“It's hard to quantify, right now. But at a guess, I'd say it's probably more than 50% faster, at times. It's literally that quick. We've found to be an essential practical tool. We're very satisfied.”

Customer due diligence measures meaning

What does Customer due diligence measures mean?
In practice, customer due diligence measures are the anti-money laundering (AML) checks carried out to identify and verify a customer and any beneficial owner, understand the purpose and intended nature of the business relationship or transaction, and conduct ongoing monitoring to keep information up to date and scrutinise dealings for consistency with the customer’s risk profile. The term is defined in legislation. In the UK (England & Wales, Scotland and Northern Ireland) it appears in the Money Laundering, Terrorist Financing and Transfer of Funds (Information on the Payer) Regulations 2017, which require a risk-based approach and set triggers for applying CDD, including when starting a business relationship, for certain occasional transactions, where suspicion arises, or where previous identification data is doubted. In higher-risk situations—such as dealings with Politically Exposed Persons (PEPs), customers from high‑risk third countries, or complex or unusual patterns—enhanced due diligence and enhanced ongoing monitoring must be applied. In Ireland, equivalent obligations apply to “designated persons” under the Criminal Justice (Money Laundering and Terrorist Financing) Acts 2010–2021. Across the UK and Ireland, the core features and practical expectations are broadly consistent, notwithstanding differences in terminology and supervisory guidance by sector.

UK Telecoms Security Act 2021: supplier obligations to public telecoms providers, contractual flow-downs, governance and training requirements, compliance timelines, and contract renegotiation

October 2022 saw the UK government introduce a new security framework via T(S)A 2021. This has since been bolstered by regulations that set out the precise security measures providers must undertake, together with a Code of Practice for telecoms providers that provides a good practice guide for effective telecoms security. The telecoms security rules present particular challenges for providers of public electronic communications networks or services (public telecoms providers), bringing extra compliance obligations, markedly increased risk and a series of key questions to address. Comprehensive due diligence should be carried out to identify the appropriate next steps to achieve compliance. Six key considerations Just because your business is not categorised as a Tier 1, 2 or 3 provider does not mean the rules will not affect you. Although suppliers to public telecoms providers are not directly regulated under the telecoms security rules, they will still be affected, as Tier 1 and Tier 2 providers are required contractually to flow down specific measures to their suppliers....

EU AML/CFT overhaul: EBA draft RTS on risk scoring, AMLA direct supervision thresholds, harmonised CDD and penalties, consultation feedback and 31 October 2025 submission deadline

When concluded, these standards will establish the compliance framework in full across the whole of the EU and are anticipated to deliver significant changes for all AML-obliged entities. The RTS will centre on four core areas of AML compliance: risk profile evaluation, the choice of entities to be directly overseen by the newly created AMLA, customer due diligence, and a new penalties regime. On 6 March 2025, the EBA opened a consultation on the draft RTS, during which stakeholders could submit feedback. It closed on 6 June 2025, and it is unclear whether, and in what manner, the EBA will reflect the input from stakeholders received and act on it in shaping the definitive RTS (EBA launches consultation on AML/CFT RTS, LNB News 06/03/2025 41). Regulatory steps After the AML package was published, the European Commission sent the EBA a call for advice. Such a call is a formal request from the Commission for technical input on drafting RTS and guidelines, which are needed to implement the regulations...
