The UK Financial Conduct Authority introduced the Consumer Duty, an outcomes-based rule requiring financial firms to prove that products, pricing, support and communications deliver good outcomes for retail customers.

The dilemma

UK retail financial services had for decades been regulated through detailed, prescriptive rules layered on top of a general “Treating Customers Fairly” principle. Despite this, the sector experienced repeated large-scale consumer harm, most visibly Payment Protection Insurance (PPI) mis-selling, which generated tens of billions of pounds in redress. As products digitalised, distribution chains lengthened, and vulnerable-customer needs became more visible after the pandemic and cost-of-living pressures, the FCA judged that rules alone were being satisfied on paper while some firms still produced poor value or confusing outcomes for customers. 

The regulatory gap

Existing Principles for Businesses and product-level rules did not require firms to actively evidence that specific customer outcomes, value, understanding, support, suitability,  were actually being achieved. Compliance could be demonstrated through process (disclosures issued, forms completed) rather than through proof of good outcomes. Regulatory intervention was largely reactive, occurring after harm had crystallised and often years after a product was sold. Retail customers, and particularly vulnerable customers, bore the risk of continued poor-value products, weak exit or switching terms, and opaque or jargon-heavy communications, with accountability increasingly diffused across multi-firm distribution chains where no single party could be pinned to the end customer outcome.

The approach

Following consultation, the FCA introduced final Consumer Duty rules and guidance in July 2022. The Duty itself came into force in two stages: from 31 July 2023 for new and existing products and services, and from 31 July 2024 for closed products and services – a phasing that matters for reading the results below, since most of the evidence gathered so far covers only the period since July 2023.

At its centre is a new Consumer Principle requiring firms to “act to deliver good outcomes for retail customers.” This is supported by cross-cutting rules requiring firms to act in good faith, avoid foreseeable harm, and enable and support retail customers to pursue their financial objectives.

The framework defines four outcomes against which firms should assess their performance:

• Products and services: products and services should be designed to meet the needs, characteristics and objectives of an identified target market.
• Price and value: firms must assess whether products and services provide fair value.
• Consumer understanding: communications should support customers in making informed decisions.
• Consumer support: firms should provide support that meets customers' needs throughout their relationship with the firm.

A distinctive feature of the model is its emphasis on evidence. Firms are expected to monitor whether they are delivering the required outcomes, identify poor outcomes and take action where necessary. Their governing bodies must review and approve an assessment of whether the firm is delivering good outcomes at least annually.

The FCA has subsequently used supervisory and multi-firm reviews and published examples of good and poor practice to support firms in understanding and improving implementation.

Results achieved

The FCA reports tangible early benefits for consumers. Following base-rate increases of 0.25 percentage points between July 2023 and February 2024, firms increased easy-access savings rates by an average of 0.45 percentage points. The FCA has not claimed this increase as a proven result of the Duty, but it estimates that a change of this size could deliver around £4 billion in additional annual interest to savers if sustained across the market. A related intervention on GAP insurance commission structures is expected to save consumers a further £70 million.

Evidence of implementation is more mixed. The FCA’s December 2024 review of the first annual Consumer Duty board reports, covering 180 firms, found genuine engagement with the Duty’s four outcomes, but uneven evidence that those outcomes were actually being achieved. Many firms still relied on measures of whether processes had been completed rather than data showing what customers experienced, with particular gaps for vulnerable customers and outsourced distribution. Reviews of 20 large insurers and 23 payments firms similarly found that outcomes monitoring needed to mature. A subsequent review of 80 firms found progress, but continuing weaknesses in demonstrating outcomes consistently across the full customer base rather than selected samples.

The shift also carries costs. Implementing the Duty can be particularly demanding for smaller firms and those operating legacy or closed-book systems. In response to industry feedback and its own implementation experience, the FCA has begun simplifying aspects of the framework and clarifying its scope, seeking to preserve the Duty’s outcomes-based approach while reducing unnecessary regulatory burden.

The transferable lesson

The UK experience illustrates how regulators can move beyond compliance with prescribed processes by defining the outcomes they expect regulated firms to achieve and requiring firms to generate evidence that those outcomes are being delivered.

Three features are particularly relevant for other regulators:

• Define the destination without prescribing every route. Clearly specified outcomes can provide a common regulatory standard while giving regulated entities flexibility in how they achieve it.
• Make evidence part of the regulatory model. Outcomes-focused regulation depends on firms being able to monitor, test and demonstrate what customers experience in practice.
• Combine flexibility with active supervision. Greater discretion places additional demands on firms' data, governance and judgement and requires continuing supervisory engagement to identify weaknesses and clarify expectations.

The case also highlights an important trade-off. Outcomes-focused regulation can make a framework more adaptable to different business models and changing markets, but flexibility can create uncertainty about what constitutes sufficient compliance. Effective implementation therefore depends on the combination of clear outcomes, evidence, governance and continuing regulatory feedback, rather than high-level principles alone.
