Money laundering is one of the most serious financial crimes under UK law, carrying penalties of up to 14 years in prison. Yet it is also one of the most widely misunderstood — many people who find themselves under investigation did not set out to launder money and may not even have realised that what they were doing fell within the legal definition. This guide explains what money laundering is, what the specific offences are, and what the consequences of a conviction can mean.
Our criminal defence solicitors in Bolton represent individuals and businesses facing money laundering allegations at every stage of investigation and prosecution.
What Is Money Laundering?
Money laundering is the process by which the proceeds of criminal activity are made to appear legitimate. The term comes from the idea of “cleaning” dirty money — taking funds derived from crime and passing them through financial transactions or commercial activity so that they appear to have come from a lawful source.
In UK law, money laundering is not a single offence. It is a cluster of offences under Part 7 of the Proceeds of Crime Act 2002 (POCA), which criminalise a wide range of conduct connected to the handling, concealing, and transferring of criminal property.
Critically, the criminal property does not have to originate from a serious or organised crime. Any money or property that represents the proceeds of any criminal offence — including relatively minor offences — can constitute criminal property for the purposes of POCA.
The Three Stages of Money Laundering
Money laundering is typically described as occurring in three stages, though in practice these can overlap or be compressed into a single transaction:
Placement — introducing criminal proceeds into the financial system. This might involve depositing cash into bank accounts, purchasing assets, or using money service businesses to transfer funds.
Layering — separating the funds from their criminal origin through a series of complex transactions designed to obscure the audit trail. This can involve multiple transfers between accounts, jurisdictions, and entities.
Integration — reintroducing the laundered funds into the legitimate economy in a form that appears clean — for example through property purchases, business investments, or luxury goods.
What Are the Money Laundering Offences Under POCA?
Section 327 — Concealing Criminal Property
This offence is committed where a person conceals, disguises, converts, transfers, or removes criminal property from England and Wales. It is broad in scope and does not require any sophisticated arrangement — a single transaction involving criminal proceeds can be sufficient.
Maximum sentence: 14 years imprisonment.
Section 328 — Arrangements
This is one of the most widely charged money laundering offences. It is committed where a person enters into or becomes concerned in an arrangement which they know or suspect facilitates the acquisition, retention, use, or control of criminal property by or on behalf of another person.
The width of this offence is significant. It can capture professional advisers, business partners, family members, and others who become involved in arrangements without necessarily being the primary beneficiary. Knowledge or suspicion at the time of entering the arrangement is required — but suspicion is a low threshold.
Maximum sentence: 14 years imprisonment.
Section 329 — Acquisition, Use and Possession
This offence is committed where a person acquires, uses, or has possession of criminal property. It captures anyone who receives, uses, or holds property that they know or suspect represents the proceeds of crime — even if they played no role in generating those proceeds.
A statutory defence is available where adequate consideration was given for the property — meaning the property was received as part of a genuine transaction at fair value.
Maximum sentence: 14 years imprisonment.
The Importance of Knowledge and Suspicion
All three principal POCA offences require either knowledge or suspicion that the property in question is criminal property. This is an important distinction from some other serious offences — the prosecution does not need to prove that you knew the specific crime from which the property derived, only that you knew or suspected it represented the proceeds of some criminal conduct.
Suspicion is deliberately set as a low threshold in money laundering law. Courts have held that suspicion does not require certainty or even probability — it is a state of mind where a person thinks there is a possibility, which is more than fanciful, that the relevant facts exist.
This means that turning a blind eye to obvious indicators — refusing to ask questions that might reveal the source of funds — is unlikely to provide a defence if those indicators were present and obvious.
Failure to Disclose — The Regulated Sector
There is a separate category of money laundering offences that applies specifically to individuals working in the regulated sector — which includes banks, accountants, solicitors, estate agents, and other professional services firms.
Section 330 — Failure to Disclose (Regulated Sector)
Where a person working in the regulated sector knows, suspects, or has reasonable grounds to know or suspect that another person is engaged in money laundering, they commit an offence if they fail to make a Suspicious Activity Report (SAR) to the National Crime Agency as soon as practicable.
Unlike the principal offences, this offence can be committed on the basis of reasonable grounds to suspect — an objective test rather than a subjective one. A professional cannot argue they simply did not think about it if a reasonable person in their position would have been suspicious.
Maximum sentence: 5 years imprisonment.
Section 333A — Tipping Off
It is also an offence to tip off a person who is or may be under investigation for money laundering, where doing so is likely to prejudice any investigation. This offence is particularly relevant to professionals and advisers who may inadvertently warn a client that a SAR has been filed.
Maximum sentence: 2 years imprisonment.
How Are Money Laundering Cases Investigated?
