The aim is for HBOS to tap into Experian's analytical capabilities and data resources to help improve HBOS' risk decision making and to create new credit products more quickly.
The move, involving a substantial investment over the next five years, will provide the HBOS Group operations in the UK and Ireland with access to Experian's data and value added services.
As part of the contract, HBOS will roll out a package of Experian products and services to better manage customer acquisition and associated risk, identify and prevent fraud, and help the bank to more accurately match customers and products.
Nick Robinson, head of retail risk at HBOS, said: "We chose a selection of tools from Experian on the basis of their data breadth and quality combined with an impressive record of product innovation."
HBOS' consumer brands include the Bank of Scotland, Halifax, esure and Sheilas' Wheels.
