Save every household meaningful money, by putting power in their hands
Bills are going to keep rising for decades
The national grid is creaking. Less than 40% of your energy bill is made up of the actual cost of energy – the rest goes into maintaining infrastructure, policy costs and a few other complex factors that ultimately you don’t have any control over. And even if wholesale energy prices go down, bills are going to keep rising for decades.

The future is home energy

There is an answer though: decentralised home energy technology like solar panels and home batteries. Solar lets you massively reduce your reliance on the grid, and batteries mean you only buy energy when it’s cheap. You can generate, store and manage the power you use for a lot less, without being reliant on a system that makes you pay to fix problems you didn’t create.
Set up with the right kit, the right tariffs and the right optimisation, this technology can save really meaningful amounts of money.
We remove the barriers from home energy tech
Kit and installation costs are in the thousands, and it usually takes years to see the payback. Lots of people can’t afford that chunky upfront cost, and even those that can struggle to justify the initial outlay.
Pay absolutely nothing upfront and you can save straight away (plus, you own your kit from day one, you don’t lease or rent anything from us).
A lot of installers fit and forget: when something goes wrong, customers are left with no-one to turn to, and end up footing the bill for hidden costs like battery replacements which a lot of installers don’t warn them about in advance.
We’re long-term partners to our customers because buying home energy tech is a long-term decision – with Sunsave, you’re covered for as long as you’re with us.
Getting home energy tech installed often means dealing with a lot of different companies: an installer for the kit, a finance company for the credit, an insurer for protection. It’s convoluted and a hassle to manage.
Everything in one place, with one bill, kit, installation, financing, long-term protection and battery management.

Putting power in your hands
We began with the UK’s first solar subscription. Since then we’ve expanded to offer Solar & Battery and Home Battery packages that save you money, protect you for the long-term and maximise your savings.
Our smart algorithm, Sunsave Sona, optimises customers’ batteries for the best possible savings every day, and helps balance the UK energy grid.
Since 2022, we’ve helped 1,000s of homes save over £1,500,000 on their energy bills. They’ve reduced their reliance on the grid, and protected themselves against rising prices over the long term.
We’re just getting started though. The opportunity in the UK is huge: there are 30 million households that could benefit from home energy tech.
Over time, this is where we want to get to: becoming the home of home energy across the UK, so we can achieve our mission to: save every household meaningful money, by putting power in their hands.

Our history
Our co-founders Alick and Ben met at Oxford University in 2011, through a shared fascination with energy technology. A decade later, they were surprised at how difficult it still was for people to go solar – especially when energy bills in the UK were so high.
The catch-22 was the upfront cost, which was stopping people from accessing the amazing savings that come with home energy tech. Meanwhile, in the US, Germany and Netherlands, household solar was growing fast, driven by smart financing models that took the upfront cost burden away from the customer.
They knew the technology was there, they knew the appetite was there, and they knew there was a more affordable way to help people make the change. Sunsave was born. Now, more than 4 years later, we’re a team of 80 people who’ve helped thousands of households to make big savings on their energy bills.
