Since the 2008 collapse of Lehman Brothers, compliance with the Client Assets Sourcebook (CASS) has been a top regulatory focus. The question is: why does it remain critical, and what should regulated firms prioritise to stay ahead?
The FCA’s CASS rules aim to protect client assets in the event of a firm’s failure. Key obligations include:
These measures ensure client assets are effectively “ring-fenced,” maintaining their safety even during insolvency. At its core, CASS is about client protection—an essential cornerstone of trust in financial services.
For over a decade, the FCA has made CASS compliance a priority. The regulator has imposed significant fines and public censures on firms and individuals for failing to meet the required standards.
Additionally, the introduction of the Senior Managers and Certification Regime (SMCR) has heightened personal accountability, making compliance a shared responsibility across leadership teams.
Effective CASS management starts at the boardroom level and extends throughout your entire business. Embedding robust processes and controls at the core of your operations is essential for meeting regulatory requirements and achieving long-term success.

We assess the adequacy of your CASS governance and oversight frameworks including the review of committee papers, committee reporting structure, management information, breach escalation processes, committee terms of reference, and SMCR responsibilities.

Helping you design the full CASS operating model across people, processes and systems.

Procedures (P&P) We can develop your CASS policies & procedures from the ground up, or review your existing documentation to ensure best practices are met. We can also opine on the completeness of your P&Ps.

Preparing for a CASS audit? We can help you get ready before the auditor arrives, advise on contestable findings before the report is finalised, and assist with any remedial actions needed pre and post-audit.

We collaborate with you to design or refine your CASS processes and controls. This may include enhancing reconciliation processes, optimising record-keeping systems, or enriching your control framework.

Our health checks range from high-level reviews of your CASS arrangements to detailed, bottom-up process reviews. We provide actionable and proportionate recommendations to strengthen your CASS framework where necessary.

We deliver bespoke CASS training tailored to your firm’s needs. This can include sessions for the board, training for the reconciliation team, training for independent functions, training for the broader business, or a combination. Our training focuses on how CASS applies to your business.

We assess your products and services to ensure that all client assets are correctly identified, segregated, and safeguarded.

We perform simulated s166 test scenarios to assess the robustness of your CASS RP process. We can also review your existing CASS RP framework and documentations.

We can simulate a skilled person review to provide independent opinions on any CASS issues you’re facing.

Our team works alongside yours to evaluate your compliance with CASS rules, identify and assess the CASS risks your firm faces, and document the controls in place to mitigate these risks effectively. We also have expertise in supporting the onboarding of third-party risk mapping vendors.

Have a large CASS project or programme to manage? We have extensive experience in managing time sensitive projects that are internal only or with third-party vendors

We can be the 2nd line expertise your firm is lacking which can be on a seconded basis, for a set number of days per year, or to undertake thematic reviews.

As the FCA continues to emphasise the importance of a three lines of defence model – we can plug that gap for you in the 3rd line.

As your business evolves, products and business lines change or are added. Our deep expertise can help you navigate this minefield of CASS impact.

Inside this issue July’s theme is regulatory simplification. Across
Democratising consulting – making it seamless, accessible, and instantly within your reach.
In light of the FCA’s continued focus on firms’ compliance with CASS across the Financial Services, especially those in the Payment & Digital Assets space, businesses are expected to maintain strong, demonstrable oversight of their CASS governance, controls and operational frameworks.
However, not all firms require, or wish to bear the cost of dedicated full-time CASS resource.
To support firms in fulfilling their regulatory obligations in a proportionate and cost effective manner, we offer a range of flexible retainer services.
These provide immediate access to experienced CASS specialists, giving you the confidence and capability to remain compliant and well prepared, without the overheads of permanent staffing.
