Many years ago I was employed in a role where I opted out of SERPS for a few years. As far as I am aware I was not opted into a workplace pension at that time and I have done a search on the government’s lost pension finder with no success. The appeal at that time was that I would pay reduced NI contributions, as it was a very low paid role and I wasn’t thinking about my retirement. However, I have recently read that the money that was saved on NI would have been invested somewhere. Does this mean that there would definitely be a scheme somewhere that the difference would have been paid into? Or were some people able to just pay a lower amount of NI with no investment? FWIW I have checked my pension forecast and will be entitled to £241.30 and I cannot improve my forecast any more so perhaps this is nothing to worry about?
