BicMac is correct in that any debts you have should be paid off first as the interest on them is bound to be higher than the interest you would receive on a savings account. If you are a taxpayer and want something totally risk free, you could opt for premium bonds if you want a gamble but you won't receive any interest and with only 3,000 your chances of winning anything are pretty low. The other best option is a Mini Cash ISA but interest rates are forecast to rise again over the next few months so if you want to switch to a higher paying ISA, make sure you pick one without an exit penalty. If you have a mortgage, you could reduce its by paying off �3,000 but make sure this doesn't leave you denuded of "emergency money" as it's recommended that everybody should ideally have 3 months living expenses saved in case of unexpected illness or redundany, etc.
