What is the sentence for attempted murder in the UK?

Attempted murder is one of the most serious criminal offences in the UK, carrying severe penalties that reflect the gravity of the crime. 

If you’re seeking to understand the legal process this guide explains what attempted murder means, the sentences courts can impose, and the factors that influence sentencing decisions. 

Understanding attempted murder

Attempted murder occurs when someone takes a direct step towards killing another person with the intention of causing their death, but the victim survives. It’s a specific intent crime, meaning the prosecution must prove beyond reasonable doubt that the defendant intended to kill, not merely to cause serious harm.

Attempted murder vs other violent offences

Murder involves the unlawful killing of another person with the intention to kill or cause grievous bodily harm (GBH). With attempted murder, death doesn’t occur, but the intent to kill must be proven.

Manslaughter involves unlawful killing without the intent to kill or cause GBH, often where there’s loss of control or diminished responsibility. Other serious offences, like wounding with intent (Section 18 GBH), require only the intent to cause serious harm, not to kill.

The two elements of attempted murder

The legal test for attempted murder has two essential elements.

The mens rea (mental element) requires proof that the defendant specifically intended to kill the victim – recklessness or intent to cause serious injury isn’t sufficient.

The actus reus (physical element) requires proof that the defendant took more than merely preparatory steps towards committing the murder. This means they must have moved from planning into action, though they don’t need to have completed every step necessary to cause death.

Maximum and typical sentences for attempted murder 

The maximum criminal sentence for attempted murder in England and Wales is life imprisonment. This reflects the seriousness with which the law treats this offence. An attempt to take someone’s life is treated almost as gravely as murder itself, even though the victim survived.

Minimum terms for life sentences

When a court imposes a life sentence for attempted murder, it will also set a minimum term (sometimes called a ‘tariff’). This is the minimum period the offender must serve in prison before they can be considered for release by the Parole Board.

The minimum term reflects the seriousness of the specific offence, taking into account both aggravating and mitigating factors. Even after the minimum term expires, release isn’t automatic: the offender must satisfy the Parole Board that they no longer pose a risk to the public.

Average sentence lengths for attempted murder

In practice, sentence lengths for attempted murder vary considerably depending on the circumstances.

The most serious cases involving significant premeditation, use of weapons, or particularly vulnerable victims can result in minimum terms of 20 or more years. Less serious cases, perhaps involving less premeditation or stronger mitigating factors, might result in determinate sentences (fixed-term sentences) rather than life imprisonment, though these are still substantial, typically ranging from 10 to 20 years. Cases falling in the middle ground often receive life sentences with minimum terms of 10 to 20 years. 

Factors influencing attempted murder sentencing

When sentencing for attempted murder, judges must follow sentencing guidelines whilst considering all the circumstances of the individual case. The resulting sentence can vary significantly based on aggravating and mitigating factors.

Aggravating factors for attempted murder

Aggravating factors increase the seriousness of the offence and typically result in longer sentences.

These include: 

• Significant premeditation and planning, which demonstrates the attack wasn’t impulsive but carefully thought out
• The use of weapons, particularly firearms or knives
• Deliberately targeting vulnerable victims, such as children, elderly people, or those with disabilities
• Previous convictions, especially for violent offences
• Committing the offence in front of children or in the victim’s home
• If the attempt involves torture, sadistic conduct, or was carried out for financial gain.

Mitigating factors for attempted murder

Mitigating factors can reduce the sentences by showing there are reasons to be more lenient. 

Examples include:

• Mental health conditions or learning disabilities that affected the defendant’s actions (though not amounting to a complete defence)
• Demonstrating genuine remorse through early admissions, cooperation with police, or attempts to help the victim
• Lack of previous convictions, particularly for violence, suggesting the offence may be out of character
• If the defendant acted under significant provocation (though not enough to amount to a defence of loss of control)
• Youth, immaturity, or personal circumstances (such as being a sole carer).

How judges balance these factors

Judges must carefully weigh the aggravating and mitigating factors against each other. 

A case with strong aggravating features might result in a very long minimum term, even if some mitigation exists. On the other hand, significant mitigation in a case with fewer aggravating features will  result in a more lenient sentence. 

The process is detailed and nuanced, reflecting the complexity of human behaviour and circumstances.

Special considerations for attempted murder sentencing

Certain circumstances require special consideration when criminal courts determine appropriate sentences for attempted murder

Juvenile offenders

The framework for attempted murder sentencing operates differently for juvenile offenders (those under 18 at the time of the offence). 

Young offenders are sentenced under different principles that prioritise rehabilitation alongside punishment. While juveniles can receive life sentences for attempted murder, these are imposed only in the most serious cases. Courts must consider the welfare of the child as a primary consideration and assess their maturity and understanding.

Minimum terms for juveniles are typically significantly shorter than for adults, reflecting their age and capacity for change. Young offenders are detained in specialised youth facilities rather than adult prisons, at least initially.

High-profile or unusual cases

Sentencing trends in high-profile attempted murder cases sometimes attract public attention and debate. Cases involving celebrity victims, gang violence, or terrorist-related attempts often received extensive media coverage. While these cases follow the same legal principles, they may involve particularly serious aggravating factors that result in lengthy sentences. 

It’s important to understand that the sentence reflects the specific facts of each case rather than who the victim is. The law treats all victims equally, though the particular circumstances of how and why the attempt occurred will naturally vary.

Judges may be required to explain their sentencing decisions publicly, setting out which factors they’ve considered and how they’ve reached the final sentence. This transparency ensures accountability and helps the public understand that attempted murder sentences aren’t arbitrary, but are carefully reasoned decisions based on established principles. 

Public perception vs reality 

Media coverage of attempted murder cases can sometimes create misunderstandings about sentence outcomes. 

High-profile cases might generate headlines suggesting that sentences are either too harsh or too lenient, often without providing the full context of the circumstances involved. The public may question why one attempted murder results in a life sentence with a 25-year minimum term, whilst another results in a 12-year determinate sentence, assuming inconsistency in the system.

The reality is that attempted murder cases vary enormously in their facts. A meticulously planned attack with a deadly weapon on a vulnerable victim will receive a far more severe sentence than an impulsive act by someone with mental health issues who immediately showed remorse and called for help. These aren’t inconsistencies – they’re the justice system working as intended, tailoring sentences to reflect the specific circumstance and culpability in each case. 

It’s also worth noting that when the media reports someone has been sentenced to “18 years” for attempted murder, this may refer to a determinate sentence, where the offender will typically serve half in custody and the remainder on licence in the community. For life sentences, the minimum term report is the earliest point at which parole can be considered, not a guaranteed release date – many offenders serve considerably longer.

Understanding these realities helps provide perspective on how attempted murder sentencing actually operates: balancing punishment, deterrence, public protection, and the specific circumstances of each case in accordance with law and consistent principles.

Summary

Attempted murder is treated with utmost seriousness by UK courts, reflecting society’s view that deliberately trying to take another person’s life is one of the gravest crimes. With a maximum sentence of life imprisonment and typical sentences involving many years in custody, the consequences are severe and life-changing. 

However, sentencing isn’t a one-size-fits-all: judges carefully consider the specific circumstances of each case, weighing aggravating factors against mitigating ones to reach a fair and proportionate sentence.
