The service is based on data exclusively supplied to Equifax by For Sale Sign Analysis, which tracks "for sale" and "sold" signs for the estate agency industry.
People who move house spend a lot of money on financial services, said Graham Arrowsmith, Equifax market development director. Since around half of consumers change their mortgage and insurance providers before they move, financial institutions can use the Pre-Mover service to retain and acquire customers.
One building society identified 66% more of its customers who had their house on the market compared to its normal monitors such as requests for deeds, Arrowsmith said.
Equifax can also identify the approximately 10% of people who put their house on the market but don't move by matching the Pre-Mover file against its Edited Rolling Register, a monthly file of individuals who have amended their entry to the Electoral Roll.
Experian recently launched Absolute Movers, a consumer suppression file that updates goneaways on an individual, rather than a household, basis.
