Low Emission Zone: delivering cleaner air in London

The Low Emission Zone (LEZ) helps us improve London’s air quality by deterring the most polluting vehicles from driving in the city.

What is the Low Emission Zone?

For the long-term health of London and Londoners, Greater London is a Low Emission Zone.  This means that the most polluting heavy diesel vehicles must meet a minimum emissions standard to drive in London.  If they do not meet the required standard they must pay a daily charge

Operators of vehicles that do not meet the minimum standards can take action, such as upgrading their vehicle or fit an approved filter onto the exhaust pipe to reduce their emissions and so drive into the capital without having to pay a daily charge.

You can find out more about the LEZ, boundaries, which vehicles are affected and how you can become compliant, including offers from manufacturers on TfL’s LEZ London website (external website).

Which vehicles are affected?

The LEZ currently applies to lorries over 3.5 tonnes and buses and coaches over 5 tonnes with more than eight seats, plus the driver's seat. The Mayor has confirmed that the emission standards for these vehicles will be tightened from 3 January 2012.

The Mayor has also confirmed that, from the same date, the Low Emission Zone will affect larger vans, minibuses, motor caravans and other specialist vehicles. Cars and motorcycles are not affected.

Deals for drivers

The Mayor has secured big discounts off new vans and minibuses for drivers that will be affected by changes to the zone. Major manufacturers have pledged offers to help the owners buy new, cleaner vehicles.
