Professional services firms occupy a unique and increasingly scrutinised position within the UK anti-money laundering framework. Whether your firm provides accountancy services, bookkeeping support, tax advice, legal services, corporate structuring, trust administration, company formation, nominee arrangements, or wider fiduciary services, your business may sit directly at the point where criminal actors attempt to legitimise illicit wealth, obscure beneficial ownership, move assets across jurisdictions, or create structures designed to frustrate transparency.

Unlike banks, payment institutions, or other financial institutions that typically encounter funds once they are already in circulation, professional services firms are often engaged much earlier in the lifecycle of a transaction or structure. This places accountants, solicitors, tax advisers, and trust and company service providers at the front line of the UK’s anti-money laundering and counter-terrorist financing regime.

At The AML Practice, we help professional services firms design, implement, and strengthen practical AML and CTF frameworks that are proportionate, regulator-ready, and capable of standing up to supervisory scrutiny.

The UK Money Laundering Regulations capture a broad range of professional service providers. Depending on the nature of your services, your business may fall within scope if you provide services such as:

• accountancy or bookkeeping services 
• tax advice or tax compliance services 
• audit or assurance services 
• insolvency services 
• legal advice connected to financial or property transactions 
• trust administration services 
• company formation services 
• nominee director or nominee shareholder services 
• registered office services 
• corporate secretarial services 
• partnership or trust structuring services 
• fiduciary or estate administration services 

Many firms do not initially appreciate that seemingly routine services—such as bookkeeping, tax planning, company secretarial work, or registered office services—can bring them directly within scope of the UK AML regime.

Professional services firms are often viewed by criminal actors as trusted gateways into the legitimate economy. A respected accountant, solicitor, or corporate services provider can provide an appearance of legitimacy, credibility, and commercial substance that helps disguise illicit activity.

Criminals may seek to use professional advisers to:

• establish complex ownership structures 
• conceal beneficial ownership 
• move funds between jurisdictions 
• create trusts or holding structures 
• acquire property or businesses 
• introduce funds into regulated channels 
• create layers of legal separation between assets and true ownership 
• obtain professional opinions that lend credibility to suspicious transactions 

A weak AML framework can unintentionally allow a legitimate professional practice to become part of a money laundering or terrorist financing scheme.

One of the most common typologies involves attempts to obscure the identity of the ultimate beneficial owner through layers of corporate entities, trusts, partnerships, nominees, or overseas holding structures. Warning signs may include:

• unnecessarily complex ownership arrangements 
• offshore entities with no obvious commercial rationale 
• multiple ownership changes in a short period 
• nominee directors or shareholders with limited apparent involvement 
• reluctance to disclose ownership information 
• inconsistent corporate documentation 

Professional services firms are expected to look beyond surface-level documentation and understand who ultimately owns or controls the client.

Trusts, foundations, partnerships, and corporate vehicles can all serve legitimate purposes. However, they may also be used to obscure ownership, separate assets from beneficial control, or move wealth across borders. Common indicators include:

• structures involving multiple jurisdictions 
• disconnected beneficiaries or controllers 
• frequent amendments to trust arrangements 
• unusual voting or control rights 
• structures with no clear tax, legal, or commercial rationale 

Supervisors increasingly expect firms to challenge structures that appear unnecessarily complex or commercially unusual.

Clients may present apparently credible explanations for wealth or funding that do not stand up to independent scrutiny. Examples may include:

• unsupported inheritance claims 
• unverifiable overseas business proceeds 
• unexplained property sales 
• inconsistent tax records 
• wealth levels inconsistent with occupation or profile 
• reluctance to provide documentary evidence 

Professional firms are expected to apply appropriate challenge where explanations do not align with the known profile of the client.

Law firms, accountants, and trust providers involved in property acquisitions, restructurings, mergers, acquisitions, or asset transfers may be exposed to layering activity. Common warning signs include:

• unexplained urgency 
• third-party funding arrangements 
• unusual valuation discrepancies 
• complex payment structures 
• funds moving through multiple jurisdictions 
• instructions inconsistent with the client’s known profile 

Legal professionals in particular may face attempts by clients to use client accounts as quasi-banking facilities rather than for legitimate legal services. Indicators may include:

• funds entering and leaving rapidly 
• payments unrelated to the underlying matter 
• repeated third-party payments 
• little genuine legal work being undertaken 
• instructions that fall outside the agreed retainer 

Supervisors are increasingly focused on misuse of professional client accounts.

Professional services firms increasingly encounter cross-border clients, politically exposed persons, and jurisdictions associated with elevated corruption, sanctions, or terrorist financing risk.

Risk indicators may include:

• ownership links to sanctioned jurisdictions 
• politically exposed beneficial owners 
• adverse media findings 
• unexplained payment routing 
• reluctance to disclose overseas relationships 
• opaque ownership chains involving multiple jurisdictions 

Supervision depends on the nature of your business, your services, and whether you belong to a recognised professional body.

