Yes, almost all mortgage providers will normally charge what is known as an early repayment charge' if you decide that you can, and wish to pay the whole balance of your mortgage off early. This is essentially because in doing so, you are losing the lender money in interest that you would otherwise be paying over the course of the term. On some repayment mortgage plans, you will be allowed to make overpayments each month, that is, paying more than your usual monthly repayment. Overpayments are typically allowed up to 10% above your standard monthly payment, but again this will depend on each particular mortgage plan, so always check with your lender if you are unsure.
