A lot can happen. The age for drawing a state pension will rise into the 70s for OP, same for me and I've no intention of working past 60. Going travelling.
The state pension is also peanuts, not something to aspire to live off. Forget decent holidays.
In addition, there will have to be a decrease (and there will be) in benefits spent as its now more than the nhs annual budget. But again the amounts will (and should) come down - benefits should be capped at less than minimum wage to encourage earning unless you're health prevents you from doing so.
But that's by the by, if you want a reasonable retirement you need to plan ahead and pay for it yourself, take some responsibility, and a pension is the best way to do it. It almost becomes addictive logging on to check how much it's grown.
Whilst OPs pot is small, it's not too late. Regular contributions for 20-25yrs will go a long way, particularly if her company match it, and OP will end up in a good position.
Pensions are also exempt from inheritance tax so a great gift to leave if you haven't used it all. It's also very tax efficient and benefits from compound growth which provides a lot of additional free money. And the you take 25% tax free. Shove that in ISAs and you get more interest.
Astounds me that people are not more financially literate. Invest for your future. Good for you OP that you are focused on this now. Put in as much as you can, your future self will thank you.
