Santander UK updated promotional footnotes on its All in One credit card this week after the Financial Conduct Authority’s Consumer Duty sweep found balance-transfer examples that buried the 3% fee and 23.9% variable APR that kick in once the 15-month interest-free window ends.
Claire Whitfield writes: the changes are subtle on the marketing page but meaningful for households juggling Christmas spending and lingering post-festive debt. Santander’s product still offers 0% on purchases and balance transfers for 15 months with no transfer fee during the intro period — a competitive package — but the FCA wanted clearer sequencing about what happens on month sixteen.
What changed on the page
The bank added a shaded callout explaining that new balance transfers after the promotional period attract a 3% charge with a £5 minimum, and that standard purchase and transfer rates apply to any balance left when the intro ends. A worked example now shows a £2,400 transfer and the pound cost if only minimum payments are made — a format the FCA has pushed across the market since Consumer Duty went live.
Santander did not change the £3 monthly card fee or the 0.5% cashback cap. Foreign purchase fees remain waived, though cash withdrawals abroad still trigger immediate interest at 29.9% APR, a detail the refreshed footnotes highlight in bold.
Why the FCA cared
Supervisors have been crawling issuer sites for “teaser rate” friction. In September the authority published aggregated findings showing that nearly one in five balance-transfer pages required consumers to open PDFs to see revert rates. Santander was not named in that release, but firms received individual feedback letters over the summer.
Consumer groups welcomed the tweak. Which? said clearer revert-rate maths is more valuable than another headline-grabbing 0% extension. Debt charities cautioned that even perfect disclosure cannot fix affordability if households stack transfers across multiple issuers.
Competitive context
Barclaycard and Halifax shortened their longest 0% balance-transfer windows earlier this week as funding costs rose, a move this desk covered Wednesday. Santander’s decision to keep 15 months but clarify footnotes suggests a different strategy: hold the headline window, reduce conduct risk.
Monzo and Starling, which compete on app clarity rather than long promo rates, said they continue to see inbound switches from customers confused by revert clauses on legacy cards. That migration is hard to quantify, but credit reference data show Santander’s All in One remains among the top ten UK cards by open accounts.
Practical tips for cardholders
If you opened an All in One before the footnote refresh, your contractual terms are unchanged — only marketing copy moved. Still, it is worth diarising the promo end date and checking whether you can clear the balance before standard interest applies.
Money transfer facilities, sometimes confused with balance transfers, are not a feature of this product; Santander’s site now states that explicitly after the FCA flagged cross-product jargon. For sterling payments to third parties, current-account Faster Payments rules apply, not credit-card money-transfer promotions offered by some rivals.
What issuers do next
Industry lobby UK Finance expects more footnote revisions before the November shopping peak. The FCA has warned it will escalate to formal requirements if firms treat Consumer Duty as a cosmetic exercise. For Santander customers, the lesson is simpler: the longest 0% window only helps if you know exactly when it ends.
