Plug-In Solar Panels UK: The Complete 2026 Guide

Yes — plug-in solar is legal in the UK, as of 27 August 2026. Statutory Instrument SI 2026/848 removed the previous requirement for a qualified electrician and MCS (Microgeneration Certification Scheme) certification for small "plug-in solar" kits — a solar panel plus microinverter that connects through an ordinary 13A wall socket, no consumer unit rewiring involved. The detail most headlines skip is that legality is granted device by device, not brand by brand: a kit is only lawful to plug in if its specific microinverter model is listed as "Compliant" on the ENA (Energy Networks Association) G98 Type Test Register at connect-direct.energynetworks.org. As of 28 August 2026 that register shows eight compliant devices in total — all seven UKSOL Ltd kits plus the Perlight PowerPlug MAX 465 — and nothing else. Everything below explains what plug-in solar actually is, what the five UKSOL kits cost and save, where you can buy one today, and the registration and safety steps the new rule still requires.

What is plug-in solar and how does it work?

A plug-in solar kit is two things bolted together: one or more solar panels, and a small box called a microinverter that sits between the panel and a standard wall socket. The panel produces DC electricity; the microinverter converts it to 230V AC and feeds it straight into your home's ring main through the socket, where it's used by whatever's drawing power nearby — a fridge, a router, a kettle — before any surplus goes to waste. There's no battery in the loop and, under this interim rule, there isn't meant to be: a plug-in kit only exports live generation while the sun is on the panel. It cannot import electricity from the grid, and it cannot store what it makes for use after dark. If you want stored power, you're looking at a different, MCS-certified category — see our plug-in solar vs rooftop solar comparison for how the two setups actually differ in practice.

The number that matters more than anything printed on the panel itself is the microinverter's AC output cap: 800W. That's a hard technical ceiling on every plug-in solar device sold under SI 2026/848, regardless of how much panel is wired to it upstream. UKSOL's biggest kit, the Pro Max, carries 1260W of DC panel — but its microinverter still only ever pushes a maximum of 800W of AC into your socket, because the inverter clips anything above that. The interim spec also caps combined DC panel rating at 2,000W, so you won't see a single household plug-in device with more panel than that, at least for now. In practice the 800W ceiling matters far less than the panel's orientation or shading — the "extra" DC capacity mostly buys you a fuller 800W output for more hours either side of solar noon, not a higher peak. If you're weighing a wall mount against a balcony rail, our balcony solar panels UK guide covers mounting options in more depth, and because no wiring work is involved, plug-in kits genuinely don't need an electrician to install — full detail on what that does and doesn't cover is in do plug-in solar panels need an electrician?

Is it actually legal today — check the register, not the marketing

"Legal since 27 August 2026" is true, but it's a statement about the law, not about any specific product on a shelf. The rule created a pathway; only ENA-tested devices are actually walking down it. As of 26-28 August 2026, the G98 Type Test Register lists precisely eight compliant plug-in solar microinverters: seven UKSOL models and the Perlight PowerPlug MAX 465. Everything else that's been publicly announced as a "plug-in solar kit" — EcoFlow's plug-in solar kit, Anker's plug-in solar kit, kits from TSUNESS, FoxESS, Segen and Modular Solar, and the Octopus Energy device (which was filed using a FoxESS-based inverter) — is currently marked "Non-compliant" on the register. That word doesn't mean the hardware failed a safety test; it means the testing and paperwork process hasn't finished. But the practical effect is identical: it is not lawful to plug in a device marked "Non-compliant" yet, however good the panel or however trustworthy the brand. We track the register directly, because it changes — see the full rundown in the ENA G98 register explained, and the wider legal mechanics in is plug-in solar legal in the UK?

UKSOL, as a result, is currently the only brand you can lawfully plug in today, and its kits are already on sale.

If you would rather read the legal position as a status table than as prose, the law status panel on 800wsolar.co.uk sets out what is legal today, what still needs an electrician and a G98 notification, and which kits are only "not yet certified" rather than approved.

What a UKSOL plug-in solar kit costs

Argos is first online with UKSOL stock, and confirmed listings as of around 28 August 2026 cover five kits spanning 460W to 1260W of DC panel. All five share the same 800W microinverter, which makes the arithmetic on price-per-watt worth doing before you pick a size — the table below works it out from the listed prices.

Two things jump out. First, the Pro Max 1260W is comfortably the best value per watt of panel — at roughly £0.78/W it's about half the cost-per-watt of the smallest Compact 460W kit, because both kits use broadly the same microinverter cost, and that fixed cost is spread over much more panel on the bigger unit. Second, the 460W Compact is a genuine outlier: at about £849 it's priced above the larger 515W and 890W kits, so unless space genuinely limits you to the smallest footprint, the 515W Compact at £599 is the more sensible entry point.

Note that UKSOL doesn't sell through Amazon directly, so the Amazon links above are tagged searches rather than a manufacturer storefront listing — worth knowing so you're not surprised when the result isn't a single dedicated product page. Ground-mount-only versions of the smaller kits (skipping the wall or balcony bracket hardware) are cheaper again direct from uksol.uk, from about £699. For a size-by-size breakdown of which kit suits which garden, balcony or wall, see our UKSOL kits compared guide.

