Where to buy plug-in solar kits in the UK

The one check that matters

In Great Britain a plug-in solar kit may be used only if that exact model is listed as compliant on the ENA Type Test Register. The same inverter sold in a different bundle can have its own entry, so the brand alone is not enough. Before you pay, find the model code on the listing or the box and check it against every kit the register lists, or ask the seller for the register reference.

Who sells plug-in solar kits

“Not checked by us” means the figure comes from a news report and we could not read the retailer’s own page. Prices move quickly, so treat every figure as a snapshot.

Retailer by retailer

Amazon UK

Ideal Home reported on 14 September 2026 that Amazon UK lists two Modular Solar units, a 340W unit at £465 and a 475W unit at £650. We could not check the listings ourselves. The register lists four Modular Solar models as compliant, 340W and 475W units each in two inverter versions (MODUL/21168/V1/A1, MODUL/21169/V1/A1, MODUL/21440/V1/A1 and MODUL/21443/V1/A3). Buy from the listing sold by the maker or Amazon itself rather than a third-party marketplace seller, and check the model.

Argos

Argos listed six UKSOL kits on 22 September 2026, from £599 for a single 515W panel with a hybrid mount to £999 for a two-panel 890W kit with a ground mount. Five of them match UKSOL models the register lists as compliant by name. The sixth, a 1260W Pro Max bundle at £989, is described by Argos as having a ground mount, while the register entry for the Pro Max is for a hybrid-mount kit (UKSOL/21013/V1/A2). Ask Argos or UKSOL to confirm that the bundle you buy is the registered model.

Argos also lists EcoFlow STREAM products, including a microinverter and cable kit and STREAM Ultra batteries. When we checked the register, it listed no EcoFlow plug-in solar kit as compliant, and the government’s specification excludes plug-in battery systems. If you are considering these, ask for the register reference of the complete kit you would plug in.

City Plumbing

City Plumbing listed seven kits on 22 September 2026, from £336 to £951.60 including VAT: five of its own kits pairing DMEGC panels with a Hoymiles HiFlow microinverter, and two UKSOL kits (a 460W single panel and an 890W two-panel kit, both with ground mounts, which match UKSOL entries on the register). City Plumbing’s own kits are registered under its company name, City Plumbing Supplies Holdings, which had 13 entries marked Compliant when we checked. Match the kit code on the product page to one of them.

Hampshire Generators

Hampshire Generators ranked first on Google UK for “800w plug in solar” when we checked on 7 October 2026, so it is worth being precise about what it sells. Its site lists several plug-in kits built around the EcoFlow STREAM microinverter paired with its own panels — an 800W kit with rigid panels, an 860W pop-up kit, a 400W kit and a 300W pop-up kit. It is a retailer, not a register supplier, and has no entry of its own.

The register’s compliant EcoFlow entry, ECOFL/21128/V1/A3, covers EcoFlow’s own complete STREAM kits — the flat-roof, façade and pitched-roof versions. A microinverter paired with a different supplier’s panels is a different combination from the one the register lists. Ask Hampshire Generators for the register reference of the exact bundle before you order. The page that ranks for the head term is in its /archive/ section and describes a 300W kit, so check you are looking at a current listing.

Homebase

Homebase does not list a plug-in solar kit. Homebuilding & Renovating reported on 19 September 2026 that Homebase was involved in early distribution discussions but had not launched a product. When we looked on 1 October 2026, Homebase’s website was trading normally but showed no solar category, and its own search returned “No Results Found” — for “plug in solar”, for “UKSOL” and also for ordinary terms such as “paint”, so we could not check its range by search and are reporting only what the category pages showed. If Homebase lists a kit, we will add it with the date.

Octopus Energy

Octopus Energy sells one- and two-panel bundles built around JA Solar 460W panels, with wall or ground mounts. It launched them from £450; its website shows prices once you enter a postcode, and on 22 September it said orders placed from 11 September were expected to arrive between the end of October and mid-November. The register lists one Octopus Energy model as compliant, M1-800-E (OCTOQ/21124/V1/A5). See our Octopus news story.

PatioSun

PatioSun sells direct and has six kits on the register, all marked Compliant: PatioSun Lite (PATIO/21264/V1/A1), Lite+ (PATIO/21294/V1), Duo (PATIO/21026/V1/A2), Duo+ (PATIO/21289/V1), Max (PATIO/21261/V1/A1) and Max+ (PATIO/21299/V1).

When we read its shop on 7 October 2026 it listed PatioSun Home, Lite, Max and Duo at £449 to £749. The names on sale line up with the register entries, which is more than can be said for several bigger retailers. Which? also lists PatioSun among the brands currently selling. The shop is served from a Shopify address rather than the main domain; that is normal, but check you are on a PatioSun page before paying.

Screwfix

Screwfix listed one kit on 22 September 2026: a PowerXpress kit with two 460W bifacial panels, an 800W microinverter and brackets, at £669. The register lists one PowerXpress model as compliant, “PowerXpress Plug-in Solar 920W 2 Panels + Mounting Kit — 90012” (POWEZA/21077/V1/A1). Screwfix’s listing does not show that model code, so ask Screwfix or PowerXpress to confirm it is the registered kit.

Thunder Energy

Thunder Energy sells direct and has six Compliant register entries, all under the Thunder Bolt name: 460W (THUNE/21203/V1), 460W Flat Roof (THUNE/21748/V1/A1), 920W (THUNE/21204/V1), 920W Flat Roof (THUNE/21749/V1/A1), Max 530W (THUNE/21750/V1/A1) and Max 530W Flat Roof (THUNE/21751/V1/A1). Four of those six only became Compliant on 7 October — see our note on that change.

