Cut your costs
Current energy bill: £104/month, New bill + Sunsave payment: £90/month, Save £14/month
Cut your energy bill with our all-in-one home battery packages


Electricity costs the least in the middle of the night, when demand is lower. But most households pay the same rate all day long.
Your home battery automatically fills up on electricity when prices drop, stores it, then uses it to power your home when prices rise again. So you save money by paying the cheapest rate as often as possible.
Until now, you’ve needed thousands in the bank to own home energy tech. With us, you can pay £0 upfront to own your system and save on your energy bill straight away.

That's why I chose Sunsave. I thought: this is real, proper data, rather than somebody pretty much guessing how much I'll save.

I did think about getting solar panels before, but because of the upfront cost, it just wasn't possible.

Without Solar & Battery Plus, we’d have had no chance of switching to solar.

I know over the next 20 years, the system will be working as it should and any repairs or anything will be covered.

The figures just added up. We were going to make a net saving every month ... it seemed like a no-brainer, really.

I’ve already recommended Sunsave to a number of my neighbours who have expressed some interest. Sunsave have just been very, very good, and very helpful.

We’re saving about £400 each year, which is great. My main goal through Solar & Battery Plus was to cancel out my current energy bill, but now the system is actually paying for itself.

I got my system three months ago. Since then I have already moved to Octopus and saved £400.
