Compliance teams form a critical function at financial institutions and other regulated firms, tasked with undertaking AML checks to identify illicit activity and financial crime in order to safeguard businesses and mitigate risk.
In this article, you’ll find a practical anti-money laundering compliance checklist covering key areas, summarising good practice, helping firms meet compliance requirements, and strengthening confidence in operations.
What are AML checks?
An AML check is the process of verifying the identity of individuals or entities to help prevent money laundering, terrorist financing, and other financial crimes. The purpose of an AML check is to ensure businesses comply with regulatory requirements and protect the integrity of the financial system.
During an AML check, banks, payment providers, and other regulated entities carry out due diligence on customers. This usually involves collecting information and documentation to establish identity and assess the level of money laundering or financial crime risk they may present.
Why are AML checks important for compliance?
AML checks form a core part of detecting and preventing money laundering, fraud, and terrorist financing. They also help firms avoid the serious consequences of non-compliance.
A weak AML process can lead to severe outcomes, including regulatory fines, reputational damage, criminal investigation, and in some cases prosecution. In 2022, banks and other financial institutions were fined almost £4bn for AML compliance failings.
An Anti-Money Laundering compliance checklist
Conducting an AML check should be a thorough process. The steps below outline that process in detail. If you want a PDF version to keep on hand, download our AML checklist.
1. Streamline your Know Your Customer (KYC) procedures
As an AML compliance manager, you are likely familiar with Know Your Customer (KYC) procedures, but the challenge is making them both efficient and thorough. KYC is one of the most effective ways to identify potential risk early. Your procedures should focus on verifying customer identities and understanding the nature of their activity.
To streamline the process:
- Collect essential customer information such as full name, address, date of birth, and source of funds.
- Use automated identity verification tools to reduce manual error and speed up onboarding.
- Segment customers by risk so higher-risk individuals are subject to enhanced due diligence (EDD).
- Keep customer information up to date, particularly for high-risk clients or those whose profile has changed.
The goal is not just to verify identity at onboarding, but to maintain an accurate view of risk over time so suspicious activity can be identified early.
2. Adopt a risk-based approach for compliance
Not every customer presents the same level of risk, which is why a risk-based approach is essential. A blanket approach can waste resource or miss obvious warning signs.
To apply a risk-based approach:
- Assess customer risk levels based on factors such as geography, business activity, and source of wealth.
- Prioritise higher-risk customers through more frequent checks and enhanced due diligence.
- Use AML software to automate risk scoring and continuous monitoring.
This helps focus compliance effort where it is most needed.
3. Continuously monitor customer activities
AML compliance is not a one-time exercise. Ongoing monitoring is necessary to detect suspicious activity that may not be visible at onboarding.
To make monitoring effective:
- Use monitoring software to detect changes or suspicious indicators such as PEP status, sanctions matches, or adverse media.
- Set thresholds and alerts for high-risk events such as unusual transaction patterns or involvement with high-risk jurisdictions.
- Review flagged cases manually to decide whether escalation or external reporting is required.
Continuous monitoring improves your ability to detect suspicious activity in time.
4. Invest in regular employee training
Your employees are the first line of defence in identifying potential money laundering activity. Without proper training, critical red flags may be missed or mishandled.
To strengthen training:
- Provide onboarding training covering AML regulations, internal policy, and suspicious activity indicators.
- Run annual refresher training so employees stay aligned with changing regulation and emerging threats.
- Offer role-specific training for teams more likely to encounter risk, such as customer-facing or monitoring teams.
Good training builds a stronger culture of vigilance and reduces avoidable compliance failures.
5. Keep accurate and detailed records
Record-keeping is a core part of AML compliance. Firms need accurate, current records of customer data, risk assessments, and suspicious activity decisions.
Best practice includes:
- Maintaining detailed customer profiles including identity documents, risk ratings, and review history.
- Storing records securely using protected systems and appropriate access controls.
- Applying a retention policy that aligns with legal requirements, commonly five years for AML records.
Strong record-keeping helps demonstrate compliance and respond effectively to audits or investigations.
6. Strengthen internal controls and reporting mechanisms
AML compliance depends on a functioning internal framework of controls, responsibilities, escalation routes, and oversight.
To strengthen internal controls:
- Appoint a Money Laundering Reporting Officer (MLRO) to oversee suspicious activity reporting and compliance obligations.
- Create clear internal reporting procedures so employees know how to escalate concerns.
- Use automated tools to flag suspicious activity and alert compliance teams in real time.
- Review internal controls regularly to ensure they remain effective and aligned to regulation.
These controls make AML compliance part of normal operations rather than a reactive exercise.
7. Report suspicious activities promptly
Reporting suspicious activity is one of the most important parts of AML compliance. In the UK, firms are legally required to report relevant suspicion to the National Crime Agency (NCA).
To improve reporting:
- Develop a clear reporting process for identifying, escalating, and documenting suspicious activity.
- Train employees to recognise suspicious behaviour and escalate concerns appropriately.
- Use reporting tools that support accurate SAR submission and record retention.
Prompt, well-documented reporting reduces legal exposure and supports regulatory compliance.
8. Conduct regular audits and reviews
An AML programme is only effective if it is reviewed and improved on a regular basis. Audits help identify gaps and ensure controls remain fit for purpose.
To maintain a strong AML framework:
- Schedule regular audits of internal controls, KYC processes, and monitoring arrangements.
- Review compliance reports and SAR activity to spot trends and weaknesses.
- Stay informed on regulatory change through official updates, training, and industry events.
Ongoing review helps keep your AML framework aligned with current requirements and real-world risk.
Final thoughts on AML checks
Effective Anti-Money Laundering checks are not just a regulatory requirement. They are a necessary control for protecting businesses from financial crime and reputational harm.
Neglecting AML obligations can lead to substantial fines, enforcement action, and legal consequences. Firms need to treat AML compliance as a core operational discipline, not a box-ticking exercise.
By following a structured and practical AML checklist, businesses can strengthen controls, reduce risk, and demonstrate a credible commitment to compliance.
