The Financial Ombudsman Service (FOS) is the United Kingdom’s statutory independent alternative dispute resolution body for complaints by eligible complainants against authorised financial services firms, established under the Financial Services and Markets Act 2000.
Category: Dispute resolution Also known as: FOS, Ombudsman Service, Financial Ombudsman Related concepts: FOS jurisdiction, FOS award limit, FOS time limits, Insurance ombudsman
The Financial Ombudsman Service is the statutory ADR scheme that resolves complaints between eligible complainants (consumers, micro-enterprises, certain small businesses, charities and trusts) and authorised firms regulated by the Financial Conduct Authority and the Prudential Regulation Authority. The FOS’s decisions are binding on the firm if accepted by the complainant; the complainant may reject the decision and pursue litigation instead.
The FOS was established to consolidate eight predecessor ADR schemes, including the Insurance Ombudsman Bureau (1981-2001), the Personal Investment Authority Ombudsman, the Banking Ombudsman, the Building Societies Ombudsman, the Investment Ombudsman, the SFA Complaints Bureau, the PIA Bureau and the FSA Direct Regulation Unit. The single-scheme model commenced operations on 1 December 2001.
The Service determines complaints by reference to what is, in the Ombudsman’s opinion, “fair and reasonable in all the circumstances of the case”, taking into account the relevant law, regulators’ rules, guidance, codes of practice and good industry practice. This standard, set out in DISP 3.6.4R, is broader than strict legal entitlement and is central to the FOS’s distinctive character.
The FOS is established by the Financial Services and Markets Act 2000, Part XVI and Schedule 17. Part XVI confers on the scheme the function of providing for proportionate, prompt and informal resolution of disputes. Schedule 17 deals with the governance of the scheme operator (the Financial Ombudsman Service Limited), funding (firm levies and case fees), and the relationship with the FCA.
Operational rules are in the FCA Handbook, Dispute Resolution: Complaints (DISP). DISP 1 sets firms’ obligations on handling complaints internally. DISP 2 defines the FOS’s jurisdiction (compulsory and voluntary). DISP 3 sets out the FOS’s complaint-handling procedures and the binding effect of decisions. DISP 4 deals with the Voluntary Jurisdiction (VJ).
The FCA, in concurrence with HM Treasury, sets the maximum monetary award limit by statutory instrument and Handbook rule. The current limits are £430,000 for complaints referred on or after 1 April 2024 in respect of acts or omissions from 1 April 2019, and £190,000 for complaints referred in respect of acts or omissions before 1 April 2019. The limits are subject to annual indexation.
The FOS’s procedures are inquisitorial rather than adversarial. The Ombudsman is not bound by the rules of evidence and may take into account material that would not be admissible in court. Judicial review of FOS decisions is available on conventional public-law grounds, but the courts have repeatedly emphasised the wide discretion enjoyed by the Ombudsman (see R (IFG Financial Services) v Financial Ombudsman Service [2005] EWHC 1153 (Admin) and R (Heather Moor & Edgecomb) v Financial Ombudsman Service [2008] EWCA Civ 642).
Complaint handling begins with the firm itself. Under DISP 1.6, the firm has up to eight weeks to issue a final response. If the firm fails to respond in time, or the consumer is dissatisfied with the response, the complainant may refer the matter to the FOS within six months of the final response.
On referral, the FOS first establishes jurisdiction (eligibility, time limits and scope). If the complaint is within jurisdiction, an Investigator gathers evidence and reaches a provisional assessment, which is shared with both parties. Either party may accept or contest the assessment. If contested, the matter is referred to an Ombudsman for a final decision.
The Ombudsman’s final decision is binding on the firm if the complainant accepts it within the deadline (usually one month). Acceptance produces a binding agreement; rejection leaves the parties to litigate the underlying dispute, although as a matter of practice this is uncommon. The Ombudsman may direct payment of compensation up to the award limit, award interest at a specified rate (commonly 8% simple per annum), and recommend (but not direct) payment in excess of the limit.
Firms fund the FOS through a combination of an annual levy (allocated by industry block) and case fees per chargeable case. Most firms receive a small number of “free” cases per year before case fees apply. Funding arrangements are reviewed periodically.
The FOS publishes anonymised decisions on its website, generating a substantial body of indicative jurisprudence on common dispute categories. While decisions are not precedent in the legal sense, they provide important guidance on the Ombudsman’s likely approach.
Compulsory Jurisdiction (CJ): All FCA-authorised firms must accept the FOS’s jurisdiction for complaints by eligible complainants relating to regulated activities. CJ is mandatory and cannot be excluded by contract.
Voluntary Jurisdiction (VJ): Firms may join the VJ to extend FOS coverage to activities outside the CJ. VJ firms agree to be bound by the FOS in respect of the additional scope.
Eligible complainant categories: Consumers (private individuals), micro-enterprises (turnover under €2 million and fewer than 10 employees), small businesses (turnover under £6.5 million, balance sheet under £5 million, fewer than 50 employees), charities with annual income under £6.5 million, trustees of trusts with net assets under £5 million, and certain consumer buy-to-let landlords. The exact thresholds are in DISP 2.7.
Single Decision-Maker vs Ombudsman panel: Most cases are determined by a single Ombudsman. Particularly complex or precedent-setting cases may be referred to a panel.
Distinguish from CMA, ICO and CASS: The FOS handles complaints; the Competition and Markets Authority addresses market issues; the Information Commissioner’s Office handles data protection; and the Client Assets Sourcebook (CASS) regime governs the protection of client money rather than complaint resolution.
A consumer holds a buildings insurance policy with an FCA-authorised insurer. Following storm damage, the insurer offers settlement at £8,000, well below the £25,000 estimate from the consumer’s surveyor. The consumer complains; the insurer issues a final response upholding its valuation. The consumer refers the matter to the FOS within six months, attaching the surveyor’s report.
The FOS Investigator obtains the insurer’s loss-adjusting report, the policy schedule and the surveyor’s evidence. The Investigator provisionally finds in the consumer’s favour to the extent of £18,000, citing the insurer’s failure to instruct a surveyor with the relevant specialism and an undisclosed adjustment for “betterment” that did not align with the policy wording. The insurer contests the assessment. The matter is referred to an Ombudsman, who issues a final decision in favour of the consumer at £19,500 plus interest at 8% from the date of declinature. The consumer accepts; the insurer is bound, and payment is made within four weeks.
