Extra staff have been drafted in to deal with the problems.

UK Power Networks said that supplies have been affected by the severe weather across parts of the East of England and South East electricity network.

The company apologised to customers affected and said it was working to restore supplies.

A spokesperson for UK Power Networks said: 'Power supplies have been affected by the severe weather across parts of the East of England and South East electricity network and we have engineers working to restore supplies as quickly as possible.

'Our electricity networks are built to be reliable but extreme weather can sometimes damage overhead lines. We monitor the weather very closely and have robust plans in place to respond to the high winds, including extra engineers and call takers on duty. 'We urge anyone who sees an overhead line down to call our emergency power cut helpline on 105 or 0800 3163 105.' The UK Power Networks website was displaying an interactive map showing details of all the power cuts but pressure online traffic caused that to crash earlier today.
