Being accused of conspiracy to murder is one of the most frightening and serious situations a person can face in the criminal justice system. Even hearing the words can cause overwhelming fear about the future, the possible penalties, and the impact on your loved ones. You may be unsure whether imprisonment is inevitable, whether there is any realistic chance of a suspended sentence, and what steps you can take to protect yourself. This article explains the offence of conspiracy to murder, the sentencing framework, how the courts approach these cases, and what you can do to achieve the best possible outcome.
Conspiracy to murder is an offence under the Criminal Law Act 1977. A person commits this offence if they agree with one or more others to unlawfully kill another person, intending that the killing will take place. The offence is complete as soon as the agreement is formed; the killing does not need to occur, and no steps need to be taken toward carrying it out.
This means that even discussions that go beyond casual fantasy and show a clear intention to commit murder can amount to conspiracy. The prosecution must prove an agreement and an intention that the victim’s death would be caused.
Conspiracy to murder can arise in many contexts. Some cases involve gang-related violence, revenge attacks, or disputes between individuals. Others may involve domestic or family breakdowns, planned retaliation, financial motives, or attempts to silence someone. It can also arise when a group agrees to commit a violent act that they know is likely to cause death, even if they did not identify a specific method.
Examples include agreeing to shoot, stab, or deliberately run down a person; arranging for someone else to carry out the killing; meeting to plan an attack; supplying weapons with the shared understanding that they will be used to kill; or coordinating roles such as lookout, driver, or attacker.
Unlike some lesser conspiracy offences, conspiracy to murder requires intent to kill, not merely intent to cause serious harm.
Conspiracy to murder is one of the most serious offences in English criminal law. It carries the same maximum sentence as murder itself: life imprisonment. Sentencing depends on the seriousness of the planned killing, the role of the defendant, the degree of planning, and any aggravating or mitigating factors.
Although sentences vary, the following general ranges apply:
Even conspiracies that never progressed beyond early planning stages usually attract substantial custodial sentences because the intention to kill is considered extremely harmful in itself.
There is no sentencing scenario in which conspiracy to murder attracts a short custodial term. The seriousness is built into the offence: the intention to take a life places the offence at the top end of the criminal scale.
A suspended sentence is a custodial sentence that the court imposes but suspends for a fixed period of time. A suspended sentence is only available when the custodial term is two years or less. During the suspension period, the defendant must comply with strict conditions such as unpaid work, rehabilitation activity requirements, curfews, exclusion zones, treatment requirements, or supervision by probation.
If the defendant complies with the conditions and commits no further offences during the suspension period, the sentence will not be activated. If they breach the terms or commit another offence, the court is likely to activate the custodial term.
The purpose of a suspended sentence is to allow the court to impose a punishment that reflects the seriousness of the conduct while still enabling the defendant to remain in the community.
That said, for an offence to be eligible for a suspended sentence, the custodial term must fall within the two-year threshold.
In practical terms, no. A suspended sentence for conspiracy to murder is considered virtually impossible in the criminal courts of England and Wales. This is because:
Even in the rarest and most unusual circumstances – such as extreme personal mitigation, coercion, or abandonment of the plan at an early stage – the sentencing range still falls far beyond the point where suspension is legally permitted.
As such, as a matter of both law and reality, a suspended sentence for conspiracy to murder is not an available outcome.
Although a suspended sentence is not possible, understanding the factors courts consider can help determine the appropriate length of sentence.
Conspiracy to murder always results in a prison sentence. There is no realistic scenario in which the offence does not cross the custody threshold. A prison sentence is inevitable because:
The question is not whether custody will be imposed, but rather how long the custodial sentence will be. Even in the least serious cases – where the plan was abandoned early, where the defendant was under pressure, or where no steps were taken to carry out the plan – sentences still typically begin from around seven to eight years for adults.
Although a suspended sentence is not possible, there are several things you can do to reduce your overall sentence and improve your position.
