To change your payment date, you can choose one of four dates each month: the 1st, 8th, 15th or 25th.

We usually add your payment to your account on the same day we collect it. We will tell you in advance if your payment amount or date changes.

You may be able to make overpayments on your mortgage, capped at 10% of your balance each year. You can also choose to make regular overpayments of up to £499.99 per month without early repayment charges. 

Your mortgage may allow extra payments. Please check your terms and conditions before sending an extra payments to us.    

Any amount of overpayment will lower your mortgage balance, and you will pay less interest over the term of your mortgage.

Making extra payments won’t shorten your mortgage term. However, they will usually lower your mortgage balance and the interest you pay over time.  

If you want to pay off your mortgage sooner by lowering the term, you’ll need to speak to one of our Mortgage Advisers. This is so they can complete an affordability check and make sure the new payments are right for you. You can book an appointment by completing our online form, or by calling us on 0345 601 0014* (Monday to Friday, 8am to 6pm). Mortgage Advice appointments are available Monday to Friday, 8am to 8pm, and Saturday, 9am to 3pm.  

Redeeming your mortgage means paying off the balance in full. This can happen if:   

• You choose to repay the loan yourself, or   
• You move your mortgage to another lender and they repay us for you   

If you’re thinking about paying off your mortgage in full, you can find more information about how to do this on our page below. 

If you have an interest only mortgage and you change how you plan to repay the full amount at the end of the term you need to let us know.

Please complete our interest only repayment plan form and tell us how you expect to repay the loan.
