I started a Nest pension a few years ago. Primarily as an adjunct to an old work defined benefit scheme and a longer running ongoing personal pension through my bank. Mainly putting eggs in other baskets for peace of mind.
I've always found getting the performance information difficult to impossible in my old and new schemes. Even when you do track down a webpage that purportedly tells you what you need to know, you often have limited ability to understand the info, feel like you are comparing apples and oranges and then can't find the same info when you look again some time later.
Just now I've checked the link from upthread, noticed the amazing performance of the SHARIA fund and wondered how do I harness some of that? Then spent 5 minutes going round in circles on the Nest website trying to look at how I could change my fund if I wanted to, and drew a blank!
So to diversify further I then started up another pension with Vanguard as I had heard and read good things about them. Perhaps I have fingers in too many pies now.
Neither my Nest or Vanguard pensions will catch up to my earlier pensions but at least there is some transparency even if I don't fully understand all the graphs, tables, returns, percentages etc
I'm also getting my kids involved early. Hopefully giving them the benefit of what little knowledge I have gleaned.
