I’ve recently switched to Tonik after being with OVO and Toto for our Gas and Electricity provider.
As well as being very competitive, they have a great website and a very efficient customer service team.
Being an avid cashback user on sites such as Quidco and Topcashback, I noticed Tonik was not offering any cashback. However now I have signed up, realise both of us can benefit from a £20 Amazon voucher.
Just use the below link and Tonik will send us both a £20 voucher if you switch.
Note: As of March 2018 Tonik Energy is now on the cashback websites. They are currently paying less than if you signed up on the above link as you can benefit from a £25 bill credit instead. Also, you are paid 3% interest of any credit on your account.
