1 % per annum on £100k .. I have just had a very sick feeling. That doesn't even beat inflation.
If you dont need the money immediately why not speculate a little and think about the longer term. Spread the risk and consider a international investment or unit trust. Over the medium to long term you would be hard pushed to not blow any bank rate out of the water.
You dont need a financial adviser, just do your own research and be comfortable with your level of risk.
You dont need to invest everything, but as you dont need the money at short notice, it wouldn't hurt to speculate a little. Or you can leave it where it is and accept that it devalues daily.
Ask Peter Pendant if he remembers a share I told him about a couple of years ago .. today in 8 hours, it went up by 24.44% .. that would have taken more than 20 years if my money had been in the bank.
(Be interesting to know if Peter followed it).
