  • Honest, personalised savings — no inflated promises
Two ways to save

Whether or not you have solar, a battery pays its way.

We focus on battery storage — the piece most homes are missing. Pick the path that sounds like you.

Already have solar?

Add a battery to your solar

Right now your panels export surplus power for pennies, then you buy it back at peak rates after dark. A battery stores your own daytime solar to use in the evening.

“You’re giving your solar away. Keep it.”

No solar? No problem

Charge up on cheap overnight power

Fill the battery on a cheap overnight tariff and run your home from it through the expensive daytime hours. No roof panels needed — and it’s solar-ready for later.

“Buy power cheap at night. Use it all day.”
