Product transfer vs remortgage: which should you choose?

A product transfer is a new deal with your current lender: fast, no legal work, no affordability check. A remortgage moves you to a different lender, which can be cheaper but means an application, a valuation and conveyancing. The right choice is whichever leaves you paying less once the hassle is priced in.

What each one actually is

When your fixed rate ends you roll onto the lender's standard variable rate, which is usually expensive, so most people switch to a new deal. There are two ways to do it. A product transfer swaps you onto a fresh rate with the same lender, keeping the same loan and the same account. A remortgage pays off your existing lender with a loan from a new one.

The mechanics differ sharply. A product transfer needs no new affordability assessment, no property valuation and no solicitor, so it can complete in days and often costs nothing to arrange. A remortgage is a full application: income checks, a valuation, legal work to move the charge from one lender to another, and sometimes fees for all three. See what happens when your fixed rate ends for the six-month run-up that applies to both.

When the product transfer wins

Stay put when moving lenders would fail or cost more than it saves. The transfer is the safer pick if your circumstances have worsened since you took the mortgage: a drop in income, a switch to self-employment, a new dependant or a hit to your credit file. Because there is no affordability check, a product transfer sidesteps all of that, so people who might now be declined elsewhere keep access to competitive rates.

It also wins on small balances. On a £90,000 remaining loan, a remortgage that is 0.2% cheaper saves about £180 a year, which £1,000 of fees and a fortnight of admin can easily wipe out. When the balance is modest, the rate gap has to be large before switching pays.

When the remortgage wins

Move lenders when the sum is worth it and you qualify. On a £250,000 balance over 25 years, a rate of 4.3% instead of 4.6% cuts the monthly payment by roughly £40, about £480 a year, so even with £1,000 of costs you are ahead inside three years. Many remortgage deals also come with free valuation and free legals, which shrinks the gap further.

A remortgage is also the route if you want to change the loan itself, not just the rate: borrowing more for home improvements, shortening the term, or moving from interest-only to repayment. A product transfer can usually only re-rate the loan you already have. Put your balance, rate and term through the mortgage repayment calculator to see the monthly difference before you commit.

How to decide in practice

Get your current lender's product transfer offer first, since it costs nothing and takes minutes, then treat it as the number to beat. Compare it against the best remortgage deal you would actually qualify for, and include every cost on the remortgage side: arrangement fee, valuation, legal fees and any exit fee. If the remortgage saves more than those costs over the fixed period, switch; if not, or if a fresh affordability check is risky for you, take the transfer. Start the comparison around six months before your current deal ends so you have time to complete either way.

Common questions

Is a product transfer cheaper than a remortgage?

Often it is cheaper to arrange, because a product transfer usually has no valuation, legal or affordability costs and can complete in days. But a remortgage to a lower rate can save more overall on a large balance. On £250,000, a 0.3% lower rate saves about £480 a year, enough to cover typical switching fees within three years.

Does a product transfer need an affordability check?

No. Staying with your current lender on a product transfer means no new affordability assessment and no valuation, so it is the safer option if your income has dropped, you have gone self-employed, or your credit has taken a knock. A remortgage to a new lender does require a full check.

Can I borrow more with a product transfer?

Usually not much. A product transfer mainly re-rates the loan you already have. If you want to raise money for an extension, shorten the term, or change the loan type, that generally needs a remortgage or a separate further advance, both of which involve an affordability check.

When should I start looking at a product transfer or remortgage?

About six months before your current deal ends. Rate offers can usually be secured that far ahead and held, so you can lock in early and still switch if something better appears. Leaving it late risks slipping onto the standard variable rate, which is typically far more expensive.
