Be very careful and do some maths before opting for an EV tariff.
Octopus cheapest is 10p during the night and 41p during the day. I currently pay 31p on my standard tariff.
I worked out octopus would be more expensive for me.
If you don’t have solar etc then the EV tariffs only seem to be viable if you can move some of your normal usage into the night. Such as washing machine and dishwasher.
Also how and when you charge to consider. If you can charge away from home cheaper then the benefits of an EV tariff are even less.
But don’t automatically assume an EV tariff is best. Do the maths.
