There are two types of accounting practices right now. Those that updated their firm-wide risk assessment after September 2022 to include counter proliferation financing as a standalone section. And those that didn’t.
The second group is non-compliant today.
This guide covers what Counter Proliferation Financing is, whether your firm is in scope, how it differs from your existing AML obligations, what the red flags look like in practice, and what you need to update to close the gap.
What Is Counter Proliferation Financing & Why It Matters to UK Accountants?
Counter proliferation financing is the measures taken to disrupt and prevent funding of activities related to the acquisition, development, manufacture, transportation, or possession of weapons of mass destruction. That covers nuclear, chemical, and biological weapons, their delivery systems, and related materials, including dual-use technologies.
The Financial Action Task Force defines it as raising, moving, or making available funds for WMD proliferation purposes, including delivery systems and related materials.
As a UK accountant, you operate as a Designated Non-Financial Business or Profession (DNFBP), which places you within the same regulatory framework as financial institutions for AML purposes. When the Money Laundering and Terrorist Financing (Amendment) (No. 2) Regulations 2022 came into force in September 2022, counter proliferation financing (CPF) became a standalone legal obligation for all DNFBPs, including accountants, bookkeepers, and tax advisers performing specific activities.
Does Counter Proliferation Financing Apply to Your Firm?
The short answer is yes. Regulation 18A of the Money Laundering and Terrorist Financing (Amendment) (No. 2) Regulations 2022 requires all relevant persons to take appropriate steps to identify, evaluate, and mitigate the risks of proliferation financing to which their business is subject. That includes accountants, bookkeepers, and tax advisers operating within the MLR framework.
What the regulations vary is not who is obligated, but the extent of what’s required. In carrying out your risk assessment, you must take into account the Treasury’s proliferation financing risk assessment under Regulation 16A, alongside risk factors specific to your own firm:
- Customers
- Countries or geographic areas in which it operates
- Products or services
- Transactions
- Delivery channels
These five factors are the lens through which your counter proliferation financing exposure should be assessed. A firm with clients in international trade, manufacturing, or specialist technology carries a different risk profile from one whose client base is entirely domestic and service-based. The same CPF obligation applies to both. What proportionate compliance looks like for each will differ.
How Is Proliferation Financing Different from Money Laundering & Terrorist Financing?
The funds used for proliferation financing can be entirely clean in origin. That’s the critical distinction, and it’s the one that breaks the standard AML instinct of following dirty money.
In money laundering, the problem is the source of funds. Criminals need to clean the proceeds of crime and move them into the legitimate financial system. In terrorist financing, funds can be legitimate or illegitimate in origin, but the end use is violence. In proliferation financing, both the source and the initial movement of funds can look completely normal. The problem is what the money ultimately buys: materials, technology, or expertise that feeds a weapons programme.
This matters directly for how you approach risk assessment. Your existing AML controls are built around identifying suspicious sources and unusual transaction patterns. counter proliferation financing asks you to look beyond that. The client may be entirely credible. The transaction may appear routine. The red flag is the destination, the goods, or the end user. Not the money itself.
That’s why the 2022 regulations require a standalone CPF section in your firm-wide risk assessment rather than absorbing it into your existing AML framework.
What Are Dual-Use Goods & Why Do They Matter to Accountants?
Dual-use goods are physical items with legitimate civilian applications that can be diverted for weapons programmes. The Money Laundering and Terrorist Financing (Amendment) (No. 2) Regulations 2022 define them specifically as items listed in Annex I of the Dual-Use Regulation. The same regulation covers dual-use technology, which includes anything in that Annex described as software or technology, including items transmitted electronically, by fax, or by telephone.
Both dual-use goods and dual-use technology fall within the CBRN framework, around which the counter proliferation financing regulations are built.
The controlled categories under the Dual-Use Items (Export Control) Regulations include:
- Chemicals and materials
- Microorganisms and toxins
- Telecommunications equipment
- Marine equipment
- Aircraft and propulsion systems
If you have a client in any of these categories whose goods or technology could connect to the development, production, handling, or storage of chemical, biological or nuclear weapons, their CPF risk profile is materially different to a client running a domestic service business, even if their standard AML profile looks identical. Your due diligence needs to account for what they produce, export, or ship.
What Geographic & Country-Level Risks Should UK Accountants Be Aware Of?
Geography is a standalone counter proliferation financing risk factor under Regulation 18A of the Money Laundering and Terrorist Financing (Amendment) (No. 2) Regulations 2022, which requires relevant persons to take into account the countries or geographic areas in which they operate when carrying out their proliferation financing risk assessment.
Certain countries are subject to targeted financial sanctions specifically for WMD-related activity. North Korea and Iran are the two most consistently identified proliferation concerns, with multiple UN Security Council resolutions mandating member states to freeze assets and block transactions connected to proliferation actors in those jurisdictions.
