UK Government Announces Plug-in Solar Panels Coming To Shops Within Months

LONDON - In a landmark move to accelerate clean energy adoption and cut household electricity bills, the UK government has confirmed that plug‑in solar panels - often referred to as "balcony solar" - will be available in shops across the country within months, marking a significant shift in the nation's approach to small‑scale renewable energy generation.

The department for energy security and net zero (DESNZ) announcement on march 24, 2022, is part of a broader clean energy package announced in March 2022 in response to growing energy security issues arising from the conflict in Iran. This has caused an increase in global fossil fuel prices, significantly increasing future domestic energy prices. The clean energy package also contains specific measures for implementing the future homes Standard that would require new homes constructed in England to have either solar panels or low carbon heating installed as standard.

Plug‑in solar panels, which can simply be placed on a balcony, terrace, or in a garden and plugged directly into a standard three‑pin mains socket, have already become a common sight across mainland Europe. In Germany, where they are affectionately known as Balkonkraftwerk (balcony power plants), approximately half a million new devices are installed every year, and over 426,000 systems were registered in 2025 alone. In Spain, too, the technology has gained significant traction.

However, until now, UK regulations have effectively prohibited their use. British electrical safety standards and grid connection codes were not designed to accommodate electricity flowing into a home's system via a standard socket, which is typically intended only for power output. That is about to change.

The government will be working with the energy networks association, distribution network operators and ofgem (the energy regulator) to review and amend the existing g98 connection code for connection to the distribution network. The G98 connection code is the connection standard for solar PV systems and therefore will be revised in accordance with the existing electrical wiring regulation BS7671, to enable consumers that wish to install plug-in solar systems up to 800W (i.e. less than 0.8kW) to connect to their homes through existing 230V domestic mains sockets, rather than through the use of a qualified electrician, and under agreed (and tailored) safety standards. Regulatory changes are expected to be implemented as of Summer 2026.

The government is actively collaborating with major retailers, including Lidl and Amazon, alongside solar manufacturers such as EcoFlow, to bring these products to the UK market. Officials have suggested that shoppers could soon see solar panels appearing in the "middle of Lidl" aisles and other high street outlets.

Initial price estimates suggest that a typical 800‑watt plug‑in solar kit could retail for around £400, with some smaller single‑panel systems expected to cost considerably less - mirroring the affordability seen in Germany, where a comparable system can be purchased for approximately €280.

Lorna Wallace‑Smith, Head of UK Communications for EcoFlow, expressed optimism about the rollout timeline: "Allowing plug‑and‑play solar is a very positive step for expanding access to renewable energy. Seeing these systems available in stores by summer would be a major win for households."

For the millions of UK households struggling with persistently high energy bills - the Ofgem price cap currently stands at £1,641 for the average annual dual‑fuel bill - plug‑in solar offers a compelling financial proposition.

According to DESNZ estimates, a typical UK household using a plug‑in solar system could save between £70 and £110 per year on electricity bills. With an upfront cost of approximately £400, this means a family could recoup their initial investment in around four years. The panels reduce the amount of electricity drawn from the grid, particularly during daylight hours, thereby lowering bills and helping to insulate households from volatile fossil fuel market fluctuations.

Perhaps the most transformative aspect of the policy is its potential to democratise access to solar energy. Traditional rooftop solar systems - which typically cost around £6,300 to install and require professional fitting - are simply out of reach for millions of people who rent their homes, live in flats, or lack suitable roof space. The Energy Saving Trust estimates that a conventional 3.7 kW system can cost about £6,300 to install in London, offering an 11‑year payback period.

Plug‑in solar, by contrast, is fully portable, requires no permanent installation, and can be set up on balconies, against walls, or on garden sheds. This makes it particularly suited to the estimated 285,000 flats with balconies in England alone, as well as the millions of households in rented accommodation who have previously been excluded from the benefits of solar generation.

British Gas, one of the UK's largest energy suppliers, has welcomed the development. In a recent customer update, the company noted: "Plug‑in solar panels are particularly suited to renters, flats and small homes, as well as balconies and small gardens, and anyone wanting a low cost, low commitment way to start generating clean energy. Place them on a balcony, terrace, shed roof or outdoor space. Connect the plug‑in solar inverter into a standard three‑pin socket. Start generating your own electricity, which you can use instantly to power your home - so you don't need to buy as much electricity from the grid."

Energy Secretary Ed Miliband has framed the initiative as a cornerstone of the government's strategy to achieve energy sovereignty. "The Iran war has once again shown our drive for clean power is essential for our energy security so we can escape the grip of fossil fuel markets we don't control," Miliband said. "Whether through solar panels fitted as standard on new homes or making it possible for people to purchase plug‑in solar in shops, we are determined to roll out clean power so we can give our country energy sovereignty."

Retailers have added their voice to this call for action as well. Georgina Hall, Corporate Affairs Director at Lidl UK, commented that Lidl supports the government's move to make it easier to implement environmentally friendly technology, "The government's action is a huge step forward in assisting consumers to control their energy costs and help the UK achieve its goal of reducing carbon emissions."

Greg Jackson, Founder and CEO of Octopus Energy, noted that interest in solar has surged by 50 per cent since the beginning of the conflict in the Middle East. "People want to be free of these fossil fuel crises. Every solar panel, heat pump and battery cuts bills and boosts Britain's energy independence."

The plug‑in solar announcement is just one component of a wider government push to decarbonise the UK's energy system. The long‑awaited Future Homes Standard, which has now come into force, will ensure that the majority of new homes are built with solar panels and clean heating systems rather than gas boilers. Officials estimate these measures could save families up to £830 per year on energy bills compared to a home with an Energy Performance Certificate rating of C, while cutting carbon emissions by at least 75 per cent compared to homes built to the 2013 standards.

Additionally, the government has announced an innovative trial that will allow energy companies to offer discounted bills to customers in Scotland and the East of England on windy days, rather than paying wind farms to switch off when the grid cannot accommodate all the power they generate. This trial will run from April to June 2026.

With regulatory changes expected to take effect by summer 2026, British households could soon be joining their European neighbours in harnessing the power of balcony solar. If market uptake mirrors that of Germany - where around half a million new devices are installed annually - the UK could see up to 450,000 plug‑in solar systems sold each year, adding as much as 360 megawatts of new solar capacity annually. This would represent three times the current rate of traditional home solar installations.

For millions of renters, flat dwellers, and homeowners seeking an affordable entry point into renewable energy, the arrival of plug‑in solar on high street shelves cannot come soon enough.
