Selling Knives to Minors: Offence and Sentencing in England and Wales 

What Law Prohibits Selling Knives to Minors?

The offence of selling a knife to a person under 18 is primarily governed by the Criminal Justice Act 1988 and subsequent legislation relating to offensive weapons. 

Under the law, it is unlawful to sell: 

• a knife 
• a knife blade 
• any sharply pointed or bladed article 

To someone under the age of 18, The offence applies whether the sale occurs: 

• in a shop 
• online 
• through mail order 
• via a third-party retailer 

The legislation is intended to limit the availability of knives to young people and to support broader efforts to reduce knife crime.  

Retailers must therefore ensure that they operate robust systems to prevent underage sales. 

What Counts as a Knife Under UK Law?

The legislation applies to most bladed or sharply pointed items. This includes many products commonly sold in shops or online. 

Examples include: 

• Kitchen knives 
• Craft knives 
• Hunting or outdoor knives 
• Utility blades 
• Certain tools containing blades 

The offence focuses on whether the item contains a blade or sharply pointed edge capable of causing injury. 

Retailers must therefore treat many bladed products as age-restricted items and ensure proper age verification procedures are in place. 

Sentencing for Selling Knives to Minors

Courts in England and Wales follow guidance issued by the Sentencing Council when dealing with offences involving the sale of knives to children. 

These guidelines aim to ensure that similar cases are treated consistently and that penalties reflect the seriousness of the offence. 

Factors considered by the court may include: 

• The level of negligence involved 
• Whether proper age checks were carried out 
• The number of knives sold 
• Whether the sale was part of a wider pattern of misconduct 
• The financial size of the business 

Sentencing for Organisations

Companies and businesses cannot receive custodial sentences. Instead, penalties usually involve financial sanctions. 

Fines can vary significantly and may depend on the organisation’s turnover. In serious cases involving larger businesses, fines may reach substantial amounts. 

Courts will assess: 

• The company’s size 
• Its compliance procedures 
• Whether previous offences have occurred 
• Whether the company cooperated with investigators 

The objective is to impose a penalty that is proportionate and acts as a deterrent.

Sentencing for Individuals

Individuals responsible for selling a knife to a minor may face a range of penalties. 

Possible outcomes include: 

• Fines 
• Conditional or absolute discharges 
• Community orders 
• In rare cases, custodial sentences 

The sentence will depend on the circumstances of the offence and the defendant’s level of responsibility. 

For example, the court may consider whether: 

• The individual deliberately ignored age restrictions 
• The sale occurred due to poor training or oversight 
• The defendant has previous convictions 

Courts aim to ensure that sentences reflect both the seriousness of the offence and the need to deter similar conduct. 

Defences to the Offence

In some cases, a person accused of selling knives to minors may have a legal defence. 

One key defence involves demonstrating that the defendant took all reasonable precautions and exercised due diligence to avoid committing the offence. 

This may involve showing that the business had: 

• a robust age-verification policy 
• Staff training procedures 
• Clear internal compliance systems 
• Warning signage regarding age restrictions 

If the court is satisfied that reasonable precautions were in place, this may affect the outcome of the case.
