Monitor your system and track your usage

It's yours, on your terms

Own your system from day one. Choose the payment term that suits you. And pay it off (in full or in part) with no penalties – whenever you like.

Reduce your term or your payments

If you overpay, you choose whether it cuts your monthly payments or shortens your term.

Get an extra battery

Something changing at home? Increase your capacity by adding another battery.

Moving house?

Pay off your balance using funds from your home sale. Or, if you’re on our 20-year term, you can transfer your contract. The new owner will need to pass our eligibility check.

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.

Protect yourself from rising prices

Energy prices are going up, and they’re expected to keep rising over the long-term.

Solar panels and home batteries massively cut your bills, as well as reducing your reliance on the grid, and giving you more certainty over future costs.
