The survey found that nearly all the respondents claimed while they knew that they did not have to move house just to change their mortgage provider, only a third of them had done so.
The survey also found that nearly half the respondents had not checked to see if they could save themselves money by remortgaging and did not know how much they could save by changing their mortgage provider.
Phil Kennedy, commercial director at Direct Line Financial Services, said: "With such competitive deals on the market, switching your mortgage to a more competitive deal could free up some extra cash that can be used to pay off other debts such as personal loans or expensive credit cards or to boost savings."
