How much can I overpay on my mortgage?

  • If you’re on a fixed or tracker rate product, you can pay up to 20% of your outstanding balance for each of your sub-accounts before an Early Repayment Charge (ERC) will apply. If you exceed your allowance, you’ll have to pay an ERC on the amount over 20%. To find out what this means for you, log in to Manage your Mortgage and select “Make an Overpayment”.
  • If you’re on our Standard Variable Rate (SVR), there’s no limit to how much you can overpay, and there’s no ERC.

Regular overpayment           

  • This is a regular payment you make every month on top of your monthly direct debit.
  • You must continue to make your normal mortgage payment in full each calendar month.
  • If you pay more than 20% of your outstanding balance, we’ll cancel your regular overpayment so that you don’t pay an ERC.
  • Monthly overpayments will reduce your mortgage balance and could help save you interest.
  • You can set-up, amend, or cancel your regular overpayment by logging in to Manage your Mortgage.

Lump-sum overpayment           

  • This is an additional payment that you can make at any time.
  • You can make lump sum payments as often as you like, but if you exceed your overpayment allowance, you’ll have to pay an ERC on the amount over 20%.   
  • If you pay £1,000 or more, your monthly payment will be recalculated.
  • If you want to pay off your mortgage or you have less than £500 remaining, you’ll need to request a redemption statement by logging in to Manage your Mortgage and selecting the Redemption menu.

Important information

If you are not on our Standard Variable Rate (which has no restrictions on the amount you can overpay), there may be a maximum value amount you can overpay each year without incurring an Early Repayment Charge. For more information please refer to your most recent mortgage offer.

To illustrate savings, we have made the following assumptions:

  • The amount you currently pay is based on either your previous monthly payment or the information you have entered.
  • Monthly overpayments are made and remain constant throughout the mortgage term.
  • The interest rate will remain the same for the term of the mortgage.
  • Months are of 12 equal lengths so the monthly interest will not differ.
  • Repayment amounts are rounded up or down accordingly to the nearest £1 for display purposes.
  • The potential reduction in time to repay your mortgage is presented as years/months. The figure is rounded up or down accordingly for display purposes.

The calculator is for illustrative purposes only. It does not provide a precise calculation of the time or interest you could save, but is intended to give you information and guidance about the potential savings. Please note the calculator does not factor in any charges for early repayments of the total mortgage balance and is based on a capital repayment mortgage. This overpayment calculator does not include all of the information that you need to select or compare mortgages. Please request a Mortgage Illustration before you choose a mortgage.

Your home or property may be repossessed if you do not keep up repayments on your mortgage.
