Porting Your Mortgage | What You Need to Know.  Moving home doesn’t always mean starting a new mortgage. Many homeowners choose mortgage portability, which allows them to transfer their current mortgage to a new property.

What Is Mortgage Portability?

Mortgage portability is the ability to move your existing mortgage to a new property without changing your lender or deal. It’s commonly used when moving home and wanting to keep your current interest rate and avoid early repayment charges.

Why Port a Mortgage?

There are several benefits to porting your mortgage:

• Retain Your Current Interest Rate – Especially helpful if you’re locked into a competitive fixed rate.

• Avoid Early Repayment Charges – Most fixed-rate mortgages charge penalties for early repayment; porting can help avoid them.

• Simplified Process – Since you’re staying with the same lender, there’s usually less paperwork and a smoother transition.

For a full overview of why this might be the right choice, see our guide on moving your mortgage when changing homes.

Can Everyone Port Their Mortgage?

Not all mortgages are portable. It depends on your lender, the product, and your financial circumstances. Lenders will still run affordability checks and may refuse portability if your new home doesn’t meet lending criteria.

If you’re considering moving soon, check whether your mortgage is portable before making any decisions. Review your original mortgage documents or contact your lender directly.

When Not to Port

In some situations, applying for a new mortgage could be better:

• Better Deals Available – Interest rates may have dropped since your original agreement.

• You Need to Borrow More – Your lender may require a new top-up deal at a different rate.

• Your Financial Situation Has Changed – A significant change in income could impact your eligibility for porting.

Explore both options and speak with a broker to compare the costs of porting vs. switching.

Tips for a Smooth Mortgage Port

• Get Pre-Approval Early – Start the conversation with your lender before making an offer on a new home.

• Check for Fees – While porting avoids early repayment charges, some lenders may charge admin or valuation fees.

• Time It Right – Align your move dates with mortgage timelines to avoid bridging loans or delays.

FAQ | Porting Your Mortgage

Question	Answer
What does porting a mortgage mean?	Porting a mortgage means transferring your existing mortgage deal to a new property when you move home.
Can I port my mortgage to any property?	Not always. Your lender will assess the new property’s value, condition, and your affordability before approving the port.
Do all mortgages allow porting?	No, not all mortgage products are portable. You’ll need to check your original mortgage agreement or ask your lender.
Will I need to reapply to port my mortgage?	Yes. Although you’re staying with the same lender, they will still conduct affordability checks and reassess your circumstances.
Can I borrow more when porting my mortgage?	Possibly. You may be able to borrow more, but the extra borrowing might be at a different rate or require a separate mortgage product.
Are there fees for porting a mortgage?	Some lenders charge admin, valuation, or legal fees, even if you avoid early repayment charges.
Is porting better than getting a new mortgage?	It depends. If your current rate is competitive and your deal has exit penalties, porting may be better. Always compare options.
How long does porting take?	It typically takes a few weeks, depending on the lender, property valuation, and how quickly paperwork is submitted.
