I have just picked up this thread so my ha’porth of advice comes a bit late and there has already been a lot of useful contributions. Just before I retired the boss of the small consultancy company where I worked brought in an IFA to have a chat with the staff about pension planning. It was fortuitous timing for me as it turned out. To cut a long story short I went for an income drawdown pension plan as annuities had become very poor value for money.
The positives are that this scheme is very flexible. You can take as little as you need in the way of pension (you can still work at the same time if you want), the whole pension fund is transferable to your spouse in the event of your death and it can even be bequeathed to your children (subject to usual taxation rules). The downside is that the pension pot is invested in the stock markets which can be very volatile e.g. in the immediate aftermath of the COVID pandemic almost £40K was wiped off the value of my portfolio. (It has partially recovered now, only (!) £15K down). These are exceptional times though and it must be remembered that these are long-term investments. I have been retired for about 15 years and the investments have grown by more than the amounts I withdraw every year so I am happy.
