What Does “Porting” a Mortgage Mean?
Porting your mortgage means moving your existing mortgage deal from your current property to your new one.
So instead of switching to a new deal, you keep:
- Your current interest rate
- Your current lender
- Your existing terms
At first glance, it sounds like an easy win, especially if you’re on a good rate.
When Porting Might Work Well
Porting can be a great option if:
✔ You’re on a low fixed rate you don’t want to lose
✔ Your current deal still has time left
✔ You want to potentially avoid early repayment charges (depending on timing and lender criteria)
✔ Your circumstances haven’t changed significantly
In these situations, keeping your current deal could save you money.
What People Don’t Always Realise
Here’s the important bit, porting isn’t automatic.
Even though you’re staying with the same lender, you’ll still need to:
- Reapply for the mortgage
- Pass affordability checks again
- Meet the lender’s current criteria
So if your income, employment, or financial situation has changed, it could affect your options.
What If You Need to Borrow More?
This is where things can get a bit more complex.
If your new home is more expensive, you may need to borrow additional funds.
This often means:
- Keeping your current mortgage on your old rate
- Taking out a second part of the mortgage at a new rate
So you could end up with two different rates running side by side.
When Getting a New Mortgage Might Be Better
Sometimes, starting fresh is the smarter move.
This could be the case if:
✔ Better deals are now available on the market
✔ Your current rate is no longer competitive
✔ Your circumstances have improved (e.g. higher income)
✔ You want a simpler, single mortgage product
A new mortgage can give you more flexibility and potentially better overall value.
So… Which Option Is Best?
There’s no one-size-fits-all answer.
It depends on:
- Your current mortgage deal
- Your property value and equity
- How much you want to borrow
- Your financial situation today
This is why it’s so important to look at both options side by side before making a decision.
