What Conspiracy Charges Mean, What Can Go Wrong and Why Early Legal Advice Is Important
13/08/2026
By David Woods and Liam Ferris, Criminal Law Partners at JR Levins
A conspiracy charge is one of the most serious allegations a person can face in the criminal courts. It can involve months, sometimes years, of investigation. It can bring police interviews, bail conditions, seized phones, frozen bank accounts, Crown Court proceedings, and, if convicted, the possibility of a lengthy prison sentence.
It is also an allegation that is often misunderstood.
Many people assume they can only be guilty if they personally carried out the offence. In a criminal conspiracy case, the prosecution may say that the offence lies in the agreement itself. In other words, a person can be charged because they are alleged to have agreed with others that a crime would be committed, even if the intended offence was not completed.
As criminal defence solicitors at JR Levins, we act in serious and complex cases across Liverpool, Merseyside, Manchester, Cheshire and the wider North West. Our work includes serious drugs cases, money laundering, murder, firearms allegations, fraud, county lines investigations and Crown Court proceedings.
If you are facing a conspiracy charge, or you are worried that you may be under investigation, the decisions made at the beginning of the case can matter enormously.
Experience in Very High Cost Cases (VHCCs)
JR Levins’ criminal defence team is accredited by the Legal Aid Agency to supervise and conduct Very High Cost Cases (VHCCs). These are some of the largest, longest-running and most complex criminal cases, and they often take the form of major conspiracy prosecutions involving multiple defendants and very substantial volumes of evidence.
That experience matters in conspiracy cases. Our team is accustomed to dealing with complex digital and financial evidence, large prosecution cases and lengthy Crown Court proceedings, including a multi-billion-pound international importation case said to be the UK’s longest criminal trial.
What is a conspiracy charge?
A conspiracy charge is based on an alleged agreement between two or more people to commit a criminal offence.
The prosecution does not always have to prove that the planned offence actually happened. In many cases, the central issue is whether there was an agreement, what the agreement was, and whether the defendant was knowingly part of it.
That means conspiracy cases often focus on evidence such as messages, phone contact, meetings, movements, money, vehicles, addresses and relationships between alleged co-defendants.
However, suspicion is not enough. Knowing someone involved in crime is not enough. Being present is not enough. The prosecution must prove the case against each defendant.
What must the prosecution prove?
In broad terms, the prosecution must prove that:
There was an agreement between two or more people.
The agreement involved a course of conduct that would amount to a criminal offence.
The defendant was knowingly part of that agreement.
The defendant intended that the plan would be carried out, or intended to play their part in it.
The detail matters. A person may be accused of being part of a conspiracy because of phone contact, friendship, family connection, use of a vehicle, presence at an address, or financial activity. Those facts may look suspicious when presented by the prosecution, but they may also have an innocent explanation.
A strong defence will examine whether the evidence really proves agreement, knowledge and intention.
Common conspiracy offences
Conspiracy can apply to many types of criminal allegation. Some of the most serious and common include:
Conspiracy to supply drugs
Conspiracy to supply or import controlled drugs
Conspiracy to commit fraud
Conspiracy to money launder
Conspiracy to murder
Conspiracy to supply firearms
Conspiracy to rob, burgle or steal
Conspiracy to cause serious violence
Each case is different. A conspiracy to supply Class A drugs will raise different issues from a conspiracy to commit fraud or a conspiracy to murder. But in every case, the question remains: can the prosecution prove the defendant was part of the alleged agreement?
Conspiracy to supply or import controlled drugs
Drug conspiracy cases are often large, complex and heavily reliant on phone evidence. They may involve allegations of county lines activity, wholesale supply, couriers, storage addresses, cash collection, encrypted communications or international importation.
Dave Woods and Liam Ferris have vast experience defending in drug cases, from county lines conspiracies to a multi-billion-pound international importation case said to be the UK’s longest criminal trial. David Woods and the wider JR Levins criminal defence team also regularly deal with serious Crown Court cases, including serious drugs allegations.
In these cases, the prosecution may rely on:
mobile phone downloads;
call data and cell site evidence;
encrypted messages;
ANPR and vehicle movements;
surveillance;
financial records;
drug valuations;
expert evidence about supply patterns.
A key issue is often role. Was the defendant really an organiser? Were they a courier, a user, a peripheral figure, a person under pressure, or not knowingly involved at all? The answer can make a major difference to both trial strategy and sentence.
Conspiracy to commit fraud or money laundering
Conspiracy to commit fraud and conspiracy to money launder cases often involve complex financial evidence.
