Your home may be repossessed if you do not keep up repayments on your mortgage. Both product transfers and remortgages are regulated activities - ensure any adviser you use is FCA-authorised.
Quick answer
A product transfer stays with your current lender - fast, low-cost, and with minimal paperwork. A remortgage switches to a new lender - potentially better rates, but more process, more cost, and full underwriting. For most borrowers whose circumstances have not changed significantly, the question is simply: does the rate saving from switching lenders outweigh the additional costs and hassle? Sometimes it does, sometimes a competitive product transfer wins. You should compare both with real numbers.

Side-by-Side Comparison
| Factor | Product Transfer | Full Remortgage |
|---|---|---|
| Lender | Same lender | New lender |
| Speed | Days to weeks | 4-8 weeks typically |
| Legal work required | No | Yes (conveyancer) |
| Valuation required | Usually no | Usually yes |
| Full credit assessment | Limited | Full underwriting |
| Rate choice | Current lender's range only | Whole market access |
| Can borrow more? | Not usually | Yes (equity release) |
| Cost | Lower (fewer fees) | Higher (arrangement, legal) |
When a Product Transfer Wins
- Your lender's product transfer rate is competitive with the market
- Your circumstances have changed (income reduction, credit blips) making a new lender's full assessment risky
- Speed is a priority
- The difference between the best transfer rate and best market rate is small relative to switching costs
When Remortgaging to a New Lender Wins
- A materially lower rate is available on the open market versus your transfer deal
- You want to release equity for home improvements, consolidation, or other purposes
- You want to change the mortgage term or add/remove a borrower
- Your LTV has improved significantly and a new lender recognises this better in their pricing
Using a Broker to Compare Both
A whole-of-market mortgage broker can access both the open market and - in many cases - your existing lender's product transfer range simultaneously, making a proper like-for-like comparison straightforward. This is the most efficient way to ensure you are making the optimal decision.
Frequently Asked Questions
A product transfer (sometimes called a rate switch or internal remortgage) means switching to a new mortgage deal with your existing lender. Because you are staying with the same lender and the property charge stays in place, there is no need for a new valuation, conveyancing, or full underwriting assessment in most cases. It is typically quicker and cheaper to arrange than a full remortgage to a different lender.
Not necessarily. Your existing lender's product transfer range may not be competitive with the rates available on the open market. If the gap between the best transfer rate and the best remortgage rate is significant, the additional cost of switching lenders (legal fees, arrangement fees) may be more than offset by the rate saving. Always compare both options with actual savings figures before deciding.
Most lenders carry out a limited credit check when processing a product transfer, though it is typically less intensive than a full mortgage underwriting assessment. You are usually assessed on payment history with the existing lender rather than a full affordability re-evaluation. This makes product transfers more accessible for borrowers whose circumstances have changed since the original mortgage was arranged.
Some lenders allow the term to be adjusted as part of a product transfer; others do not. If you want to extend or shorten your remaining term significantly, or add or remove borrowers from the mortgage, a full remortgage to a new lender may be required - or at least a more detailed application process with the existing lender.
Most lenders allow product transfers to be booked 3 to 6 months in advance, with completion timed for the end of the current deal. This allows you to lock in a rate without triggering early repayment charges, which is particularly useful if you are concerned about rates rising before your current deal ends. Check your specific lender's advance booking policy.
