How does a Santander product transfer work?
When your current Santander mortgage deal ends, Santander will offer you a new rate from their own range. This is called a product transfer, or rate switch. The process is straightforward: no solicitor, no full valuation, and in most cases no affordability reassessment.
Here is how the timeline typically works:
Around four months before your deal ends, Santander will contact you directly to let you know your options. At this point, you will become eligible to reserve a new deal in advance. If you have not acted by around two months before your deal ends, Santander will contact you again as a reminder.
The booking window is just over four months. That means you can lock in a new rate roughly four months before your current deal expires, with the new rate activating automatically when the old one ends. You will not need to do anything further once the deal is confirmed.
If rates fall after you have booked, Santander allows you to cancel a pre-booked deal and switch to a lower rate, provided you do so at least 14 days before the new deal is due to start. This flexibility can be useful if the market moves in your favour between booking and completion.
The early switch option is a notable feature of Santander's process. If the new rate you are moving to is lower than your current one, Santander will allow you to start the new deal immediately rather than waiting for your current deal to expire. There are no early repayment charges in this scenario. However, if you choose to start early, the deal is binding from that point and cannot be changed or cancelled. There is no cooling-off period.
No income or affordability checks are carried out for a standard product transfer. Because you are already an existing Santander mortgage customer, they use the repayment history on your account rather than reassessing your income. This is one of the key advantages of a product transfer over moving to a new lender.
Use our repayment calculator to get an idea of what a new rate could mean for your monthly payments before we speak.
Your rates are personalised. Santander does not offer the same product transfer rates to every customer. The deals shown to you are based on your individual mortgage, so you have no way of knowing just from Santander's website whether what you are being offered is competitive. This is one of the most practical reasons to use a broker - we can tell you straight away how your personalised Santander offer compares to the wider market.
What about the Standard Variable Rate? If your deal ends and you have not reserved a new one, Santander will move you onto their Standard Variable Rate (SVR) or Follow-on Rate, which is almost always significantly higher. If you are already on the SVR, you are eligible to do a product transfer at any time, not just around your deal end date.
For many homeowners, particularly those in unstable financial circumstances or with limited equity, a product transfer can be the most practical and cost-efficient option. But it's not automatically the right choice, which is why it's worth speaking to an adviser about your options.
What if you want to make changes at the same time?
A product transfer with Santander covers a straight like-for-like rate switch. If you want to make any of the following changes at the same time, the process becomes more involved:
Extending or reducing your mortgage term
Borrowing additional funds (this becomes a separate additional borrowing application with Santander)
Switching from repayment to interest only, or vice versa
Changing the names on the mortgage
Santander requires these changes to be handled separately from the product transfer itself. In some cases, this means a full affordability assessment and, where you are borrowing more, a full mortgage application. This is also the point at which it is worth checking whether the whole market offers something better, since a remortgage to a new lender might open up more options alongside whatever structural changes you want to make.
We charge a fee of £495 for advice involving structural changes. We will always explain this before you commit to anything.
Santander Product Transfer vs Remortgage
Santander's retention rates are generally competitive. They also have a policy that their product transfer rates will always be the same as or lower than the remortgage rates they show to new customers. That is a genuine commitment and it means switching internally will rarely cost you more than going to Santander directly as a new borrower.
That said, the right question is not just whether Santander's rate is fair, it is whether the rate is the best available to you across the whole market. We have access to over 90 lenders. Sometimes the answer is to stay with Santander. Sometimes it is not. We will run through both with you and give you a straight recommendation.
We do not charge a fee for a like-for-like rate switch. Our standard advice fee of £495 applies when structural changes are involved.
Not sure whether a product transfer or a remortgage is the right move? Our guide to fixed vs tracker mortgages can also help if you are deciding which type of rate to take. We cover the full range of mortgage options and can talk you through the numbers at no cost.
Frequently Asked Questions
Can I do a Santander product transfer through a broker?
Yes. Santander accepts product transfer applications submitted by registered mortgage intermediaries. There is no disadvantage to using a broker. Santander's policy is that the rates available through a broker are the same as those available directly. We handle the process on your behalf and compare Santander's offer against the wider market before recommending a course of action.
When does Santander allow me to start looking at new rates?
You become eligible to reserve a new product transfer deal with Santander just over four months before your current deal ends. Santander will contact you directly at four months to let you know your options, and again at around two months if you have not yet acted. We recommend speaking to us at least four months before your deal ends so we have time to review everything properly without any last-minute pressure.
Does Santander do a credit check for a product transfer?
No. Santander does not carry out a new income or affordability assessment for a standard product transfer. They use your existing account history instead. If you want to make structural changes at the same time, such as borrowing more, a full application is required and a credit search will be carried out.
Can I switch to a lower Santander rate early if one becomes available?
Yes, within certain conditions. Once you have booked a new deal, Santander allows you to cancel and rebook up to 14 days before the start date, providing you do not have a product fee that was paid upfront (in which case the process goes via email rather than online). If the new rate you choose is lower than your current deal, Santander also offers the option to start the new rate immediately, waiving any early repayment charges. If you take the early start option, the deal is final and cannot be reversed.
What happens if I have multiple loan parts on my Santander mortgage?
If your mortgage has more than one loan part, the product transfer rules are slightly more complex. Once you have accepted a new deal on one part, no further changes can be made to the other parts until that new deal starts, unless you cancel the pending deal first. If your loan parts have deal end dates within four to five months of each other, it is worth thinking carefully about the order in which you proceed. We can walk through this with you to make sure nothing is locked in at the wrong time.
Can I make an overpayment alongside a Santander product transfer?
If you want to make a lump sum overpayment and do a product transfer at the same time, the overpayment must be made before the product transfer is submitted. Santander has a specific process for this involving a request form, and it must be completed and confirmed before we proceed with the rate switch. If you want to do this, mention it when you speak to us and we will explain the steps.
I have Santander's consent to let on my property, can I still do a product transfer?
Yes, but not through the standard residential product transfer route. If Santander has granted you consent to let your property, you will need to switch using their buy-to-let product transfer range instead. The rates and available deals will differ from the residential options. If this applies to you, mention it when you get in touch and we will make sure we are looking at the right products for your situation.
