The Low Emission Zone (LEZ) operates to encourage the most polluting heavy diesel vehicles driving in London to become cleaner. The LEZ covers most of Greater London and is in operation 24 hours a day, 365 days of the year. See a map of the LEZ.

Payment services unavailable

We expect to return to normal service by 08:00 on Monday 26 September 2016. Apologies for any inconvenience.

Congestion Charge/Low Emission Zone (LEZ) payments

If you travelled within either zone on Friday 23 September, you have until midnight on Monday 26 September to pay.

Penalty Charge Notice (PCN) payments

We can't process payments against PCNs until our services resume.

After 08:00 on Monday 26 September you can pay a PCN either online or by calling us on 0343 222 3333 (TfL call charges).

The penalty charge will not increase while our services are unavailable, and will not progress to the next stage of enforcement.


When does it operate?

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 LEZ daily charge.

Where does it operate?

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.

How does it operate?

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 and 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.

Vehicles registered outside the UK

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.

Signs

Look out for signs at the boundary and side of the road to see where it applies.

Within the zone LEZ sign

Inside the Zone

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:
