Porting a Nationwide mortgage: what it means for home movers

Porting a Nationwide mortgage: what it means for home movers

If you’re moving home and you already have a Nationwide mortgage, you may be able to transfer (port) your existing mortgage to your new property. This is often called mortgage porting.

For many home movers, porting can be attractive because it may help you preserve parts of what you already have—such as the remaining mortgage term and, in some cases, the deal structure—rather than starting again with a completely new mortgage.

This guide explains how porting works in the context of a Nationwide mortgage, including what happens if you’re porting only part of the loan and what to consider if you need to borrow more.

What does it mean to port your mortgage?

When you port a mortgage, you’re asking your lender to move your existing mortgage to a new property.

Instead of closing your current mortgage and applying for a brand-new one, porting aims to keep:

• the mortgage you already have (subject to Nationwide’s rules)
• the remaining term
• the original deal structure (where applicable)

It’s also important to understand that porting doesn’t always cover everything you need for the next purchase. If the loan amount required for your new home is different from what you currently owe, you may be porting part of the mortgage and dealing with the rest separately.

Where your existing mortgage terms include early repayment charges (ERCs), the portion that isn’t ported may be the part that could trigger them—this depends on your specific Nationwide mortgage terms.

Can you port a Nationwide mortgage?

In many cases, it may be possible to port a Nationwide mortgage when you buy a new property. Whether porting is straightforward will depend on factors such as:

• the type of Nationwide mortgage you currently hold
• the timing of your move
• how much you need to borrow for the new property compared with your current balance
• whether the new property meets the lender’s requirements

Porting when your new home costs less

If your next property is cheaper and you don’t need to borrow the same amount, you may not be able to port the entire mortgage.

In that situation, you may port the amount needed for the new purchase, while any remaining balance is handled differently. If ERCs apply under your current mortgage terms, they may be relevant to the portion that is repaid rather than ported.

Porting when your new home costs more

If you need to borrow more than the amount you can port, you may still be able to port your existing Nationwide mortgage and then arrange additional borrowing for the shortfall.

This is often treated as:

• porting the existing mortgage amount
• arranging a top-up or new borrowing for the rest

The additional borrowing may be on different terms, and the overall arrangement still needs to satisfy Nationwide’s process.

Can you port a Nationwide mortgage and borrow more?

Often, it may be possible to combine porting with additional borrowing as part of the same move.

A typical scenario is:

• port your existing Nationwide mortgage amount
• apply for additional borrowing to reach the total required loan

Whether this is possible in practice depends on how Nationwide structures the arrangement and what it considers suitable for your circumstances.

What happens during the porting process?

Mortgage porting is usually more than a simple transfer. Even though you’re not switching lenders, Nationwide still needs to assess the new arrangement.

In practice, the lender will generally consider:

• your current financial position
• the new property as security
• how the mortgage will be structured on the new purchase

Paper-based process may apply

For some porting applications, the process may involve paper-based steps rather than being fully online. That can affect turnaround times, especially if forms and documents need to be completed and returned.

Affordability and supporting information

Even when you’re moving your existing mortgage, Nationwide will typically carry out an assessment to ensure the arrangement remains appropriate.

You may be asked to provide evidence such as:

• latest payslips
• P60
• bank statements

Having the right documents available early can help avoid delays.

How long does porting take?

Porting timelines can vary depending on factors like the complexity of the application and how quickly documentation is returned.

Where a paper-based element applies, it can add time compared with a fully digital application.

If you’re working to a specific exchange or completion date, it’s sensible to plan for the possibility of extra processing time.

Is porting a Nationwide mortgage straightforward?

Porting can be relatively smooth when:

• you can port the amount you need for the new purchase
• your move doesn’t introduce complications for underwriting
• you can provide documentation promptly

However, porting is still a detailed lender process. It’s important to be clear about what you’re trying to achieve, for example:

• porting the mortgage to the new property
• porting part of the mortgage and arranging additional borrowing

Because the portion that isn’t ported may be treated differently, understanding how the numbers work can help you avoid surprises.

Key considerations for Nationwide mortgage porting

Before you commit to a move, it helps to consider:

1. How much will be ported

   • If your loan amount needs change, you may port only part of the mortgage.

2. Potential early repayment charges (ERCs)

   • Any portion repaid rather than ported may be the part that could attract charges, depending on your mortgage terms.

3. Borrowing more alongside porting

   • If you need a larger loan, top-up or additional borrowing may be possible, but it may be on different terms.

4. Affordability checks

   • Even with an existing mortgage, Nationwide will typically review your current circumstances.

5. Timing and process type

   • If the process involves paper-based steps, planning ahead can make a noticeable difference.

Summary

Porting a Nationwide mortgage can allow home movers to transfer their existing mortgage arrangement to a new property, potentially helping them preserve key features such as the remaining term and, in some cases, the deal structure.

The process usually involves Nationwide assessing the move as part of your overall circumstances, and it may include a paper-based element. Whether you’re porting the full amount or porting part of it and borrowing more, understanding how the arrangement is structured can help you plan your move with greater confidence.
