It is the second year in a row that Gatehouse has won the award.
The accolade reflects the bank’s activity in the build to rent (BTR) market, along with its home finance products.
Charles Haresnape, CEO of Gatehouse, said: “This is excellent recognition for all the hard work and innovation the bank’s team has put in over recent years.
“I’m delighted that their efforts have been recognised, especially at an international awards level.
“During a year of unprecedented disruption, we have continued to carve out a strong reputation for delivery and funding across the property sphere.
“The bank’s growth, not least in underserved markets, shows no signs of slowing.”
