I did think about getting solar panels before, but because of the upfront cost, it just wasn't possible.
Tony
Bedfordshire, October 2026
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.

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
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
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 got my system three months ago. Since then I have already moved to Octopus and saved £400.
Ajith
Buckinghamshire, October 2023
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.

Protect yourself from rising energy bills
Between 2000 and 2025, electricity prices increased by 6.2% each year on average. No-one can fully predict the future, but these prices are expected to stay high until at least the late 2030s.
With Solar & Battery Plus, your monthly payments will never go up. That means you're protected against inflation from rising energy bills, and your savings should keep growing over time.
And after 20 years, once your payments end, your annual savings will increase dramatically.

Your panels will work all year round

Solar panels work all through the year, even in the UK. All they need is daylight.
Your solar panels generate the most energy in summer, when you’ll sell the most excess electricity to the grid.
Your solar panel output will drop in winter, but won’t stop completely. You’ll just need to top up with grid electricity.
See what you could save
Solar is a powerful way to save money and reduce your carbon footprint, and there’s no reason people should be excluded due to high upfront costs.
