The UK-specific breakdown on high risk merchant accounts. The page explains what factors push businesses into high-risk classification in the UK and EEA context — including industry type, subscription billing models, high average transaction values, international card-not-present transactions, and chargeback history. The coverage of Visa and Mastercard’s formal monitoring programme thresholds, and how breaching them leads to penalties and terminations, is particularly clear and actionable. Relevant for anyone evaluating high risk merchant account providers or comparing high risk merchant service providers in 2026.
