Founded in 2000, Uswitch was acquired by EW Scripps for £210m in March 2006. It started life with a focus on the electricity and gas markets and has expanded into personal finance, car insurance and telecoms.
Uswitch recently moved its advertising account to Adam & Eve from Miles Calcraft Briginshaw Duffy, which came up with a gospel choir-themed campaign that ran from the end of 2006.
Scripps said the sale would not affect its US price comparison business Shopzilla.
