The introduction of Home Information Packs could lead to a fall in the number of properties being put up for sale, a pressure group claimed yesterday.
Splinta - Sellers' Pack Law Is Not The Answer - said the introduction of the packs in June next year could have "disastrous consequences" for the property market.
The group, which questioned 721 people currently selling their homes in England and Wales, found that 43 per cent would not have put their property on the market if they had had to compile one of the packs.
A further 18 per cent said they may not have gone ahead with their sale if the packs had been introduced, while only 39 per cent said they would definitely have still put their property on the market.
From June next year anyone wanting to sell their home must first compile an HIP, which will include title deeds, local authority searches and a home condition report.
The packs will cost up to £1,000 to put together.
Nick Salmon, of Splinta, said: "We have been telling the Government time and again that the Home Information Packs will disrupt the property market because the liability for a seller to pay for a pack is a major deterrent.
"This evidence shows over 60 per cent of sellers will not or may not sell at all after HIPs come in.
"The effect will be fewer homes for sale, a lack of consumer choice and rampant house inflation.
"No matter how Government and the HIP providers - who of course stand to make millions of pounds each year from the pack - dress them up, HIPs are an expensive disaster in the making."
The research comes the day after the Conservatives launched an assault on Government plans to introduce the packs, calling for them to be scrapped.
Other figures from the property industry, including Kirstie Allsopp, the presenter of Channel 4's Location, Location, Location , have also warned that their introduction risks destabilising the housing market.
