The LEZ operates 24 hours a day, every day of the year, including weekends and public and Bank Holidays.
Charging days run from midnight to midnight. So if you were to drive within the LEZ between 23:30 and 01:00 the next day, you'd need to pay for two days.
Vehicles parked in the zone but not driving are not subject to the LEZ requirements for that day.
Remember, the LEZ isn't the same as the central London Congestion Charge zone. The Congestion Charge applies 07:00-18:00 Monday to Friday, excluding public and Bank Holidays. If you drive within the charging zone during these times you will have to pay the Congestion Charge, even if you meet the LEZ emissions standards and have paid the Daily LEZ Charge.
The LEZ covers most of Greater London.
All roads within Greater London, those at Heathrow and parts of the M1 and M4 are included. However, the M25 is not included (even where it passes within the GLA boundary). Look out for signs at the boundary and side of the road to see where it applies.
Enter a street name, postcode or landmark in the box below to view its location in relation to the zone. To confirm if an address is inside or outside the zone, use the postcode checker below the map.
Information in the map may not be accurate. Results provided by the postcode search tool take precedence.
Use our postcode checker to determine if an address falls within the LEZ (results will not show on the map above).
Look out for signs at the boundary and side of the road to see where it applies.
Once you're inside the LEZ, on main roads there are signs to remind you that you're in the zone and that the scheme is enforced by cameras:
On major approaches to the M25, advance warning signs like these indicate the position of the LEZ boundary, allowing you to choose to divert onto the M25:
Closer to the boundary itself, some approaches have additional advance signs to indicate a route you may take to avoid entering the zone:
There are no barriers or toll booths within the LEZ. Instead, cameras will read your number plate as you drive within the LEZ and check it against our database of registered vehicles.
This database is compiled using information from the DVLA, DVANI, the Driver and Vehicle Standards Agency (DVSA - formerly VOSA), generic vehicle weight data typical of the make and model, and drivers and operators who have registered with us.
This tells us automatically whether your vehicle meets the LEZ emissions standards, is exempt, is registered for a discount, or if you've already paid the daily charge.
If you're driving a vehicle registered outside the UK, you'll need to register it with us to let us know that it meets the LEZ emissions standards so we can add your vehicle to our database.
It's important that you do this, because if you drive in the LEZ without registering, even if your vehicle meets the standards, you'll have to pay the daily charge, or may receive a Penalty Charge Notice.
We also need to reduce emissions from non-road mobile machinery (NRMM) to protect and improve Londoners' health. NRMM used on construction sites was responsible for 7% of NOx emissions, 14% for PM2.5 and 8% of PM10 emissions in Greater London in 2013.
To address these NRMM emissions London has introduced a NRMM LEZ using the Mayor's planning powers to impose minimum emissions standards for machinery used on construction sites. More information is on the NRMM London website.
