First Verified Plug-In Solar Kits: Who Is Selling What, Ten Days In

On 27 August 2026 it became lawful to sell and use a compliant plug-in solar device in Great Britain. On the day itself the honest line was that the law had changed and the products had not: the ENA Type Test Register, which is the gate every kit has to pass, had only just started returning Compliant records. Ten days on, the picture is different enough to be worth setting out in full.

Pulled from ENA Connect Direct, filtered to device Type = “Plug-in Solar”, on 8 September 2026: 52 devices, 47 assessed Compliant, 5 Non-compliant. The first Compliant record was published on 18 August 2026, nine days before the in-force date. Further waves landed on 27 and 28 August, on 1 and 2 September, and on 3 and 4 September.

Who Cleared the Gate

By manufacturer, from the register. The count is of device records, and each record is one kit as submitted; the same brand can hold both Compliant and Non-compliant entries for different models.

Four things stand out. UKSOL, a British panel brand, was first through and was the only verified range a mainstream retailer stocked. City Plumbing, a trade merchant, now holds the most Compliant records of anyone, eight, after seven of its own kits were verified on 3 September. Perlight, a Chinese manufacturer with a UK arm, has seven kits through, with the four 500VA versions held at Non-compliant; an eighth Compliant record, the FLEX+ 500, was listed on 4 September and has since gone. And InstaGroup's INS-PPG-800, which sat as Non-compliant through August, was assessed Compliant on 27 August after its ninth amendment, which is the clearest demonstration yet that Non-compliant is a staging state and not a verdict.

Who Is Selling, and For How Much

A Compliant listing is not the same as a product on a shelf. We looked for a live consumer listing for every verified kit; these are the ones we found, with the price each retailer showed on the date given.

The mainstream retailer is Argos, with six UKSOL bundles between £599 and £1,199, free delivery and its usual returns. City Plumbing, a trade merchant that sells to anyone, stocks two of the same UKSOL ground-mount kits for less than Argos charges for them. PatioSun sells its Lite, Duo and Max direct at £449, £549 and £599, Great Britain delivery only, with two of the three still marked pre-order when we looked. Thunder Energy sells its two Bolt kits direct at £549.99 and £749.99 with free delivery. And Modular Solar's own site sends buyers to a single Amazon listing that covers its 340W and 475W units.

Perlight, InstaGroup, hdm solar, APsystems, Skyworth, PowerXpress and The Impact Crowd have verified kits and, as far as we can find, no consumer listing yet, and City Plumbing's own eight kits were not on its website when we searched on 7 September. Most of these names sell mainly through the trade, so expect their kits to arrive via merchants and installers rather than a web shop.

The Names That Did Not Clear It

Most readers arrive here searching for EcoFlow or Anker. Neither has a verified kit. EcoFlow's plug-in device, the EF-PS-800, was published on 26 August and is assessed Non-compliant; its STREAM battery systems were never candidates, because the route excludes devices with a battery inside them. Anker's AE1032Z1-20, which we tracked through August as Non-compliant, is no longer returned under the Plug-in Solar Type at all, and nor are the two GoodWe records that were first onto the register in July. Octopus Energy's M1-800-E arrived on 2 September as Non-compliant and had left the register again by 8 September, which matters because Octopus started selling plug-in bundles from £450 on 28 August with no register reference on the listing; we set that out in a separate report.

Hoymiles is the instructive case. Its HF-800-WB and HMS-800-2WB, the microinverters inside a great many European balcony kits, were both published on 3 September as Non-compliant. Yet City Plumbing's own kits, built around both, have been Compliant since 28 August and 3 September. Two Plugsol kits built around the HMS-800-2WB sat at Non-compliant on 4 September and have since dropped off the listing altogether. The register assesses the thing submitted. A kit can be verified when its inverter, submitted bare, is not, and a kit can fail to be verified when the same inverter sits in a verified kit next door. Check the kit's own reference.

The Seven Named Retailers

In June, DESNZ named Amazon, Asda, B&Q, Currys, Lidl, Screwfix, Wickes as the retailers working with it on plug-in solar. On our 8 September 2026 check we found no verified kit on sale at any of the supermarkets or DIY chains. The only one of the seven with a verified kit listed was Amazon, and that is a third-party brand's listing rather than anything Amazon has ranged. The retailer that actually moved was Argos, which was never on the list. We will keep checking; the day one of the DIY chains ranges a verified kit at a supermarket price is the next real news in this market.

What This Means If You Are Buying Now

• Buy by register reference. Match the model code on the listing to the record on the certification tracker or the register itself. Several brands have Compliant and Non-compliant kits under one product name.
• One device per household. The specification allows one per circuit, but G98 still restricts a household to one device unless and until it is amended. Daisy-chain marketing does not change that.
• Notify your network operator. Mandatory, and the kit's QR code points you to it. Our G98 guide covers each operator.
• Not on timber. Timber balconies and cladding are barred by the specification and, separately, by planning law.
• Northern Ireland is not covered by the use permission; see our Northern Ireland guide.
