Card transaction duplications

Ongoing since 09:19 PM UTC, affecting Credit Card Services.

identified Nov 11, 2026, 09:19 PM UTC

Due to a technical issue, a small number of credit and debit card transactions processed on Wednesday 11 November have been duplicated. We believe this was a global issue impacting our card provider that has since been contained. We’re currently working to reverse the duplicated payments. If you have noticed a duplication in your account, please do not attempt to correct this yourself - our tech teams will apply a fix and make sure no-one is out of pocket. If this issue is causing you immediate financial hardship, please call us on 0800 400 600. Thank you for your patience while we resolve this and we apologise for the inconvenience.
