Labour MP Nick Raynsford led a debate in Westminster Hall on how investment in social housing could be affected by the government's recent Spending Review.
It was announced in the review that new social housing tenants will face higher rents at 80% of the market rate - though current tenants will see no change.
The National Housing Federation, which represents English housing associations, warned that the change could lead to thousands of low income families having to pay up to £9,000 a year more in rent.
It said the average rent for a three-bedroom social home is £85 a week, but that under the plans that could triple to £250 a week.
Deputy Prime Minister Nick Clegg has said the changes are fair and it was not fair that people who went out to work got less help with accommodation than those who did not.
Responding to the debate, Local Government Minister Andrew Stunnell accused the previous Labour government of failing to build enough social rented accommodation.
However Mr Raynsford pointed out that Labour had refurbished "millions" of homes under the Decent Homes programme.
