The first retail listings arrived within days of the law change. Ideal Home's round-up on 14 September 2026 reports that Argos lists six UKSOL plug-in bundles, Amazon UK two Modular Solar units, Very five UKSOL bundles, Screwfix a two-panel PowerXpress kit, and City Plumbing a range that includes Hoymiles-based kits, alongside Octopus Energy's own one- and two-panel bundles. Prices quoted in that report run from the low £400s to about £1,000 depending on panel count and mounting; delivery estimates stretch from days to late October. We link to none of them, and prices will move.
The government named B&Q, British Gas, Currys, Lidl, Sainsbury's and Wickes as retailers it had consulted when it announced the change, so more listings are likely through the autumn.
What it means for buyers
Availability is not the same as compliance. Since 27 August 2026 a plug-in microgenerator may be used in Great Britain if it meets the Interim Product Specification instead of the usual British Standard requirements — 800 VA and 3.5 A maximum, up to 2,000 W of panels, no battery storage, a BS 1363 plug, one device per household — and the specification requires manufacturers to register each device on the ENA Type Test Register before placing it on the market. A retailer's "regulation compliant" label is a claim; the register entry for the exact model and microinverter is the proof. Our compliance checklist walks through the check.
Three practical points follow. Buy from a retailer that stands behind the product rather than an anonymous marketplace seller, because returns and support matter for a device you plug into your mains. Confirm the microinverter model on the register before you order, not after. And once the kit is connected, notify your distribution network operator — our G98 guide explains the form and why it is mandatory.
Where this leaves our product pages
Our tracked products and the kits overview still describe every kit as not yet verified against the register, because we have not recorded that check for any model and we do not test kits ourselves. That wording will change model by model as we record register entries with the date checked, and not before.
