Great Britain legalizes plug-in solar panels for households

Great Britain has legalized plug-in solar systems, allowing households to connect solar kits directly to wall sockets rather than requiring conventional hardwired installations. Effective August 27, 2026, these compliant systems use a microinverter to convert DC electricity from panels into AC power. Regulations limit microinverters to 800 VA, while solar panels can have up to 2,000 W of DC capacity.

The UK government suggests these systems could provide up to 20% of an average home’s electricity needs, potentially saving households approximately £110 per year. This technology is intended to increase accessibility for renters, apartment residents, and those without suitable roof space. However, current rules exclude plug-in battery systems; for example, Anker’s Solarbank 4 Pro still requires a registered electrician for installation in the UK because it must connect to a home’s consumer unit.

Users must notify their local electricity distribution network operator following installation to ensure the small generator is recorded on the network. All systems must meet specific electrical standards, including BS 1363, BS 7671, and the G98 connection standard.
