Keep your cash
Even if you have the savings to pay upfront for your system, your money can keep working for you elsewhere – while your system is working hard for you at home.
Our 3-year term uses the government's Warm Homes Loan Scheme to bring your interest down to 0%, so you don't pay anything extra for taking out the loan.
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.
