Cut your costs
Current energy bill: £104/month, New bill + Sunsave payment: £74/month, Save £30/month
Big energy bill savings from day one
Solar & Battery and Home Battery packages that cut your costs, maximise your savings and protect you for the long term.
Putting power in your hands
The national grid is creaking. Less than 40% of your bill is made up of the cost of energy you buy. Even if wholesale energy prices go down, bills will keep going up for decades, for reasons you have no control over.
We have the answer. Home energy tech like solar panels and batteries massively cut your costs and reduce your reliance on the grid. We’re here to put that power in your hands.
Save more than you pay
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.

The Solar & Battery GuaranteeWe take care of everything
Product warranties only cover the kit, not the labour or scaffolding to fit it. Batteries and inverters wear out, usually after their warranty has expired. With the Solar & Battery Guarantee, we’ll make sure your system keeps performing for a full 20 years – so you don’t miss out on savings.
We’ll monitor your system around the clock to make sure everything’s working, so we catch problems early, before they stop you saving
Everything's covered, so you’ll never get an unexpected bill
Batteries and inverters wear out. When yours do, we'll replace them – even if they're out of warranty
I did think about getting solar panels before, but because of the upfront cost, it just wasn't possible.

Over this next year, I'll see hundreds of pounds worth of savings.

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

That's why I chose Sunsave. I thought: this is real, proper data, rather than somebody pretty much guessing how much I'll save.
Michael
Crewe, July 2026
I know over the next 20 years, the system will be working as it should and any repairs or anything will be covered.
Samir
Sidcup, October 2024
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.
Tim
Guildford, June 2024
The figures just added up. We were going to make a net saving every month ... it seemed like a no-brainer, really.
Jody
London, November 2024
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.
Richard
Hampshire, April 2024
I got my system three months ago. Since then I have already moved to Octopus and saved £400.
