Product Transfer vs Remortgage: Which Is Right for You?

Last reviewed and updated by Darren Shepherd: September 2026

When your mortgage deal comes to an end, a lot of people assume there is nothing to think about: the lender sends a new rate, you tap accept, job done. The trouble is that the rate your lender offers you is only ever their rate. The other option, moving to a different lender, often beats it, sometimes by thousands of pounds over the deal. Knowing the difference between a product transfer and a remortgage is how you avoid leaving money on the table.

The two options in plain English

When your fixed or tracker deal ends, you have two real choices, plus the one you never want, which is drifting onto the Standard Variable Rate.

• Product transfer. You stay with your current lender and switch onto one of their new deals. Same lender, same loan, new rate.
• Remortgage. You move to a different lender. They pay off your existing mortgage and you start a fresh deal with them.

Both get you off the expensive SVR and onto a competitive rate. The difference is in how much work is involved, and how good the rate you end up with is.

What a product transfer actually is

A product transfer is the quick, low-friction option. Because you are staying put, the lender already knows you, so in most cases there is no new affordability assessment, no property valuation, and no solicitor. It can often be done online or over the phone, and the new rate starts the day your old one ends.

The catch is simple: you only ever see one lender's shelf. Your existing lender offers you their deals, and they have no particular reason to make them their sharpest. You cannot tell whether it is good value without comparing it to everyone else.

What a remortgage actually is

A remortgage is a full new mortgage application, just with a different lender. That means the lot: proof of income, bank statements, a credit check, an affordability assessment, a valuation of your home, and legal work to move the charge from one lender to another.

It is more involved and takes longer, usually four to eight weeks. In return, you get the whole market to choose from, which is where the better rates tend to live, and new-lender perks like free legals or cashback often cover much of the cost of switching.

Side by side

• Speed: product transfer in days, remortgage in weeks.
• Paperwork: product transfer almost none, remortgage a full application.
• Affordability and credit checks: usually skipped on a transfer, always done on a remortgage.
• Valuation and legals: usually none on a transfer, both on a remortgage, and often free.
• Choice: one lender on a transfer, the whole market on a remortgage.
• How early you can lock in: a remortgage offer usually lasts around six months, so you can secure a rate about six months before your deal ends; most lenders only open the product transfer window three to four months out.
• Best for: a transfer for speed or changed circumstances, a remortgage for the best rate or to change the mortgage.

When a product transfer is the better call

Staying put is sometimes genuinely the smart move, not just the easy one:

• Your circumstances have changed. If your income has dropped, you have recently become self-employed, you have had a credit blip, or you are on maternity leave, a new lender's affordability check might say no. Because a transfer usually skips that check, it can be the only door still open.
• You are short on time. If your deal ends in a few weeks, a transfer can be arranged far quicker than a remortgage, so you avoid even a day on SVR.
• The balance is small. On a low remaining balance, the fees and effort of a remortgage can outweigh a slightly better rate.

When remortgaging usually wins

If your finances are healthy and you have a bit of time, the wider market usually rewards you:

• You want the sharpest rate. Different lenders compete for your business, which is exactly what a transfer does not give you.
• You want to change the mortgage. Borrowing more for home improvements, changing your term, or switching repayment type all suit a remortgage far better than a transfer.
• You have decent equity. More equity opens up the lowest loan-to-value deals, and the savings can dwarf the hassle.

The bit nobody tells you

Your lender's product transfer offer is take it or leave it, and they are banking on you taking it. It is the path of least resistance, which is exactly why it is so profitable for them. The only way to know whether their deal is genuinely good is to hold it up against the rest of the market. Sometimes the transfer wins. Often it does not.

Watch the timing if you still have an early repayment charge

If you are thinking of switching before your current deal officially ends, check for an early repayment charge first. Leaving a few weeks early to dodge SVR can be worth it; leaving a year early and paying a 3% penalty usually is not. Both a transfer and a remortgage can be lined up in advance to start the day your current deal expires.

How far ahead can you lock the rate in?

This is a real difference between the two routes, and one that most comparisons skip. When you remortgage to a new lender, the mortgage offer they issue is normally valid for around six months, so you can apply and secure a rate roughly six months before your current deal ends. A product transfer cannot usually be booked that early. Since 2024 most of the big lenders have cut their transfer windows to three or four months before the end date (Halifax, Nationwide, NatWest, Santander, Virgin Money and Coventry work to four months, Barclays, HSBC and Yorkshire Building Society to 90 days, TSB and Skipton to three), with only the odd one or two, such as Principality for direct customers and the Co-operative Bank, still offering six.

If rates are rising, or you simply want certainty early, that extra couple of months of protection can be valuable. It is also why it makes sense to check remortgage rates at the six-month point even if you expect to end up taking your own lender's deal: you can hold the remortgage offer as insurance, then compare it with the transfer once that window opens. The lender-by-lender windows, and the rules on switching to a cheaper rate after you have booked, are all in my full guide to how product transfers work.

How a broker helps

This is the job a whole-of-market broker is built for: they put your existing lender's product transfer rate side by side with every other lender's remortgage deals and tell you which is genuinely cheaper once the fees are counted. They also handle the application, the paperwork and the chasing. Brokers' fees vary, some charge a fee and some are paid only by the lender, so always ask upfront what you will pay and when. The first conversation costs nothing.

If your deal is ending in the next six months, this is the moment to compare both routes rather than just accepting the rate that lands in your inbox.
