The Congestion Charge is a £15 daily tariff and payment enables motorists to drive around, leave and re-enter the charging zone as many times as required in one day.

There are no barriers or tollbooths; instead drivers are paying to register their Vehicle Registration Number (VRN) on a database.

Cameras read a vehicle’s number plate as it enters, leaves or drives within the charging zone and checks it against the database of those who have paid the charge or those who do not have to pay (because they are exempt or registered for a 100% discount).

Once a VRN has been matched, the photographic images of the vehicle are automatically deleted from the database.

The charge can be paid via Auto Pay which is an automated payment system that has a discounted daily charge rate.

Drivers need to register with Transport for London (TfL) to pay via Auto Pay.
