ERC stands for “Early Repayment Charges” generally applied on longer term Commercial Mortgages ( to protect the lenders anticipated margin on the deployment of the funds) if the loan is redeemed in the early years. Many lenders will charge ERC’s up to a three or five year point in the loan usually on a reducing scale but these can be as high as 5% of the mortgage amount if a facility is repaid in year 1.
