Plug-In Solar Is Still Not Legal to Self-Install: What the Government Consultation Actually Say
Plug-In Solar Is Still Not Legal to Self-Install: What the Government Consultation Actually Says
The government launched a formal consultation on 16 June 2026. We have read all three documents. Here is what they actually say.
On 16 June 2026, the Department for Energy Security and Net Zero published three documents setting out how plug-in solar will become legal in the UK, what products will need to do to qualify, and when consumers can realistically expect to buy a compliant kit. The consultation closes on 30 June. A policy response is expected by 22 July 2026.
The headlines covering this story have focused on the government's ambition. Plug-in solar in shops within months. £110 a year in savings. A German-style rollout for the UK. What the headlines have not covered is what the documents actually say. The interim product specification published alongside the consultation sets out requirements that no product currently on sale in the UK meets. Not one.
This post covers what the consultation documents say, what the interim product specification requires of any compliant kit, why nothing currently on Amazon qualifies, and what you should do right now.

What Actually Happened on 16 June 2026
The government did not legalise plug-in solar on 16 June. It launched a consultation on how to legalise it. That distinction matters because it affects everything from when compliant products can reach the market to when self-installation becomes permitted.
The Department for Energy Security and Net Zero published three documents. The consultation document sets out the proposed legislative route. The interim product specification sets out exactly what a compliant product must do. The analytical annex sets out the economic case, the savings estimates, and the evidence base from Germany.
The legislative route being proposed is this. The government wants to amend the Plugs and Sockets (Safety) Regulations 1994 to allow plug-in solar to connect via a standard UK BS 1363 plug, provided the product meets the interim specification. This is a different route from the BSI product standard that was previously expected. It is intended to be faster.
At the same time, the Electricity Safety, Quality and Continuity Regulations 2002 will need amending separately. The G98 Engineering Recommendation, which governs how microgeneration connects to the low voltage distribution network, also needs updating. All three changes need to happen before a fully compliant product can legally go on sale.
The government's stated intention is to move at pace. The consultation closes 30 June. A policy response is expected by 22 July. After that, legislation needs to pass, manufacturers need to build products to the new UK specification, and those products need to complete ENA type testing and register on the ENA Connect Direct platform before going on sale. The government says products in shops within months. The documents suggest late 2026 is the realistic earliest date.

What the Interim Product Specification Actually Requires
This is the section nobody else is writing about. The interim product specification is a 40-page technical document. Most coverage of the consultation has not mentioned it at all. It is the document that determines whether any product can legally go on sale in the UK. And it is demanding.
Here is what a compliant plug-in solar product must do under the specification published on 16 June 2026.

What Germany Tells Us About the UK Timeline
The government's analytical annex draws heavily on Germany as the evidence base for UK plug-in solar rollout. Germany is the most developed plug-in solar market in Europe. The documents cite an estimated 3 million devices installed by the end of 2024. That figure is used to support the case that the UK market could scale quickly once barriers are removed.
What the annex also shows, if you read it carefully, is that Germany's 3 million devices did not appear overnight. They are the result of a sequence of regulatory changes that took several years to deliver.
The analytical annex is clear that the German evidence is highly informative about the pace and direction of market development while recognising that UK take-up may differ for structural and policy reasons. The differences it identifies are significant. UK planning and consent requirements in some property types are different. The UK housing stock composition is different. Average solar resource in some UK locations is lower. And the regulatory context is entirely different.
Germany's growth in plug-in solar was also concentrated overwhelmingly in residential houses rather than flats. Around 85% of new devices commissioned in 2024 were associated with one and two family houses. In the UK, where a much higher proportion of the population lives in flats and terraced housing with shared ownership structures, that pattern may not replicate.
The government's own figures show that 800W plug-in solar kits are available in Europe for around £400 to £600. The median installation cost for a full small-scale solar system in Great Britain was £1,595 per kilowatt in 2025 and 2026. That price differential is real and it will drive demand. But Germany took three years of sequential regulatory reform to reach 3 million devices. The UK is at the start of that journey, not the end of it.

What to Do Right Now
The consultation is open until 30 June. The policy response lands 22 July. Compliant products are not expected before late 2026. Here is what makes sense to do in the meantime.
