The lender also saw 9.4% growth in its mortgage book over the 12 months ending in December 2020.

Simon Beresford, chief executive of Teachers Building Society, said: “There has been continued high demand for our mortgages over the last 18 months, resulting in a record breaking full year performance during 2020 followed by first half lending that has surpassed any levels previously seen by the society.

“The majority of our lending has been to teachers but we’ve also seen strong and sustained demand for our complex lending solutions from the intermediary market.

“With no let up in demand we look forward to helping even more borrowers secure new homes during the second half of the year during which we anticipate our performance being equally strong.”
