What is a mortgage product transfer, and how is it different from remortgaging to a new lender?
A product transfer means switching to a new interest rate deal with your EXISTING mortgage lender when your current deal ends, without needing a fresh full affordability assessment, credit check, or property valuation in most cases -- remortgaging, by contrast, means moving your mortgage to a completely different lender, which generally does require a full new application, valuation, and affordability check as if you were a brand-new customer.
Full answer
Understanding the distinction between a product transfer and a full remortgage matters significantly for borrowers whose circumstances or the property's value may have changed since they first took out their mortgage, since one route can be much more accessible than the other in some situations. **How a product transfer works** When your current fixed, tracker, or discount mortgage deal is coming to an end, your existing lender will typically write to you (or you can proactively contact them) offering a range of new interest rate deals you can switch to, staying with the same lender -- because you are already an existing customer of that specific lender, the process is usually much simpler and faster than a full remortgage, often not requiring a fresh full affordability assessment, credit check, or property valuation, since the lender already has an existing relationship and security over the property. **How remortgaging to a new lender differs** Remortgaging involves applying to a DIFFERENT lender, effectively as a new customer -- this generally requires a full mortgage application process, including affordability assessment based on your CURRENT income and outgoings, a credit check, and a fresh valuation of the property, since the new lender has no existing relationship with you or knowledge of the property's current condition and value. **Why a product transfer can be valuable if your circumstances have changed** Because a product transfer generally does not require a fresh affordability assessment in the same way a full remortgage application would, it can be a valuable option for borrowers whose financial circumstances have changed in ways that might make a full new mortgage application difficult -- for example, someone who has recently become self-employed, taken a career break, seen their income reduce, or taken on significant new debt might still be able to secure a product transfer with their existing lender even if they would struggle to pass a brand-new lender's full affordability assessment from scratch. **Why a product transfer can also help if the property's value has fallen** Similarly, because a product transfer typically does not require a fresh property valuation, borrowers whose property may have fallen in value (potentially putting them in or close to negative equity, or simply at a higher loan-to-value band than they started with) can often still secure a product transfer with their existing lender, even in situations where a full remortgage application elsewhere might be declined or only offered at a worse rate due to the higher loan-to-value ratio a new valuation would reveal. **Why you might still prefer to remortgage elsewhere** Despite the convenience of a product transfer, it is always worth comparing the rates your existing lender is offering against what is available from OTHER lenders in the wider market, since your existing lender has no obligation to offer you their most competitive available rate simply because you are already a customer -- a full remortgage to a new lender can sometimes secure a meaningfully better rate, particularly if your circumstances and the property's value remain strong enough to qualify comfortably with other lenders too. **Product transfer fees and cashback** Product transfers sometimes have lower or no arrangement fees compared with a full remortgage (which can involve valuation fees, legal fees, and a lender arrangement fee), though this varies by lender and specific product, so comparing the TOTAL cost (interest rate plus any fees) of a product transfer against a remortgage elsewhere, rather than just the headline interest rate, gives a fairer comparison. **Worked example** A homeowner's 5-year fixed mortgage deal is ending, and in the intervening years, they became self-employed with more variable income, and their property's value has fallen slightly due to local market conditions. A full remortgage application with a new lender would require them to pass that lender's self-employed income assessment (often requiring 2-3 years of accounts/tax returns) and a fresh valuation reflecting the reduced property value (potentially pushing them into a higher, less favourable loan-to-value band) -- but because their existing lender offers a product transfer without a full new affordability check or valuation, they can secure a new fixed-rate deal with their CURRENT lender relatively straightforwardly, even though they might have struggled to qualify with a different lender from scratch. **Practical tip** As your current mortgage deal approaches its end date, request product transfer options from your existing lender AND get whole-of-market remortgage quotes from a broker, comparing both the total cost and, importantly, your realistic chances of actually qualifying with a new lender given your current circumstances, before deciding which route to pursue.
