Two Months of Legal Plug-In Solar: The UK Market in October 2026

It has now been two full months since SI 2026 No. 848 made the "plug-in microgenerator" a legally recognised category in the UK, on 27 August 2026. We've already covered the launch weekend, the first week and the one-month mark. This piece looks at what's changed since then, now that two autumn months of real generation data, retailer stock cycles and compliance scrutiny are behind us.

Sales have settled into a steady rhythm

The initial surge of early adopters — people who had been waiting years for plug-in solar to become legal — has worked through the system. What's replaced it is a steadier, more considered buying pattern. Retailers report that September's rush gave way to an October that looks more like normal appliance retail: comparison shopping, price-tracking, and a noticeable swing towards kits under £600 as colder, shorter days make buyers more price-conscious about payback periods.

B&Q, Currys, Amazon, Screwfix, Wickes and Lidl are all still stocking compliant kits, though shelf space allocation has shifted slightly in favour of the brands that proved reliable through September's demand spikes. Our retailer price comparison from last month still broadly holds, though a few mid-range kits have crept up by £20–£40 as early promotional pricing has expired.

EcoFlow STREAM remains the reference point

Two months in, the EcoFlow STREAM range is still the kit most other manufacturers get compared against, and it's the one we keep recommending to readers who want the fewest headaches: compliant out of the box, straightforward app monitoring, and stock availability that has stayed healthy since the early-September shortages cleared.

What the compliance registry tells us

The ENA's live compliant device registry has kept growing steadily rather than exploding, which is a healthy sign — it suggests manufacturers are going through proper G98 testing rather than rushing uncertified kits to market. We flagged several of the newly ENA-approved kits that landed in October, and it's worth checking that list before buying anything from a less familiar brand: a device not on the registry is not legally sellable as a plug-in microgenerator, whatever the listing claims.

Trading Standards activity has picked up modestly as more non-compliant imports surface on online marketplaces, usually breaching the 800VA/3.5A cap or shipping with a battery wired into the plug circuit, which SI 2026/848 explicitly prohibits. If you're ever unsure whether a listing is legitimate, our guide on how to spot a non-compliant kit is the fastest way to check before you buy.

Generation through a changing season

October has been the first real test of plug-in solar through declining daylight hours, and the data broadly matches what we predicted in our October generation guide: daily output from an 800W kit has fallen from August's highs to something closer to 1.5–2.5 kWh/day on a typical south-facing install, depending on weather and location. That's a meaningful drop, but it's in line with expectations — nobody buying plug-in solar in the UK should be expecting flat year-round output, and the sharper test will come in December and January.

Owners who registered their system with their DNO under G98 early on report the process has stayed simple and fast two months on, with most notifications still being auto-acknowledged within days.

What we'd tell a buyer in late October

If you're only now considering plug-in solar, the picture two months in is reassuring rather than dramatic: prices have stabilised, the EcoFlow STREAM and a handful of other kits have proven themselves through a full season change, and the compliance framework is doing its job of keeping dodgy imports off legitimate retail shelves. Our complete buyer's guide and best kits roundup are both still current starting points, and with winter coming, it's worth reading our winter preparation guide before you install.

Has plug-in solar lived up to expectations after two months?

Broadly, yes. Sales have stabilised, compliant kits have performed close to their rated output in realistic UK conditions, and the DNO notification process has stayed straightforward. The main surprise has been how quickly the market matured from launch-week hype to routine retail.

Is it too late in the year to buy a plug-in solar kit?

No — installation takes under an hour for most kits, and even reduced winter generation offsets some grid consumption. Buying now also means you avoid any spring rush and have the system fully bedded in before next summer's peak generation season.

Are there more compliant devices available now than at launch?

Yes. The ENA registry has added new manufacturers and models steadily since August, including several newly approved kits in October, giving buyers meaningfully more choice than they had in the first weeks after legalisation.
