123456789, as part of the financial review that an independent financial adviser (FA) would carry out with you (all, or each), your own objectives need to be assessed, quantified, prioritised, and recommendations made accordingly. For example, lets say you have 7m yourself. What do you want to achieve with it (ie, do you want a small, medium or large income from it, or do you not need any real income from it right now but would like to see max capital growth for the future?), do you want capital protection, or can you quantify by how much you want to see your capital grow? What is your attitude to risk? eg, if you want capital guarantees (low risk appetite) AND a huge income each year, AND an investment return of 15 to 20%, you need to reconcile these objectives to what is practically available, ie, a low risk appetite (implies low return investments) does not sit well with a desire for a large income (which will deplete the capital over time) and a desire for above average returns (requirement for riskier investments).
Some life companies which offer these investment bonds allow a very wide range of mixed investments, and with a sum as large as 7m, making choices is, relatively, more straightforward. Some will allow, in addition to the usual range of managed funds (a mix of equities - shares) with property, bonds, some cash, some fixed interest) and specialist funds (depending on your investment appetite) a portion of your investment to be invested in direct stock selections, and further, will allow you a choice of execution only (you decide what shares to buy and sell, and when) or discretionary or full advice from stockbrokers. The more you want though, the hiogher the charges. However for the inexperienced investor, these may appear great options, but would probably be totally inappropriate.
The overall point though is that you have to reconcile your attitude to risk with what you want to achieve with your money. A good financial adviser will help, but make sure they are independent, and do not be afraid to discuss up-front ho they will be paid (how much commission they get).
I'm sure you'll get a lot of 'pm' requests when you have 7m to invest, so I'll only say pm me if you want. I am a QFA, and would be more than happy to assist you with no strings attached.
