How does remortgaging work?

When you take out your original mortgage product with the lender. After a certain length of time it will come off that mortgage product, and go on to the lender’s variable rate. This is often quite a lot higher than the initial mortgage you’ve taken out.

The idea of a remortgage is for the broker to search the whole market and get you a new deal. This could either be with a new lender, or with the existing lender.
