Supreme Court clarifies undisclosed commissions and fiduciary duty for brokers and lenders

The UK Supreme Court’s decision in Hopcraft and another v Close Brothers, Johnson v FirstRand (t/a MotoNovo) and Wrench v FirstRand is now the leading authority on undisclosed commissions in brokered credit, and on when fiduciary duties and the tort of bribery are engaged.

Although the appeals concerned motor finance, the reasoning has broader implications for mortgage brokers, insurance brokers, independent financial advisers (IFAs) and lenders operating in the UK’s regulated markets. This article explains the judgment, assesses its regulatory and operational impact and offers practical recommendations for firms.

The decision

The Supreme Court held that motor dealers arranging hire purchase finance don’t owe customers a fiduciary duty of undivided loyalty when sourcing finance. In the classic tripartite car purchase on credit, the dealer remains an arm’s length seller pursuing its own commercial objective – completing a profitable vehicle sale – while facilitating finance as an ancillary step. On those facts, equity doesn’t imply a duty to act selflessly in the customer’s interests. The court emphasised that fiduciary obligations arise only where the alleged fiduciary undertakes such a duty, expressly or impliedly, in a way consistent with the overall contractual and regulatory context.

On bribery, the court confirmed the distinct tort of bribery and its strict remedies, but held that it is engaged only where the recipient of the payment owes a fiduciary duty to the claimant. A purely contractual ‘disinterested’ or impartiality duty is insufficient, because liability for bribery requires a fiduciary relationship. Fully informed consent, based on disclosure of all material facts, negates bribery. What counts as ‘material’ depends on context.

The court also preserved the established analysis for unfair relationship claims under s140 of the Consumer Credit Act 1974 (CCA). In Mr Johnson’s case, the relationship with the lender was deemed unfair under s140A due to the size of the undisclosed commission, non-disclosure of a first-refusal tie between broker and lender that contradicted ‘panel’ messaging and the manner of disclosure to an unsophisticated customer.

The court endorsed a non-exhaustive list of relevant factors, including:

• The size and nature of commission
• Consumer characteristics
• The extent and manner of disclosure (including pre-contract negotiations deemed to be on behalf of the lender under s56 CCA)
• Compliance with applicable regulatory rules.

Implications for brokers and advisers across sectors

Although the appeal concerned motor finance, the decision affects multiple sectors which operate by way of commission-based arrangements with their customers.

For mortgage brokers, insurance brokers and IFAs, the core message is that fiduciary duties will not be implied simply because a firm intermediates or influences a consumer’s decision. In commercial contexts, equity looks for a clear undertaking of loyalty; without that, a firm’s self-interest in distribution and remuneration remains compatible with an arm’s length relationship. Many advisory models in mortgages, insurance distribution and retail investments already sit under sectoral conduct standards that go beyond the dealer setting.

In retail investments, commission on advised sales has been prohibited for over a decade. IFAs providing personal recommendations must comply with best-interests and suitability standards under the FCA’s COBS rules and the Retail Distribution Review effectively restructured remuneration. Those frameworks align more closely with an expressly undertaken loyalty paradigm and reduce bribery risk because contingent third-party commissions are removed.

Mortgage and insurance distribution remain commission-permitted, but are governed by extensive disclosure, conflicts management and suitability/appropriateness requirements in MCOB and ICOBS, grounded in FSMA principles and the Consumer Duty. The Supreme Court’s reasoning reinforces that these sectoral duties form the primary lens for assessing broker conduct and lender oversight. Where an intermediary explicitly undertakes to act in a client’s best interests, or provides personal recommendations implying an undertaking of loyalty, the risk profile changes. In such cases, failure to disclose material remuneration and conflicts could raise equity questions and would almost certainly be actionable under the FCA Handbook and consumer redress regimes.

The court’s approach to s140A is particularly relevant wherever the CCA applies, including second-charge mortgages, certain secured consumer loans and retail credit. Even in markets outside the CCA, the same logic – the size and nature of remuneration, customer characteristics and how and when conflicts are disclosed – aligns with the FCA’s outcomes-based regulation and the Consumer Duty. The upshot is that fairness, clarity and prominence of disclosure matter more than labels.

