Teachers Building Society says it will now lend to people with any job.
The lender was founded in 1966 when the National Union of Teachers bought London Scottish Building Society to help education workers buy homes.
A Teachers BS spokeswoman says the lender occasionally accepted non-education applicants before, but that the new announcement marked a distinct policy change.
She adds that the lender’s main focus will still be education professionals and the firm will not rebrand.
A Teachers statement says the move is designed to help the firm grow and strengthen relationships with brokers after it re-entered the intermediary market in 2011.
Teachers chief executive Simon Beresford (pictured) says: “We take an individual approach at Teachers, assessing on a case by case basis, so intermediaries can now benefit from this whether their clients are in the education sector or not.
“Our specialist service for teachers is unchanged.”
