10.1 Client Relationships, Adviser Responsibilities and Types of Clients

Key Takeaways

  • The adviser-client relationship is governed by the FCA Handbook (PRIN, COBS, COCON, SMCR), common law and equity, with the adviser owing duties of skill, care, integrity and good faith.
  • COBS 3 recognises three client categories — retail, professional and eligible counterparty — each carrying a different level of regulatory protection.
  • Retail client is the default category; any client that does not qualify as professional or eligible counterparty benefits from full COBS protections including suitability, cancellation and FOS access.
  • A retail client can only be treated as an elective professional client after a written quantitative and qualitative assessment under COBS 3.5; a firm cannot silently strip protections.
  • Permissive categorisation allows a firm to treat a professional or eligible counterparty as a retail client and grant higher protections, even where not required.

The Adviser-Client Relationship

The relationship between a financial adviser and a client is the foundation of regulated financial advice in the United Kingdom. When an adviser provides a personal recommendation to a client, the adviser assumes duties that are imposed by the Financial Conduct Authority (FCA) Handbook, by the common law of contract and negligence, and by equity. The relationship is not transactional; it is built on trust, competence and integrity and continues for the duration of the engagement.

An adviser's primary responsibility is to act in the client's best interest. This duty is reinforced by the Principles for Businesses (PRIN) — in particular PRIN 2 (skill, care and diligence), PRIN 3 (management and control), PRIN 6 (customers' interests), PRIN 7 (communications with clients), PRIN 8 (conflicts of interest) and PRIN 9 (customers' reliance on the firm). The Conduct Rules (COCON) and the Senior Managers and Certification Regime (SMCR) layer personal accountability on top of firm-level obligations, so that individuals as well as firms can be held to account for breaches.

FCA Client Categories

The FCA's Conduct of Business Sourcebook (COBS) recognises three client categories, set out in COBS 3. Each category carries a different level of regulatory protection:

CategoryDefault?Regulatory protectionTypical clients
Retail clientYes (default)Full COBS protections: suitability, disclosures, cancellation, FOS accessIndividuals, small businesses
Professional clientNo, must opt-up or be per seReduced protections — deemed to understand investmentsLarge firms, regulated persons, high-net-worth electives
Eligible counterpartyNo, must opt-inFewest protections — no suitability, no cancellationAuthorised firms, governments, large corporations

Retail Clients

A retail client is the default category. Any client that does not qualify as a professional client or eligible counterparty is a retail client and benefits from the full weight of conduct protection. Retail clients receive suitability reports under COBS 9, cancellation rights under COBS 15, and access to the Financial Ombudsman Service (FOS) and the Financial Services Compensation Scheme (FSCS). The retail label exists because the regulator assumes such clients need the highest level of protection — they are presumed not to have the expertise or bargaining power of a professional.

Professional Clients

A professional client is either a per se professional client — automatically professional because of its status, such as an authorised firm, a large undertaking meeting two of the prescribed size criteria, or a national government — or an elective professional client, who is a client that agrees in writing to be treated as professional after the firm has carried out a quantitative and qualitative assessment under COBS 3.5.

For an elective professional client, COBS 3.5 requires the firm to assess the volume and frequency of the client's transactions, the size of the client's financial instrument portfolio, and the client's knowledge and experience. A retail client cannot simply be relabelled professional to remove protections; the firm must follow the prescribed opting-up process and obtain written consent.

Eligible Counterparty

An eligible counterparty is the category offering the fewest conduct protections. It applies to dealings between firms and other authorised persons, governments, central banks and certain supranational bodies. A firm may treat a professional client as an eligible counterparty only with the client's express consent (COBS 3.6), and the relationship typically involves execution of transactions on a principal or matched-principal basis without a suitability requirement.

Permissive Client Categorisation

Firms may apply permissive client categorisation — that is, they may choose to treat a client that could be categorised as professional or eligible counterparty as a retail client, and thereby grant the higher protections. This is common where a high-net-worth individual prefers the comfort of full suitability advice, cancellation rights and FOS access, even though they could be opted up. The regulator permits this because increasing protection does not create risk; reducing it does.

COBS 3 Client Categorisation Process

COBS 3 requires firms to:

  1. Categorise each new client as retail, professional, or eligible counterparty before providing services.
  2. Provide a written description of the categorisation and the protections available.
  3. Notify the client of the right to request a different categorisation.
  4. Obtain express written consent before treating a client as an eligible counterparty or as an elective professional client.

The categorisation is recorded in the client agreement (COBS 2) and feeds into disclosure, suitability, cancellation and complaint handling for the duration of the relationship. The firm must also warn an elective professional client in writing that it will lose the protections that would otherwise apply as a retail client.

Adviser Responsibilities Across the Relationship

The adviser's responsibilities span the entire relationship, not just the moment of recommendation:

  • Pre-engagement: initial disclosure of services, regulator, complaints procedure and status (independent or restricted).
  • Information gathering: a fact-find sufficient to assess suitability, including objectives, risk tolerance, capacity for loss, and existing financial position.
  • Analysis and recommendation: a suitable personal recommendation supported by a suitability report under COBS 9.
  • Implementation: accurate execution of the recommended product and correct documentation.
  • Ongoing servicing: periodic reviews and updates to the fact-find where an ongoing service is agreed.

Why Categorisation Matters for CeMAP

The client's category determines which rules apply. A retail client receives a suitability report and a 14-day or 30-day cancellation right; an eligible counterparty receives neither. The CeMAP candidate must be able to identify the correct category at the start of the relationship, explain it to the client, and recognise when an opt-up is or is not appropriate. Mis-categorising a retail client as a professional client to avoid suitability duties is a serious breach and a recurring source of FOS complaints and FCA enforcement.
