The PSR mandatory reimbursement rules cover microenterprises — businesses with fewer than 10 employees and annual turnover or balance sheet below £1.7 million. Small charities with annual income under £1 million are also covered.
For qualifying businesses, the same rules apply: the bank must reimburse up to £85,000 within 5 business days, with FOS escalation available for amounts up to £430,000.
Larger businesses are not covered by PSR mandatory reimbursement, but may have other legal routes including breach of duty of care, FCA Consumer Duty obligations, and potential unjust enrichment claims against receiving banks.
