The number of mortgage approvals in the UK fell to a five-month low in February, according to new figures from the Bank of England.
There were 51,653 loan approvals to a tune of £7.7 billion in February, compared to 54,187 in January and down again from the average of 52,395 over the previous six months.
Brian Murphy, head of lending at the Mortgage Advice Bureau, said: "The fact that overall mortgage approvals slipped again - with house purchase approvals down for the second successive month - shows how important it is to encourage more activity in this area.
"It is vital the Treasury and Bank of England keep homebuyers firmly in mind if they extend or adjust the Funding for Lending Scheme, rather than switching their attention to small businesses."
He added the government's Help to Buy scheme should encourage the market but warned the January 2014 launch of the mortgage guarantee scheme could see the market stagnate until then as buyers wait.
Peter Williams, executive director of the Intermediary Mortgage Lenders Association, said: "If it is implemented effectively, the new Help To Buy mortgage guarantee will encourage higher loan to value (LTV) lending, but there are eight long months before this comes into play and there are lots of operational details still to settle.
"Expanding the First Buy equity loan scheme to all new homebuyers in the meantime will certainly help to boost the number of mortgage approvals.
"But with new build homes in short supply, we must hope that it also encourages house builders to increase output to meet the extra demand."
