CASS 5 Client Money for Insurance Brokers Explained

Welcome to another episode from SMF Capital, exploring the people and expertise required by FCA-regulated businesses.

Today, we're looking at CASS 5, the FCA's client money rules for insurance brokers and intermediaries. We'll explain the main requirements, common problems and why having the right finance and compliance professionals is essential.

Read the full guide at SMF Capital – CASS 5 Client Money.

What is CASS 5?

CASS 5 applies to insurance intermediaries that receive or hold money for clients in connection with insurance distribution.

Examples include premiums collected before being paid to insurers, and claims or refunds received before being passed to customers.

The objective is to protect client money if an insurance broker fails. Firms need appropriate arrangements, accurate records and effective controls to ensure money is handled correctly.

Understanding risk transfer

Risk transfer is one of the most important concepts in insurance broker accounting.

Where an appropriate risk transfer agreement exists, money received by the broker as the insurer's agent is treated as received by the insurer. That money is not client money under CASS 5.

However, many brokers handle a mixture of risk-transfer money and client money. They must understand which category each payment belongs to and ensure their records reflect the distinction.

Getting this wrong can affect calculations, reconciliations and audit results.

Statutory and non-statutory trusts

Insurance brokers need to understand the trust arrangements governing their client money.

A statutory trust is the default arrangement under CASS 5. A non-statutory trust can offer greater flexibility, including allowing credit to be advanced in certain circumstances, such as paying an insurer before a customer has paid.

That flexibility comes with additional conditions, higher minimum capital requirements and stronger control expectations.

The choice of trust should therefore be made with appropriate professional advice, taking account of the firm's business model and cash-flow requirements.

Client bank accounts and acknowledgement letters

Client money must be held in designated accounts, separate from the firm's own money, with the appropriate bank acknowledgement that the funds are held on trust.

Where money passes to other parties, equivalent protections and acknowledgements may also be required.

Missing or outdated acknowledgement letters are a common audit weakness. Brokers should ensure the arrangements remain accurate as banking relationships and business processes change.

The client money calculation

Firms must regularly check that their client money resources cover their client money requirements.

The calculation must be performed at least every 25 business days. Depending on the firm's arrangements, it can use the client balance method or the accruals method.

Any shortfall must be corrected on the same day, using the firm's own money where necessary. Excess client money must also be addressed appropriately.

Records should be reconciled against bank statements, differences investigated promptly and supporting evidence retained. Money handled by appointed representatives must also be included where required.

If a firm cannot perform the calculation or correct a shortfall, it must notify the FCA immediately.

These are ongoing operational responsibilities, not simply year-end accounting tasks.

Why insurance accounting expertise matters

CASS 5 requires people who understand how insurance money moves through the business.

Relevant experience may include insurance premiums, insurer and customer ledgers, unearned commission, risk transfer arrangements, client money calculations and reconciliations.

A general bookkeeper may have strong accounting skills but lack the specialist knowledge needed to manage these requirements effectively.

That is why insurance-specific client money experience is important when recruiting finance professionals.

Who is accountable?

Under the Senior Managers and Certification Regime, responsibility for CASS compliance is allocated to a Senior Manager through a Prescribed Responsibility.

At a smaller broker, this might be the managing director or compliance officer. In a larger organisation, it could be the Finance Director.

The responsible Senior Manager needs appropriate management information and evidence that the controls are operating effectively.

Although tasks can be delegated, accountability for the overall arrangements cannot simply be handed to a junior employee.

The three key roles

Effective client money oversight can involve three distinct responsibilities.

First, the finance professional prepares the calculations, maintains records and performs reconciliations.

Second, the compliance officer oversees the regulatory framework, challenges weaknesses and checks that controls are effective.

Third, the Senior Manager holding the CASS Prescribed Responsibility maintains appropriate oversight and receives sufficient information to understand the firm's position.

In smaller businesses, some duties may be combined, but responsibilities and appropriate checks still need to be clear.

Experience also needs to match the regulatory regime. Knowledge of CASS 7 at an investment firm does not automatically provide the specialist understanding of insurance risk transfer and trust arrangements required under CASS 5.

CASS audits and common weaknesses

Insurance brokers holding client money must meet the relevant reporting requirements and obtain an annual client assets report from their auditor, which is sent to the FCA.

Auditors examine calculations, reconciliations, bank arrangements, acknowledgement letters and internal controls.

Common weaknesses include late calculations, uncorrected shortfalls, missing bank acknowledgements, poor reconciliations and inadequate review.

Using client money to fund the firm's own cash flow can be particularly serious.

A qualified audit report or significant control failures may attract further regulatory scrutiny. A sound framework must therefore operate throughout the year, not just before the audit.

Appointed representatives

Where appointed representatives handle premiums, the principal needs to understand how that money is managed and ensure the relevant amounts are included in its client money calculations.

Weak oversight of ARs can create additional risks and potential shortfalls.

As a broker expands its AR network, it may need stronger monitoring processes and clearer reporting to maintain effective control.

Setting up CASS 5 at a new broker

New brokers should establish their client money arrangements before they begin receiving premiums.

This involves mapping money flows, agreeing risk transfer arrangements, choosing the appropriate trust structure, opening designated accounts and establishing the calculation method.

The firm should also appoint an auditor and decide who prepares, reviews and oversees the calculations.

Planning these arrangements early helps demonstrate how client money will be protected and supports a more effective authorisation process.

Finding the right people

Consider a growing commercial broker whose auditor identifies repeated client money shortfalls that were not corrected on the same day. The calculations were being prepared by a bookkeeper without specialist review.

The solution may involve recruiting a finance manager with insurance accounting experience, introducing a formal review process and appointing a fractional compliance officer with CASS 5 expertise.

The Senior Manager responsible for CASS can then receive better information and exercise more effective oversight.

The goal is not merely to pass the next audit. It is to build controls that work consistently.

How SMF Capital can help

As insurance brokers grow, finding people with the right combination of accounting, compliance and insurance experience can be challenging.

SMF Capital supports recruitment for insurance brokers and other FCA-regulated businesses, including fractional, interim and permanent compliance appointments. We can also help firms identify finance professionals with relevant client money experience.

The key is matching the candidate's experience to the firm's actual requirements rather than assuming that knowledge of another regulatory regime is sufficient.

Every SMF Capital broker search is overseen by Adrian Lawrence FCA.

Final thoughts

CASS 5 is about protecting client money through accurate calculations, appropriate trust arrangements, effective reconciliations and clear accountability.

The finance team needs to understand the numbers. Compliance needs to challenge the controls. And the Senior Manager holding the relevant responsibility needs sufficient information to maintain effective oversight.

For brokers preparing for authorisation, growing their business or addressing client money weaknesses, getting the right people in place can make a substantial difference.
