The Dorset-based mutual has recorded steady growth over recent years, while it hopes to continue growing over the next decade.
James Bawa, chief executive of Teachers Building Society, said: “We’re delighted with our figures for 2014 as the whole team has been working hard to deliver our plan for growth, alongside a truly personal service for our customers.
“Following the tough years of the credit crunch we set a course for continued strength and we’re very proud to have surpassed last year’s lending with over a month to go till the end of 2014.”
Teachers has widened the availability of its mortgage products to all people in Dorset, Hampshire and Wiltshire in recent years.
Colin Dorman, national account manager of Teachers Building Society, said: “Since re-entering the mortgage intermediary market three years ago we have been working hard to secure bespoke products and create fast, efficient processes for intermediaries.
“Our growing relationship with brokers has undoubtedly contributed to this success.”
