It's time for a new balance of power. Transform how you manage your energy needs with our home battery. It lets you store electricity – either overnight from the grid when prices are low, or from your solar panels – for use at the most expensive times of day. Now it's you who's in charge.
Coming soon
As an energy supplier, we link solar power and home batteries in a way no one else can – passing the benefit back to our members.
Save up to 70% off your electricity bill in the first year when you pair your Tonik Battery with solar panels
Keep powering your home with solar energy even when it’s shining on the other side of the world
Top up your battery with cheap overnight energy to beat peak time pricing and shrink your bills
Purchase a battery at the same time as solar and you'll benefit from 5% VAT – rather than the standard 20%
Battery storage is a game-changer in our ability to produce clean power from renewables
