UK Consumer Duty, Complaints and Redress: How Accountability Works

A good complaints function is a sensor for the business model. A single case may expose an unclear communication, a broken support journey or a product that delivers poor value to an entire cohort. Treating the payment of compensation as the end of the matter leaves the cause—and the next complaint—in place.

This guide separates prevention, dispute resolution, regulatory remediation and failure compensation. It complements Kurums’ UK regulator map, consumer-credit guide and financial-advice system analysis.

What is the Consumer Duty?

The Consumer Duty is the FCA’s outcomes-focused standard for a firm’s retail-market business. Principle 12 states that a firm must act to deliver good outcomes for retail customers. Detailed rules and guidance in PRIN 2A translate that principle into conduct across design, distribution, communications, support, governance and monitoring. The Duty applies according to activity and customer scope, not simply because a firm is FCA-authorised.

The Duty raises expectations beyond producing compliant documents. A firm should define the outcome a customer should receive, collect evidence, identify differences between cohorts and act when results are poor. Proportionality affects how a small and simple firm implements those tasks; it does not remove the obligation. Products with greater harm potential require more searching evidence and stronger controls.

What are the three cross-cutting obligations?

A firm must act in good faith toward retail customers, avoid causing foreseeable harm, and enable and support customers to pursue their financial objectives. These duties shape how the four outcomes are interpreted. They require more than reacting to an explicit complaint when the firm can reasonably identify a harmful design, process, communication or distribution pattern in advance.

Foreseeable harm is not a promise that every investment succeeds or every borrower avoids difficulty. Customers retain responsibility for decisions, and products can carry understood risk. The firm’s task is to design for the target market, communicate effectively, remove unreasonable friction and respond to evidence. A legitimate risk disclosed clearly is different from a preventable harm created by the firm’s choices.

How do the four outcomes work?

The products-and-services outcome concerns target markets, design, approval, distribution and regular review. Price and value asks whether the total benefits are reasonable relative to the total price and foreseeable limitations. Consumer understanding requires communications that help customers make informed decisions. Consumer support requires service that lets customers use, change, claim, complain about or exit a product without unreasonable barriers.

The outcomes interact. A well-designed product can fail if customers misunderstand exclusions; a clear communication cannot rescue poor value; a fairly priced policy delivers little if claims support is inaccessible. Firms should avoid four separate compliance workstreams that never meet. A customer journey and product-level dashboard can show how design, price, understanding and support combine in actual results.

When did the Duty take effect and is it retrospective?

The Duty applied from 31 July 2023 to new and existing products open for sale or renewal. It applied from 31 July 2024 to closed products—broadly, contracts taken before the first deadline that were no longer marketed or distributed after it. Closed books still require support, value and harm analysis even though new target-market distribution may no longer occur.

The FCA states that the Duty is not retrospective: conduct is judged against the standards in force when it occurred. Yet existing contracts are subject to the Duty on a forward-looking basis from the relevant implementation date. A historic product term can therefore create a current support or value issue. Earlier rules, contract law and ombudsman standards may still apply to pre-Duty conduct.

Does a Duty breach give customers a private court action?

FCA Handbook PRIN 3.4 specifies that contravention of the Principles does not itself give a private person a right of action under section 138D FSMA. That includes the Consumer Duty architecture in PRIN. The policy choice does not make the Duty optional or prevent the FCA from supervising and enforcing it.

Customers may have other causes of action under contract, tort, statute or sector-specific rules, and the Ombudsman can consider regulatory standards when deciding what is fair and reasonable. Firms should therefore avoid two opposite errors: presenting the Duty as an automatic damages code, or assuming the absence of a direct PRIN action eliminates complaint, remediation, enforcement and reputational consequences.

What must governing bodies and senior managers do?

At least annually, the governing body must review and approve a report on outcome monitoring, confirm whether the firm complies, assess whether future strategy is consistent with the Duty and agree required actions. The report should enable challenge rather than provide ceremonial assurance. Senior Management Function responsibilities and individual conduct rules support accountability but do not replace collective board oversight.

The FCA’s review of 180 first-year board reports found strong examples built around the four outcomes, good-quality management information, cohort and vulnerability analysis, clear action ownership and culture. Weak reports asserted good outcomes without thresholds, rationale or distribution-chain evidence. An update in February 2026 emphasised that small firms can use proportionate, straightforward governance while still testing outcomes.

Which data show whether outcomes are good?

Useful evidence can include take-up and cancellation, claims or approval rates, arrears, fees, complaints, FOS decisions, call waiting and abandonment, digital drop-off, vulnerability support, communication testing, switching, dormant balances and exceptions. The metric must connect to a defined outcome and have a reasoned threshold; a green status with no customer interpretation is not assurance.

Averages can conceal harm. Firms should compare new and long-standing customers, distribution channels, age or vulnerability groups where lawful and relevant, product variants and customers who attempt to exit or claim. Quantitative data need case reviews and customer research, while qualitative stories need scale. The analysis should identify cause, customer population, severity, duration and whether the remedial action changed results.

How should a firm handle an individual complaint?

A complaint is broadly an expression of dissatisfaction about a financial service or redress determination involving alleged or actual financial loss, material distress or material inconvenience. The firm should recognise substance rather than demand a formal label, record the issue, investigate impartially, preserve evidence and communicate in plain language. Front-line resolution within three business days has specific summary-response requirements.

