Money Laundering Regulations (MLR) definition and meaning | AML glossary

What are money laundering regulations (MLR)? Definition and AML compliance meaning.

Money laundering regulations (MLR) definition: What it means in AML compliance.

The Money Laundering Regulations (MLR) are a set of UK legal requirements designed to prevent criminals from disguising the origins of illicit funds. These regulations apply to firms across financial services, legal, accountancy, estate agency, and other high-risk sectors. The current framework is set out in the Money Laundering, Terrorist Financing and Transfer of Funds (Information on the Payer) Regulations 2017, with several amendments introduced since to reflect evolving threats and EU directives.

Examples of money laundering regulations.

The UK’s AML regime includes several detailed rules designed to prevent the misuse of the financial system. Examples include:

  • Regulation 27 – Customer Due Diligence (CDD): Requires firms to verify the identity of customers and beneficial owners before establishing a business relationship or carrying out transactions.
  • Regulation 33 – Enhanced Due Diligence (EDD): Obligates firms to apply additional checks when dealing with high-risk clients, such as politically exposed persons (PEPs) or customers from high-risk third countries.
  • Regulation 28 – Ongoing Monitoring: Mandates that firms continuously monitor business relationships, ensuring customer information is current and transactions align with the customer’s risk profile.
  • Regulation 21 – Risk Assessments: Requires firms to carry out a written risk assessment identifying and assessing the risks of money laundering and terrorist financing they face.
  • Regulation 40 – Record-Keeping: Firms must retain identity checks, risk assessments, and transaction records for at least five years after the end of a client relationship.
  • Regulation 47 – Policies, Controls and Procedures: Requires firms to implement appropriate internal controls to manage and mitigate money laundering risk.

These regulations form the foundation of a robust AML framework and are enforced by supervisory bodies such as the Financial Conduct Authority (FCA) and HMRC.
