Residential remortgage searches increased by 11% year on year in August, despite mortgage search activity slowing over the summer, according to Twenty7tec.
The firm's latest Mortgage Market Snapshot recorded 1,556,758 mortgage searches during August, down 13% from July but 1% higher than the same month last year.
Residential searches also fell 13% month on month but remained 3% above August 2025 levels.
Remortgaging recorded the strongest annual growth, with 616,150 residential remortgage searches completed during the month. This was down 12% from July but 11% higher year on year.
The figures come as separate FCA and Bank of England lending data shows remortgaging accounted for 31.2% of gross advances to owner occupiers during the second quarter.
This represented an increase of 3.1 percentage points from the previous quarter and was the highest proportion since Q1 2024.
Twenty7tec's criteria data showed Joint Borrower Sole Proprietor was the most searched area during August, followed by visa applicants and non UK foreign nationals.
Satisfied defaults and maximum age at the end of the mortgage term were also among the most commonly searched criteria, while buy to let recorded the weakest activity in the August data.
Nakita Moss, head of lender at Twenty7tec, said: "August was undoubtedly quieter than July, but the monthly fall isn't the whole story. Overall mortgage searches remained slightly ahead year on year, and residential activity was 3% higher.
"Remortgaging is particularly interesting. Our searches were 11% higher year on year, and the latest lending figures also show the share of advances going towards remortgaging has increased.
"For advisers, this means there is still a significant population of existing borrowers needing to understand what their next mortgage looks like. In a market where rates and products can change quickly, those conversations can be just as important as activity coming through the purchase market."
