Manifesto
People in big houses with solar panels are reducing their energy bills, sometimes even to zero.
But that costs a lot of money up front. And you need to own a house with a roof!
What if you rent or live in a smaller home or flat? Like half of the homes in the UK.
Bills are going up and it feels like there’s nothing you can do about it.
That’s why we designed the Windfall Battery.
Unlike other systems, it requires no specialist installation or permanent modifications, giving everyone access to cheaper, cleaner energy
Clean Energy Shouldn't Be a Privilege
This isn't just unfair - it's unsustainable. Real climate action requires everyone, not just the privileged few. Windfall Energy levels the playing field.
Our plug-and-play battery brings energy independence to any home, no installation required. We're turning energy storage from a homeowner luxury into a universal right.
Windfall enables renters and people living in flats to benefit from the clean-energy transition by taking control of their electricity usage.
Living in flats in London we were frustrated that our energy bills were going up and there was nothing we could do about it.
There’s plenty of cheap green energy on the grid these days, but not necessarily at the times you need it. So we started Windfall Energy to develop a battery that lets anyone decouple when energy is purchased from when it is used.
We want to help everyone save money on their bills and use more of the clean energy on the grid.
You shouldn’t have to live in a house like this to benefit from the energy transition.
50%
Half of homes in the UK are either rented or are small homes and flats. Existing clean energy technology just doesn’t work for them.
