Changing your mortgage deal?


We no longer offer additional borrowing on our mortgages.

As an existing UCB customer, you can move to one of our current products if your mortgage:

  • Is ending in the next six weeks OR you're currently on one of our revert rates OR you have a tracker product with a switch to fix option.
  • Hasn't been in arrears in the last 2 months.
  • Wasn't regulated by the Consumer Credit Act at the time it was taken out.
  • Has a minimum outstanding balance of at least £1,000.
  • Has a minimum mortgage term remaining of 2 years.

If you have a mortgage with a limited benefit period (such as a Tracker or Fixed rate mortgage) and you change before the period is over, there may be early repayment charges.

You must not be subject to a Bankruptcy Order or Individual Voluntary Arrangement (IVA).

How to switch your mortgage deal

At the end of a fixed, discounted or tracker rate, we'll contact you in writing to let you know what your new payments will be. You'll be invited to call us to discuss our current range of mortgage products.

It’s a good idea to talk to an Independent Financial Adviser (IFA) before committing to a new mortgage deal. If you feel you don’t need independent financial advice, you can switch your mortgage deal directly with us.

How long it will take to change a mortgage product

If you accept our 'offer' by signing and returning it to us, this will then change the interest charge with effect from the first of the following month.

What you should know

The borrow back feature isn’t available on new UCB mortgages. Switching your mortgage to a new deal will result in the removal of this facility.

We'll use a house price calculator to get an indication of how much your property is worth based on price movements in your region. If you believe the value is incorrect, you can request for us to carry out an automated valuation model (AVM). You can do this by emailing the information below to

Please make sure to add the following information and declaration to your email request. This is so we can provide you with an update on when your AVM request has been completed.

  • UCB Account Number
  • Customer Name
  • Security Address

If you have any additional questions, you can call us on 0800 464 3014. Whilst we can provide you with information about our mortgages, we can't advise you or recommend which mortgage may be suitable.

Please note that for our mutual protection and to improve service standards. We may monitor and/or record telephone calls.
