@annakorp NHS Pension here, tied to state pension age is a major concern for me also. Especially if they just go well nearly everyone has a workplace pension so it doesn't matter if the state pension moves back loads, mine at state pension age is already a few years later than friends with a fixed age and mine will only get longer.
I've just started a S&S Lisa this week and hope that it will let me retire closer to 60 if possible. Thanks for posting this, it's something I've been meaning to ask because extra contributions don't really seem worth it, and SIPPs don't really seem to be something we can do.
I went for the "Legal & General International Index Acc", mostly because everyone says get Vanguard Global All Cap and this is almost the same but has lower fees. The 25% Bonus for the first few years I'm putting into the L&G Tech fund (free money and I'm young, I'll take a little more risk), good historic returns (don't reflect future though) and whilst the fees are higher than the Int Index, they're a lot lower than most tech funds. As always do your own research, not financial advice etc. I also have a S&S ISA I do more regular/active investing with, basically a bit of a lockdown hobby if nothing else, but I'll keep it long term, this is more hands on where as my LISA I'll just do a few lump sums a year and not touch inbetween.