Retailer prices on these kits move, and there is no manufacturer RRP page that tracks them. The independent ledger at 800wsolar.co.uk records the current list price, panel wattage and modelled payback for every certified kit side by side, checked manually rather than pulled from an affiliate feed.

Realistic savings and payback

The government's own figure, from the 26 August 2026 GOV.UK news release announcing the legalisation, is up to roughly £110 a year, covering up to about 20% of an average home's electricity use. Independent UK reporting — BBC News among others — puts realistic savings in a £70-£110 a year range depending on panel size, roof or wall orientation, and how much of your usage happens to fall during daylight hours. Treat that as a genuine range, not a guaranteed number: a south-facing, unshaded 1260W kit in a household that runs the washing machine and dishwasher at lunchtime will land near the top; a north-east-facing 460W kit in a house that's empty all day will land nearer the bottom, or below it.

Running the £70-£110/year range against each kit's Argos price gives a rough payback window:

Two honest caveats on that table. It applies the same UK-wide £70-£110 savings range to every kit for simplicity, but a bigger panel genuinely tends to generate more usable energy across a full day — even though every kit's export still clips at 800W AC — because a larger DC array reaches a useful output earlier in the morning and holds it later into the afternoon. In practice, the smaller Compact kits are more likely to land near the £70/year end of the range, and the Pro Max and Pro Plus more likely to land nearer £110, which narrows the real-world payback gap between kits rather than eliminating it. The 515W Compact still looks like the quickest single payback on paper, but the Pro Max's much lower price-per-watt makes it the better buy if your wall or roof space can actually take the larger panel. For the full underlying maths and how it compares with a fully MCS-certified rooftop system, read plug-in solar running costs and savings and plug-in solar vs rooftop solar.

One practical tip that has nothing to do with the panel itself: plug the appliances you most want to run "for free" — a fridge, a laptop charger, a fish tank pump — into an energy-monitoring smart plug · Check on eBay so you can actually see, in watts and pence, how much of the panel's output you're using in real time rather than exporting to nowhere. Our best smart plugs guide covers models with that live wattage read-out.

Where to buy today vs what's "coming soon"

Right now, Argos is the only major confirmed retailer with live UKSOL stock, covering all five kits above. You can check price at Argos directly for current availability. UKSOL also sells ground-mount versions of its smaller kits directly through uksol.uk from about £699.

Currys, B&Q, Screwfix, Wickes, Amazon (as a proper retail listing rather than a tagged search), British Gas and Lidl have all been reported as bringing plug-in solar kits to market — but as of 28 August 2026 none of that is confirmed live. Treat "coming soon" reports from those retailers as exactly that until you see a real product page and price.

Safety, registration and DNO notification — the must-dos

The relaxed rule still comes with obligations, and skipping them isn't just a paperwork risk — it's a safety one too.

• Register the device. Every plug-in solar unit must be registered at myplugin.solar.
• Notify your DNO. You must submit a G98 notification to your local Distribution Network Operator within 28 days of connecting. This is a short online form, not an approval process — you don't wait for permission, but you do have to tell them it's there.
• One device per household under the initial rules — you can't stack two plug-in kits on separate sockets to get around the 800W cap.
• Check for anti-islanding protection. A compliant kit cuts export instantly if mains power drops, so the plug pins never stay live during a power cut — this is exactly what the G98 Type Test Register is certifying.
• Use a socket protected by an RCD or RCBO in your consumer unit, and check this before you buy rather than after.
• Never use an extension lead between the inverter and the wall socket — plug directly into the wall.

None of this requires an electrician's visit by law, but if you're at all unsure which socket in your home is RCD-protected, it's worth a five-minute check with a qualified electrician or your consumer unit's own labelling before you commit — more detail in do plug-in solar panels need an electrician?

Who shouldn't buy one yet

Plug-in solar is a genuinely new category, and it isn't the right fit for everyone at this exact moment:

• Renters and leaseholders without permission. You need your landlord or freeholder's sign-off before fitting anything to a wall, balcony rail or roof — even a lightweight plug-in bracket. Homeowners in England generally have Permitted Development rights for a simple wall or roof mount, but listed buildings, conservation areas and some flats can differ, so check with the freeholder or local planning office when in doubt. Full detail in plug-in solar for renters and flats.
• Anyone eyeing a brand that's still "Non-compliant" on the register. EcoFlow's plug-in solar kit, Anker's plug-in solar kit, and kits from TSUNESS, FoxESS, Octopus Energy and others may well be fine hardware, but it is not lawful to plug them in until their specific listing flips to "Compliant." Buying now and waiting to plug in later is a legal grey area not worth entering.
• Anyone who actually wants battery storage. This interim rule is explicitly about live-generation export only — a plug-in kit cannot import or store electricity, so if your goal is running the house off stored solar power overnight, you need a different, MCS-certified system rather than a plug-in kit. See plug-in solar vs rooftop solar for how the two categories diverge.
