The cash machine outside the bank is also out of order.
The Brenchley pub has kept its doors open, with dozens of people still inside despite the lack of electric.
Certain appliances still had power while the lights didn't.
Staff have put up signs informing visitors that they are only able to serve limited items on their food menu and the choice of drinks is limited to coffee, tea, certain soft drinks, spirits and beer.
The lights inside have been flickering.
Workmen are dealing with the issue in the street.
All supplies were restored by 12.45pm.
Other businesses down the street were unaffected, including Hollywood Nails and Beauty, Sandersons estate agents and Pars Supermarket.