Money laundering investigations are typically led by one of several agencies depending on the nature and scale of the underlying criminality:
- The National Crime Agency (NCA) — leads on the most serious and organised money laundering, particularly where there is a link to serious organised crime
- HMRC — investigates money laundering linked to tax evasion and VAT fraud
- The Serious Fraud Office (SFO) — where money laundering forms part of a broader serious fraud investigation
- The Financial Conduct Authority (FCA) — regulated sector failures and financial market misconduct
- The police — regional organised crime units and economic crime departments handle the majority of money laundering cases at a local level
Investigations typically begin with financial intelligence — analysis of bank records, transaction patterns, and suspicious activity reports filed by regulated firms. They often result in account freezing orders, restraint orders, or arrest and interview under caution at an early stage.
What Happens After a Money Laundering Charge?
Money laundering cases are generally heard at the Crown Court given the seriousness of the offences and the sentencing powers required. Prosecutions can involve large volumes of financial evidence, expert witnesses, and complex legal argument about the source and nature of the alleged criminal property.
Alongside the criminal proceedings, the prosecution will almost invariably seek a confiscation order under POCA after any conviction. This is a separate process in which the court assesses the benefit derived from criminal conduct and orders payment of a sum equivalent to that benefit — regardless of whether the money has been spent. Confiscation proceedings require specialist representation in their own right and can be every bit as consequential as the criminal trial itself.
What Are the Penalties for Money Laundering?
| Offence | Maximum sentence |
|---|---|
| Section 327 — Concealing | 14 years |
| Section 328 — Arrangements | 14 years |
| Section 329 — Acquisition/possession | 14 years |
| Section 330 — Failure to disclose | 5 years |
| Section 333A — Tipping off | 2 years |
In addition to imprisonment, defendants face unlimited fines, confiscation orders under POCA, director disqualification, and the destruction of professional reputation. For those in regulated professions, a conviction will almost certainly result in loss of professional registration.
Common Defences in Money Laundering Cases
Money laundering prosecutions are not always straightforward. Defences that may be available depending on the circumstances include:
Lack of knowledge or suspicion — if you genuinely did not know and had no reasonable grounds to suspect that the property was criminal in origin, the principal offences under sections 327–329 cannot be made out. This is a question of fact for the jury.
Adequate consideration — for section 329 (acquisition, use, and possession), a defence exists where adequate consideration was given in exchange for the property in a legitimate transaction.
Authorised disclosure — commonly known as the “consent defence”. Where a person makes a disclosure to the NCA before entering into a transaction and obtains consent, they have a defence even if the property turns out to be criminal. This defence is complex and requires careful legal advice before any disclosure is made.
No underlying criminal property — if the prosecution cannot prove that the property in question actually represents the proceeds of criminal conduct, the offence cannot be established.
What Should You Do If You Are Under Investigation?
If you are under investigation for money laundering — whether because your bank account has been frozen, you have been contacted by investigators, or you have been arrested — the most important step is to take specialist legal advice immediately.
Do not speak to investigators without a solicitor present. Do not attempt to move funds or assets. Do not contact others who may be involved in the investigation. Exercise your right to legal representation from the very first moment.
Our money laundering solicitors will advise you on your position, attend any interview with you, and build the strongest possible defence from the earliest stage of proceedings.

Frequently Asked Questions
Q: What counts as money laundering in the UK?
Under the Proceeds of Crime Act 2002, money laundering covers concealing, disguising, converting, transferring, or removing criminal property (section 327); entering into arrangements that facilitate the acquisition or control of criminal property by another (section 328); and acquiring, using, or possessing criminal property (section 329). The property does not have to come from serious organised crime — the proceeds of any criminal offence can constitute criminal property.
Q: Do you have to know the money is criminal to be guilty of money laundering?
Not fully. The offences require knowledge or suspicion that the property represents the proceeds of criminal conduct — not certainty. Suspicion is a low threshold and can be inferred from the circumstances. Deliberately avoiding questions that would reveal the truth is unlikely to provide a defence if obvious indicators were present.
Q: What is the maximum sentence for money laundering in the UK?
The principal money laundering offences under sections 327, 328, and 329 of POCA all carry a maximum sentence of 14 years imprisonment. In practice, sentences depend on the scale of the laundering, the defendant’s role, and any mitigating factors.
Q: Can you be convicted of money laundering if you did not commit the underlying crime?
Yes. The money laundering offences are entirely separate from the underlying predicate offence. You can be convicted of money laundering even where you played no part in generating the criminal proceeds — for example if you received, held, or transferred money knowing or suspecting it came from crime.
Q: What is a Suspicious Activity Report (SAR)?
A SAR is a report filed with the National Crime Agency by a regulated sector professional who knows, suspects, or has reasonable grounds to suspect that a transaction or activity involves money laundering or terrorist financing. Filing a SAR can provide a defence against prosecution for the person who filed it and is a legal obligation in the regulated sector.
Q: What happens to assets in a money laundering case?
Assets may be frozen at an early stage through an account freezing order or restraint order under POCA, often before any charge is brought. After conviction, the prosecution will seek a confiscation order requiring payment of a sum equivalent to the defendant’s benefit from criminal conduct.
