Experian will create a fully integrated platform for Homeserve, incorporating data, analytics and campaign management.
The database will aim to improve customer acquisition, loyalty and cross-sell campaigns supported by personalised content.
Homeserve, which specialises in 24-hour emergency home repair services, said signing a deal with Experian would allow it to move forward its business capabilities and find new customer segments.
Duncan Painter, managing director of Experian's integrated marketing division, said: "Major brands like Homeserve turn to us to provide them with [these] kind of capabilities, simply because we know how to unlock their data's potential to deliver hard and fast, measurable financial results."
