, assuming you use the electricity as it’s generated.
- Low upfront cost, fast DIY installation, quick savings.
- Output is low compared to rooftop systems, won’t power a whole house, and safety standards are still being finalised.
Traditional rooftop solar
- A basic 2-panel system: £6,163 installed.
- Larger rooftop system with optional battery: £8,518–£9,691 (based on Octopus Energy figures)
- Potential annual savings: up to £600–£700+, with payback over 9–11 years.
- Higher energy generation can reduce most of a household’s bills, potentially earning through export Smart Export Guarantee tariffs.
- High upfront cost, requires scaffolding and certified installation, and longer lead time.
Therefore, plug-in solar is a quick, cheap entry point into home solar, while rooftop systems offer far larger savings and energy independence over the long term.
Is plug-in solar a good DIY option?
For homeowners and renovators, plug-in solar could potentially be an attractive first step if safety concerns are addressed. This is because:
- It’s low-risk and quick to install, perfect for a garden wall or small outdoor space.
- Ideal for budget-focused renovations where a full rooftop system is impractical.
- While it won’t replace the savings of a professional rooftop install, combining it with insulation, heat pumps, or other energy upgrades can significantly reduce household bills.
However, UK regulations for plug-in solar are being finalised, so systems must meet wiring and certification standards before use.
Ultimately, plug-in solar gives UK homeowners a fast, affordable way to start generating clean energy, while full rooftop systems remain the best choice for those aiming for maximum savings and long-term energy independence.
