A family with an eight-month-old child could become homeless in an ongoing battle with Hillingdon Council.
Kris Conway, 30, of Yeading Lane, Hayes, who lives with his daughter, Morgan, and partner, Christine, says he has been repeatedly misled by the council over how much rent he has to pay.
He says the confusion caused him to be left in arrears, which if unpaid will lead to his family's eviction.
Mr Conway receives housing benefit as he is the sole source of income for the family, working three hours a week as a cleaner at the Co-Op in Uxbridge Road, Hayes.
He said: "I've called the council at least four times in the last few months to check how much I owe as my circumstances changed, and each time they told me I don't owe anything. But now they're saying I could be made homeless and that it's not their problem.
"They've told me I should have been paying £50 a week for the last three months which now means I have to pay the landlord £600 and I just can't afford to pay it.
"They've also said they won't be paying next month's rent until they have reassessed my situation, which could take up to six weeks or longer.
"I don't care about me but I have an eight month old child to worry about."
Neil Stubbings, head of housing at the council, said: "It is Mr Conway's responsibility to ensure his rent is paid, however he has failed to do this and now owes his landlord money. Any action resulting from this will be taken by the landlord.
"It is also his responsibility to let us know about changes in his circumstances.
"When we have been informed about these changes we have worked with Mr Conway and reassessed his benefits as soon as possible, most recently in under one day.
"We are continuing to support Mr Conway and have referred him to our housing advice team."
