Sarah Boxhall reports on the new campaign

The campaign will alert people who bought a personal pension between 1988 and 1994 that they might receive information through the post inviting them to put forward their case for review.

The companies which originally sold the pensions should send the customers letters headed R U Owed?.

It is estimated that up to four million people will be contacted and may be eligible for compensation.

The campaign, the second phase of the continuing investigation into the pensions mis-selling scandal, will focus on consumers who were under 35 when they bought a personal pension.

Awareness campaign

The pension mis-selling scandal occurred in the late 1980s and early 1990s when commission-hungry salesmen wrongly advised as many as two million people to opt out of occupational schemes and take out personal pensions.

The pensions review director of the Financial Services Authority, Ron Devlin, said: "Many younger people are still not aware that they have been affected by personal pensions mis-selling and may be eligible for compensation.

The FSA is now focusing on younger people who were mis-sold pensions

"The aim of the review is to give people who could have been at risk of mis-selling the opportunity to have their pension checked. People should look out for the ads and the envelope and take action if they feel they have been mis-sold."

Consumers who feel they were mis-sold a pension, but have not been contacted by March by the firm which sold it to them, should then contact that company.

Pension companies and financial advisers were ordered to investigate and compensate all older customers who have been mis-sold pensions by the end of last year.

In tune with the government's "naming and shaming" policy, the FSA will publish over the next two weeks the names of those companies who have, and have not, compensated all "priority" cases of pension mis-selling.
