Actively offset

A customer who 'actively offsets' generally holds an offset mortgage and a current account and/or savings product, makes regular use of the flexible features of these accounts (such as Current Account Transfer Service, paying in a monthly salary), makes regular account transactions, and has a current account and/or savings balance of at least 2% of their mortgage balance.

AER: Annual equivalent rate

AER stands for Annual Equivalent Rate and illustrates what the interest rate would be if interest was paid and compounded once each year. As every advertisement for a savings product, which quotes an interest rate, will contain an AER you will be able to compare more easily what return you can expect from your savings over time.

APRC: Annual percentage rate of Charge

Your Mortgage Illustration will show you the APRC for your mortgage. This is a notional annual interest rate which takes account of fees and charges to reflect the total cost of your mortgage. Your Mortgage Illustration will detail the fees which are included in this calculation. An APRC is calculated using a standard method so it provides an effective way for you to compare quotes from different lenders.

Average balance

The average balance of your current account and savings is used in our calculators to show the benefits of offsetting. In reality, these balances will vary from day to day. Because we calculate interest on the basis of daily balances, we make the most of your money.

You can choose a combination mortgage. This can consist of interest-only parts, repayment parts, or a combination of both of these methods of mortgage repayment.

Please note that for any part of a mortgage which is interest-only, the capital must be repaid by you at the end of its term. Therefore for any such interest-only element, you must make arrangements to set up a savings or investment scheme which will provide sufficient funds to repay the capital.
