Mortgage sales rose to £14.1bn in February by 23.6% from the month before.
Equifax Touchstone analysis found residential sales stood at £11.8bn and buy-to-let sales at £2.3bn.
The North and Yorkshire saw the biggest jump in sales (27.9%) from January, with other major rises occurring in Scotland (26.4%) and the Midlands (25.4%).
John Driscoll, director at Equifax Touchstone, said: “Following a volatile end to 2016 the mortgage market saw a vast increase in sales last month in every region across the UK.
“As the UK moves towards triggering Article 50 we will watch with great anticipation to see how the market responds, and whether there will be a noticeable impact on mortgage sales.”
