Clerical Medical has warned that DSS plans to increase levies to run four separate pensions bodies could stretch the one per cent stakeholder cap to the limit.
The life office says this year's increase is unavoidable but it remains concerned that significantly increased levies could put strains on the already slim margins for stakeholder.
The increased levy will be used to run the Pensions Schemes Registry, the Pensions Ombudsman and the Pensions Advisory Service and the Occupational Pensions Regulatory Authority.
The proposals were made in late January as part of a DSS draft document for discussion.
The life office fears further hikes when the bodies start to monitor stakeholder pensions after they are launched next year.
It is not arguing against the need for the four bodies but is concerned that if a 50 per cent hike is needed to prepare for stakeholder it could become much more in the next few years stretching the one per cent margin to the limit.
Clerical Medical head of corporate affairs Tony Bloomer says: “It's the same old clash. When will the Government and those providing the infrastructure for stakeholder realise the one per cent margin is already thinly stretched?”
