I would still like to know how Paigntonian found out that he could claim his pension contributions back.
If he were to take this option, the big winner would be the DWP who would get their £1,800 pension contribution back (either from their own scheme, or from the third party pension provider).
While the DWP is not required to advise Paigntonian of all his pension options available from the scheme, and they certainly cannot give financial advice in relation to the pension – but to make an offer of the worst option available to persons who have paid into the DWP pension scheme is clearly not in the interest of their staff.
