A product transfer is a new mortgage deal taken with the borrower’s existing lender, switching from the current rate to a new product within the same lender’s range without moving the loan to a different provider. It is the structurally simpler counterpart to a remortgage, where the loan moves to a different lender on a fresh mortgage contract. Both are common refinancing routes when a fixed-rate or other deal period approaches its end, and the choice between them depends on the borrower’s circumstances and lender criteria.
This extended definition explains what a product transfer is, how it differs from a remortgage, and the regulatory framework that distinguishes the two routes under FCA rules. It does not address which option is preferable in any given case, as that is a matter of individual circumstances.
Key Insights
- A product transfer is a rate switch with the existing lender; the loan, property, and legal owner all remain in place, and what changes is typically the rate, term, and sometimes the product type.
- A remortgage is a new mortgage contract with a different lender; the new lender redeems the existing mortgage at completion and registers a fresh legal charge on the property.
- Under FCA MCOB 11.6.3R, a same-lender rate switch without additional borrowing is exempt from the full affordability assessment that applies to a new mortgage contract.
- For UK expats and non-resident borrowers, lender appetite for a product transfer can change once the borrower has moved abroad, and the practical availability of either route varies by lender.
What a Product Transfer Covers
A product transfer is a contract variation with the same lender. The mortgage account remains in place, and the loan continues on its existing terms with a new rate, often a new term length, and sometimes a new product type. Because the legal owner of the property and the registered mortgage charge do not change, conveyancing is not normally required, and a fresh property valuation is typically either not requested or carried out as a desktop valuation.
The streamlined nature reflects FCA rules. The lender does not generally carry out a full affordability assessment where the borrower switches rate without increasing the amount borrowed. Lender eligibility checks still apply, including a credit check in many cases and confirmation that the borrower’s circumstances have not changed materially. Where additional borrowing is needed alongside the rate switch, that further amount is typically arranged separately as a further advance, which does carry an affordability assessment in its own right.
Completion timelines for a product transfer are usually short, often days to a few weeks. Documentation is typically light, and product fees may apply on the new product but legal and valuation costs are typically nil.
How a Product Transfer Differs from a Remortgage
A remortgage moves the mortgage to a different lender. The new lender carries out a full affordability assessment, applies an interest rate stress test where applicable, and instructs a property valuation. Conveyancing is involved on both sides: the existing mortgage is redeemed at completion, and the new charge is registered with HM Land Registry. Following the FCA’s Policy Statement PS25/11 (July 2025), a Modified Affordability Assessment can apply on certain external switches at the lender’s discretion, where the new mortgage is more affordable than the existing arrangement; this is permissive rather than automatic.
The headline distinction is choice. A product transfer is limited to the current lender’s range, while a remortgage opens the wider market. The trade-off is structural simplicity against lender choice, and the practical implications differ between borrowers.
Frequently Asked Questions
What is the difference between a product transfer and a remortgage?
A product transfer is a new rate with the same lender, typically without conveyancing, full affordability reassessment, or a fresh valuation. The mortgage account, the registered charge on the property, and the legal owner all remain in place. A remortgage is a new mortgage contract with a different lender, which involves redemption of the existing mortgage at completion, full underwriting on the new application, and conveyancing to register the new charge. Product transfers are typically faster and structurally simpler; remortgages open access to the wider market and to lenders the borrower is not currently with. The FCA framework treats the two routes differently, with same-lender rate switches exempt from the full affordability assessment that applies to a new mortgage contract.
Are product transfers available to UK expats living overseas?
Many UK lenders restrict product transfers to UK-resident borrowers, meaning a borrower who moves abroad after taking out the original mortgage may find a product transfer is no longer available with that lender at the next deal end. Some lenders permit product transfers for existing customers regardless of residence, while others narrow eligibility to UK-resident borrowers only, and some apply a different overlay where the borrower has moved to a country outside their accepted-country list. Where a product transfer is not available with the existing lender, the alternative is typically a specialist expat remortgage with a lender that accepts overseas-resident applicants. Lender appetite varies considerably across the specialist expat market, and individual borrowers’ positions depend on country of residence, currency of income, and the existing lender’s policy on overseas customers. Documentation requirements typically expand for expat remortgage applications compared with UK-resident equivalents.
Does a product transfer involve a fresh affordability assessment?
Generally no, where the rate is switched without additional borrowing. Under MCOB 11.6.3R, the standard affordability rules do not apply to a same-lender rate switch where the amount borrowed does not increase. Lender eligibility checks may still apply, including a credit check and confirmation that material circumstances have not changed. Where the borrower wants to add further borrowing alongside the rate switch, the additional amount typically goes through an affordability assessment in its own right as a further advance. The exemption applies to the rate switch element only, not to any new borrowing layered on top. The position can also differ where the borrower’s circumstances have changed materially since the original application, for example in cases involving a change of residence, employment status, or the addition or removal of a borrower from the mortgage. In those cases, the lender’s eligibility checks may extend beyond a standard product transfer process.
