About the ULEZ in London

The Ultra Low Emission Zone (ULEZ) is part of Transport for London’s (TFL) effort to reduce pollution and improve air quality across the capital. This page gives you an overview of what the ULEZ is, why it exists, and how it might affect your travel in and around London.

Pay Your ULEZ Charge

What is the ULEZ?

The ULEZ is a defined area where vehicles must meet strict emissions standards to avoid a daily charge. It was first introduced in Central London in 2019 and has since expanded to cover all London boroughs within the M25—excluding the M25 itself—as of August 29, 2023.

Why the ULEZ Exists

This initiative aims to clean up London’s air and improve public health. The key goals of the ULEZ include:

• Cutting down on emissions from older, higher-polluting vehicles
• Encouraging drivers to switch to cleaner, low-emission vehicles
• Supporting more sustainable ways to get around—like public transport, cycling, or walking

How the ULEZ Works

The ULEZ is in operation 24 hours a day, every day of the year—including weekends and public holidays. If your vehicle doesn’t meet the required Euro emissions standards, you’ll need to pay a daily charge to drive within the zone.

The expansion of the ULEZ to all boroughs inside the M25 has made a big impact on reducing harmful air pollutants and improving conditions for residents and visitors alike.
