Power your home with green energy from Tonik

Together with Mitsui & Co, Tonik is on a mission to help UK homes become more switched on with their energy use. The first step? Switching to 100% renewable electricity and gas which is 10% green and 90% carbon offset. Great news... it only takes two minutes to switch.
