If you’re thinking about moving home but still tied into a fixed mortgage deal, you might be wondering whether you can take your current mortgage with you.

This is known as porting a mortgage, and it’s something many homeowners ask about when looking to move without paying early repayment charges.

As a mortgage broker in Newcastle, we often help clients explore whether porting their mortgage is the right option, or whether it makes more sense to switch to a new deal entirely.

What does porting a mortgage involve?

Porting a mortgage in Newcastle means transferring your existing mortgage deal to a new property. You keep the same lender, interest rate, and product terms, which can be helpful if you’re still within a fixed or discounted period and want to avoid early repayment fees.

In many cases, porting allows you to move home without having to pay off your mortgage early and take on a new one straight away. That can make a big difference if your current deal is competitive or if you’re trying to avoid extra costs during the move.

Most high street lenders allow this, but it’s not automatic, you’ll need to meet your lender’s criteria again, and approval is subject to affordability checks and the value of the new property.

Are all mortgages portable?

While porting a mortgage in Newcastle is possible with many high street lenders, not every mortgage is portable. Some specialist lenders or older products may not offer this feature, and even if porting is allowed, it’s still subject to approval.

Your lender will assess your new property and your financial situation at the time of application. If anything has changed, such as your income, credit history or outgoings, they may not agree to the transfer, or they might offer different terms.

If you’re unsure whether your mortgage is portable, it’s best to check with your lender or speak with one of our mortgage advisors in Newcastle. We can review your current deal and help you understand what options are available.

Should I port my mortgage in Newcastle?

Even if porting a mortgage in Newcastle is available to you, it’s not always the most suitable option. In some cases, your lender may not agree to lend the extra funds you need to move, or they might offer the additional borrowing on a separate rate that’s less competitive than your current deal.

It’s also worth comparing what’s available on the market. Depending on your circumstances, paying the early repayment charge and switching to a new deal could still work out better over the long term, especially if mortgage rates have improved since you first applied.

Our mortgage advisors in Newcastle will take the time to compare both routes. We’ll look at your current mortgage deal, your plans for the new property, and whether porting or starting fresh gives you the best value.

What is a mortgage sub-account?

If you’re porting a mortgage in Newcastle and need to borrow more than your current balance, your lender may create a sub-account. This means the additional borrowing is placed on a separate mortgage product, often with its own interest rate and end date.

You’ll still make a single monthly payment, but behind the scenes, your mortgage is split into parts with different terms. This setup can work well in the short term, but it may create some complications later on.

For example, when one part of the mortgage deal ends before the other, you might find yourself trying to remortgage with two different expiry dates. That can make future planning more difficult and could result in part of your mortgage moving onto the lender’s standard variable rate temporarily.

If you’re thinking about borrowing more while porting, we’ll help you weigh up the pros and cons of creating a sub-account compared to starting a new deal altogether.
