Since the government’s Money and Pensions Service (MaPS) was formed in 2019, it has operated three consumer facing brands: the Money Advice Service, The Pensions Advisory Service and Pension Wise.

This now offers consumers a single source of information and guidance where information can easily be found in one place.