Operational and regulatory impact for firms

For brokers, the judgment reduces the litigation risk of common law bribery in routine, arm’s length commission models by confirming that fiduciary duties are not lightly implied. However, it raises the importance of accurate, prominent and timely disclosures, and of alignment between customer messaging and the true nature of distribution arrangements. Claims about ‘panels’ must reflect reality; exclusivity or first-refusal arrangements should be made clear if they could affect impartiality or a customer’s decision.

For lenders, s56 CCA’s deemed agency effect means broker pre-contract communications may be attributable to the lender in regulated credit. The Supreme Court’s unfairness analysis shows that lenders may bear the consequences where broker disclosures are partial, buried or contradicted by contractual ties. This impacts oversight, due diligence and contractual controls over intermediaries’ customer journeys, especially where commission levels or structures could create incentives that conflict with good outcomes.

The regulatory context remains critical. FCA Principles, CONC and sectoral rulebooks don’t impose fiduciary duties, but they require fair treatment, conflicts management and clear, fair and not misleading communications, with the Consumer Duty now setting a higher benchmark for retail customer outcomes. The court recognised that these frameworks shape reasonable expectations, highlighting the need for firms to ensure remuneration, distribution and product governance arrangements both deliver – and can evidence – compliant outcomes in practice.

Risks and opportunities

The main litigation risk has moved away from bribery claims in non-advisory, arm’s length models. It now centres on unfairness and regulatory breach where disclosure is weak, commissions are large relative to cost of credit or premium, distribution ties are concealed or mischaracterised, or customer journeys fail Consumer Duty tests.

The flip side is an opportunity: firms that standardise transparent remuneration disclosure, align broker scripts and documents with reality and strengthen oversight can materially reduce redress exposure and customer detriment.

For IFAs, the decision highlights the value of transparent advice models that structurally avoid third-party conflicts. For mortgage and insurance brokers, a robust approach to commission disclosure – covering existence, nature and amount where material to a customer’s decision – together with clear descriptions of market scope and any exclusivity, will place firms on the right side of both the court’s logic and the FCA’s expectations.

Recommended actions

Brokers should:

• Review customer-facing statements, mandates and service descriptions to ensure they don’t imply undivided loyalty unless that is the intended model supported by systems and controls
• Where firms state they search a panel or the market, ensure the panel’s scope and any first-refusal or exclusivity are clearly explained
• Enhance prominence and timing of commission disclosures, focusing on the ‘extent and manner’ factors highlighted by the court
• Document rationale where commission size could reasonably affect a transactional decision.

Lenders should:

• Map broker networks against disclosure quality, commission levels and distribution ties, prioritising remediation where risk indicators are highest
• Tighten intermediary terms to mandate prominent disclosures consistent with Handbook rules and the Consumer Duty
• Require evidence of delivery and implement targeted sampling and management information to evidence compliance, particularly given s56 attribution risk in CCA credit.

Across sectors, firms should:

• Test whether remuneration structures could predictably lead to poorer outcomes for certain customer groups and, if so, mitigate or redesign
• Train frontline personnel to explain the nature of their service, market scope and remuneration, tailored to customer sophistication
• Strengthen record-keeping to evidence disclosures, customer understanding and reasons for recommendation where applicable, creating defensible files for both regulatory and court scrutiny.

Conclusion

The Supreme Court has set clear limits on when fiduciary duties and bribery claims arise in brokered credit, while confirming that fairness under the CCA – and under the FCA’s regime more broadly – turns on substance. This includes the size and nature of incentives, the realities of distribution ties, customer characteristics and the clarity and prominence of disclosure.

For mortgage brokers, insurance brokers, IFAs and lenders, the path forward is to prioritise transparency, ensure customer communications reflect distribution reality and align remuneration with good outcomes. Those that do so will reduce litigation risk, meet regulatory expectations and earn the trust that turns compliant sales channels into durable businesses.
