Hundreds of homes in east London have been left without gas, after a water main burst on Tuesday.
Elderly residents are being offered electric heaters and cookers
People living in roads around Dagnam Park Drive in Harold Hill have been offered electric heaters and cookers as temperatures plunge.
A drop-in advice centre opened at the leisure centre on Gooshays Drive on Wednesday to keep residents informed.
Supplier National Grid said it had repaired the pipe and hoped to restore some supplies by Wednesday night.
Resources drafted in
Gas supplies in the Harold Hill area of Romford were affected on Tuesday afternoon when a burst water main caused water to enter the gas supply system.
Brian McNamee of National Grid Transco said they had brought in resources from across the country in order to get supplies back on as soon as possible.
"We have been able to repair the gas main and also remove all the water from the system.
"We are doing all that we can to get the supplies back on and we believe we are going to get a significant number back on this evening," he said.
Among those left without gas is retired civil servant Trevor Lowe, 73, who said he had been told it could be off for up to three days.
He said there was an articulated lorry full of temporary heaters and cookers for the area's many elderly residents.
He was pleased with his heater - but said he would not be going out to do his usual voluntary work, as he had not been able to have a shower.
"I will have to boil up some kettles and bring a bucket into the living room and do the best I can," he said.
A spokesman for Havering Council said they were providing support and community welfare.
