The government's plans to introduce home information packs have come in for more criticism in the Commons, but were backed by MPs in a key vote.
A motion tabled by the Conservatives called for the regulations to be annulled before they come into force on June 1.
But MPs voted by 306 to 234 against the motion, ensuring the rules will be implemented as planned and barring a successful challenge to them in the courts.
Wednesday's move came a day after the Royal Institution of Chartered Surveyors said it was to launch a judicial review of the proposals.
And shadow housing minister Michael Gove told MPs: "The truth is that these regulations will only add cost and complexity to the housing market when what we need is more supply and economic stability.
"In the interests of keeping the housing market healthy, I ask the House to throw out these botched, bungled and broken-backed regulations."
Housing minister Yvette Cooper said Gove had talked "a huge amount of nonsense and misinformation about what are sensible and practical proposals".
But RICS has said that ministers failed to consult properly on the plans.
There are also fears that not enough inspectors are in place to carry out the required energy checks.
Plans to introduce the home information packs have suffered a series of blows.
The original move to include survey information was abandoned, prompting consumer group Which? to end its support for the reforms.
But HIPs will include title deeds and an energy performance certificate, which is thought likely to cost house sellers £400-£600.
