The majority of our residential mortgage products are normally portable, unless specifically stated otherwise. This means that the benefits of your client’s existing mortgage (up to the outstanding balance of their current mortgage) can be transferred to their new home, subject to our lending criteria at the time of any move. For porting applications, any early repayment charges will not be charged but the existing interest rate will not apply to any additional funds your client borrows unless it is our Standard variable rate.

If you need help, please visit the FAQs section or call our Broker Liaison Team on 01634 835791.

New applications for existing borrowers

For new applications on behalf of existing BTL borrowers* we will only require the following:

  • A completed application and declaration form;
  • Valuation report;
  • Written confirmation from the borrower that their circumstances are unchanged.

A fresh credit search will be carried out to ensure that the credit profile still meets required lending policy. If the borrower's circumstances have changed, the underwriter will retain the right to request additional information.

*The reduced document requirement only applies to existing borrowers whose last loan completed within the last 12 months and where the standard required documentation was provided. 

Transfer of Equity

If your client's circumstances change and they want to add or remove a borrower from the property title or transfer ownership of a property, our mortgage operations team are on hand to help. You can contact the team on 0345 122 0033.
