CASS Accountant Job Description and Salary Guide

The CASS accountant is one of the most specialised — and most in-demand — roles in UK financial services finance. Charged with protecting client money and safe custody assets under the FCA’s CASS rules, it is a role where the stakes are unusually high (the FCA has repeatedly fined firms for CASS failings) and the skilled population is unusually small. This guide provides a complete CASS accountant job description, including a copy-ready template, and a UK salary guide: what the role does, the CASS rules it lives by, the skills and qualifications it demands, and what it pays across levels and sectors. It supports our CASS accountant recruitment practice within the wider FCA-regulated finance group.

What a CASS accountant does

At its core, the CASS accountant ensures that client money and client assets held by a regulated firm are protected in line with the FCA’s Client Assets Sourcebook — kept separate from the firm’s own money, correctly recorded, reconciled to prescribed standards, and available to be returned to clients even if the firm fails. It is finance, control and compliance in one role, and it exists because the consequences of getting it wrong are severe: client money that is commingled, mis-reconciled or unaccounted for is the kind of failure that ends firms and draws enforcement. The day-to-day is a discipline of reconciliation, record-keeping, calculation and oversight, performed to a cadence and an evidence standard the rules prescribe, with the firm’s clients — and the regulator — as the ultimate stakeholders. Our introduction to client money covers the foundations, including the statutory trust under which client money is held.

The CASS rules in brief: what the role lives by

The role is defined by the sourcebook it enforces, published in the CASS section of the FCA Handbook. CASS 6 governs custody assets — the safe custody of clients’ investments — covering segregation, records, and the reconciliations that prove the firm holds what its records say. CASS 7 governs client money — money the firm holds for clients in the course of investment business — requiring segregation in designated client bank accounts backed by acknowledgement letters, the client money calculation that determines how much must be segregated, and the internal and external reconciliations that prove it. CASS 8 covers mandates, CASS 5 insurance intermediaries, CASS 1A firm classification and CASS 10 the resolution pack.

The two reconciliations at the heart of the role are the internal client money reconciliation (the firm’s record of what it owes clients, the client money requirement, against the client money it actually holds, the resource) and the external reconciliation (the firm’s records against the bank and custodian statements). Under CASS 7 the internal reconciliation is performed each business day, with any shortfall generally made good from the firm’s own money by the end of that day; the external reconciliation is performed as regularly as necessary and at least monthly. Our CASS reconciliation guide covers the mechanics, and our guide to the CASS audit explains how auditors test them.

Core responsibilities: the job description

A CASS accountant job description typically covers the following.

• Reconciliations: performing (or overseeing) the internal and external client money and custody reconciliations to the required frequency — daily for the CASS 7 internal reconciliation — investigating and resolving differences, and escalating breaks.
• The client money calculation: preparing the calculation that determines the client money resource and requirement, and ensuring the correct amount is segregated.
• Records and segregation: maintaining the books and records the rules require, ensuring client money and assets are segregated in properly designated and acknowledged accounts.
• Breach identification and reporting: spotting CASS breaches, logging them, and reporting through the firm’s governance — a critical responsibility, as unreported breaches compound quickly.
• Regulatory returns: preparing or contributing to the Client Money and Asset Return (CMAR), submitted monthly through RegData by CASS medium and large firms.
• The CASS audit relationship: supporting the annual CASS audit, providing evidence, and remediating findings.
• CASS oversight and MI: in senior roles, owning the CASS oversight function, producing management information for the board and the senior manager responsible for CASS, and maintaining the CASS resolution pack.
• Governance and policy: maintaining CASS policies and procedures, and supporting the senior manager who holds CASS responsibility under the SMCR.

CASS oversight vs CASS operations

A distinction worth understanding when hiring: CASS roles split broadly into operations and oversight. CASS operations is the doing — performing the reconciliations, preparing the calculations, maintaining the records; a role for a strong, detail-disciplined accountant. CASS oversight is the governing — monitoring that the operational controls are working, producing MI, owning the policy framework, maintaining the resolution pack, and supporting the accountable senior manager; a more senior role requiring judgement and the standing to challenge. Smaller firms combine the two; larger firms separate them. A firm hiring should be clear which it needs — a doer, a governor, or in smaller firms someone who can genuinely do both. Our guide to CASS oversight versus CASS operations sets out the boundary in more detail.

