Offensive Weapons Act

The Offensive Weapons Act May 2019 brought in tough new measures that strengthen law enforcement’s response to violent crime. The Act also addresses the issue of “acid attacks” using corrosive substances (some of which are used in the pool and spa industry). This information aims to outline what is in the Act and how our industry can prepare for the changes that are now in place. The measures within the Offensive Weapons Act are designed to provide greater protection for the public and communities and deliver on the government’s commitment to tackle serious violence and provide law enforcement with the powers they need to keep the public safe. The relevant parts of the Act in relation to the pool and spa industry have created:

  • A criminal offence of selling (remotely, online and over the counter) a corrosive product to a person under the age of 18 – the substances and concentration levels of what constitutes a corrosive product are set out in the Act.
  • A criminal offence of possessing a corrosive substance in a public place – there is a defence of possessing the corrosive substance for good reason.
  • Criminal offences prohibiting the delivery of corrosive products to a residential address or “locker” for collection.
  • Criminal offences on delivery companies of delivering a corrosive product on behalf of a seller based outside the United Kingdom to a person under 18.
  • Delivered goods must be marked accordingly and only delivered “into the hands” of a person aged 18 or over. The relevant substances (and concentrations) are included in the table opposite:

Any suspicious transactions (B2C and B2B) of “Regulated” substances and/or “Reportable” substances must be reported as a legal requirement. It is also a legal requirement to report any significant loss or theft of reportable and regulated chemicals, making it clear that it is a Reportable/Regulated substance under the EPP Act.
