Certified Plug-In Solar Kits UK: Live Tracker

Which plug-in solar kits are certified against the UK Plug-in Solar Device Interim Product Specification v2 and legal to connect via a standard socket from 27 August 2026. We check manufacturer, retailer and GOV.UK sources and update this page weekly.

Last updated:

Current status: no kit has completed UK Interim Product Specification v2 certification yet. Several are on sale in the UK, but being on sale is not the same as being certified for standard-socket connection. Certification is expected to begin landing ahead of the 27 August in-force date.

What a kit must meet to qualify

Under SI 2026/848, a “plug-in microgenerator” must satisfy all of the following:

  • Generates electricity only from sunlight (solar)
  • Maximum AC output of 800 watts
  • Connects via a standard plug approved by a notified body
  • Operates in parallel with the distributor's network
  • Batteryless (no importing electricity to store for later use)
  • Complies with the Plug-in Solar Device Interim Product Specification v2 (16 July 2026)

FAQ

Which plug-in solar kits are certified in the UK?

As of 24 July 2026, none have completed certification against the UK Interim Product Specification v2. SI 2026/848 comes into force on 27 August 2026 and manufacturers are certifying now. This page is updated weekly.

Is a kit that's on sale automatically legal to plug in?

No. Being on sale in the UK is not the same as being certified for standard-socket connection. Only a kit certified against the Interim Product Specification v2 is covered by SI 2026/848 from 27 August 2026.

What happens on 27 August 2026?

The PSSR amendment (SI 2026/848) comes into force. From that date a certified kit can legally connect through a standard socket, one per household, with the owner notifying their electricity distributor.
