Anyone have a solid understanding of this? I have two or three little pension pots from previous employers - 2 or 3 years here and there which I'm considering transferring in to my current employer pension (USS). They've offered good transfer values but is there a downside to doing this that I might be missing? Is it better to have several little pension pots that might pay £100-odd a month by retirement or is it better to put everything into my current scheme (which I'm likely to be paying in to for many years)?
