However the pick-up came after a lull in lending for home loans at the start of the year, the Council of Mortgage Lenders (CML) figures show.
There was a 2% drop in gross mortgage lending compared with March 2010, the CML said.
A trend of remortgaging in recent months has continued, it added.
Signs of recovery? Gross mortgage lending reached an estimated £11.
3bn in March, the CML said.
However, the big month-on-month rise was the result of particularly low lending of £9.
3bn in February.
A three-month on three-month comparison shows that gross lending for the first quarter of 2011 was £30.
1bn, an 11% decline from the fourth quarter of 2010 and a 1% increase on the first three months of 2010.
"The housing market has emerged hesitantly from hibernation.
Household finances are under a lot of pressure, and as a result demand for house purchase loans fell in the first three months of 2011," said CML chief economist Bob Pannell.
He said that lenders expected mortgages to become more available in the coming months, and this could help to underpin house-buying activity, although still at low levels.
