The PSR mandatory reimbursement scheme has no minimum claim value. Even if you lost a few hundred pounds, your bank is required to reimburse you if the payment qualifies.
However, banks may apply a £100 excess on your refund (this doesn’t apply to vulnerable consumers). For very small losses, this excess can be a significant proportion of your claim.
Our professional service has a minimum claim threshold of £1,500, as smaller claims are uneconomic to pursue on a no-win-no-fee basis. For losses below this amount, we recommend contacting your bank directly — the process is straightforward and the Financial Ombudsman is free if your bank refuses.
