What Is a Product Transfer?
A product transfer — sometimes called a rate switch or retention deal — means moving to a new mortgage rate with your existing lender without going through a full remortgage process. Your mortgage stays with the same provider, and the amount you owe does not change. Only the rate and deal terms are updated.
Here is how a product transfer typically works:
- Your lender contacts you: Most lenders write to you a few months before your current deal ends, offering a selection of new rates to switch to.
- You choose a new product: You select from the available options — typically a range of fixed rates, tracker rates, or discount rates at various terms.
- Minimal checks: In most cases, a product transfer does not require a new affordability assessment, credit check, or property valuation. Because you are not borrowing more money or changing lender, the process is streamlined.
- Quick completion: Product transfers can often be completed within a few days, and the new rate usually starts on the day your existing deal ends.
What a product transfer does not allow:
- You cannot borrow additional money (for that, you would need a further advance or remortgage).
- You cannot change lender.
- You generally cannot make significant changes to the mortgage structure (such as switching from interest-only to repayment).
- You are limited to the products your existing lender offers, which may not be the most competitive on the market.
Product transfers have become increasingly popular in the UK, with a significant proportion of homeowners choosing this route when their deal ends. The simplicity and speed are the main attractions, particularly for borrowers who are happy with their existing lender and do not need to raise additional funds.
What Is a Full Remortgage?
A full remortgage involves switching your entire mortgage to a new deal with a different lender. The new lender pays off your existing mortgage, and you start a new agreement with new terms, a new rate, and potentially a different loan amount if you are raising additional capital.
The remortgage process involves:
- Application: You apply to the new lender, providing full details of your income, outgoings, property, and existing mortgage.
- Affordability assessment: The new lender carries out a thorough affordability check, including a review of your income, credit history, and existing commitments.
- Property valuation: The new lender arranges a valuation of your property to confirm its current market value and the available equity.
- Legal work: A solicitor handles the legal transfer, paying off your old mortgage and registering the new lender's charge on your property.
- Completion: Once everything is in place, your old mortgage is redeemed and the new one begins.
Key benefits of a full remortgage:
- Access to the entire mortgage market, not just one lender's products.
- Ability to borrow additional funds by increasing the mortgage amount.
- Opportunity to change the mortgage structure, term, or repayment type.
- Competitive deals from lenders keen to attract new customers, including cashback offers and free legal work.
Key drawbacks:
- More paperwork and a longer process compared with a product transfer.
- Requires a full affordability assessment and credit check.
- Valuation and legal costs may apply (though many deals include these).
- If your circumstances have changed, you may not qualify for the best rates.
Side-by-Side Comparison
Here is a direct comparison of the two options across the factors that matter most to UK homeowners:
| Factor | Product Transfer | Full Remortgage |
|---|---|---|
| Lender | Same lender | New lender |
| Rate options | Limited to one lender | Whole of market |
| Affordability checks | Usually not required | Full assessment required |
| Credit check | Usually not required | Required |
| Valuation | Usually not required | Usually required |
| Legal work | Not required | Required (often free) |
| Speed | Days | 4-8 weeks |
| Additional borrowing | Not possible | Yes |
| Change mortgage structure | Limited | Yes |
| Fees | Product fee may apply | Product fee, valuation, legal |
The table highlights the fundamental trade-off: product transfers are simpler and faster, but remortgaging gives you access to the full market and the ability to make more substantial changes to your mortgage.
For many homeowners, the question comes down to whether the potential rate savings from remortgaging justify the additional time, paperwork, and scrutiny involved. In some cases, the difference in rate is negligible, and a product transfer is the practical choice. In others, remortgaging to a significantly better rate can save thousands of pounds over the deal period.
