For a first time investor, some general good advice, would be to choose 1 broadly diversified fund. Put all 10K in there and forget about it. You only need to report capital gains, if you make a profit, when you actually sell the fund. Plus there the first 1,200 euro of profit is tax free.
F&C Investment Trust (FCIT), Scottish Mortgage Investment Trust plc (SMT) and Monks Investment Trust (MNKS) are some examples of broadly diversified funds, but do your own research. Morningstar.co.uk is a good site for researching funds.
Also you should be maxing out your pension before you think about investing after tax money.
