With thoughtful product design, and seamless integrations with the retail energy system in the UK, the Windfall Battery is the new archetype for the plug-in revolution.

Plug-in solar panels can be installed in the UK from August 2026. We’ll have to wait a bit longer for plug-in batteries, but hopefully not much longer.

In a changing technology landscape, a €300 home battery from Lidl sounds like a pretty interesting proposition. But we need to dig a little deeper.

The Windfall Battery can save you up to £250 per year. But what does up to mean? The answer is a bit complicated, so we’ll break it down.

After months of work, we're excited to announce that pre-orders are now open for the Windfall Battery.

The UK government has just announced some exciting news that means millions more homes in the UK will be able to benefit from home energy tech and reduce their bills, and their carbon emissions.

What actually is the Windfall Battery? Co-founder Ashley has recorded some short videos that provide answers to this, and other FAQs we have on our homepage.

Statistically speaking, it’s very unlikely that you live in a house with solar panels on your roof. Only around 5% of UK homes do. So why are all home batteries designed for people that do?

We’ve recently installed batteries in real homes for the first time and it’s an exciting step forward.

It's a question we hear regularly: "How is the Windfall Battery different from existing home battery solutions like Tesla Powerwalls, PowerVault, and GivEnergy?"

“Why now?” is a classic question asked of start-ups. Why is this the time to launch this business? Here’s our answer.

The core of our product is a battery system that shifts energy consumption from peak to off-peak. But that functionality alone isn’t enough to make a great product.

We’ve been testing existing batteries that are already on the market and seeing if than can work for us. The short answer is that they almost do.

If you don’t have a roof for solar panels or an electric car on the drive, what can you do to reduce your electricity bills?

Here we are, chatting to people at the Everything Electric Show who came over to find out about cheaper, cleaner energy for flats.

Great to meet so many of you at the Everything Electric Show last week!

Right now we’re looking for places that might want to sell our plugs and maybe you are someone, or know someone, who could help.

We are thrilled to announce that Windfall Energy has been selected to join Bethnal Green Ventures' Tech for Good programme. This marks an exciting milestone in our journey to make energy flexibility accessible to everyone, regardless of property type or ownership status.

Knowing that the carbon intensity of electricity varies, and when the ‘greenest’ times are, is all very well but what can you do with this information?

If you want more impact from your Windfall Plug, a great way to use it is with appliances that can run at night.

When we started our first beta tests with real users, we assumed mobility devices like e-bikes and e-scooters would be our primary use cases. Reality proved different.
