The Bank's UK mortgage business (previously Bristol & West) has been effectively closed to new business since January 2009 and the run-down of the business subsequently was flagged as part of the group's EU restructuring plan.

The transaction saw a £1.2bn prime tranche of the Bank of Ireland's UK mortgage book sold to a division of the Nationwide Building Society for c.£1.1bn.

Canaccord Genuity was appointed as financial advisor to Bank of Ireland in relation to the UK mortgage business.
