It will obviously depend on your daughter's age and when you want her to be able to draw the money. If you are a trustee there may be a clause in the trust deed which limits where you can invest to ensure it's a relatively safe investment. If you have more than 5 years to run I'd be inclined to select a reliable unit trust (or a number of them to split the risk). If she's over 18 she can hold the money in an Equity ISA, (drip feeding the money in to use up her �7,000 allowance every year) but then she'll be able to get her hands on it imediately which may not be what you want to happen. On the other hand, if she's already working, probably the best investment would be to help her buy her own property with it. I'm not a financial advisor so if you feel uncomfortable with money you should consult an expert.
