Why switch rate with A Mortgage Now?

Secure a better rate online, it's simple, fast and hassle free

Switching to a new Santander mortgage rate is usually a quick and straightforward process for existing customers. Our free mortgage product transfer service helps you secure a new mortgage rate while making the application process simple and efficient.

What we need from you

To arrange your Santander mortgage product transfer, we will normally require:

  • Your Santander mortgage account number.
  • Your full name.
  • Your contact details.
  • Your date of birth.
  • The postcode of the mortgaged property.

How our Santander mortgage switch process works

  • Once we receive your enquiry, we will obtain details of your current mortgage and all available Santander mortgage products.
  • Within one working day we will email you a clear summary of your existing mortgage together with all of your available mortgage rate options.
  • We will explain the available products, answer any questions you may have and help you select the most suitable mortgage rate.
  • Once you have made your decision, we will arrange your Santander mortgage product transfer.
  • Santander will then issue your mortgage offer electronically for you to review and accept.

Mortgage product fees

We do not charge any broker fees for arranging Santander mortgage product transfers.

Some Santander mortgage products include a lender product fee, while others are available with no product fee, allowing you to choose the option that best suits your circumstances.

When will my new mortgage rate start?

If you are currently on Santander's Standard Variable Rate, Follow-on Rate or another eligible variable rate, your new mortgage product can normally begin immediately.

If you are still within an existing fixed-rate incentive period, your new mortgage product will normally begin when your current mortgage deal ends. In some circumstances, where your new mortgage rate is no higher than your existing rate, Santander may allow the new rate to start immediately without applying an early repayment charge.

Can I change my mind?

If you secure a new Santander mortgage product early and Santander subsequently launches a lower rate, you can normally change to the new product or cancel your reserved deal provided your new mortgage product is not due to start within the next 14 days.

When we may not be able to help

Our standard Santander mortgage product transfer service may not be suitable if:

  • You wish to borrow additional funds.
  • You want to change your mortgage term.
  • You want to add or remove a borrower.

  • Your mortgage is a Santander Flexible Offset mortgage.

  • We explain your options in clear, straightforward language.
  • We manage your application from start to finish.
