All permanent traffic lights are managed by Transport for London (TFL) and any faults should be reported directly to them online.
Temporary traffic lights
Temporary traffic lights are sometimes used to manage traffic for the duration of roadworks, often works carried out on behalf of a utility company.
Disruptions can occur, though council officers co-ordinate with whoever is doing the works to keep it to a minimum.
Visit the One.network website to check if there are temporary lights on your road.
How to report
If there is an active emergency on the road and if life is in danger, phone 999 for the emergency services.
To report a faulty temporary traffic light please call 020 8937 5600 and select option 3 (Monday to Friday 9am to 5pm).
Before you start
We will ask you for:
- the location of the incident you are calling about
- use points of reference and road names
