UK Financial Ombudsman Service Business Response

Reference guide. Last verified 2026-07-07. Sources cited below.

The situation

James, 58, is a sole-practitioner independent financial adviser (IFA) in Bristol, authorised by the FCA. He has 280 clients, primarily retirees. In April 2026 he received a FOS complaint reference: a former client is claiming £18,000, alleging that a pension transfer recommendation made in 2022 was unsuitable.

James has 15 working days to file his business response with FOS.

James sends a 3-page letter explaining what he discussed with the client, why he thought the transfer was suitable, and that the client was fully informed. The FOS adjudicator finds against James and recommends he pay the full £18,000, noting that his response "did not address the suitability assessment requirements of COBS 9.2 or provide documentation demonstrating the client's attitude to risk was properly captured."

James didn't know: FOS adjudicators are looking for a specific structure, regulatory mapping (which FCA rules applied), process evidence (how the suitability assessment was conducted step-by-step), and causation analysis (would a compliant process have reached the same outcome). His narrative letter described events but didn't speak the adjudicator's language.

A specialist compliance consultant could have structured his FOS response for £2,500. A self-serve tool that knows what adjudicators look for would have cost £79.

Who receives this

Small UK FCA-authorised firms receiving FOS complaint referrals, sole-practitioner IFAs, small mortgage brokers, small insurance intermediaries, small credit brokers, and small payment service providers. Primary: IFAs and mortgage brokers (the two largest sources of FOS complaints among small firms). Secondary: small consumer credit firms, insurance intermediaries.

Why the agency will not advise you

FOS case handlers adjudicate between parties, they cannot advise the business on how to structure its response. The FCA's DISP rules and Consumer Duty framework are complex regulatory documents that small firms cannot navigate without specialist help. No self-serve tool exists for the business (respondent) side of FOS complaints.

Key facts, with sources

  • The Financial Ombudsman Service received 198,798 new complaints in the financial year 2024-25, an all-time record. The FOS handles complaints across banking, insurance, investments, mortgages, and consumer credit. When a consumer complaint is referred to FOS after the firm has issued a Final Response Letter (or 8 weeks have passed without resolution), the FOS sends a formal complaint reference to the regulated firm and requests its business response within 15 working days. FOS adjudicators consider both the consumer's account and the firm's response; they cannot advise the firm on how to structure its response. The July 2025 HM Treasury consultation on FOS reform noted that small firms are systematically disadvantaged in the FOS process due to lack of expertise in structuring business responses.

  • The FCA's Dispute Resolution (DISP) sourcebook governs how regulated firms must handle complaints and engage with FOS. DISP 1 requires firms to have effective complaint handling procedures; DISP 2 covers FOS jurisdiction; DISP 3 covers the ombudsman's approach to determining complaints. FOS applies the 'fair and reasonable' test, considering what is fair and reasonable in all the circumstances, including relevant law, regulation, regulatory guidance, and good industry practice. Since July 2023, the Consumer Duty (FCA PS22/9) adds an additional 'consumer outcomes' dimension to FOS assessments: the ombudsman now explicitly considers whether a firm's conduct met its Consumer Duty obligations. Small firms, IFAs, mortgage brokers, insurance intermediaries, often submit FOS business responses that describe facts but fail to map those facts to DISP/Consumer Duty obligations, resulting in avoidable adverse adjudications.

When to bring in a professional

Self-serve responses fit routine cases: clear facts, amounts a business can absorb, and a deadline still ahead of you. Bring in a licensed professional when the amount at stake is large relative to their fee, the facts are genuinely disputed, criminal exposure is possible, or the deadline has already passed. A short paid consultation to sanity-check your plan is often worth it even when you handle the filing yourself.
