UK Mortgage Product Transfers: A Complete Guide for 2026/27
When your fixed or tracker mortgage deal is coming to an end, your existing lender will often offer a product transfer onto a new deal — a quicker, simpler alternative to a full remortgage with a new lender. This guide explains how product transfers work and when to consider one instead of shopping around.
What a Product Transfer Is
A product transfer is switching from your current mortgage deal onto a new deal with the same lender, on the same underlying loan balance, rather than repaying your mortgage in full and taking out a brand new one elsewhere. It is the route most borrowers use simply to move from an ending fixed or tracker rate onto a new one, without changing lender.
Product Transfer vs Remortgage
Remortgaging means taking out a new mortgage, usually with a different lender, to repay your existing one — a process that typically involves a fresh application, valuation, and full affordability assessment. A product transfer stays within the same lender and loan, so it is generally faster and involves less paperwork, but it is worth comparing the rate on offer against what a full remortgage to another lender could achieve.
Advantages of a Product Transfer
A product transfer is usually quicker to arrange, often avoids the cost of a new property valuation, and does not require solicitors in the way a remortgage to a new lender does. It also tends to involve a lighter-touch affordability check, which can help borrowers whose circumstances have changed (for example, reduced income or new debts) since they last applied for a mortgage.
Possible Downsides
Because you are staying with the same lender, you will not necessarily be offered the most competitive rate on the wider market, and lenders sometimes reserve their best deals for new customers rather than existing ones. It is always worth comparing your lender's product transfer rate against what else is available before committing.
Affordability Checks
Many lenders can offer existing borrowers a like-for-like product transfer without a full new affordability assessment, under rules that recognise the borrower is not increasing their borrowing or overall risk. This can make a product transfer more accessible than a full remortgage for borrowers whose income or credit position has changed since their original mortgage was arranged.
When to Arrange One
Many lenders let you book a new product transfer rate a number of months before your current deal ends — sometimes up to around six months ahead — which can protect you from rate rises in the meantime. Setting a reminder ahead of your deal's end date, and comparing options in good time, helps you avoid slipping onto the lender's standard variable rate by default.
Borrowing More Alongside a Transfer
Some lenders allow you to borrow additional money at the same time as a product transfer, known as a further advance, but this usually requires a fresh affordability check since your total borrowing is increasing. If you need to borrow more, ask your lender whether this can be combined with a product transfer or whether it needs to be arranged separately.
What Happens If You Do Nothing
If you take no action when your current deal ends, you will automatically move onto your lender's standard variable rate (SVR), which is usually higher than a newly arranged fixed, tracker or discount deal. Reviewing your options — whether a product transfer or a remortgage — before your deal ends can save a significant amount over the following months.
