Well, one big "DON'T." Don't invest in any With Profit Bonds. They are not transparent investments and you are likely to lose some of your capital by having a penalty stamped on it, even though with some of them you can withdraw a certain small percentage (around the Retail price Index of about 3.5%) per annum tax free.
If you need a monthly income, virtually the only viable option would seem to be a high interest deposit account, the best of which are paying between 4.8% and 5% per annum. I'd still transfer �3,000 each year into a cash ISA while they still exist as at least that part of your investment income will be tax free. You could invest �7,000 a year in an Equity Income Unit Trust ISA, buying income units, but that is a stock market investment and with the stock market currently volatile, it would be a risk. If you need to be totally risk free, and you want to take a monthly income, it will have to be a deposit account of some kind.
Best to get an IFA. A bank will probably only recommend their own products which will not necessarily be the best products on the market.
