Name changed because I am going to get roasted.
Financial independence for women is vital. The only person who looks after you is you. The importance of being financially savvy as a women gives you options and freedom.
I would say £100k at 42 is not enough. The good thing is you have time to focus on this (if other things don't get in the way). It is tough but it needs to be a priority (fucking easy for me to say, I know).
I think at 42 I had about £350k in my pension pot. At 58 it is nearly £1M. To be fair a lot of the growth has been in the latter years and I am still paying in significant amounts. It is a tax free saving vehicle and I have utilised and will utilize again the 25% tax free facility to take money out - my plan has always been to utilize this to reduce mortgage.
I am not quite ready to stop work and still have a mortgage but have other assets that would pay this off.
But to be honest I would probably sell and down size at some point in the future. I haven't always made the right financial choices but have ploughed on through the difficulties. I have had to sell a previous home to pay debts and have gone through a husband's bankruptcy. (We are still together, but finances are separate).
I know I am incredibly lucky to be where I am and not many women are in my position. I come from an ordinary working family, no inheritance, no help with getting on the housing ladder. But there is no doubt I have been fortunate.
Is this a boast, yes probably, but I am proud of where I am and I would tell any young woman prioritise your financial security. It can be done.
