Product Transfer Mortgages: Costs, Eligibility and Switch Timing
Published 09 June 2026
A product transfer lets you take a new rate with your current lender when your existing deal ends, without moving to another one. With fixed pricing easing through 2026 and lenders passing reductions onto existing customers, the switch deal on offer is often cheaper than it was, but a lower retention rate is not automatically the best outcome once a whole-of-market remortgage is weighed up. This guide covers how product transfers work, what they cost, who qualifies and when a remortgage is the stronger move.

What is a product transfer mortgage?
A product transfer is a new mortgage deal taken with your existing lender when your current rate ends, keeping the same loan and property. It usually needs no legal work and no move to another lender, the balance stays the same, and it is sometimes called a product switch or rate switch rather than a full remortgage.
The alternative to arranging a new deal is doing nothing, which usually means rolling onto the lender's standard variable rate when the current deal ends. That rate is typically higher and can move at the lender's discretion, so most borrowers arrange a new rate in advance rather than let the deal lapse. A product transfer is the simplest way to do that with the lender you already have.
Because the loan, lender and property all stay the same, a like-for-like product transfer is light on paperwork. There is usually no new valuation, no conveyancing and no fresh full application. That simplicity is the main appeal, and it is why a transfer can complete quickly compared with moving to a new lender.
Product transfer or remortgage: which is right for you?
A product transfer suits borrowers keeping the same loan amount who value speed and simplicity, while a remortgage to a new lender can win on total cost, extra borrowing or better criteria. The right choice depends on fees, your loan-to-value, any early repayment charge and whether you need to change the loan, not on the label.
A product transfer tends to make sense when the balance is staying broadly the same, your circumstances are straightforward and the lender's new rate is competitive once any fee is included. It can also be the pragmatic route if your credit profile or income has become harder to evidence since the original mortgage, because a like-for-like switch usually avoids a fresh affordability assessment.
A full remortgage is worth comparing when you want to raise capital, your loan-to-value may have improved, you need a different term or features, or a new lender prices your case more keenly. The decision matters because a product transfer only compares one lender's deal, whereas a remortgage opens up the whole of market. A structured remortgaging guide and a like-for-like cost comparison, including fees and any incentives, will usually show which route is genuinely cheaper.
If the only goal is to borrow more while keeping the existing mortgage in place, additional borrowing alongside a product transfer can sometimes beat a full remortgage, so it is worth comparing both before assuming you have to move lender.

Can you be declined a product transfer?
Most straightforward product transfers do not need a new affordability assessment, so they are rarely declined on income grounds. A transfer can still be refused or restricted if you are in arrears, want to change the loan amount or term, or the lender has withdrawn the product, in which case a remortgage may become the better route.
For a like-for-like switch on the same balance and term, lenders generally do not re-run a fresh affordability assessment, which is why a transfer is usually available even if your income would no longer pass one. This is one of the strongest reasons a transfer can be the right call for self-employed borrowers, those between jobs, or anyone whose paperwork has become more complex.
The picture changes once you ask for more than a like-for-like switch. Porting to a new property, raising the loan, extending the term or moving onto a different repayment basis can all trigger underwriting closer to a full application. Active arrears, or the lender simply pulling the product you wanted, can also limit what is offered, so it is worth lining up the switch in good time.
When can you do a product transfer? The switch window
Most lenders let you reserve a product transfer up to six months before your current deal ends, with the new rate starting when the old one finishes. Acting early protects you if pricing rises, and many lenders will move you to a lower rate of their own if deals improve before your switch completes.
Reserving early is close to risk-free because the rate you secure does not start until your current deal finishes, and most lenders allow a switch to a cheaper rate if one appears before completion. The practical risk runs the other way: leaving it too late can mean a spell on the standard variable rate, which is usually the most expensive place to be.
Why product transfer rates are moving in 2026
Product transfer pricing follows the wider fixed-rate market, which has eased through 2026 as swap rates fell. Several lenders have passed reductions onto existing customers, so the retention deal on offer today may be lower than a few months ago, though it can still be beaten by a new lender once the whole of market is compared.
Lenders have repriced repeatedly through the year rather than in one move, part of the run of rate cuts through 2026 across the market. Virgin Money reduced selected residential and buy-to-let product transfer fixed rates, passing cuts directly to existing borrowers rather than reserving them for new customers.
TSB has also cut across its range, including residential and buy-to-let product transfer deals alongside new-business and additional borrowing pricing. For anyone near the end of a deal, the message is that the retention rate on the table is a moving target, and checking it against current market rates before accepting is rarely wasted effort.
Whether to lock in a transfer now or wait depends on where pricing goes next, which is why our rate forecast is worth a look before deciding. Landlords have seen the same pattern, with buy-to-let product transfer rates among those cut, so the same comparison applies to a buy-to-let mortgage held with an existing lender.

FAQs
What is the difference between a product transfer and a remortgage?
A product transfer is a new deal with your existing lender, keeping the same loan and property with little paperwork. A remortgage moves the mortgage to a new lender, which can cost more in fees and time but may offer a better rate, extra borrowing or different terms.
Do you need a solicitor for a product transfer?
Usually not. Because the loan and lender stay the same, a standard like-for-like product transfer does not normally involve legal work. A remortgage to a new lender does typically need conveyancing, though many remortgage products include a free legal package.
Does a product transfer need an affordability check?
A straightforward product transfer on the same loan amount usually does not require a full affordability assessment. A check is more likely if you want to borrow more, extend the term or make other changes, which can move the case closer to a full application.
Can you borrow more money with a product transfer?
Not through the product transfer itself. Extra borrowing is usually arranged as additional borrowing alongside the transfer, or through a remortgage. Each is assessed on affordability, so the simplicity of a like-for-like switch no longer applies once you raise the loan.
Can you switch to a different lender's deal after reserving a product transfer?
Not to a rival lender's deal, but many lenders let you move to a lower rate of their own if pricing falls before your switch completes. That is one reason to reserve early rather than wait, since it protects you if rates rise and lets you benefit if they fall.
How long before my deal ends can I arrange a product transfer?
Most lenders let you line up a product transfer in the months before your current deal ends, with the new rate starting when the old one finishes. Reserving early gives certainty and, with many lenders, the option to switch to a cheaper rate if one appears first.
Is a product transfer always cheaper than remortgaging?
No. A retention deal can be competitive, especially for a like-for-like switch, but it only reflects one lender. A remortgage compared across the whole of market can be cheaper overall once rate, fees and incentives are weighed, which is why both are worth comparing.
