The new Universal Credit benefit could include a mechanism for landlords to chase up rent arrears.
Tenants who fall behind can have 5 percent of their benefits docked under existing laws.
But the government is considering allowing landlords to recoup all arrears from Universal Credit claimants.
Universal Credit will be rolled out across Britain in the autumn. It combines several benefits, including housing benefit, in one payment.
Millions of claimants will end up with less money.
Tenants who claim housing benefit will be expected to manage their budgets themselves, rather than the benefit going straight to landlords.
