Overview
- The UK government expects to change rules this summer so small plug-in solar kits can be sold legally, with a statutory instrument expected to be signed after DESNZ publishes its consultation response.
- DESNZ commissioned an independent electrical safety study that found the devices can be used on domestic wiring if minimum product standards and consumer guidance are applied.
- Manufacturers and retailers say they are ready to supply units and several chains have expressed interest but sales will depend on the formal legal change and interim product specifications.
- Technical safeguards and new certifications such as UL 3700 are being adopted to prevent socket overloads and stop power being fed back into distribution lines, addressing utility and engineering worries.
- The move follows wide uptake in Europe, especially Germany, and growing U.S. state action where more than 30 states have pursued laws to simplify plug-in solar access, while home battery growth could shape how these kits interact with local grids.
