Returns fraud is becoming an expensive problem for UK eCommerce retailers. Research published by Cifas and the University of Portsmouth in May 2026 estimates that refund fraud could be costing UK online retailers up to £5.76 billion annually. From false non-delivery claims to returning used or substituted products, fraudulent returns create financial losses and put pressure on fulfilment operations.
With billions of pounds of online purchases returned every year, identifying suspicious behaviour without delaying genuine refunds is increasingly important. Better returns data, earlier product assessment and automated decision-making rules can help retailers manage risk while protecting customer experience.
