Charge up on cheap energy

Image explainer of cheap energy at night, higher costs during the day

Electricity costs the least in the middle of the night, when demand is lower. But most households pay the same rate all day long.

Your home battery automatically fills up on electricity when prices drop, stores it, then uses it to power your home when prices rise again. So you save money by paying the cheapest rate as often as possible.

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.
