SKN | Santander Ordered to Refund Gambling Losses After Ombudsman Finds Account Restrictions Were Inadequate

Key Takeaways:

• Santander was ordered to refund a customer’s gambling losses incurred after he disclosed gambling addiction and requested assistance with restricting transactions.
• The Financial Ombudsman Service found that the bank had not adequately applied restrictions across the customer’s accounts, allowing gambling-related payments to continue for several weeks.
• The ruling includes repayment of eligible losses, 8% interest and £500 in compensation, highlighting the importance of effective safeguards for financially vulnerable customers.

Santander has been ordered to reimburse a customer who lost a substantial portion of his house-sale proceeds through gambling after notifying the bank of his addiction and requesting assistance. The Financial Ombudsman Service (FOS) determined that Santander did not implement effective restrictions across the customer’s accounts quickly enough, allowing further gambling transactions to take place. The decision places renewed attention on how banks identify financial vulnerability and respond when customers explicitly request protection from harmful spending.

Santander’s Response Failed to Restrict All Payment Channels

The customer, identified only as Mr R, received approximately £25,000 from a property sale on July 18, 2025. Within a month, he had spent around £16,000 gambling. On August 15, 2025, he contacted Santander and disclosed his gambling addiction, alongside the financial and mental health difficulties associated with compulsive spending.

Although the bank blocked online transactions from his main account six days after the initial contact, the restriction did not cover his top-up card account. Mr R was therefore able to continue transferring money and making payments to an overseas casino. Santander did not impose restrictions on that additional account until October 1, 2025, approximately six weeks after the initial online block.

Financial Ombudsman Highlights the Bank’s Responsibility

In its written decision, the FOS concluded that Santander should have made clear that an online gambling block was necessary to prevent the transactions taking place. The ombudsman also found that the bank had the ability to apply the appropriate restrictions on the customer’s behalf, rather than leaving the responsibility entirely with him.

Santander argued that Mr R was responsible for activating the necessary gambling blocks. However, the ombudsman rejected that position in light of the customer’s explicit disclosure of financial harm and mental health difficulties. The decision also noted that the evidence showed no further gambling after the correct restrictions were eventually applied.

Refund and Compensation Reflect the Consequences of Delayed Action

The FOS ordered Santander to refund the gambling losses incurred between the customer’s first notification of his addiction on August 15, 2025, and September 17, 2025, when he referred the complaint to the ombudsman. The repayment must include 8% interest, alongside £500 in compensation.

The ruling is also relevant to the Financial Conduct Authority’s Consumer Duty framework, which requires firms to take particular care when dealing with vulnerable customers. FCA guidance identifies gambling-blocking facilities as an example of good practice. In this case, the central issue was not simply whether Santander offered account restrictions, but whether those controls were sufficiently comprehensive and effective once the customer requested help.

Why Santander’s Case Matters for Banking Risk Management

For Santander, the decision illustrates the operational and reputational risks associated with fragmented account controls and inadequate responses to vulnerability disclosures. Customers may hold multiple payment products within the same banking relationship, making consistent restrictions important when financial harm has been explicitly identified.

For international banking clients, the broader lesson is that customer-protection policies must function across relevant payment channels, not merely exist as optional account features. Going forward, the effectiveness of Santander’s vulnerability procedures, escalation processes and account-level safeguards will remain important measures of its consumer-protection standards.
