A humanitarian aid charity has been sworn in to help vulnerable residents after a power cut wiped out electricity to almost 400 homes.

The power cut happened in the Grove Green Road area of Leytonstone on Monday morning (August 17).

UK Power Network said it was "forced to isolate power supplies to 378 customers" to safely investigate the problem.

The company has not said when power is expected to be fully restored but did set up over 100 generators to get some power back to households.

A spokesman said: "Due to a fault in the Leytonstone area on Monday morning, we were forced to isolate power supplies to 378 customers to allow our engineers to safely investigate and resolve the problem.

"Once it was clear the repair was going to take some time we rushed over 100 generators to site to get power back to customers while we worked to reconnect them to our network.

"We are currently in the process of transferring customers back from generators to our network and restoring all of them to their normal supply.

"In the meantime we have had our customer champions on site to provide assistance and information to customers, as well British Red Cross volunteers to help any vulnerable customers who may need extra care, and provided hot food for all.

"We understand how frustrating it is to be without power and apologise to any customers for any inconvenience cause. Be assured though that we are doing everything possible get the situation resolved as quickly as possible."

UK Power Network would not say if customers would be compensated.
