The Short Answer
As of July 2026, no UK supermarket sells plug-in balcony solar kits. Aldi sells solar garden lights, IKEA sells full rooftop installations through a partner, and Lidl's well-known Parkside balcony kits are an EU-only product for now. That is about to change: DESNZ has named Amazon, Asda, B&Q, Currys, Lidl, Screwfix and Wickes as the retailers working with it on plug-in solar, and sales become legal on 27 August 2026. Note the direction of that sentence, though: sales become legal then, not now. Until 27 August 2026the government's position is that plug-in solar devices cannot be sold or used lawfully in the UK — so the answer to “where do I buy one today” is that you do not, from the middle aisle or anywhere else.
Why the confusion?
Aldi Solar Panels: Garden Lights, Not Power Systems
What Aldi UK actually sells under the "solar" banner is garden lighting — solar string lights, stake lights, lanterns and decorative pieces, typically £8–£15 through the Specialbuys range. These are lovely for a patio but they generate a trivial amount of electricity for their own built-in LEDs. They will not reduce your electricity bill.
Aldi's bigger UK solar story is on its own roofs: the company is installing panels across its store estate, with more than 500 stores expected to have rooftop solar by the end of 2026. That's corporate energy strategy, not something you can buy.
The interesting part is Germany. Aldi's German stores have sold complete 800W balcony solar kits as limited-run specials — priced around the €300 mark — and they sold out within days. Aldi UK has announced nothing, but the German precedent plus the UK government's retail talks make an eventual UK Specialbuys kit very plausible. When it happens, expect the classic middle-aisle pattern: limited stock, keen pricing, gone in a week.
IKEA Solar Panels: Real, But Rooftop Only
IKEA is the one retailer on this list that genuinely sells home solar in the UK today — just not the plug-in kind. IKEA first sold its Solstråle rooftop range here from 2017 before withdrawing it in 2019 when the Feed-in Tariff ended. In late 2025 it returned, launching home energy services through installer partnerships: solar panels, batteries and EV chargers supplied and fitted by Soly, and heat pumps from Aira.
This is a conventional, professionally installed, MCS-certified rooftop offering. A typical system runs from roughly £5,000 for a six-panel setup to £9,000 for a larger one, including installation. Because it's MCS-certified, it qualifies for the Smart Export Guarantee — something most DIY plug-in systems currently can't access.
If you own a house with a suitable roof, it's a legitimate route worth comparing against local installers. If you rent, or live in a flat, it does nothing for you — which is exactly the gap balcony solar fills. Worth noting: IKEA Belgium now offers plug-in balcony kits, so IKEA has the product line ready if the UK framework opens the door.
Lidl Solar Panels: The Parkside Kits Everyone's Heard About
Lidl is the supermarket most associated with balcony solar, and for good reason — in Germany and other EU markets it sells complete plug-in kits, from budget Parkside own-brand starter kits (around €199) up to premium EcoFlow bundles. None of this is available in UK stores.
Lidl GB has said on the record that it is "exploring the possibility" of stocking plug-in solar here, and press reports have floated a roughly £400 price for a basic kit. But nothing is confirmed — no launch date, no price, no product. The regulatory blocker is easing, though: in June 2026 DESNZ published a DESNZ interim product specification for consultation — a BS 1363 UK plug with a 5A fuse, an 800VA limit, one device per household — so retailers now have a concrete spec to certify a UK kit against even before the full BSI standard is published. We track the full picture — what's confirmed, what's speculation, and what German Lidl kits tell us about likely UK specs — in our dedicated Lidl plug-in solar panels guide.
What's Actually Coming to UK Shelves
The March 2026 DESNZ announcement that kicked off UK legalisation had a specific retail commitment: the government confirmed it is in active talks with major supermarket chains and a major DIY retailer to stock plug-in solar, with the stated ambition of kits sitting on shelves "alongside washing machines and dishwashers". No retailer names were confirmed. Our news analysis of the supermarket announcement covers who the likely candidates are and what Germany's rollout suggests happens next.
The full BSI technical standard (commissioned in March 2026) and the simplified DNO registration pathway are still not finished, but the interim product specification DESNZ published in June 2026 bridges the gap on the product side. The government is targeting a complete framework by the end of 2026, though the BSI standard may well slip into 2027 — see our UK regulations timeline for the current state of play. Realistic reading: first supermarket kits late 2026 is now plausible, with wide availability more likely 2027.
What to Do Before the Shelves Fill
We used to tell you not to wait for the middle aisle, and to buy a specialist kit instead. That advice was wrong, and we have withdrawn it. The government's position is that plug-in solar devices cannot at present be sold or used lawfully in the United Kingdom, as they do not comply with the Plugs and Sockets etc. (Safety) Regulations 1994 or the Electricity Safety, Quality and Continuity Regulations 2002. From 27 August 2026, SI 2026 No. 848 opens a lawful route — but only for a device that meets the final Interim Product Specification and has been verified as compliant on the ENA Type Test Register. Submitting a device for registration is explicitly not enough on its own. As at our last check of the register (11 August 2026), no kit had been verified. That applies to the specialist kits from EcoFlow, Anker Solix, APsystems and Hoymiles just as much as to anything a supermarket might stock.
What is worth doing now is groundwork. Compare the market in our round-up of the best balcony solar kits in the UK, read our guide to the legal status of balcony solar for the full position, check a specific kit against the rules with our compliance checker, and follow our certification tracker for the first kits to clear the register. DNO notification under G98 remains mandatory for any generation connected in parallel with the grid, supermarket-bought or otherwise.
The honest maths on waiting
A supermarket 800W kit might eventually cost £100–£150 less than today's specialist prices, and Germany's experience suggests discounter competition pulls the whole market down. That is a real argument for not rushing.
Be careful with the savings side of the sum. The reported government estimate is that plug-in solar saves £70–£110a year. An earlier version of this page put the figure at £100–£200 — that was our own estimate for a well-sited system, not the government's, and we used it to argue that waiting costs more than it saves. On the government's own numbers that argument is much weaker, and in any case the binding constraint right now is not price. It is that no compliant kit exists to buy.
Frequently Asked Questions
Does Aldi sell solar panels in the UK?
Not plug-in or rooftop panels — only solar garden lights and small decorative solar products via Specialbuys. Aldi Germany has sold balcony solar kits, and Aldi UK is a likely candidate to stock them once the UK framework is in place, but nothing is confirmed as of July 2026.
Does IKEA sell solar panels in the UK?
Yes — full rooftop systems installed by its partner Soly, from roughly £5,000 installed. No plug-in balcony kits in the UK, though IKEA Belgium sells them.
Does Lidl sell plug-in solar panels in the UK?
No. Its Parkside and EcoFlow balcony kits are sold in Germany and other EU markets. Lidl GB has said only that it is exploring UK availability.
When will UK supermarkets sell balcony solar kits?
The June 2026 DESNZ interim specification gives retailers a spec to certify against while the full BSI standard and simplified DNO registration are finished — late 2026 at the earliest, more realistically 2027 for wide availability.
Should I wait for supermarket solar panels or buy a kit now?
Neither, yet. Plug-in solar devices cannot at present be sold or used lawfully in the UK; from 27 August 2026 a device that meets the Interim Product Specification and is verified on the ENA Type Test Register may be, and none has been verified so far. On the savings side, the reported government estimate is £70–£110 a year — lower than the £100–£200 we previously quoted, which was our own figure. Use the wait to compare kits and check compliance, not to hurry a purchase.
