The Plug-in Solar Report: 25 October 2026

Another week of progress for the UK plug-in solar market, with four new ENA-approved configurations taking the total to 127 and three more kits reaching retail. City Plumbing has finally listed its long-awaited dual-MPPT kits, Thunder Energy has introduced a new high-power single-panel option, and InstaGen's kits are now available through Amazon UK. We've also taken a closer look at which Voltacon plug-in solar kits have ENA approval. Here's our weekly roundup.

Four new approvals take the UK total to 127

Four more plug-in solar configurations have been added to the ENA's compliant register this week, taking the total from 123 to 127.

As of 25 October 2026, our directory records:

  • 127 ENA-approved configurations, up from 123 last week.
  • 51 kits with verified retail listings, up from 48.
  • 76 compliant kits not yet on sale, or without an identified matching retail listing.

This week's four new approvals are:

We haven't yet identified a matching retail listing for any of these four configurations.

You can find all 127 approved configurations, including those still awaiting retail availability, in our UK plug-in solar kit directory.

Three more kits reach retail, taking the total to 51

Earlier this week, we published an article looking at the milestone of 50 compliant plug-in solar kits reaching UK retail, just eight weeks after the new rules came into force.

That article also looked at some of the first significant price reductions we've seen, including £50 off both Solarfy kits and £20 reductions across five Worldwide Solar products.

Since publishing it on Thursday, another kit has reached retail, taking the total to 51.

The three new retail listings identified this week are:

The two City Plumbing kits are particularly welcome. We've been waiting for the retailer's approved dual-MPPT configurations to reach retail for several weeks, and they're now finally listed.

Both use the Hoymiles HMS-800-2WB HiFlow PRO microinverter, which can manage each solar panel independently. At just £24 more than their single-MPPT equivalents, these could be attractive options for buyers who want more flexibility over panel positioning. Unfortunately, neither kit is showing as in stock yet.

Thunder Energy's new 530W kit is also worth a mention. It uses a large, high-efficiency LONGi bifacial panel and becomes the highest-capacity compliant single-panel kit we've identified for sale so far.

There's more retailer news too. Both the InstaGen ONE 435W and InstaGen ONE 870W kits can now be ordered through Amazon UK, alongside their existing listings at Currys and Maplin.

Voltacon compliance clarification

In last week's report, we highlighted Voltacon's competitively priced 930W mount-free kit. At £399 delivered, it's currently the cheapest compliant two-panel plug-in solar package we've identified, although buyers will need to purchase mounting equipment separately.

However, concerns remain over how Voltacon is presenting the compliance status of some of its other plug-in solar kits.

One example is its 800W kit using the Hoymiles HMS-800-2WB dual-MPPT microinverter. At the time of writing, Voltacon displays approval reference VOLTD/21572/V1/A2 on the product page for this kit, implying that it is ENA-approved when it is not.

Voltacon has just two approved configurations on the ENA Plug-in Solar database:

Neither approval covers the dual-MPPT Hoymiles HMS-800-2WB kit. The ENA has also confirmed directly to us that VOLTD/21572/V1/A2 applies specifically to Voltacon's single-MPPT Hoymiles configuration.

This is potentially misleading for consumers, who may purchase the kit believing it complies with the UK's plug-in solar rules. We've deliberately chosen not to link to the product while it remains unapproved.

If Voltacon obtains the relevant ENA approval, we'll happily add the kit to our compliant product directory. But for now, we'd advise buyers to exercise caution before treating Voltacon kits using the Hoymiles HMS-800-2WB dual-MPPT microinverter as compliant plug-in solar.

Housing associations take different approaches to plug-in solar

We also investigated how housing associations are responding to the new plug-in solar rules this week, with some interesting findings.

We identified 13 housing providers across England, Scotland and Wales that have published guidance since the rules changed in August.

Five have introduced outright bans on plug-in solar installations, while eight are taking a more flexible approach, considering applications subject to permission, safety checks or restrictions on installation locations.

The contrast is particularly striking given that making solar more accessible to renters was one of the government's original aims.

There are legitimate safety and insurance considerations for housing providers, particularly in flats and shared buildings. But our findings raise questions about whether blanket bans are always necessary, or whether individual applications could be assessed on their merits.

Our full article looks at the different policies, the reasons behind them and what they mean for tenants hoping to benefit from plug-in solar.

What to watch next week

There are still several developments we're waiting for as the UK plug-in solar market continues to expand.

Will Zendure finally launch its anticipated UK plug-in solar range? And will EcoFlow begin stocking its approved kits, which have remained unavailable on its UK website?

We're also keeping an eye on Perlight Solar. Despite having 18 ENA-approved configurations, we're still waiting to see its plug-in solar kits appear at major UK retailers.

And with City Plumbing's dual-MPPT HiFlow PRO kits now listed, it'll be interesting to see how quickly they become available to order.

We'll be back next Sunday with another roundup of new approvals, retail launches, pricing and other developments worth knowing about.
