Bradford & Bingley plc was a British bank with headquarters in the West Yorkshire town of Bingley. The bank was formed in December 2000 by demutualisation of the Bradford & Bingley Building Society following a vote of the building society's members, who swapped their nominal share of the building society for at least 250 shares of the newly formed bank. In 2008, partly due to the credit crunch, the bank was nationalised and in effect split into two parts; the mortgage book and investment portfolios remained with the now publicly owned Bradford & Bingley plc, and the deposits and branch network (and a licence to use the B&B name for those aspects) was sold to Abbey National, itself owned by the Spanish Santander Group. The branch network was rebranded Santander on 11 January 2010 and the Bradford & Bingley name mainly relates to the nationalised section of the bank. From 2010, the brand has been used under licence for insurance products by BGL Group. History The Merger The Bradford & Bingley Building Society was the product of a merger between the Bradford Equitable Building Society and the Bingley Building Society in 1964. There had been a move towards consolidation in the industry which had as many as 681 societies. In 1963 Bingley made the approach and the merger was effected with the understanding that there would be complete parity of control. Although Bingley had the larger number of branches (29 v 23) it was smaller by assets (£43m v £56m). The Head Office was to be at Bingley; Bradford had the President and Bingley the Vice President; and there were Joint Managing Directors. The new Society ranked number eight in the industry. Sustained Growth The period between the merger and the conversion to a public company in 2000 saw sustained and substantial growth. Financial growth was aided by inflation, particularly in house prices, but the increase in members was from 164,000 in 1964 to 1.85m in 1988. As well as organic development through the opening of new branches there were 24 acquisitions of other building societies between 1967 and 1987. The Hearts of Oak Society in 1982 was of particular benefit as it brought in 28 branches, mainly in the south-east. By 1988 the number of branches had increased from the 52 post-merger to around 250. Despite all this, the Society was still only number eight in the industry –
