Lowering Speed Limits

The Mayor and Transport for London (TfL) is committed to the Vision Zero Action Plan. The Action Plan sets out our ambition to eliminate death and serious injury from London’s transport network by 2041. It details our plans to reduce road danger, including proposals to implement safer lower speeds on the roads we operate and manage across London.

What are we doing?

We plan to lower the speed limit by 10mph in selected locations across London.

Works have started to introduce a 20mph speed limit on roads in Camden, Islington, Hackney, Haringey and Tower Hamlets.

In late 2023, we will begin works to selected roads in Greenwich, Lewisham, Lambeth, Southwark, Wandsworth, Merton, Bromley, Ealing and Kensington and Chelsea.

By May 2024, we will complete works in Sutton, Hounslow, Hillingdon, Wandsworth, Merton, Richmond, Waltham Forest and Enfield.

We are seeking your views on the changes before they are introduced. We would also like your comments on your experience of the new lower speed limits once the works are complete, and safer speed limits are in operation.

You can also view our updated maps in the 'Documents' section. Please note, these proposed changes are subject to statutory traffic order consultations.

We are committed to improving transport in London by making it safe and reliable. All of our plans have been designed with this in mind. Please view our Equalities Statement in the 'Documents' section for more information.

Why do we want to lower speeds?

Collision data from around the world is very clear. It shows the faster a vehicle is travelling the more likely a collision will occur because the driver has less time to react, stop or avoid the collision and the more severe an injury resulting from the collision will be.

If you would like to know more background information, please read our phase 1 consultation report that can be found in the Documents section.

What have we done so far?

As of February 2023, we have provided a 20mph speed limit on 110km of the TLRN across London. In March 2020, we introduced a 20mph speed limit on all our roads within the central London Congestion Charging Zone, under phase 1 of the programme.

In the next phase of the lowering speed limits programme, by March 2024, we aim to lower the speed limit on a further 140km of TLRN, including 37 town centre locations to provide safer, more pleasant environments for people to travel within London.

Since 2020, we have reduced speed limits on a further 46km of our roads, under phase 2 of the programme, including those in Westminster, Haringey, Hackney, Enfield, Croydon and Tower Hamlets. Most recently safer speed limits have been introduced on the A205 Upper Richmond Road, Wandsworth and at Gants Hill, Redbridge.