The UK’s National Risk Assessment of Proliferation Financing identified three domestic vulnerabilities:
- The country’s openness to foreign investment
- The ease with which companies can be formed
- The strength of its financial sector
For proliferators seeking to establish seemingly legitimate structures, those three factors make the UK an attractive jurisdiction.
Shell companies, nominee shareholders, and new company formations with cross-border ownership connected to high-risk jurisdictions all require heightened counter proliferation financing scrutiny. If a client’s ownership structure involves those jurisdictions, or if transactions connect to countries with known proliferation associations, your risk assessment needs to reflect that explicitly.
What Are UK Accountants' Legal CPF Obligations Under the Money Laundering Regulations?
The 2022 amendment created six distinct obligations. Each applies to your firm if you’re carrying out Schedule 1 activities.
What Are the Red Flags for Proliferation Financing That Accountants Should Recognise?
Counter proliferation financing (CPF) red flags fall into three clusters.
How Do You Integrate CPF Into Your Firm's Existing AML Framework?
Counter proliferation financing sits inside your existing risk-based approach. The question isn’t whether to rebuild your framework. It’s which specific parts need updating.
What Does the FCA's Takeover of AML Supervision Mean for CPF Compliance?
The FCA is replacing Professional Body Supervisors as the AML supervisor for accountancy firms. Once the legislation passes, all firms currently supervised by a PBS will move to FCA supervision instead.
The new FATF methodology, which the UK’s next Mutual Evaluation in 2028 will be assessed against, places significantly greater emphasis on effectiveness rather than documented procedures. Having a counter proliferation financing policy on paper isn’t sufficient. The FCA will assess whether your controls are actually working in practice.
The HM Treasury AML Supervision Report 2024-25 confirms that the most common compliance failures identified across supervised firms include inadequate documented policies and procedures, inadequate client risk assessment, and failure to tailor policies to the individual firm. These are precisely the gaps that a weak CPF framework produces.

Conclusion
Counter proliferation financing (CPF) has been a standalone legal obligation since September 2022. Three things make it genuinely different from standard AML:
- the source of funds can be entirely clean;
- dual-use goods create risk exposure standard CDD isn’t designed to catch;
- and geography carries standalone significance.
Your firm-wide risk assessment needs a dedicated CPF section, your client risk classifications need to account for sector and geography, your screening tools need to cover the right sanctions lists, and your staff need CPF-specific training.
The FCA’s incoming supervision will assess whether controls work, not just whether they exist on paper. The firms that close their counter proliferation financing gaps now won’t be closing them under a more demanding supervisor later.
Frequently Asked Questions (FAQs)
Counter proliferation financing refers to the measures taken to disrupt and prevent the funding of activities connected to the development, manufacture, acquisition, or transfer of weapons of mass destruction. For accountants, it sits alongside money laundering and terrorist financing as a distinct compliance obligation under the Money Laundering Regulations.
No. Money laundering conceals the illegal origin of funds. In proliferation financing, the funds can be entirely legitimate in origin. The problem is what they buy or enable. That distinction requires a separate risk assessment, separate red flags, and a separate section in your compliance framework.
Proliferation financing typically moves through three stages: raising funds to support proliferation activities, disguising those funds to obscure their destination and purpose, and procuring proliferation-sensitive materials or technology. Unlike money laundering, the funds are deployed toward acquiring weapons-related goods or capabilities rather than returned to the source.
For accountants, counter proliferation strategies operate through the AML framework: conducting a standalone counter proliferation financing risk assessment, screening clients against UN and EU sanctions lists, applying CPF-aware due diligence to clients in high-risk sectors, filing SARs where there are reasonable grounds for suspicion, and maintaining CPF-specific staff training.
It is mandatory for accountants performing specific activities under the Money Laundering Regulations, including managing client money, forming companies, and handling asset transfers. Practitioners whose work falls entirely outside those activities carry a lower direct obligation, though professional standards still require you to ensure your services are not being misused.
UN and EU sanctions lists are the mandatory minimum under UK law. Screening against OFAC lists is not legally required but is recognised as best practice and has been observed as a feature of well-run CPF compliance frameworks.
Dual-use goods are physical items listed in Annex I of the Dual-Use Regulation with legitimate civilian applications that can be diverted for weapons programmes. Dual-use technology covers software and technology in the same Annex. Controlled categories include chemicals and materials, microorganisms and toxins, telecommunications equipment, marine equipment, and aircraft and propulsion systems.
Both can involve legitimate sources of funds. The distinction is purpose. Terrorist financing funds violent acts. Proliferation financing funds the acquisition, development, or storage of weapons of mass destruction. Both sit alongside money laundering as separate obligations under the Money Laundering Regulations, each requiring its own risk assessment and controls.
Your firm is non-compliant with the Money Laundering and Terrorist Financing (Amendment) (No. 2) Regulations 2022, which came into force on 1 September 2022. The HM Treasury AML Supervision Report 2024-25 identifies inadequate risk assessments and untailored policies as among the most common findings in enforcement action across supervised firms.