Skills and qualifications

The CASS accountant needs a specific combination. A professional qualification (ACA, ACCA or CIMA) is standard, though the role is as much about regulatory knowledge as accounting technique. CASS knowledge is the defining requirement — genuine familiarity with the relevant chapters, ideally acquired through hands-on experience rather than a course. Reconciliation discipline and exceptional attention to detail are non-negotiable: this is a role where a small error has large consequences. Investigative rigour — the ability to chase a reconciliation break to its root cause rather than plugging it. And the judgement and standing to escalate: a CASS accountant who spots a breach must be willing and able to raise it, which takes both integrity and organisational confidence. For senior oversight roles, add governance experience and the gravitas to challenge the business. The pool holding this combination is small, which is the central fact of CASS recruitment.

CASS accountant salary guide

CASS experience commands a consistent premium over equivalent non-regulated finance roles, reflecting the scarcity of the skill and the risk the role manages. Typical current ranges for permanent base salary:

The premium over non-regulated equivalents typically runs 15–25%, largest for the specialist oversight roles, and the very senior oversight roles — particularly where the holder is close to the SMCR-accountable individual — can exceed these ranges in large or complex firms. Interim CASS specialists are in strong demand for remediation projects, audit preparation and cover, at the day rates shown. See our regulated-firm finance salary guide and the full set of salary guides.

Where CASS accountants work

The role exists wherever a firm holds client money or assets under FCA regulation: investment managers and wealth managers, stockbrokers and platforms, interdealer brokers, insurance intermediaries holding client money, and the custodians and administrators serving them. Payments and e-money firms are now a fast-growing group: since 7 May 2026 their safeguarding obligations have been set by a new chapter, CASS 15, alongside the Payment Services Regulations 2017 and the Electronic Money Regulations 2011 — see our guide to the safeguarding regime and our comparison of CASS 7 and CASS 15 experience. Demand has been driven up by regulatory focus, the growth of platforms and wealth management, and the spread of CASS-style discipline into payments safeguarding and the emerging cryptoasset rules. The result is a candidate market where demand consistently outruns the specialist supply, and where firms increasingly recruit CASS-adjacent talent — safeguarding, reconciliation and audit specialists — and develop them into full CASS capability.

A day in the life: what the role actually feels like

The job description lists responsibilities; the lived reality is a daily rhythm built around the reconciliations. A client-money CASS accountant’s morning typically begins with the client money calculation and internal reconciliation as at the close of the previous business day — confirming the segregated amount matched the requirement, investigating any difference before it ages. External reconciliations against bank and custodian statements follow their own cadence. Breaks — differences between records and reality — are the day’s real work: each one classified, chased to its cause, and resolved or escalated, because a break left to age is a breach in waiting. Around this core sit the periodic tasks: oversight MI, resolution pack updates, the CASS implications of new products or accounts, and the evidence file the annual audit will read. Month-end brings the CMAR at medium and large firms and the reconciliation of the CASS numbers to the general ledger; audit season brings the intensive preparation and the auditor’s scrutiny. The professionals who thrive in it find satisfaction in a clean reconciliation and a well-evidenced control.

How the role fits the firm’s governance

A CASS accountant never operates in isolation; the role sits inside a governance structure the SMCR defines. At CASS medium and large firms, responsibility for CASS is a prescribed responsibility allocated to a named senior manager — usually the CFO, the COO or the Head of Compliance — who is accountable to the FCA for the firm’s client-asset arrangements. A CASS oversight manager or function, which may report to that senior manager, owns the monitoring framework. The CASS accountant provides the operational substance beneath: the reconciliations, calculations and records that make the accountability real, and the MI that lets the oversight layer do its job. A CASS accountant needs to know who they escalate to and whose accountability their work supports. Firms hiring should ensure the reporting lines are clear before the hire, because a CASS accountant without a defined escalation route is a control weakness dressed as a role. Our guide to SMCR for finance teams covers the accountability framework; senior manager appointments are handled by sister firm SMF Capital, or by FD Capital where the responsibility sits with a CFO or Finance Director.

