Ok, so...first off, thanks for the help thus far - I know a lot more than before I posted. A low bar, admittedly, but still...
I'm now leaning much more toward this drawdown business - not just for the possibly better returns, the flexibility also sounds good for my situation. As I understand it, they basically put my pension pot (say £100k) into an investment fund, which is invested in the stock market. I can then take out (pretty much - and putting tax to one side for the mo) what I want, when I want - but it comes out of that investment fund. So if I take out £10k, I have £90k left in my fund. Except that the fund will have been invested in the meantime. It may have grown to £110k - so I get my £10k out, but I still have a fund worth £100k. By the same token, it may have performed badly, falling by 10%, so between that & the £10k I took out, I now have a fund worth only £80k. And so on. With the significant difference vs annuities that when I croak, any value left in my fund goes to my missus, not the company that issued my annuity. Right so far?
Assuming so, would I be right in thinking that in deciding which drawdown plan to buy, I have to think about two factors: the management charges (in the case of my current provider, 0.3%), and the likely investment performance of the underlying fund? And is that where an IFA comes in? Applying his/her knowledge of the market to select (or at least recommend) the drawdown plan that best reflects my appetite for risk vs reward?
Thanks in anticipation for any explanations. BTW, I will also be browsing the MSE forums, as advised; but I do find that as with car mechanics or DIY, I often get replies better pitched to my understanding hereabouts than those from more expert experts on more specialised forums, which I often find baffling/complex. CC people speak my language!
