This charge is in addition to the Congestion Charge, which costs £15 per day and is in operation every day between the hours of 7am and 10pm, with Christmas Day being the only exception.
That means a London commuter with an affected car could be facing an average annual bill of around £5760 for weekday driving just in Congestion Charge and ULEZ fees.
If you fail to pay the ULEZ charge by the following evening, a penalty notice will be sent to the owner of the vehicle.
