UK Knife Crime Sentencing Explained

Being caught carrying a knife in public can result in a criminal prosecution and, in some circumstances, a prison sentence. However, carrying a knife does not automatically mean that you will be sent to prison.

The sentence for a knife crime offence depends on the circumstances of the case, including the type of weapon, where it was found, whether it was used or threatened to be used, previous convictions and any mitigating factors.

If you or your child have been arrested or charged with a knife crime offence, getting specialist criminal defence advice as early as possible can be important. At Stryders, our experienced criminal defence solicitors can provide expert representation from the outset, helping to protect your rights and work towards the best possible outcome.

Is It Illegal to Carry a Knife in Public?

Generally, it is an offence to have an article with a blade or point in a public place without a good reason or lawful authority. A public place can include roads, shops, public transport, parks and other places where members of the public have access.

There are exceptions. For example, a person may have a lawful reason for carrying a knife for work purposes. However, carrying a knife for self-defence or protection is not generally considered a lawful reason.

The law can also apply to knives and offensive weapons carried on education premises, with specific offences covering possession in schools and other educational settings.

Can You Go to Prison for Carrying a Knife?

Yes. An adult convicted of possessing a bladed article or offensive weapon in a public place can receive a custodial sentence.

The maximum sentence for the relevant possession offences is currently four years’ custody. The Sentencing Council guideline gives an offence range from a fine up to two years and six months’ custody, although the maximum available sentence is four years.

This does not mean that every person convicted of carrying a knife will receive a prison sentence. The court must consider the individual circumstances of the offence and the offender when deciding the appropriate sentence.

What Factors Affect Knife Crime Sentencing?

The Sentencing Council guideline requires the court to consider the seriousness of the offence, including culpability and harm.

Factors that can affect the seriousness of a knife possession offence include:

  • The type of knife or weapon involved
  • Whether the weapon was particularly dangerous
  • Where the offence took place
  • Whether anyone was caused serious alarm or distress
  • Whether the offence took place at a school or another location where vulnerable people were present
  • Whether there was a risk of serious disorder
  • The offender’s previous convictions
  • Whether there was significant planning or preparation
  • Whether the offender acted as part of a group

The court will also consider mitigating circumstances. These can include good character, little or no planning and cooperation with the police.

Is There a Minimum Prison Sentence for Carrying a Knife?

There can be. For adults, where a person aged 18 or over is convicted of a second or further relevant knife or offensive weapon offence, a statutory minimum sentence of six months’ imprisonment can apply.

There is an exception where the court considers that there are exceptional circumstances relating to the offence or offender that justify not imposing the minimum sentence.

This means previous convictions can be particularly important in knife crime cases.

The law is different for children and young people, who are sentenced under specific youth justice provisions.

What if the Knife Was Not Used?

A person does not have to use a knife for a criminal offence to have been committed.

Possessing a bladed article in a public place can itself be an offence if there is no good reason or lawful authority for having it.

However, the fact that a knife was not used or produced may still be relevant when the court considers the seriousness of the offence and the appropriate sentence.

This is one reason why the circumstances surrounding the possession can be important when defending a knife crime allegation.

What if I Was Carrying a Knife for Protection?

Carrying a knife because you believe you need it for protection does not generally provide a lawful excuse for possessing it in public.

A person may feel that carrying a knife makes them safer, particularly if they are concerned about becoming a victim of crime. However, that does not generally make possession lawful.

If you have been stopped, searched or arrested because of a knife, it is important to explain the circumstances to a solicitor rather than assume that your reason for carrying it will automatically amount to a defence.

What Happens if You Are Charged With Possession of a Knife?

The circumstances of the case will determine what happens next.

Depending on the allegation and the evidence, a case may be dealt with in the Magistrates’ Court or proceed to the Crown Court. The prosecution will need to prove the offence, while the defence may need to consider issues such as whether the item was a bladed article, where it was found and whether there was a lawful reason for possession.

The evidence surrounding the discovery of the knife can also be important. This may include police statements, body-worn video, CCTV, witness evidence and what was said during the investigation.

Getting legal advice at an early stage can help ensure that the circumstances of the allegation are properly examined.
