The snappily titled The Occupational, Personal and Stakeholder Pensions (Miscellaneous Amendments) Regulations 2009 provide (among many other things) for connected employer bulk transfers to be made from a formerly contracted out scheme (such as a closed pension scheme) as opposed to only from a currently contracted-out scheme
without consent from 6 April 2009.
Bit of an arcane point but I wonder how many transfers were made in breach of the old rules – I can think of at least one where the lawyers may have got this wrong. I suspect there are may be others.
Would suggest schemes take legal advice to make sure they tie up any loose ends.
