Penalties and enforcement

Skip to navigation

If you drive an affected vehicle in the Low Emission Zone (LEZ) and it does not meet the required emissions standards, is not exempt or registered for a 100 per cent discount and you do not pay the daily charge, you may be liable for a Penalty Charge. This will be issued to the registered keeper of the vehicle.

A Penalty Charge Notice (PCN) may also be issued if the daily charge has not been paid by midnight on the next working day after the day of travel, or if an incorrect vehicle registration mark or day of travel was supplied when the charge was paid.

A separate PCN may be issued for each charging day that a vehicle which does not meet the LEZ emissions standards is driven in the zone without payment of the appropriate charge.

Outstanding charges

If a vehicle is found to have three or more outstanding Penalty Charges against it then further enforcement proceedings may be taken. TfL also has the power to clamp and/or remove it.

Warning letters

TfL will issue a warning letter to the registered keeper of a vehicle identified as non-compliant on the first occasion that it is seen in the LEZ.

From the date of issue of the warning letter, registered keepers will have 28 days to take action. This could include, for example, making the vehicle compliant or contacting TfL if the warning letter has been issued in error.

If the same vehicle is driven in the zone within the 28 day period, a Penalty Charge will not be incurred. After the 28 day period has expired, if the vehicle remains non-compliant and is seen in the LEZ again without the daily charge having been paid, the registered keeper of the vehicle may receive a PCN.
