You can take advantage of up to £3,600 per tax year by investing in a stocks and shares ISA, but be aware that if you go down this route you need to be prepared to lock your money away for five to ten years, so as to ride out current volatility in the stockmarket. You may see your investment fall in value too, so think about whether or not you want to invest your £2,000 lump sum outright or make smaller regular monthly investments. However I would recommend you speak to an independent financial adviser first.
