Definition
A product transfer changes the rate or deal while the mortgage remains with the same lender. The process can involve fewer legal and valuation steps than switching lender, but eligibility, advice, fees, product choice and any additional borrowing vary.
Practical example
A borrower approaching the end of a fix can compare the lender's retention products with a full remortgage elsewhere.
Why it matters
A simpler process is not automatically the lowest total-cost option.