Reading its shop on 7 October 2026, two things are worth knowing. It badges the Bolt 460W (£549.99) and Bolt 920W (£749.99) kits “ENA Compliant”, and those names match register entries. It also sells Storm flexible kits — Storm 360W at £499.99 and Storm 710W at £699.99 — which carry no such badge, and we found no register entry under the Storm name at all. Separately, its “Bolt Plus” and “Storm Plus” bundles include a battery, at £1,499.99 to £1,749.99; battery storage is outside the plug-in route entirely, whatever it is bundled with.

So: the Bolt kits map to the register, the Storm kits do not appear on it under that name, and the battery bundles are a different kind of product. Ask for a register reference for anything that is not a plain Bolt kit.

Very

We read Very’s own listings on 1 October 2026. It lists five UKSOL kits, each one naming an APsystems EZ1-M microinverter: the 460W Pro Compact with a ground mount at £679, the 515W Pro Compact with a hybrid mount at £599, the 890W Pro Duo with a ground mount at £999, the 1030W Pro Plus with a hybrid mount at £899 and the 1260W Pro Max with a hybrid mount at £989.

All five match a UKSOL kit the register lists as compliant, by name, wattage and mount type: UKSOL/21002/V1/A2, UKSOL/21008/V1/A4, UKSOL/21003/V1/A2, UKSOL/21012/V1/A3 and UKSOL/21013/V1/A2. Very’s listings do not print the register reference or UKSOL’s own kit codes, so ask Very or UKSOL to confirm the reference for the bundle you buy. Note that Very’s 1260W Pro Max is the hybrid-mount version, which is the one on the register.

Voltacon

Voltacon sells direct and holds one register entry, the Compliant VOLTD/21572/V1/A2, whose model string is simply “HF-800-WB” — a Hoymiles microinverter. Reading its shop on 10 October 2026, it sells that microinverter on its own at £119, and several complete kits: an “800W Plug-In Solar Kit Hoymiles HF-800-WB With 2x JA Solar 465W Panels” at £390, a version with a Hoymiles HMS-800-2WB inverter at £410, another 800W JA Solar kit at £440, and a “VOLTACON Power 800W Plug In Solar Kit With Ground Mount, 2x JA Solar 465W” at £530, which its listing labels “ENA Registered”.

Correction, 10 October 2026. Until today this section said Voltacon held two further entries, both Non-compliant, for a 465W kit and a 930W kit naming JA Solar panels. Those entries (VOLTD/21533/V1/A3 and VOLTD/21738/V1/A3) were on the register when we read it on 7 October and had been removed by 10 October. We have corrected the passage rather than quietly deleting it.

What that leaves is a single Voltacon entry for a microinverter model, and several kits on sale that pair that inverter — or a different one — with panels and mounts. The register lists combinations, so a kit is covered only if the entry describes that combination. “ENA Registered” on a listing may well be referring to the inverter inside; it is not the same statement as a register entry for the bundle. Ask Voltacon which register reference covers the exact kit you are buying, and check it yourself against our register list.

Buying direct from the supplier

Many suppliers on the register also sell from their own websites. Buying direct can mean more choice of mounts and panel sizes, but check delivery dates and returns terms as you would with any retailer. Whoever you buy from, our register list shows every supplier’s compliant models with their references.

Two of the largest suppliers on the register do not appear to sell to the public. Worldwide Solar holds 31 Compliant entries, more than any other supplier, and Perlight holds 18, but on 7 October 2026 we could not reach a UK consumer site for either. Which? makes the same point in general terms about the register: some companies “have products listed as compliant on the type test register but they are not yet available to buy”. A compliant entry means a kit may legally be used, not that anyone will sell you one.

Take care with

• Marketplace sellers. Zurich UK advises extra care when buying through online marketplaces, where products may not meet UK requirements.
• Kits with batteries. The government’s specification excludes plug-in battery systems and plug-in solar devices integrated with battery systems.
• “UK ready” and similar claims. The register listing is the proof, not the packaging.
• European balcony kits. A kit sold legally in Germany is not automatically listed here.

Retailers that say kits are coming

Ideal Home reported on 14 September 2026 that B&Q, British Gas, Currys, Lidl, Sainsbury’s and Wickes are among the retailers the government consulted about bringing plug-in solar to market. The Independent reported on 27 August that OVO plans a plug-in solar offer in the coming months. We will add them when they list kits. On 1 October 2026 neither Lidl nor Homebase listed one; our Lidl status page tracks that one in detail.

How we compiled this

We read Argos’s, City Plumbing’s, Screwfix’s and Octopus Energy’s own websites on 22 September 2026, Very’s, Homebase’s and Lidl’s on 1 October 2026, Thunder Energy’s, PatioSun’s and Hampshire Generators’ on 7 October 2026, and Voltacon’s again on 10 October 2026, and compared each kit with our snapshot of the ENA Type Test Register. Where we could not read a retailer’s page, we say so and quote the news report instead. We earn nothing from any retailer, we include no seller links, and we list retailers alphabetically.

We add a supplier only when the register shows at least one of its kits as Compliant. On 7 October 2026 that ruled nothing out among the suppliers we looked at, but Hampshire Generators appears as a retailer rather than a supplier because it has no register entry of its own, and Worldwide Solar and Perlight are named without a shop because we could not reach one.

When the register contradicts something we have published, we correct the passage and say what changed and when, rather than editing it silently. The Voltacon section carries one such correction.
