Proposed free batteries for UK homes
The Department for Energy Security and Net Zero (DESNZ) is looking at handing out free plug-in batteries worth around £500 to millions of households. These devices would charge on cheap off-peak power and release it during peak times to trim bills.
A government source called the idea "so easy to deploy", with the focus on supporting families most affected by high energy costs. Previous schemes like the Warm Homes Plan often targeted households earning £35,000 or less, so a similar threshold could apply here.
Current status
This is still just a proposal under review. Applications aren't open and there's no confirmed rollout date. A DESNZ spokesperson said the Energy Secretary is focused on "working to bring bills down for good" and noted the recent cut to VAT on electricity.
How the batteries would work
- Charge automatically overnight or during cheap periods on smart tariffs
- Discharge stored power when grid prices are highest
- Plug straight into a standard socket with no electrician needed
UK wiring rules would need updating first to allow power feedback into homes.
What this could mean for you
Households shifting use to off-peak times might save 30-34% on bills over ten years, with renters potentially cutting up to £250 a year. While we wait for any scheme to launch, you can already compare deals and switch to a smart tariff that rewards off-peak use.
