The Building Societies Association says there has been a modest slowdown in the mortgage market in September.
Gross mortgage advances amounted to £2,091 million in September compared to £2,167 million in August.
Approvals rose to £2,135 million in September compared to £2,123 million the previous month.
But building societies fared better in the savings market attracting £871 million of savings in September compared to £547 million in August.
BSA director-general Adrian Coles says: "The slow down is very modest and on a seasonally adjusted basis, in particular, the market still appears to be fairly stable."
