Firearms offences: certificates, prohibited weapons and minimum sentences

Updated 2026-11-05 · Checked against sources 2026-11-05 · England & Wales

Possessing a firearm or ammunition without a certificate (Firearms Act 1968 s.1) carries up to 5 years, or 7 years for a shortened shotgun or converted imitation. Possessing a prohibited weapon such as a handgun or automatic weapon (s.5) carries up to 10 years and, for most such weapons, a minimum of 5 years if the offender was 18 or over when the offence was committed (3 years if 16 or 17), unless there are exceptional circumstances.

The offences

Air weapons and imitations

Air weapons need no certificate unless over 6 ft lb for a pistol or 12 ft lb otherwise (Firearms (Dangerous Air Weapons) Rules 1969); those using a self-contained gas cartridge are prohibited (s.5(1)(af)). Making, modifying, selling or importing a realistic imitation firearm is a summary offence (Violent Crime Reduction Act 2006 s.36).

Strict liability

Possession under ss.1 and 5 is strict liability. It is no defence that the person did not know the item was a firearm, did not know what was in a bag or box, or thought it was something innocent (R v Zahid [2010] EWCA Crim 2158). The issues are usually classification and possession.

Minimum sentence

For the main s.5 weapons (not s.5(1)(b) sprays and stun guns), and intent, public place and trespass offences involving them, the court must impose at least 5 years if the offender was 18 or over when the offence was committed, or 3 years if 16 or 17 then, unless exceptional circumstances relating to the offence or offender justify less (Sentencing Act 2020 s.311 and Sch.20). It does not apply to under-16s. A guilty plea cannot reduce the sentence below it.

In practice

Forensic classification of the weapon often decides whether the minimum applies. Early advice matters.