Career path and progression

CASS offers a genuine specialist career, and understanding the progression helps both candidates and employers. The path typically runs from CASS analyst or accountant (operations) through senior CASS accountant, into CASS manager and oversight roles, and up to Head of CASS or Head of CASS Oversight. From there, the routes broaden: some move into wider regulatory or compliance leadership, some into financial-services finance leadership (a Financial Controller for a regulated firm who understands CASS deeply is highly valuable), and some into consultancy or audit. The specialism also increasingly bridges into adjacent regimes — payments safeguarding under CASS 15 and the emerging cryptoasset rules borrow CASS discipline. For a qualified accountant weighing the specialism, the combination of scarcity, premium and multiple forward paths makes it one of the more rewarding niches in financial services finance, and our guide on building a regulated-sector finance career covers the wider landscape.

Hiring a CASS accountant: practical advice

For firms recruiting, several principles improve the outcome. Be precise about operations versus oversight, and about which CASS chapters matter for your business — a custody-heavy firm and a client-money-heavy firm need different emphases. Recognise that the strongest candidates are employed and passive, so a search that relies on advertising will underperform one that approaches the market directly. Test CASS knowledge concretely — the breach-scenario questions in our companion CASS accountant interview guide are built for exactly this — rather than accepting “CASS experience” at face value, because the depth varies enormously. Consider the CASS-adjacent pools (safeguarding, reconciliation, regulated-audit specialists) as a route to widening a thin market, particularly for operations roles where the discipline transfers. And price the role to the scarcity: a CASS search conducted at generic finance rates will not attract the specialists. Our guide to hiring regulatory experience covers the wider approach.

The cost of getting CASS wrong

The business case for hiring CASS capability properly is written in enforcement history. CASS breaches are among the FCA’s most consistently penalised failures, because they go to the heart of consumer protection — client money that is not properly segregated or reconciled is client money at risk if the firm fails. The consequences of weakness escalate through a familiar ladder: FCA information requests and increased supervisory attention; skilled-person reviews (section 166) commissioned at the firm’s expense; requirements and restrictions on the business; significant financial penalties; and, in serious cases, personal consequences for the senior manager holding CASS accountability under the SMCR. Beyond enforcement, weak CASS arrangements surface in the annual CASS audit as qualified reports and findings that must be remediated and in transactions, where acquirers and investors treat CASS weakness as material risk. The FCA’s client money and assets pages set out its expectations. Against all of this, the cost of a capable permanent CASS accountant is modest: the role is not an overhead but insurance on the firm’s permission, its client relationships and, ultimately, its licence.

Frequently asked questions

Does a CASS accountant need to be qualified?

Usually yes (ICAEW, ACCA or CIMA), though CASS knowledge and reconciliation discipline matter as much as the qualification; some strong operations candidates are qualified by experience with deep CASS backgrounds.

What is the difference between a CASS accountant and a regulatory reporting accountant?

CASS concerns client-money and asset protection; regulatory reporting concerns the prudential returns a firm files — related regulated-finance disciplines that sometimes combine in smaller firms but are distinct specialisms.

Can a firm outsource CASS?

Elements of the operational work can be supported externally, but the accountability cannot be outsourced, and firms increasingly want the capability in-house; interim specialists bridge gaps while permanent capability is built.

How long does it take to develop CASS expertise?

A capable accountant can learn the operational discipline in months with the right exposure, but genuine oversight-level judgement — knowing how the rules apply to novel situations — takes years, which is why senior CASS professionals are so scarce.

Is CASS experience transferable across firm types?

Largely yes — the rules are the rules — though the emphasis shifts (custody-heavy versus client-money-heavy firms), and the best candidates adapt quickly to a new firm’s particular profile. Moving between CASS 7 and CASS 15 safeguarding takes more adjustment, not least because CASS 15 has no statutory trust.

Do safeguarding accountants earn the same as CASS accountants?

Broadly, yes. Safeguarding accountants at payments and e-money firms track the CASS Accountant and Senior CASS Accountant bands, with a premium for candidates who have already been through a safeguarding audit.
