Where would you recommend investing £100k for a year? The money is to be used to pay down my mortgage but if I did that straight away would have to pay some heavy early repayment charges. So I'm planning to pay off the max overpayment for this year and when my fixed term comes to an end next year to bring down the balance with the rest. BUT...what do I do with it in the interim with rates as they are? Not looking to take any risks with it so stockmarket is out. Any thoughts?
