Additional borrowing on a NatWest mortgage

What is additional borrowing?

Additional borrowing allows you to apply for more money on your existing mortgage for an agreed purpose. Let's take a look at some of the key details.

You're eligible to apply if:

  • You have a mortgage with NatWest.
  • You're a resident in the UK.
  • You're looking to borrow between £10,000 and £500,000 (there may be other more suitable borrowing options. Visit our borrowing needs tool to find out more)
  • You're up to date with your current mortgage payments.
  • You're looking to borrow for a minimum term of 3 years.
  • You've made at least one payment on your existing mortgage.​​

How do I apply?

You can now apply for additional borrowing on your residential mortgage online or through the app. Alternatively, you can call us to speak to one of our qualified mortgage advisers.

Need to make your current debts more affordable?

We can consider lending you money to pay off a number of existing debts and bring together under a single payment with your mortgage. This is known as 'Debt Consolidation'.

Apply online

For residential mortgages, if you are confident in making the decision yourself, you can apply via the app or through online banking.

However, if you have:

  • Debts you wish to consolidate onto your mortgage.
  • An element of your existing mortgage on an interest only repayment.
  • A mortgage that is part of a 'Help to Buy', shared equity, shared ownership or 'Right to Buy' scheme.

 

You can still receive an indication of costs for any new borrowing via our online application but you will need to speak to one of our qualified mortgage advisers in order to consider your application.


If you have:

  • A Buy to let mortgage
  • A Power of Attorney
  • A guarantor or 3rd party on your mortgage

You will need to call us to speak to our mortgage team to consider your application.

  1. On your mobile or tablet, open the camera and point your device at the QR code.