The prosecution may allege that defendants agreed to obtain money or property dishonestly, or to move, conceal or transfer the proceeds of crime. These cases may involve companies, bank accounts, cryptoassets, invoices, false identities, online platforms, tax records or professional documents.
Important questions can include:
Did the defendant act dishonestly?
Did they know the money was criminal property?
Were they part of an agreement?
Did they simply follow instructions?
Has the prosecution overstated the loss, benefit or role?
Conspiracy to murder, supply firearms or commit serious violence
Allegations such as conspiracy to murder, conspiracy to supply firearms and conspiracy to cause serious violence are among the most serious cases in the criminal courts.
These cases may involve surveillance, weapons, alleged reconnaissance, phone evidence, covert recordings, encrypted messages or allegations of organised criminal activity.
The prosecution may argue that a person played a role in planning violence even if no attack ultimately took place. The defence must test the alleged plan, the reliability of the evidence, the meaning of communications, and whether the defendant truly intended the offence alleged.
Liam Ferris has represented defendants in high-profile murder cases and successfully defended one of two suspects charged with Cheshire’s first “no body” murder. David Woods is a Higher Court Advocate and has decades of experience in serious and complex criminal defence including homicide.
What evidence is used in conspiracy cases?
Conspiracy investigations are often built from many pieces of evidence rather than one single event. The prosecution may try to create a picture from:
phone downloads;
WhatsApp, Signal, Telegram or other messages;
encrypted communications;
cell site material;
ANPR evidence;
surveillance;
banking and cash evidence;
social media;
forensic evidence;
co-defendant evidence;
police intelligence;
expert reports.
This evidence can be powerful, but it can also be misunderstood. A phone may be attributed to the wrong person. A message may be taken out of context. A location record may show where a device was, not necessarily where a person was. A bank transfer may have a legitimate explanation.
In conspiracy cases, careful analysis of the evidence is essential.
What can happen if things go wrong?
The consequences of a conspiracy investigation can be severe, even before any trial.
A person may be arrested at home or work. Phones, computers, vehicles and business records may be seized. Bank accounts may be examined. Bail conditions may prevent contact with family members, friends or business associates. A person may be released under investigation for a long period while police continue to build the case.
If charged, the case may be sent to the Crown Court. In serious conspiracy cases, there may be multiple defendants, large volumes of evidence, lengthy hearings and significant delay before trial.
If convicted, the consequences can include:
a long prison sentence;
loss of employment or business;
damage to reputation;
restrictions on travel;
confiscation proceedings;
restraint or freezing orders;
financial penalties;
serious impact on family life;
future difficulties with professional regulation, immigration or security checks.
For some offences, the sentence for conspiracy can be as serious as the sentence for the completed offence. That is why early advice is so important. Mistakes made in interview, careless contact with co-defendants, deletion of messages, or attempts to explain matters without legal advice can make the position worse.
If you are under investigation, take advice before speaking to police, co-defendants, witnesses or anyone else connected to the case.
What sentence can a conspiracy charge carry?
The sentence depends on the offence that was allegedly planned.
A conspiracy to murder can carry life imprisonment. A conspiracy to supply Class A drugs can result in a lengthy custodial sentence. A conspiracy to supply firearms will be treated with particular seriousness. Fraud and money laundering conspiracies may lead not only to custody but also confiscation proceedings.
The judge will consider factors such as:
the offence alleged;
the scale and duration of the conspiracy;
the defendant’s role;
the level of planning;
the harm caused or intended;
the quantity of drugs, money or weapons involved;
previous convictions;
whether children or vulnerable people were exploited;
whether there was an early guilty plea;
personal mitigation.
Role is often critical. A leading organiser is likely to be treated differently from a person with limited involvement. The court must sentence the individual, not simply the conspiracy as a whole.
What should you do if you are under investigation?
If you have been arrested, invited to a voluntary police interview, contacted by police, or believe you may be under investigation for conspiracy, you should seek legal advice immediately.
Do not assume a voluntary interview is informal. It is an interview under caution. What you say may be used in evidence. Read: Do I really need a solicitor at a voluntary police interview?
A solicitor can advise on:
whether to answer questions;
whether to provide a prepared statement;
what disclosure has been provided;
whether further disclosure should be requested;
bail or release under investigation;
seized devices;
pre-charge engagement;
evidence gathering;
Crown Court preparation.
The right approach depends on the facts. There is no one-size-fits-all strategy.
