Dozens of properties are without electricity after a power cut in Seaham.
Northern Powergrid is working to restore supplies to around 100 properties in the SR7 and SR8 post code area.
The cut was first reported at 3pm and the firm says it has already restored power to some customers.
The rest are expected to have their services restored by 9pm.
Northern Powergrid says the problem has been caused by an unexpected problem with the electricity cable that serves the area
