COBS: Conduct of Business Sourcebook for Investment Firms

What It Is

The Conduct of Business Sourcebook (COBS) is the FCA's primary rulebook for firms conducting investment business, insurance mediation, and related activities. It sets out the conduct standards that apply when firms interact with clients in connection with designated investment business — from initial client categorisation through to ongoing service delivery and reporting.

COBS is one of the largest and most complex parts of the FCA Handbook. COBS 2 covers acting honestly, fairly, and professionally. COBS 3 deals with client categorisation. COBS 4 governs financial promotions — one of the most actively enforced areas of regulation. COBS 6 covers information disclosure. COBS 9A sets out the suitability requirements for personal recommendations and portfolio management. COBS 10A covers appropriateness for non-advised services. COBS 11.2A addresses best execution. COBS 14 covers client reporting. COBS 19 deals with pension transfers and opt-outs, including the pension transfer advice requirements that have generated substantial enforcement action.

COBS implements and builds upon the UK's retained EU legislation, including the Markets in Financial Instruments framework (MiFID). Since the UK left the EU, the FCA has been progressively replacing retained EU law with domestic rules, but the core COBS obligations remain substantively similar. The Handbook continues to evolve, and firms must monitor regulatory change carefully.

COBS is the sourcebook that most directly shapes the advisory relationship between firms and their clients. Every investment recommendation, every financial promotion, every portfolio management decision, and every execution of a client order is governed by COBS rules.

Why the FCA Cares

Investment business carries inherent information asymmetry: firms know more than their clients about products, markets, and risks. COBS exists to manage that asymmetry by requiring firms to act in their clients' interests, provide clear and complete information, make suitable recommendations, and execute orders fairly.

The FCA's enforcement history in COBS is extensive and instructive. Suitability failures account for some of the largest redress exercises in UK regulatory history — including the pensions mis-selling review of the 1990s, the endowment mortgage review, and ongoing DB pension transfer cases. Financial promotions enforcement has accelerated dramatically, with the FCA using its new powers over unauthorised persons and taking action against social media promotions, cryptoasset promotions, and misleading performance claims.

Best execution has become an area of renewed focus. The FCA's thematic reviews have found firms that could not demonstrate they were achieving best execution, had inadequate monitoring arrangements, or had order execution policies that did not reflect their actual practices. In an era of multiple execution venues, payment for order flow debates, and algorithmic trading, best execution is a live supervisory priority.

Consumer Duty has intensified the FCA's approach to COBS. Suitability is no longer just about matching a product to a client's stated objectives; it requires the firm to consider whether the client will achieve a good outcome. Financial promotions must not just avoid being misleading; they must support genuine consumer understanding. The bar has risen.

Who It Affects

COBS applies to firms authorised to conduct designated investment business. This includes investment advisers (both independent and restricted), discretionary portfolio managers, investment managers, stockbrokers, wealth managers, corporate finance firms, and firms that arrange deals in investments. It also applies to firms conducting insurance mediation activities (though ICOBS covers the insurance-specific overlay).

The scope is extensive. A financial adviser recommending a pension transfer is subject to COBS 9A suitability requirements and COBS 19 pension transfer rules. A wealth manager running client portfolios is subject to COBS 9A (suitability of the mandate and ongoing management decisions), COBS 11.2A (best execution), and COBS 14 (client reporting). A firm approving financial promotions is subject to COBS 4, whether the promotions are its own or those of unauthorised persons it has approved.

Firms operating through appointed representative networks must ensure that every AR complies with COBS. The principal firm's regulatory permissions define what activities the AR can conduct, but COBS compliance is a continuous obligation that requires ongoing oversight. The FCA has been particularly critical of principals whose COBS oversight of ARs is inadequate, especially in financial promotions.

Fund managers face COBS obligations in their interactions with retail investors (including through fund prospectuses and Key Investor Information Documents) and in their best execution obligations when trading on behalf of fund portfolios.

What Firms Get Wrong

Suitability failures remain the most significant area of COBS non-compliance. The FCA continues to find firms that make recommendations without obtaining sufficient information about the client, that recommend products mismatched to the client's risk profile or investment horizon, or that fail to consider the cost of the recommendation relative to available alternatives.

A specific and persistent failure is in ongoing suitability. COBS 9A requires firms providing ongoing advisory or discretionary services to conduct periodic suitability assessments. Many firms collect an annual review fee but do not conduct a meaningful annual review. The FCA has been explicit that charging for ongoing service creates an obligation to deliver ongoing service, and that a firm charging 0.5% per annum for advice that consists of an annual letter confirming no changes are recommended may not be delivering fair value.

Financial promotions compliance is a growing area of failure. The FCA introduced a new financial promotions gateway in February 2024, and firms that approve promotions for unauthorised persons face heightened responsibilities. Common failures include: inadequate risk warnings, misleading performance data (particularly cherry-picked time periods), failure to ensure promotions are targeted at appropriate audiences, and approving promotions without sufficient due diligence on the underlying product or service.

Best execution monitoring is frequently inadequate. Firms have order execution policies that they review annually but do not actively monitor. COBS 11.2A requires not just a policy but ongoing monitoring of execution quality — sampling trades, comparing execution outcomes across venues, and assessing whether the policy achieves best execution in practice. Firms that cannot produce monitoring evidence are in breach even if their actual execution quality is good.

Client categorisation errors, while less common, can have serious consequences. A client incorrectly categorised as professional when they should be retail loses the protections COBS provides — suitability assessment, full disclosure, and best execution. The FCA has found firms that routinely opt clients up to professional status to reduce their regulatory burden, without meeting the conditions for re-categorisation.

