How an Offset mortgage works
An Offset mortgage can lower your monthly payments or reduce the term of your mortgage, saving you £1,000s in interest payments.
The mortgage will be secured on your home. Your home may be repossessed if you do not keep up repayments on your mortgage.
An Offset mortgage works in a similar way to a standard mortgage, except for the inclusion of an extra feature; an Offset Saver savings account which is attached to the mortgage arrangement. Any money placed in the savings account is automatically deducted from the amount of the mortgage on which interest is charged.
You can choose to offset your savings to reduce the term of your mortgage or to reduce your monthly payments.
How offsetting works
If you borrowed £200,000 and held £40,000 in our Offset Saver account, you would only be charged for the interest due on £160,000. That means by maintaining your payments at the agreed level you are effectively paying back more of your mortgage each month and that can have a dramatic effect on how quickly your mortgage is paid off.
Alternatively, you can decide to benefit from lower monthly payments. This won’t pay off your mortgage any quicker, but will make your monthly payments lower.
You can also overpay your mortgage regularly each month, or from time to time, and that extra credit can be used to reduce your payments at a later date.
You won’t earn interest on the Offset Saver account while it's linked to the mortgage.
Offset mortgage options
We have two offset mortgage options, allowing you to either:
- reduce the term of your mortgage or
- reduce your monthly payments
Option 1 - Term reduction (only available for repayment mortgages)
With this option, your offset savings help you to pay your mortgage off earlier. Offsetting won't have an impact on your monthly mortgage payments, but the interest you save by offsetting your savings means you pay more of the mortgage back each month. Your mortgage balance should reduce faster, and you may be able to pay your mortgage off early.
In this example, the mortgage will be repaid four years earlier, saving you 48 payments of £758. In total that is £36,402 less to repay. Plus, unlike a regular savings account, you pay no tax on the money held in an offset account. The future tax treatment of offset savings accounts may vary.

Option 2 - Payment reduction
With this option, your offset savings allow you to benefit from lower monthly mortgage payments, but you won’t pay off your mortgage any sooner. Interest saved each month will be used to reduce the amount of your next month’s mortgage payment, so the more savings you offset, the lower your monthly payment will be.
As you're using your savings to benefit from lower monthly payments, your mortgage balance and remaining mortgage term will not reduce any quicker than if you were on a traditional non-offset mortgage.
