NatWest Group extended the promotional 0% balance-transfer period on its Reward credit card to 28 months for new applicants, revising app copy and branch leaflets after the Financial Conduct Authority flagged concerns that representative APRs were not prominent enough once introductory offers end. The change is commercially small for a bank the size of NatWest, but it is exactly the sort of product tweak Claire Whitfield’s desk tracks because it alters the monthly bill for households consolidating expensive store-card debt before Christmas.

The FCA did not announce enforcement action. Instead, supervisors referenced Consumer Credit sourcebook rules requiring promotions to be clear, fair, and not misleading, particularly where a comparison table highlights the zero-rate window without an equally visible revert rate. NatWest said it proactively adjusted screens so the standard variable APR—currently north of 24% for many applicants—appears before customers confirm a transfer limit.

Pounds on the statement

Balance-transfer cards earn money two ways: upfront fees, typically a few percent of the moved balance, and interest after the promo expires. On a £3,000 transfer with a 3.15% fee, the customer pays £94.50 on day one but saves roughly £45 a month compared with carrying the same debt on a 20% store card, assuming minimum payments. Stretching the zero window from 24 to 28 months pushes the break-even on that fee further out, which helps disciplined payers but rewards procrastinators if they forget the cliff edge.

NatWest’s Reward variant still pays cashback on supermarket spend, which complicates mental accounting: households may leave purchases on the card while attacking transferred balances, a behaviour regulators worry about when promotions blur purchase and transfer APRs. The bank now separates those balances in app statements with colour coding compliance teams signed off last week.

FCA promo review in context

The watchdog has been scrutinising credit-card marketing since the cost-of-living pressure intensified, focusing on whether digital journeys bury risk warnings below fold on mobile. Handbook section CONC 3.5 requires representative examples when incentives are advertised; NatWest’s earlier creative passed legal review but failed a mystery-shopping pass where testers scrolled only on marketing tiles. Peer banks including Barclays and Santander have similar 30-plus-month offers, so regulators are comparing fee structures and revert-rate disclosure side by side.

For customers who miss a payment, UK rules allow promotional rates to vanish immediately. NatWest reiterated that a late direct debit in month one can void the 0% transfer deal—a clause the FCA wants shown in the same font size as the headline months, not in a PDF appendix. Debt charities welcomed the longer window but urged borrowers to set calendar reminders 60 days before expiry.

Who should not apply

Applicants with recent defaults or high utilisation on other NatWest lines may be offered a shorter promo or declined outright. Balance transfers cannot usually move money between cards issued by the same banking group, so existing NatWest cardholders must look elsewhere to shuffle debt. Those planning major purchases should compare purchase APRs: the Reward card’s purchase promo is shorter than its transfer window, a mismatch that trips people who put holidays on plastic while consolidating catalogue debt.

Issuer profitability on these products depends on a minority of revolvers who hit revert rates. Regulators are not banning long promos; they are forcing banks to show the revert path before sign-up. NatWest’s tweak is a template other issuers may copy before the FCA publishes aggregated findings. For households, the actionable detail is the fee plus revert APR on the confirmation screen—not the banner months in the marketing email.

Reward points earned on supermarket spend continue to post after a transfer, but redemption values shift with partner offers; customers consolidating debt should not chase cashback if it encourages fresh spending on the same plastic. Setting a separate direct debit for the transfer balance alone remains the simplest way to hit zero before month 28.
