A proposed cap of 0.75% on pension management fees could be too high, and might encourage some funds which currently charge lower fees to "push their charges up", a consumer watchdog has warned.
The government is consulting on a number of options for auto-enrolment schemes as part of what it has described as a "full frontal assault on pension charges".
But Richard Lloyd, chief executive of Which?, told BBC Breakfast that the detail of any plan would be vital to ensure a good deal for consumers.
