Some 52,000 home loans were advanced for house purchases, up 7% on July, the Council of Mortgage Lenders (CML) said.
There was also a rise in the amount of remortgaging, the figures showed.
But the CML echoed a separate survey of surveyors claiming that the fears over UK and European economies were knocking confidence in the housing market.

"Talk of a recovery risks sounding rather premature.
Average prices still have some way to go to regain the levels of a year ago," said Peter Maskell, director of the Sussex-based estate agents Brock Taylor.
The DCLG survey showed that prices had fallen by 0.
