What Is Organised Crime and How Are Cases Prosecuted in the UK?

Organised crime is one of the most serious categories of criminal offending in the UK. Cases are complex, investigations are lengthy, and the consequences of conviction — including lengthy prison sentences, confiscation of assets, and director disqualification — are severe. This guide explains what organised crime means in law, how investigations are conducted, how cases are prosecuted, and what the potential penalties are.

Our criminal defence solicitors in Bolton have experience representing individuals facing organised crime allegations at every stage — from the first contact with investigators through to Crown Court proceedings.


What Is Organised Crime?

There is no single statutory definition of “organised crime” in English law. The term is used to describe criminal activity carried out by groups of people working together in a coordinated and structured way, typically for financial gain. The Serious and Organised Crime Strategy published by the government defines an organised crime group as consisting of three or more people who work together on a continuing basis to commit serious offences.

Common types of organised criminal activity include:

  • Drug supply and trafficking — including county lines operations
  • People trafficking and modern slavery
  • Money laundering and the concealment of criminal proceeds
  • Firearms supply and distribution
  • Fraud, cybercrime, and financial crime at scale
  • Extortion, kidnapping, and blackmail
  • Organised robbery and acquisitive crime

Organised crime cases frequently overlap with other serious offences — particularly serious fraud and money laundering, which are often the mechanism by which organised crime proceeds are generated and concealed.


The Legal Framework: How Is Organised Crime Charged?

Because there is no single “organised crime” offence, prosecutors use a range of charges depending on the specific conduct alleged. The most commonly used are:

Conspiracy (Criminal Law Act 1977)

Conspiracy is the charge most frequently used in organised crime cases. It criminalises the agreement between two or more people to commit a criminal offence — regardless of whether the offence was actually carried out. A person can be convicted of conspiracy to supply drugs, conspiracy to commit robbery, or conspiracy to commit fraud, among many other variants.

The prosecution does not need to prove that each defendant personally carried out any specific criminal act — only that they were party to the agreement and knew its criminal purpose.

Participation in Organised Crime (Serious Crime Act 2015)

The Serious Crime Act 2015 created specific offences of participating in, supporting, or arranging organised crime groups. Under section 45, it is an offence to participate in the activities of an organised crime group while knowing or having reasonable cause to suspect that participating in those activities facilitates serious crime.

Proceeds of Crime Act 2002

Almost all organised crime prosecutions are accompanied by confiscation proceedings under the Proceeds of Crime Act 2002. Where a defendant is convicted, the prosecution will seek a confiscation order to recover the financial benefit derived from criminal conduct — even where that benefit has already been spent.


Who Investigates Organised Crime?

Organised crime investigations are led by a range of agencies depending on the nature and scale of the criminality:

The National Crime Agency (NCA) is the lead agency for the most serious and complex organised crime, including large-scale drug trafficking, people trafficking, and cybercrime with national or international reach.

Regional Organised Crime Units (ROCUs) — there are nine ROCUs across England and Wales — investigate organised crime at a regional level, working closely with local police forces.

Her Majesty’s Revenue and Customs (HMRC) leads on organised crime linked to tax fraud, VAT fraud, and excise duty evasion.

The Serious Fraud Office (SFO) investigates organised crime with a significant fraud or bribery dimension.

Local police forces investigate lower-level organised crime, including county lines drug supply, local gang activity, and acquisitive crime networks.

Investigations typically involve surveillance, telecommunications intercept evidence, undercover operations, and the analysis of financial data. The volume of material gathered in organised crime cases can be enormous — it is not unusual for a single case to involve hundreds of thousands of documents and hours of recorded communications.


How Are Organised Crime Cases Prosecuted?

Organised crime cases are almost always heard at the Crown Court. They are prosecuted by the Crown Prosecution Service (CPS) — typically the CPS Organised Crime Division — or in some cases by the SFO. Trials can be lengthy, often running for several weeks or months, and involve multiple defendants, highly technical evidence, and complex legal argument.

Joint Enterprise

A key feature of organised crime prosecutions is the doctrine of joint enterprise — which allows all members of a criminal group to be convicted for the actions of any individual member, provided they participated in the common purpose with knowledge of what was involved. This means that a person who played a peripheral role — perhaps handling money or providing logistical support — can be convicted of the same offence as the ringleader.

Cell Site and Communications Evidence

Modern organised crime prosecutions rely heavily on digital evidence — including call data records, cell site analysis showing the movements of mobile phones, encrypted messaging platforms, and social media. Our experienced criminal defence team works with expert witnesses to challenge this type of evidence where appropriate.

Confiscation Proceedings

After any conviction, the prosecution will apply for a confiscation order under POCA. This is a separate set of proceedings in which the court assesses the defendant’s benefit from criminal conduct and orders payment of an equivalent sum. Confiscation proceedings can be every bit as consequential as the trial itself and require specialist representation.


What Are the Penalties?

The penalties for organised crime offences are severe and reflect the seriousness with which the criminal justice system treats this type of offending:

OffenceMaximum sentence
Conspiracy to supply Class A drugsLife imprisonment
Participation in organised crime group5 years
People traffickingLife imprisonment
Money laundering14 years
Conspiracy to robLife imprisonment
Serious fraud10 years

In addition to imprisonment, defendants face unlimited fines, confiscation of assets, travel bans, and serious crime prevention orders — which can impose wide-ranging restrictions on a person’s activities even after release.

Frequently Asked Questions

Q: Can you be convicted of organised crime if you only played a small role?

Yes. Under the doctrine of joint enterprise, a person who participated in a criminal group with knowledge of its criminal purpose can be convicted of the same offences as more central participants. The prosecution does not need to prove that you personally carried out every act — only that you were part of the common criminal purpose.


Q: What is the difference between organised crime and conspiracy?

Conspiracy is a specific criminal charge — the agreement between two or more people to commit an offence. Organised crime is a broader term describing criminal activity carried out by structured groups. In practice, most organised crime prosecutions use conspiracy as the primary charge, alongside other specific offences depending on what the group was doing.


Q: What is a Serious Crime Prevention Order?

A Serious Crime Prevention Order (SCPO) is a civil order that can be imposed on conviction for a serious offence. It can restrict who a person associates with, what business activities they can carry out, and what communication devices they can use. Breach of an SCPO is itself a criminal offence carrying up to 5 years imprisonment.


Q: What happens to my assets if I’m convicted of an organised crime offence?

The prosecution will seek a confiscation order under the Proceeds of Crime Act 2002, requiring you to pay a sum equivalent to your benefit from criminal conduct. Assets may also have been restrained before conviction. Our Confiscation and Restraint Proceedings team can advise on challenging the scope of any confiscation order.


Q: How long do organised crime trials take?

It depends on the complexity of the case and the number of defendants. Simple cases may be listed for 2–4 weeks. Complex multi-handed cases with extensive surveillance and communications evidence can run for several months. The investigation before trial can take years.
