What Does It Mean to Port Your Mortgage?

What Is Porting a Mortgage?

Porting a mortgage simply means transferring your existing mortgage deal (including your interest rate and lender) from your current property to a new one. Essentially, you're taking your mortgage with you when you move.

It sounds simple—and in many cases, it can be—but there are a few important things to consider.

Why Do People Port Their Mortgage?

Porting is often a popular option for people who are:
✅ On a competitive fixed or tracker rate they want to keep
✅ Facing Early Repayment Charges (ERCs) if they end their deal early
✅ Looking to move before their mortgage term is up

By porting your mortgage, you can hold onto a good rate and avoid additional fees—what’s not to like?

How Does It Work?

Even though you’re staying with the same lender, you’ll still need to apply to port your mortgage. Here’s what typically happens:

  1. You apply for permission to port.
  2. Your lender reassesses your affordability for the new property—just like a standard mortgage application.
  3. The new property is valued, and your lender ensures it meets their lending criteria.
  4. If approved, your mortgage deal moves with you.

If your new home is more expensive than your current one, you may need a top-up mortgage for the difference—this might come with a different interest rate.

Things to Watch Out For

While porting can be a great option, it’s not always the best choice. Keep in mind:

  • Not all mortgages are portable—check your deal's terms.
  • You’ll still go through the full affordability and credit checks.
  • If you're borrowing more, the additional amount may be on a higher rate.
  • You could miss out on better deals by not exploring the wider market.

Should You Port or Look for a New Deal?

This really depends on your circumstances—how much you’re borrowing, your current deal, and what’s available on the market.

Sometimes, paying an Early Repayment Charge to access a more competitive deal actually saves money long-term. Other times, porting is the most efficient way forward.
