The bridging lender upped its previous best of £37m recorded in June by 22% after lending more than £80m in the first quarter.
Stephen Wasserman, director of West One Loans, said: “The post-election feel-good factor has well and truly kicked in for the bridging sector.
“There has been a noticeable uptick since the election result as businesses and developers feel more confident about the UK’s economic prospects without the uncertainties that plagued the country at the start of the year.
“We are confident that the bridging sector will enjoy a strong second half of the year and that West One Loans will continue to be a major player and a first port of call for clients seeking bridging loans.”
