Based in Birmingham, Tonik counts its customers as part of its ‘positive energy club’ and gives them information on their energy usage and how to save.
Besides gas and electricity, Tonik sells solar pv panels, chargers for electric vehicles and heating insurance from HomeServe. It plans to sell home batteries later in 2019.

Customers will pay £144 extra per year and the tariff will cost £1,192 per year for a medium energy user. It’s still less than the maximum permitted by the cap though, which many other suppliers plan to charge.
