Households may receive complimentary plug-in batteries as part of potential government initiatives to reduce energy expenses. These batteries operate similarly to power banks, enabling users to store excess electricity during off-peak times for later use when prices are higher.
Typically, energy costs peak on weekday evenings when power consumption is high. Plug-in batteries can be connected to standard wall sockets to store and discharge energy efficiently. They are available in various sizes, ranging from small units the size of a microwave to larger ones comparable in size to a washing machine, priced around £500.
The Department for Energy Security and Net Zero (DESNZ) is considering a program to bulk-purchase plug-in batteries for low-income households. These batteries were among the options proposed earlier under the Warm Homes Plan by former energy secretary Ed Miliband.
While plug-in batteries are viewed as an attractive solution due to their ease of deployment, their implementation is subject to approval by the Energy Secretary, Miatta Fahnbulleh. Current regulations do not permit plug-in batteries as they require dedicated circuits for devices supplying power to the grid, necessitating safety assessments and regulatory updates.
DESNZ’s current focus is on introducing plug-in solar panels, available from August 27, 2026, with potential savings of £70 to £110 annually for UK households. The government emphasizes efforts to reduce energy bills through initiatives like VAT cuts on electricity and the quick rollout of plug-in solar technology.
Households in England or Wales can access financial support for transitioning to heat pumps or biomass boilers through a government scheme. Additionally, those with low incomes and lower EPC ratings might qualify for grants to enhance home energy efficiency with measures like insulation, heat pumps, and solar panels.
