We’ve never been in a position to invest money before as we’ve always been saving for something. We’re about to buy a new house (with mortgage) and will still have reasonable savings left over. We will be able to save £600ish a month going forwards but as interest is so low at the moment we are wondering what to do with it. Should we put it straight into mortgage overpayments, or do something else with it, or maybe split across some places? What do you do with yours?
