CASS 15 Hub

From 7 May 2026, the new CASS 15 rules from the Financial Conduct Authority (FCA) will overhaul the safeguarding regime for payments firms and e-money firms.

As part of these changes, all authorised payments institutions (APIs) and e-money institutions (EMIs) will require an external audit of safeguarding practices each year.

For firms within the scope of CASS 15, the changes will be a huge step up from the current safeguarding requirements. Our specialists in safeguarding audits are here to ease the pressure, ensuring that your business is compliant with the CASS 15 regulations.

What do the new CASS 15 requirements include?

An annual external audit of safeguarding practices
More detailed record keeping and daily reconciliations
Maintaining a schedule of breaches
Regular client money and asset returns (CMAR)
Maintaining a CASS resolution pack

What should firms do to prepare for CASS 15?

As you get your new processes ready, two areas of particular importance are the CASS resolution pack and the schedule of breaches.

Daily reconciliations CASS resolution pack Schedule of breaches

One of the most fundamental operational shifts under CASS 15 is the requirement for daily reconciliations, both internal and external. EMIs must also maintain stronger books and records. This will ensure that safeguarding liabilities and funds can immediately be identified at any point in time, as well as allowing effective completion of regulatory returns.

In the event of insolvency, the pack will assist liquidators in the orderly wind-down of the firm. Key information in the pack would include clear directions to ensure the safe return of relevant funds.

The pack needs to be accurate, compliant and up to date: material changes should be made within five days. The pack is a window into your firm, so it’s important for you to make the right impression on the FCA from the start.

To help your business meet the FCA’s reporting requirements for breaches – in the annual safeguarding audit report, in the monthly CMAR, and as soon as you become aware of them – we recommend that your schedule of breaches report be continually reviewed. This will ensure that the audit report isn’t the first time that ‘Those Charged with Governance’ (e.g. your board of directors) are made aware of breaches identified internally.

The FCA will consider an empty schedule of breaches as more of a red flag than one with breaches. This is because an empty schedule would indicate that your firm’s systems and controls are not effective enough to identify breaches.

Under CASS, any discrepancy at all must be reported, along with the remedial action taken.

What is CASS 15?

CASS 15 is a new section of the FCA’s Client Assets Sourcebook that sets out enhanced safeguarding rules for e-money institutions and payment firms to better protect customer funds.

What is CASS 15 in simple terms?

CASS 15 is a set of FCA rules that require payment and e-money firms to properly protect customer money, with clearer processes, stronger oversight, and independent audits.

Why is the FCA introducing CASS 15?

The FCA is introducing CASS 15 to improve consumer protection, increase transparency, and address weaknesses in how some firms safeguard customer funds.

When does CASS 15 come into force in the UK?

CASS 15 is expected to come into force in May 2026. Firms should begin preparing well in advance to ensure compliance.

Which firms need to comply with CASS 15?

CASS 15 applies to UK e-money institutions (EMIs), authorised payment institutions (APIs), and some small payment institutions (SPIs) that safeguard customer funds.

What is CASS 15 safeguarding?

CASS 15 safeguarding refers to the rules and processes firms must follow to protect customer funds, including segregation, governance, controls, and audit requirements.

What are the key CASS 15 requirements?

Key requirements include stronger governance, clear safeguarding policies, segregation of funds, regular reconciliations, enhanced record-keeping, and mandatory safeguarding audits.

How is CASS 15 different from current FCA safeguarding rules?

CASS 15 introduces a more structured and auditable framework, with clearer rules, stronger governance expectations, and mandatory audits, replacing the more principles-based approach.

What does CASS 15 mean in practice for firms?

In practice, firms will need to formalise and strengthen safeguarding frameworks, improve documentation, enhance controls, and prepare for independent audits.

What changes will firms need to make under CASS 15?

Firms may need to update policies, strengthen governance, improve reconciliations, enhance documentation, and ensure full audit readiness.

What is a CASS 15 audit?

A CASS 15 audit is an independent review of a firm’s safeguarding arrangements to ensure customer funds are properly protected and FCA requirements are met.

Do EMI firms need a safeguarding audit under CASS 15?

Yes. E-money institutions will be required to undergo formal safeguarding audits under CASS 15.

How do you prepare for a CASS 15 audit?

Preparation includes conducting a gap analysis, reviewing controls, strengthening governance, documenting processes, and testing audit readiness.

How long does it take to prepare for CASS 15 compliance?

Preparation can take several months depending on the complexity of the firm’s safeguarding arrangements and existing maturity.

How much work is required to become CASS 15 compliant?

The level of effort varies. Firms with less developed safeguarding frameworks may require significant remediation, while more mature firms may need targeted improvements.

When should firms start preparing for CASS 15?

Firms should start as early as possible to allow time for gap analysis, implementation, and audit readiness ahead of the 2026 deadline.

Do firms need to act now on CASS 15?

Yes. Early action is recommended, as implementing governance, control, and audit changes can take significant time.

What are safeguarding reconciliations and why are they important?

Safeguarding reconciliations ensure that customer funds held match internal records. They are critical for demonstrating that funds are properly protected.

What are the main safeguarding methods under FCA rules?

Firms typically safeguard funds through segregation in designated accounts or through insurance or comparable guarantees.

What are the FCA safeguarding rules for payment institutions?

FCA rules require firms to protect customer funds, maintain accurate records, perform reconciliations, and ensure funds are accessible if the firm fails.

What are the biggest risks under CASS 15?

Key risks include weak governance, poor documentation, failed audits, inaccurate reconciliations, and increased FCA scrutiny.

What happens if a firm does not comply with CASS 15?

Non-compliance may result in FCA enforcement action, financial penalties, reputational damage, and operational restrictions.

What happens if you fail a CASS 15 audit?

Failing an audit can lead to remediation requirements, increased regulatory scrutiny, and potential enforcement action.

Will CASS 15 increase regulatory scrutiny?

Yes. CASS 15 is expected to increase FCA oversight, with greater focus on governance, documentation, and audit evidence.

Do I already comply with CASS 15 requirements?

Most firms will not fully comply yet and will need to enhance governance, controls, and documentation to meet the new standards.

Can smaller firms take a simplified approach to CASS 15?

While proportionality may apply, all firms must still meet core safeguarding requirements and demonstrate effective protection of customer funds.

How can firms assess their readiness for CASS 15?

Firms can conduct a gap analysis of their safeguarding framework, controls, governance, and documentation against CASS 15 requirements.

How can firms ensure CASS 15 compliance?

Firms should strengthen safeguarding frameworks, improve controls, prepare for audit, and seek expert advice where needed.

Who can help with CASS 15 compliance and audits?

Specialist advisers such as BKL can support with readiness assessments, gap analysis, audit preparation, and ongoing compliance.
