Tesla Cost to charge calculator

Find out how much it will cost to charge your Tesla with the UK’s most ‘EV friendly suppliers’. By using this simple calculator, you can find out the cheapest UK energy provider to charge your Tesla.

Regardless of which energy supplier you decide to sign up with, the process is now very simple, so don’t be afraid to get a better deal! At the worst, you will just be called by your existing supplier, asking you to reconsider (3 missed calls from Bulb for me).

* GoFaster can either be 5 hours at a slightly high rate, or 4 hours at the regular Go rate. You can choose from a set range of those hours when you sign up
** EDF GoElectric is currently only available to existing GoElectric customers – these are the last known prices (March 2024)
