Why Now

The UK is opening up plug-in solar

The government confirmed the plug-in route in its July 2026 response and published the final Interim Product Specification, so the direction is now certain. The enabling law is coming into force on 27 August 2026 and no approved kit yet exists, so the compliant install today is still a CPS-registered electrician with a hardwired connection. Read the full breakdown.

Germany insight

Germany installed millions of these. Britain is next.

Over 1.3 million balcony kits are registered in Germany, and the real figure may be closer to three. We dug into what sold, why it won, and the one law change that flipped the switch for renters.

Plug-In Solar Standards Watch

The government confirmed the plug-in route in its July 2026 response and published the final Interim Product Specification. It is coming into force on 27 August 2026, so the compliant install route remains a CPS-registered electrician with a hardwired connection, from around £250.

How It Works

Three steps to your own electricity

The compliant route in the UK is a CPS-registered electrician with a hardwired connection. Typical install time is around two hours and costs from £250.

Buy a kit

Order an EcoFlow STREAM kit online. A complete 800W system includes two panels, a microinverter, and mounting hardware - from £499. Compare the best plug-and-play options.

Mount and connect

Attach panels to your balcony railing, garden fence, or south-facing wall. A CPS-registered electrician then hardwires the system into your consumer unit, the compliant UK route today.

Generate and save

Your system feeds electricity into your home, offsetting what you'd draw from the grid. Watch your bill drop. Understand balcony solar as part of energy resilience.

Common Questions

Quick answers

Not yet. The government confirmed it will proceed in its July 2026 response and published the final Interim Product Specification, but the enabling Statutory Instrument (amending the Plugs and Sockets Regulations 1994 and the ESQCR 2002) is coming into force on 27 August 2026 and no approved kit yet exists. So the compliant route in 2026 remains a CPS-registered electrician with a hardwired connection.
Yes. Under the Renters' Rights Act 2025, landlords cannot unreasonably refuse a portable system with no structural impact. Take it with you when you move.
An 800W panels-only kit like the EcoFlow STREAM starts at £499. Add a 1.92 kWh battery with the Stream Pro from £979. All kits include panels, microinverter, and mounting hardware.
The best defence is layered: cut baseline demand with LEDs, shift appliances to off-peak or solar hours, and generate your own with a balcony kit (self-generated units are immune to price cap rises). Most households get the best return from those first three layers. Read the full strategy →
