Not Yet UK-Approved Plug-in Systems
Popular balcony systems from EcoFlow, Anker and Zendure that you cannot legally plug in yourself in Great Britain: each either stores energy, which the plug-in rules exclude, or has no Compliant listing on the ENA register. We track them because people search for them, and because the rules may change after the DESNZ battery study. For kits you can install today, see our register-listed kits.

Checked against the ENA Type Test Register on 28 September 2026. The rules, explained