The investigation should reconstruct what happened, which standards and contract terms applied, whether the customer was treated fairly and what would put matters right. It should address every material point and explain calculations. A final response must tell an eligible complainant about the Financial Ombudsman Service and applicable referral period. Complaint handlers need authority to challenge the business that created the problem.

What are the response and referral time limits?

Most firms have eight weeks to issue a final response or explain the delay and the customer’s Ombudsman rights. Complaints about payment services, electronic money, fraud and scams generally use 15 business days, with a possible final response by 35 business days in exceptional circumstances under the detailed rules. Sector-specific pauses or temporary arrangements can apply, so the product and date matter.

A customer normally needs to complain within six years of the event or, if later, three years from when they knew or reasonably should have known they had cause. After a valid final response, the usual FOS referral window is six months. Exceptional circumstances and specialised regimes can affect admissibility. A firm should state the actual deadline rather than paraphrase it vaguely.

How does the Financial Ombudsman Service decide cases?

FOS is an independent statutory dispute-resolution service, not a court and not the FCA. It considers eligible complaints after the business has had an opportunity to respond. An investigator may propose an outcome; unresolved cases can proceed to an ombudsman’s final decision. The test is what is fair and reasonable in all circumstances, taking account of law, regulation, codes and good practice.

If the complainant accepts a final decision within the stated period, it becomes binding on both sides. If not accepted, court rights are generally preserved, subject to limitation and legal advice. FOS can direct steps and award financial loss, interest, distress or inconvenience within its powers. It is free to consumers and eligible businesses; paid representation is not normally necessary.

Who can complain to FOS and what is the 2026 award limit?

Eligibility includes individual consumers, micro-enterprises and defined small businesses, charities and trusts. A small business generally has turnover below £6.5 million and either balance-sheet assets below £5 million or fewer than 50 employees, subject to detailed rules. Certain guarantors and other categories are also eligible. Product, firm, jurisdiction and complaint date remain relevant.

For complaints referred on or after 1 April 2026 about acts or omissions on or after 1 April 2019, FOS can require up to £455,000. The corresponding limit for earlier conduct referred from that date is £205,000. Different historical combinations have different caps. FOS may recommend more than its compulsory limit, but the business need not pay the excess unless it agrees.

What does the latest FCA complaints data reveal?

Firms reported 1.74 million complaints in the second half of 2025, down 0.4% from the revised first-half total of 1.83 million. Banking and credit-card complaints were 857,757; current accounts alone accounted for 492,149. Firms upheld 55.54% of closed complaints and reported approximately £236 million of total redress in the half.

Volume needs context: large providers serve more customers, definitions and reporting populations matter, and low complaints can reflect access barriers rather than excellent outcomes. Trends, uphold rates, cause and redress per relevant account are more informative than a league table. The FCA plans a consolidated complaints return with explicit vulnerable-customer reporting from the reporting period beginning January 2027.

When must a firm move from case resolution to remediation?

A complaint can indicate that similarly situated customers suffered the same error without complaining. Firms should perform root-cause analysis, identify the affected population and consider proactive redress. Consumer Duty monitoring strengthens that expectation where the firm detects foreseeable harm or poor outcomes. Waiting for each customer to discover a systemic defect can compound loss and unfairness.

A sound remediation establishes counterfactual outcomes, data lineage, inclusion and exclusion criteria, calculation methodology, interest, tax, contact strategy, deceased or vulnerable-customer treatment and independent quality assurance. It tracks failed payments and uncashed cheques and tests whether the underlying product or process changed. Redress without control repair is an expense, not a remedy.

What powers does the FCA have for wider redress?

The FCA can investigate, supervise, impose requirements, secure voluntary or formal remediation and take enforcement action. Under section 404 FSMA it can make rules for a consumer-redress scheme where specified conditions are met, creating a common methodology across a class of cases. The legal basis, eligible population, calculation and challenge routes are defined by the particular scheme.

A statutory scheme differs from ordinary complaint-by-complaint FOS work, although the institutions coordinate on wider implications. Industry-wide redress requires reliable data, funding capacity, consistent assumptions and governance against conflicts. Consultations, policy statements and litigation can change dates or design. Firms should separate confirmed obligations from estimated public exposure in disclosures and planning.

Where do courts and the FSCS fit?

Courts determine legal rights and can handle claims outside FOS jurisdiction or above its practical scope, but litigation brings procedure, cost and adverse-cost risk. Limitation, evidence and causes of action require legal analysis. The existence of FOS does not erase courts; accepting a binding final FOS decision affects the ability to relitigate the same dispute.

FSCS is the compensation scheme of last resort for eligible customers of failed authorised firms. Its limits depend on the protected claim: eligible deposits are protected to £120,000 from December 2025, while many investment and advice claims remain capped at £85,000. Insurance uses percentage-based protection in many cases. Regulated activity, claimant eligibility and failure status determine cover; market loss is not automatically compensable.

An accountability architecture for financial firms

Connect product approval, value assessment, communication testing, operational incidents, complaints, FOS outcomes and remediation in one taxonomy. Assign product owners and control owners, define triggers for cohort review and make legal, compliance, data and customer-operations teams share evidence. The board should see customer impact, cause, financial exposure, action owner, deadline and effectiveness—not just complaint counts.

Close the learning loop. Change the journey or product, contact affected customers, calculate and pay redress, then measure whether the outcome improved. Preserve reproducible data and decision records. Reward teams for durable outcomes rather than low recorded complaints or fast case closure. A system designed this way makes Consumer Duty part of business engineering and turns redress from a recurring clean-up operation into prevention.
