Make a one-off overpayment

A one-off overpayment is when you make an extra payment on top of your monthly mortgage payment.

Making an overpayment will:

Reduce your mortgage balance.
Save you interest.

Important: You’ll still need to make your normal monthly mortgage payment, and you can’t get a refund on any overpayments you make.

How it works

Making overpayments will reduce your mortgage balance. Any overpayments won’t automatically reduce your mortgage term or monthly payment. But when we next recalculate your monthly payments, we’ll use your new balance. Your term will remain the same. We stop charging interest on any amount you overpay by on the day we receive the payment. So, you’ll owe less and have less interest to pay. As your balance goes down, so will your Loan to Value (LTV). Your LTV is how much you owe compared to the value of your home as a percentage. If your LTV is lower, you could be eligible to apply for lower rates if you switch to a new deal or remortgage to a new lender.

Overpayment limits and early repayment charges (ERCs)

Where ERCs apply, you can make overpayments of up to 10% of the amount owed as of 01 January. We call this your overpayment allowance, and it includes all regular and one-off overpayments you make during the year.

If you pay more than your overpayment allowance, you’ll have to pay a fee

To find out out how much of your overpayment allowance you have left, you can request it here or call us on 0345 727 3747. Our lines are open 8am - 8pm Monday to Friday and 9am – 4pm on Saturdays. We’re closed on Sundays and bank holidays.

If you have a hearing or speech impairment, you can contact us using the Relay UK service. There’s more information on the Relay UK help pages. If you’re Deaf and a BSL user, you can use our BSL SignVideo service.

How we calculate ERCs on overpayments
If you overpay more than 10% over the year, we'll only charge you on the balance you overpay above 10%.

As ERCs reduce through the life of your loan, it might be best to wait until your ERC ends or changes before you make a payment. For example, your latest offer letter could show your ERC rate will go down on 01 July. If you make your payment on 30 June, you’ll have to pay more.

If ERCs don’t apply to your mortgage
You can overpay as much as you like without being charged an ERC. But there might be other fees applied if you pay off your mortgage in full.

We can change our yearly overpayment allowance at any time
Please check before you make any overpayments.

We’ll always give at least three months’ notice before making any changes to your overpayment allowance. We can change your overpayment allowance at any time.

- Sort code: 30-00-00
- Account number: 00332275
- Account name: Halifax
For the payment reference, please input your mortgage account number, plus an extra ‘00’ on the end, so it’s 16-digits in total.

To make an overpayment to a sub-account, replace ‘00’ with the two-digit sub-account number instead. For example, ‘02’. To learn more, visit How do I apply my overpayment to a specific sub-account?
By phone expandable section

To make a one-off overpayment by phone, call our automated phone line on 0345 727 3747. You'll need your 14-digit mortgage account number to hand. Once complete, you can request a text message to confirm your payment.

Once you’ve made your overpayment and would like to apply it to a specific sub-account, you’ll need to call the same number as above and choose an option where you can talk to us. We’re available Monday to Friday 8am - 8pm and Saturday 9am - 4pm. We’re closed on Sundays and bank holidays.

Good to know: The most you can overpay by phone in one go is £60,000, but you can make more than one payment per day. Otherwise, consider our other options or come and see us in branch.
