David Beard, CEO and personal finance expert of financial comparison site, Lendingexpert.co.uk, said: “If your mortgage isn’t on a fixed-rate, first, find out how much your monthly repayments will increase by. If you can’t afford to pay extra, don’t be a sitting duck; talk to your lender ASAP about your options, so you don’t run into trouble down the line. The worst thing you can do is stick your head in the sand”.