What Evidence the FCA Expects

For suitability, the FCA expects a documented record for every personal recommendation showing: the client's knowledge, experience, financial situation, and investment objectives; the range of products or strategies considered; the rationale for the specific recommendation; how the recommendation is suitable for the client's circumstances; and evidence that the client understood and consented. Template-based suitability reports that do not reflect the individual client's circumstances are treated as evidence of a systemic failure.

For financial promotions, the FCA expects a documented approval process with clear records showing who approved each promotion, what due diligence was conducted, and on what basis the promotion was assessed as fair, clear, and not misleading. A promotions log must be maintained.

For best execution, the FCA expects: a current order execution policy that reflects the firm's actual practices; monitoring data showing execution quality across venues and instrument types; and evidence of annual policy reviews incorporating monitoring findings. The RTS 28 reporting obligation (or its post-Brexit equivalent) requires firms to publish data on their top five execution venues.

Client categorisation records must show how each client was categorised, the basis for the categorisation, and any subsequent re-categorisation together with the rationale and evidence that the conditions were met.

Management information should track suitability review completion rates, financial promotions approval and withdrawal data, best execution monitoring outcomes, and complaint trends. The FCA uses this MI to assess whether COBS compliance is embedded or superficial.

Good Implementation

A firm with strong COBS compliance treats the suitability process as the foundation of its client relationship. Client fact-finding is thorough and regularly updated. Recommendations are genuinely personalised — the suitability report reads as if it was written for this client, not adapted from a template. Ongoing suitability reviews are substantive, assessing whether the client's circumstances have changed and whether the existing strategy remains appropriate.

Financial promotions go through a rigorous approval process regardless of the medium. The firm has a named individual responsible for promotions approval, clear criteria for assessment, and a withdrawal process for promotions that are no longer accurate. Social media promotions are subject to the same standards as printed materials.

Best execution is actively managed. The firm selects execution venues based on a genuine assessment of execution quality, monitors outcomes on an ongoing basis, and adjusts its approach when monitoring reveals deficiencies. The order execution policy is a working document that reflects current practice, not a compliance artefact filed and forgotten.

Client categorisation is conducted at onboarding and reviewed periodically. The firm resists pressure to categorise clients as professional unless the conditions are genuinely met. Where a client requests re-categorisation, the firm conducts a thorough assessment and documents its conclusion.

Training is continuous. Advisers receive regular updates on regulatory changes, enforcement outcomes, and emerging good practice. Competence assessments go beyond exam qualifications to assess practical advisory skill, including file quality and client outcomes.

How Our Tool Helps

The MEMA financial promotions tool provides a structured approval workflow for financial promotions across all media. It captures the approval rationale, due diligence conducted, and compliance assessment for each promotion, maintaining the audit trail COBS 4 requires. The tool flags common compliance issues — missing risk warnings, unbalanced performance data, unclear target audience — before promotions are published.

The Consumer Duty tool integrates with your COBS suitability process, helping you assess whether recommendations deliver good outcomes and whether ongoing service justifies ongoing charges. It tracks suitability review completion, flags overdue reviews, and generates MI that demonstrates to the FCA that your ongoing suitability obligations are being met in substance.

Together, these tools provide a compliance infrastructure that addresses the two areas of COBS that generate the most regulatory scrutiny: advice suitability and financial promotions.

How Our Service Helps

Our compliance outsourcing service provides independent suitability file reviews conducted by experienced compliance practitioners. We assess files against COBS 9A requirements and current FCA expectations, providing detailed feedback to individual advisers and identifying systemic themes that require management action. Our file reviews are calibrated to the standard the FCA applies, not a minimum compliance threshold.

For firms seeking to strengthen their financial promotions compliance, we provide promotions review and approval support — either as part of an outsourced compliance arrangement or as a standalone service. We review promotions against COBS 4, Consumer Duty, and the FCA's published guidance, ensuring that your promotions meet current regulatory expectations.

Our regulatory training service covers the COBS topics that matter most: suitability assessment methodology, financial promotions compliance, best execution obligations, and the interaction between COBS and Consumer Duty. Training is practical and scenario-based, drawing on real enforcement cases and FCA findings to illustrate what good and bad look like in practice.

Relevant Sectors

Wealth management firms face the broadest and most intensive COBS obligations. Suitability, best execution, client reporting, and financial promotions all apply, often simultaneously, and the FCA's supervisory attention to the wealth sector is sustained. Ongoing advice charges and the suitability of model portfolios are current areas of focus. Firms that charge percentage-based fees must demonstrate under Consumer Duty that the value delivered justifies the charge as client assets grow.

Corporate finance firms face COBS obligations principally in relation to client categorisation and conflicts of interest. The FCA has examined how corporate finance firms manage conflicts between advisory mandates and their other business interests, and whether client categorisation is conducted appropriately.

Fund management firms face COBS obligations in relation to best execution (when trading on behalf of fund portfolios), financial promotions (fund marketing materials and factsheets), and disclosure (Key Investor Information Documents and prospectuses). The FCA has focused on whether fund managers' best execution arrangements are adequate and whether fund performance reporting is fair and not misleading.

Across all sectors, the firms at greatest COBS risk are those where advisory or promotional activity has outpaced the compliance infrastructure. Rapid growth in adviser numbers, expansion into new product areas, or the launch of digital marketing channels all create COBS compliance pressure that must be matched by corresponding investment in oversight, monitoring, and quality assurance.
