Plug-in solar became legal across Great Britain
The UK government announced that from 27 August 2026 plug-in solar panels can legally be bought and used across Great Britain. The policy creates a new small-scale route for households that may not be pursuing a conventional roof-mounted solar project. Safety, product and installation requirements still need to be followed for the specific kit and property.
The government describes kits up to 800 W
The announcement says each plug-in solar kit can produce up to 800 W. It also states that such panels could provide up to 20% of an average home’s electricity use. Those are government-provided headline figures and should not be interpreted as a guarantee for every home, orientation or consumption pattern.
Savings are an estimate, not a universal return
The government says households could save up to £110 per year. Actual savings depend on solar exposure, self-consumption, electricity price, equipment cost, shading and household demand. Melnti will treat the figure as a policy announcement estimate rather than a promised financial outcome.
Melnti interpretation
The change creates a distinct consumer-solar category that deserves careful product and safety research. Plug-in systems should not be mixed indiscriminately with conventional permanently wired PV, batteries or backup systems. Melnti’s equipment catalogue will keep exact-model evidence and public-image requirements in place before any future product promotion.
