More than a thousand homes in Richmond have been without gas for five days after a water main burst.
The leak got into gas pipes which meant supplies had to be cut off in the TW9 area.
Distribution company Cadent says it needs to remove all the water before supplies can be reconnected.
Among those affected is celebrity chef Joe Wicks who had to boil a saucepan of water to have a wash.

People living in the affected area have been told not to try to switch their own supplies back on but instead wait for a engineer - many of whom have been brought in from across London.
Restaurant owner Eddie Shing had to turn customers away on what was meant to be a busy weekend celebrating Chinese New Year.
