20mph speed limits and zones

There is currently great interest across the country in introducing 20mph speed limits and it is a subject that is often raised by residents in this borough.

Our approach to 20mph speed limits

This Council is committed to delivering a reduction in the speed limit to 20mph borough-wide.

Residents have said they want their streets to be safer, to reduce the risk of accidents and make roads more accessible for cyclists and pedestrians.

We are proposing to reduce the speed limit on all roads in the borough, excluding the A316 and A205 (which are under Transport for London red-route control). This will replace the existing policy under which 20mph zones are implemented on a zone by zone basis.

At this stage there are no proposals for further traffic calming measures, such as speed cameras or speed humps, and in updating signage the Council will take the opportunity to review and rationalise existing signage.

Key benefits

  • Reduce vehicle speeds on our roads, particularly on those roads which have the highest rate of non-compliance
  • Lead to an overall improvement in the liveability of neighbourhoods
  • Create a more consistent landscape of 20mph across London in line with neighbouring boroughs
  • Reduce the need for physical traffic calming measures
  • To aid the Council’s wider aim to improve air quality


The present consultation and traffic surveys are being funded from existing Council budgets. If the scheme is taken forward to delivery, further funding will be sought from both internal budgets and third-party funding sources such as a Transport for London grant. There will be no extra charges passed onto residents to pay for this.

Presentations and communications

Have your say

We want your views on the Council’s proposals to reduce the speed limit on all roads (except the A316 and A205) to 20mph. Working with residents to deliver 20mph speed limits was a key manifesto commitment of the new administration. By Saturday 29 September, all residents will have received consultation material through their letterbox. This sets out our proposals in more detail including the key evidence we have taken into consideration. There is also a frequently asked questions section.

There will be a series of Community Conversation engagement events throughout October, November and December which will include the opportunity to discuss the proposals. View upcoming dates.

If you would like to submit any views or comments about the proposed 20mph limit, please complete our survey form by Friday 21 December 2018. There are also a limited number of paper copies in local libraries, at the Civic Centre and at the Community Conversation events.

Next steps

All survey responses will be fed into a report that will be sent to Cabinet in 2019. Outcomes will be published on this page.
