Mortgage searches rose to 2.15 million in March, according to data from Twenty7Tech, as borrowers reacted to the ongoing economic uncertainty and changes in mortgage rates.
Data from the firm’s Insight Pro platform shows searches increased 19% compared to February and 17% year-on-year, the highest level of activity so far in 2026.
The increase comes amid ongoing volatility in financial markets, including changes in interest rate expectations, energy prices, and broader geopolitical factors affecting swap rates and mortgage pricing.
Remortgaging was a major driver of activity. Residential mortgage searches rose to 907,610 in March, up 32% month-on-month and 37% from a year earlier, as borrowers nearing the end of fixed deals moved to secure new rates.
Purchasing activity also increased despite affordability pressures. Residential purchase searches reached 725,485, up 8% on February and 5% year-on-year, indicating continued demand from buyers.
First-time buyer searches rose 5% month-on-month to 173,752, although they remained slightly below levels seen a year ago.
The buy-to-let sector also saw renewed activity, with searches rising to 343,746, an 18% increase on February and 12% higher than March 2025, as landlords re-evaluated borrowing strategies.
Nathan Reilly, chief client officer at Twenty7Tech, said: “The data highlights how closely borrower behavior is linked to macroeconomic signals.
“The increase in search volume shows that the market is reacting to a mix of improving momentum and ongoing uncertainty.
“Globally, volatility in energy markets and broader geopolitical tensions continue to impact inflation expectations and mortgage pricing, while here in the UK borrowers are still undergoing affordability pressures.”
