Asda Admits Underpaying 53,000 Staff Due to Failed £1B IT Upgrade, Promises Full Repayment With 12% Interest

Asda admits 53,000 employees were underpaid between February 2024 and May 2025 due to errors in holiday and sick pay calculations following its botched “Project Future” IT overhaul. The supermarket will repay all owed amounts plus 12% interest, including clawed-back overpayments from March 2024. Executive Chairman Allan Leighton confirmed 33,000 affected workers remain employed; over 80% are owed less than £19. The £1 billion system migration—delayed from February to September 2025—triggered operational chaos, including payroll failures and a 2.8% sales drop in Q3 2025. Leighton blamed poor integration and testing, admitting the project set Asda’s turnaround back by six months. External experts have since validated corrective measures.
