Fraud cases in the UK reached an unprecedented high in the first half of 2026, with over 220,000 incidents filed with the National Fraud Database (NFD) between January and June. This represents the highest volume ever recorded for a six-month period, according to Cifas, the non-profit organization that manages the NFD and the Insider Threat Database.
Identity fraud was a significant contributor to this surge, increasing by 9% year-on-year to nearly 130,000 cases. Scammers primarily targeted bank accounts and plastic cards, which together accounted for 68% of these identity fraud incidents. Impersonation incidents where a victim's real address was used also saw a 12% year-on-year rise. While "false identity" filings decreased by 35% in the banking and telecoms sectors, Cifas noted ongoing concerns regarding synthetic identities, AI-enabled impersonation, and digitally manipulated documents.
Account takeover cases also drove the increase in fraud, with nearly 40,000 incidents recorded, a 5% year-on-year rise. Within this category, online retail incidents jumped by 84% and card account incidents by 59%. Unauthorized SIM-swap cases experienced a dramatic 402% increase, reaching 4,109 incidents and now constituting 10% of all filings, up from 2% a year prior.
Young adults are increasingly involved in fraud, both as victims and perpetrators. Although victims aged 61 and over still represent the largest demographic for identity fraud, the 21-30 age group saw the most significant increase, with cases rising by almost a third (32%). Concurrently, individuals under 30 accounted for a majority (57%) of money muling cases, with 17% of these being under 21.
Cases linked to money muling surged by 69% annually in the first half of 2026, with over 13,000 filings in the NFD. This activity now makes up 30% of all "misuse of facility" cases, which involve the genuine account holder misusing an account or product. Part of this increase is attributed to improved detection methods and the introduction of a new filing reason, "funds received – money muling," in 2025.
Cifas CEO Mike Haley emphasized that identity fraud now accounts for three-fifths of all cases in the NFD, underscoring the value of personal information to criminals. He stated that stolen personal data frequently serves as the initial entry point for various criminal activities, including opening new accounts, taking over existing facilities, or supporting broader illicit operations. Haley also highlighted the critical importance of early intervention, education, awareness, and prevention, particularly for younger individuals who are increasingly vulnerable to fraud risks as criminals adapt their tactics and leverage digital channels.
