2.3M Londoners in flats are missing out on cheaper, cleaner energy.

If you live in a flat you might feel like there’s nothing you can do to make your electricity use greener.

You don’t have a roof for solar panels and you don’t have a garden for a wind turbine.

Electricity is cheaper and greener at night and we make products that help you capture it, no matter who your electricity supplier is.

Our Windfall Battery charges up with cheap, green electricity at night and then puts that electricity back into your flat during the day.

Our Windfall Plug turns on at the optimal times in the middle of the night to charge and power your devices with green energy.

They will help you save money on your electricity bills and reduce your carbon footprint at the same time.

Windfall Energy develops simple-to-use home energy products designed to help urban residents use electricity when it’s cleanest and cheapest.

We’re proud to be backed by Bethnal Green Ventures, Europe’s leading early stage tech for good VC.

We're launching our first product, a smarter smart plug, in early 2025, but you don't have to wait that long to get involved! We're opening for pre-orders soon.
