What a product transfer is

A product transfer means switching to a new deal with your existing lender when your current deal ends, without moving your mortgage elsewhere. It's often quicker and simpler than a full remortgage, and typically doesn't require a new affordability assessment or legal work.

What a remortgage involves

A remortgage means moving your mortgage to a new lender entirely, which requires a fresh application, a new affordability assessment based on your current circumstances, and usually legal work (though often at reduced or no cost as part of a switching incentive) to handle the change of lender.

The trade-off

Product transferRemortgage
Speed and simplicityUsually faster, less paperworkMore involved, takes longer
New affordability checkUsually not requiredRequired — a change in circumstances could affect what's offered
Access to the whole marketLimited to your existing lender's current dealsFull market comparison possible
Potential savingsMay miss a better deal elsewhereCan capture the most competitive rate available

When a product transfer makes sense

If your circumstances have changed in a way that might make a new lender's affordability check difficult to pass (reduced income, new debts, a lower credit score, or having become self-employed), staying with your existing lender via a product transfer avoids that check entirely, even if the rate isn't the very best on the market.

When a full remortgage makes sense

If your circumstances remain strong and you have time to shop around, comparing the whole market via a remortgage — ideally with the help of a mortgage broker — often reveals meaningfully better deals than simply accepting your existing lender's retention offer.

Key takeaways

  • A product transfer stays with your existing lender, usually without a new affordability check.
  • A remortgage moves to a new lender and typically requires a full fresh application.
  • Product transfers suit changed circumstances that might complicate a new application elsewhere.
  • Full remortgaging usually gives access to more competitive rates if your circumstances remain strong.
