Leeds Building Society
Leeds Building Society was founded in the late 19th century, and is now the UK's fifth largest building society.
As a building society, it's owned by its members. This means it doesn't answer to shareholders, so can focus on providing its members with great service instead.
Leeds Building Society offers savings accounts and mortgages, but no current account. They also provide home insurance underwritten by Aviva and life cover provided by Legal & General.
