When you contact us, please provide us with as much information as you can, including what the problem is and the number on the column of the light if there is one.
What you need to know...
If a light is not working because the electricity supply has failed the repair is the responsibility of the electricity supplier UK Power Network (UKPN). UKPN will generally reinstate a supply within 25 working days.
If you report a faulty street light, we will repair it within five working days. Please note that we are not responsible for the lighting on red routes. If the faulty street light is on a red route please report this to Transport for London.
For urgent failures such as a road traffic accident or cables or wires exposed there will be a response within one hour.
