Vehicles not meeting the specified emissions standards of the LEZ will still be allowed to drive in London, but they will be required to pay a daily charge of £100 - £200. This means retrofitting would start to become economical at 15 - 30 journeys inside the LEZ.
Operators who do not pay the daily charge and whose vehicles are identified as not meeting the emission standards, will incur a penalty charge. The penalty charge will be £1000 (reducing to £500 if paid within 15 days).
Data held by the Driver and Vehicle Licensing Agency (DVLA) and other agencies will be used to identify the emissions standards of vehicles: The date of first registration can be used to determine a vehicle's emission standard in the majority of cases.
A Low Emission Certificate (LEC) or Reduced Pollution Certification (RPC) scheme will be used to identify vehicles with approved particulate abatement equipment. Vehicles fitted with an Eminox CRT® or FBC system will qualify for LEC or RPC certification.
