If your firm is authorised by the Financial Conduct Authority (FCA) and holds or controls client money or custody assets, a CASS (Client Assets Sourcebook) audit is a regulatory requirement and a vital safeguard for your clients and your business.

At Prydis, we deliver specialist CASS audit and assurance services to regulated firms across Devon, Cornwall, the wider South West, and nationwide. With offices in Exeter, Newquay, and Liskeard, we combine local presence with national reach, bringing a clear, commercial, and efficient approach to CASS compliance.

What Is a CASS Audit?

A CASS audit provides independent assurance that your firm is complying with the FCA’s client asset rules (CASS 5, CASS 6, or CASS 7). These audits protect client money and custody assets in the event of firm failure and they demonstrate to the FCA and your stakeholders that your systems and controls are robust and effective.

Whether you’re based in the South West or operating across the UK, Prydis ensures your audit is completed with accuracy, efficiency, and commercial awareness.

Why a CASS Audit Matters

• FCA Compliance: Avoid enforcement action by meeting all relevant FCA requirements with confidence.

• Internal Assurance: Understand your operational risks and improve your internal controls.

• Client Trust: Show your clients and investors that their assets are protected and well managed.

• Reputation Management: Reduce the risk of reputational damage from compliance failures.

Our CASS Audit Approach

We provide both reasonable and limited assurance reports depending on your regulatory classification. Our process includes:

1. Pre-Audit Assessment: Identify potential gaps in controls before formal fieldwork.

2. Efficient Audit Delivery: Conducted remotely or on-site to suit your operational model.

3. Clear, FCA-Compliant Reporting: Straightforward insights and practical recommendations.

4. Ongoing Support: Advice on strengthening future compliance and adapting to regulatory change.
