Home seller's packs could disrupt the property market with no consumer benefit, according to the Intermediary Mortgage Lenders' Association.
It accuses the Department of the Environment, Transport and the Regions of forcing through legislation for the packs despite industry scepticism.
It wants Chancellor Gordon Brown to investigate and override the DETR over the packs, which it says could suffocate the housing market due to the cost and lengthy process.
The packs will cost up to £163.700 when they become mandatory in January 2003, which could reduce the number of potential sellers.
Imla chairman John Heron says: “Gordon Brown should do more to look at the significant market disruption seller's packs could cause, as this is a market-wide change which has little or no consumer benefit.”
