The Halifax started in 1853 as the Halifax Permanent Benefit Building and Investment Society at the Old Cock Inn in Halifax, West Yorkshire. The building society was created to allow working-class people in Halifax to invest their money in a local and 'mutual' organisation.
In 1928 it merged with the Halifax Equitable Building Society and changed its name to the Halifax Building Society. In 1973 the Halifax built its headquarters on Trinity Road in Halifax. By the 1990s the Halifax was the largest building society in Britain, now Halifax is a bank the largest is the Nationwide.
In 1995 the Halifax merged with the Leeds Permanent Building Society, this new larger building society then bought out Clerical Medical Find Managers.
In 1997 the Halifax became a bank and registered with the London Stock Exchange.
By 1997 the Halifax was the fifth largest bank in the United Kingdom and had joined the 'big four' to make it a 'big five'.
The Halifax continued to grow and in 1999 the Halifax bought out the Birmingham Midshires Building Society and Comparetheloan. In 1999 the Halifax set up Intelligent Finance', which was a telephone based bank.
In 2001 the Halifax merged with the Bank of Scotland and former Halifax Bank of Scotland (HBOS). Both brands were kept although some Halifax branches in Scotland became 'Bank of Scotland' and Bank of Scotland branches in Ireland became 'Halifax' branches. This was done because the Bank of Scotland was much larger in Scotland than the Halifax, while Halifax was much larger in Ireland than the Bank of Scotland and had spent a lot of money advertising of Irish television.
In January 2009 HBOS was acquired by Lloyds TSB which subsequently became Lloyds Banking Group. The Halifax is now just a brand name used by this group.
