Millions of customer complaints are processed every year across the United Kingdom’s financial services industry, making the quality of complaint investigations an increasingly important measure of consumer protection, regulatory compliance and corporate governance.

According to the UK’s Financial Conduct Authority (FCA), financial services firms received more than 2.04 million complaints and paid £558.8 million in customer redress, highlighting the growing importance of ensuring that complaint investigations are thorough, evidence-based and capable of withstanding regulatory scrutiny.

Against this backdrop, financial services professional Babatunde Ogunsipe has highlighted the critical role of complaint quality assurance in strengthening customer trust and improving institutional accountability.

Ogunsipe served as a Complaint Quality Checker with Royal Bank of Scotland through Alexander Mann Solutions, where his responsibilities centred on reviewing completed complaint investigations to ensure they complied with regulatory standards, internal policies and evidence-based decision-making processes.

Rather than investigating complaints directly, his role focused on assessing whether investigations had been conducted fairly, whether available evidence had been properly evaluated and whether the conclusions reached were consistent with both company procedures and regulatory expectations.

Industry observers note that quality assurance has become an increasingly important function within financial institutions as regulators place greater emphasis on fair customer outcomes and transparent complaint handling.

The Financial Ombudsman Service reported receiving 278,033 new complaints during the 2020/21 financial year, with banking and credit-related disputes accounting for more than 170,000 cases. During the same period, the organisation resolved 247,916 complaints, while complaints relating to banking and credit products increased by 66 per cent compared with the previous year.

These figures illustrate the operational pressure facing financial institutions and the growing need for robust internal quality controls capable of identifying weaknesses before complaint decisions are challenged externally.

Speaking on the importance of quality assurance, Ogunsipe said the credibility of any complaint investigation depends on the strength of its evidence and the consistency of its reasoning.

“A complaint review must establish whether the facts were properly examined, whether policy was correctly applied and whether the outcome can be justified by the available evidence,” he said.

“If those elements are weak, the investigation may appear complete on paper but still fail under closer scrutiny.”

He noted that consistency remains one of the biggest challenges in large-scale complaint handling operations, particularly where thousands of similar cases are reviewed across multiple teams.

“The real test is whether similar complaints are assessed to the same standard and supported by the same level of reasoning,” he said.

“That consistency is what gives credibility to the process and confidence in the outcome.”

The FCA requires regulated firms to provide customers with a final response to complaints within eight weeks, placing significant operational demands on complaint-handling teams while maintaining expectations around fairness and regulatory compliance.

Industry experts say quality assurance functions play an important role in helping organisations reduce conduct risk, improve customer outcomes and minimise the likelihood of complaints being overturned by external dispute resolution bodies.

European regulators, including the European Banking Authority and the European Securities and Markets Authority, have also encouraged financial institutions to adopt consistent complaint-handling standards to strengthen consumer confidence and improve governance across the financial sector.

Within large financial institutions, complaint quality reviewers operate between frontline investigators and external regulatory oversight, examining whether investigations are supported by sufficient evidence and whether decisions are capable of withstanding independent review.

According to Ogunsipe, effective complaint handling extends beyond meeting regulatory deadlines.

“Fairness in complaint handling is demonstrated through the strength of the investigative process, the quality of the evidence and the discipline applied in reaching a decision,” he said.

“As financial services become increasingly regulated, maintaining those standards is essential to protecting both customers and the integrity of financial institutions.”

As regulators continue to place greater emphasis on customer treatment, governance and operational resilience, professionals involved in complaint quality assurance are expected to play an increasingly important role in ensuring that complaint investigations remain fair, consistent and evidence-driven.
