The Workplace Retirement Income Commission (WRIC) will deliver its final report four months early.
Chaired by former Treasury Select Committee (TSC) chair John McFall, the commission was set up in January to investigate the UK savings gap.
The WRIC had been due to present an interim report at the National Association of Pension Funds (NAPF) headquarters today, with its full and final report expected at the NAPF conference in October 2011.
However, the WRIC is actually likely to present its full findings next week.
A NAPF spokesperson said: "The commission feels it has gathered enough evidence to be able to highlight the main areas of concern which the government needs to take forward.
"Consequently the draft of the interim report has been expanded, and will now be published as the commission's final report."