Accountancy practices, bookkeeping firms, tax advisers, and certain audit firms may be supervised by HM Revenue & Customs or by a recognised professional body. This may include organisations such as:

• ICAEW 
• ACCA 
• AAT 
• ICAS 
• other recognised professional body supervisors 

Where HMRC is the supervisory authority, firms must register before carrying out regulated activity and remain subject to ongoing supervision. HMRC may carry out:

• desktop compliance reviews 
• information requests 
• onsite inspections 
• thematic reviews 
• enforcement investigations 

Most solicitors’ firms and independent legal professionals are supervised by their legal sector supervisor. This may include:

• Solicitors Regulation Authority 
• Council for Licensed Conveyancers 
• Bar Standards Board 
• other legal professional supervisors 

Legal sector supervisors increasingly focus on client account controls, beneficial ownership verification, sanctions compliance, and source of funds documentation.

Trust and company service providers that are not otherwise supervised by another professional body are often directly supervised by HM Revenue & Customs. This may include firms providing:

• company incorporation 
• registered office services 
• nominee arrangements 
• directors’ services 
• trust administration 
• fiduciary services 

These businesses are frequently regarded as higher risk due to their ability to create and administer legal structures.

Regardless of your supervisory authority, expectations are broadly consistent across the sector.

Firms must maintain a documented risk assessment that identifies and evaluates the money laundering and terrorist financing risks associated with:

• clients 
• products and services 
• delivery channels 
• jurisdictions 
• transaction types 
• intermediaries 

This document should reflect how your business actually operates rather than generic template language.

Supervisors expect firms to maintain clear, up-to-date written policies covering:

• customer due diligence 
• enhanced due diligence 
• beneficial ownership verification 
• source of funds 
• source of wealth 
• sanctions screening 
• PEP screening 
• ongoing monitoring 
• suspicious activity reporting 
• record retention 
• governance and escalation 

Policies should be practical, implemented, and understood by staff.

Supervisors expect firms to understand:

• who the client is 
• who ultimately owns or controls them 
• why the structure exists 
• where funds originate 
• whether the activity makes commercial sense 

CDD should not be treated as a box-ticking exercise.

Due diligence does not end at onboarding. Firms should monitor:

• ownership changes 
• unusual instructions 
• changes in client behaviour 
• changes in transaction patterns 
• emerging adverse media 
• changes in jurisdictional exposure 

Partners, directors, MLROs, fee earners, and support staff should receive regular AML and CTF training appropriate to their responsibilities.

Supervisors will often request evidence of training during inspections.

Firms must maintain clear internal escalation processes and, where appropriate, submit reports to the National Crime Agency.

Supervisors often review not only whether reports are submitted, but how decisions are documented.

Supervisors increasingly expect evidence that senior management actively oversees AML compliance. This may include:

• compliance reporting 
• management information 
• file reviews 
• documented challenge 
• remediation tracking 
• independent assurance 

In our experience, common weaknesses identified during HMRC and professional body reviews include:

• outdated business-wide risk assessments 
• generic template policies 
• weak beneficial ownership verification 
• insufficient source of wealth enquiries 
• poor sanctions screening evidence 
• incomplete matter risk assessments 
• inconsistent file reviews 
• weak internal escalation records 
• poor training records 
• insufficient partner oversight 

These weaknesses may exist for years before being identified by a supervisor.

AML compliance is not simply an administrative requirement. It can directly determine whether your firm is allowed to continue operating.

Where HMRC or your professional body identifies serious weaknesses, enforcement action may begin with remediation notices, enhanced supervision, information requests, or thematic reviews. However, where deficiencies are serious, repeated, systemic, or left unaddressed, enforcement can become significantly more serious. Regulatory action may include:

• formal remediation notices 
• enhanced supervisory monitoring 
• financial penalties 
• disciplinary proceedings 
• public enforcement action 
• suspension of AML registration 
• cancellation of AML registration 
• prohibition of partners, directors, owners, or senior managers 

For many firms, loss of AML supervision means loss of the ability to legally provide regulated services. In practical terms, this may result in:

• immediate inability to onboard new clients 
• loss of banking facilities 
• professional indemnity concerns 
• reputational damage 
• partner departures 
• loss of enterprise value 
• inability to complete existing engagements 
• in serious cases, closure of the business altogether 

Put simply, if your AML framework fails, your business may fail with it.

We support professional services firms with:

• HMRC registration support 
• business-wide risk assessments 
• firm-wide risk assessments 
• AML policy drafting and remediation 
• independent AML audits 
• file reviews 
• MLRO support 
• partner and staff training 
• supervisory visit preparation 
• remediation following regulatory findings 
• ongoing retained compliance support
