Wegener Business Data will work with BT Business on maintenance of the BT Retail Business database, as well as on data cleansing, enhancement and segmentation.
The appointment comes after Wegener completed a year's contract working on cleansing and enhancement data on some 1.7m customer records.
The renewed contract will involve matching the BT Business database against Wegener's own business database, PrimeFile plus, and making the cleaned and enhanced data available for profiling and analysis work.
Mark Chipperfield, senior analyst, BT Retail, said: "Wegener demonstrated a professional and customer-focused approach to our initial business problem. The data enhancement contract reflected their strong position in the business information marketplace and their commitment to excellent service."
