Advisers have likened public sector pensions to 'Ponzi' schemes and say reform is long overdue.
An independent commission led by Lord Hutton this week recommended public service workers' contributions should increase in a bid to cut the rising cost of the schemes.
It also suggested cutting the schemes' "inherently unfair" link to final salaries and calculate payouts instead on workers' career average salaries.
Some advisers have long been highly critical of public sector pensions and have branded Hutton's recommendations unavoidable and fair.
William Crowley, an IFA at Castlegate Investments, says: "Unfunded statutory schemes are probably the largest Ponzi scheme in existence."
Meanwhile, Simon Booth, managing director at ForeSight Independent Financial Planning, says reform is urgent due to the "inequality" of the schemes.
"High earners get a much better deal from the schemes because their pensions are based on their final salary, even though the majority of the contributions will have been made at much lower levels," he says.
"Current members are going to be asked to contribute more to their pensions but, as they are unfunded schemes, their current contributions are used to fund today's pensioners.
"It will be interesting to see just how much extra benefit this will actually translate into for those making additional contributions.
"The concern is any future Government will look to make the schemes less attractive again as the funding gap becomes ever greater."
However, Jon Hill, financial planner at Milford & Dormor Solicitors, says public sector pensions still compare favourably with many private sector schemes.
He says the average public sector pension is £7,800 pa, more than three times the yearly income from a private sector pension fund costing £40,000, which would return £2,311 for a man at 60.
Richard Bishop, an IFA at Premier Practice, says even if public service schemes are linked to career earnings, they would still pay more than a private arrangement.
"Transferring to a private sector pension should be considered very carefully as they would be giving up guaranteed benefits at retirement," he says.
Jason Witcombe, director at Evolve Financial Planning, says all pensions need reforms.
"Terms like ‘gold-plated' and ‘pensions apartheid' get bandied about a lot in the private versus public debate, but the truth is within both sectors there is a huge discrepancy been the haves and the have-nots.
"Yes, public sector pensions need to be watered down but we need to vastly improve private sector pension provision so the overall payout average is at a decent level."
