Homeowner Chris Walsh said all the residents are concerned
A leak of a potentially fatal carbon monoxide left residents of a new housing development in Dorset with no gas supplies.
The supply to the 340-home Harbour Reach development in Poole cut off last Saturday.
The Health and Safety Executive (HSE) took the decision just days before the worst snowfalls in 18 years hit the UK.
Developer Taylor Wimpey apologised and is working to resolve the situation.
Chris Walsh, who moved into his three-bedroom townhouse just over a year ago, said: "It's not been good with the weather the way it is.
"They started by just turning off every boiler on the development, that was Friday.
Every boiler on the development has been turned off
"On Saturday they came round saying they have got to disconnect the whole supply.
"All the residents are concerned. We've been told there are serious problems with the boiler flues and levels of carbon monoxide, it's a silent killer."
Mr Walsh said he and other residents have been issued with two electric radiators each.
"When you buy a new property you get a [gas] certificate that the property has been tested and complies. How can that be allowed to have happened?", he asked.
In a statement, the HSE confirmed the gas supply had been cut off.
"HSE is working closely with all the relevant parties to ensure that what needs to be done is done during the course of the ongoing investigation in order to maintain the safety of all those concerned," it said.
Raglan Housing Association, which also owns properties at the mixed development along with Swaythling Housing Association, said the problem was detected by a carbon monoxide detector fitted in all its homes.
The association has been providing microwave cookers and said residents will receive compensation payments.
A spokesperson for Taylor Wimpey, which owns the site's developer Bryant, said investigation work was continuing.
"We have updated residents and owners on the current situation today and wish to apologise for the ongoing inconvenience," they added in a statement.
