Change your mortgage

Helping you change your mortgage

If you already have a mortgage with us but want to change your deal, there will be no affordability or income checks, no legal or valuation fees to pay and no new Direct Debits to set up.

Check what deal you’re on

If you’re not sure what deal you’re on, or when your fixed rate deal ends, you can find out about it in Online Banking, the mobile app or in your annual mortgage statement. 

In line with the Government Mortgage Charter you can lock in a new deal 6 months before your current fixed rate deal ends. If it’s more than 6 months, you’d need to pay your early repayment charge (ERC) to get out of your current deal early.  

You can find your ERC in Online Banking, the mobile app or in your annual mortgage statement. 

Apply for your new deal online or by phone 

Our rates are the same whether you apply by phone or online so we’ll have given you our best rate whichever option you choose. When you choose your mortgage deal we’ll confirm it with you by email within 3 working days. 

You may have seen in the media that mortgage lenders are withdrawing rates or increasing them but if we’ve offered you a mortgage deal it won’t change as long as you check and accept your offer within the deadline that we give you.

Can I change my deal?

You can change your deal if:

  • you’re within 6 months of the existing deal coming to an end, or
  • you’re on a mortgage product without an early repayment charge, or
  • you’re on our Standard Variable Rate or Follow-on Rate

If you book a new deal that starts on a future date, you can’t make any other changes to your mortgage until the new deal has started. This includes switching to interest only for 6 months or increasing your mortgage term under the Mortgage Charter. You also can’t apply for an additional loan, make an overpayment, start the process of moving home or arrange a new deal for another loan on your mortgage.

Can I cancel a deal I’ve already booked?

Once you’ve accepted your new deal, you can change to a different deal or cancel the one you’ve already booked. You must do this at least 14 days before your new deal starts. You won’t be able to make other changes until your new deal starts.

Can I change deals online or by phone?

This is a brief summary of the 3 different types of mortgages we offer

Fixed rateTracker rateLifetime Tracker
Best for:
For people who want to know how much they need to repay for the next few years




You can fix your deal for 2, 3 or 5 years. During this fixed period your monthly payments will stay the same. After your fixed period you’ll move onto the Santander Standard Variable Rate. If you want to finish your deal early, you may have to pay an early repayment charge.
Best for:
For people who think interest rates might change in the next few years or want to make unlimited overpayments.




You can choose a mortgage with an initial rate period and during this period your rate tracks above the Bank of England base rate. With this type of mortgage your payments may vary. The initial rate period is usually 2 years and after that you move onto the Santander Standard Variable Rate.
Best for:
For those who don’t want to look for a new mortgage deal again or who want to make unlimited overpayments.




With a Lifetime Tracker mortgage your rate will track above the Bank of England base rate for the life of your mortgage term. Your payments may vary with this type of mortgage. 

The graphs are for illustrative purposes only.

For an in-depth comparison of the mortgage types on offer read our guide to mortgages

Repayment mortgage

Your monthly payment covers both the amount you’ve borrowed and interest. So as long as you keep up your payments, your mortgage will be paid off at the end.

Interest only mortgage

Your monthly payment only pays off the interest. You’ll still need to repay the amount you borrowed at the end of your mortgage and will need a separate plan in place to do this (such as an investment or endowment). We may limit the amount you can borrow on interest only.

Combination

You can choose to pay part of your mortgage as repayment and the other part as interest only.
