You can register with Charge Your Car by filling in the form at this link:
You only need to fill in the sections marked with a red asterisk- you can register before you know your vehicle registration number.
The password must be more than 6 characters, have one capital and one numeral, and no 'special characters', such as a '+'.
You will receive a verification email to your chosen address, which you will need to open, and follow the instructions.
Once this is complete, you can log in to your Charge Your Car portal and use the same details to log in to the Charge Your Car app.
