Only a third of those without a current pension intend to remain in personal accounts when they are introduced in 2012, according to the Scottish Widows 2007 Pensions Index.
More than 20 per cent of respondents are planning to opt out of personal pensions and 43 per cent are still undecided.
The Index also found that if the Government introduced personal accounts today, the average amount people would be prepared to save is £29 per month, far less than the amount of workers’ salaries envisaged by the Government.
Almost a quarter of workers are not saving at all for their retirement and one in three people actively saving do not know what their main source of income will be in retirement.
Scottish Widows head of pensions market development Ian Naismith says: “While confidence seems to be returning slowly to the pensions market, 51 per cent of those who should be preparing for retirement are still not saving adequately.
Despite pensions being front page news for much of the past year, there is still some way to go before the nation is truly on track – when you strip out those people that are relying on final-salary schemes, three-quarters of the UK population is still not on track for a comfortable retirement.”
