Britain's gun laws read as close to prohibition as any democracy gets. Handguns were banned outright after the Dunblane shooting, through the Firearms (Amendment) Acts of 1997, and most semi-automatic rifles went after Hungerford in 1988. What remains legal — shotguns, bolt-action rifles, some .22 rimfire semi-automatics — sits behind a licensing regime that on paper vets every owner before a single cartridge changes hands. In practice that regime is an administrative machine run separately by 43 territorial police forces in England and Wales, plus Police Scotland, and how well it works depends on staffing, judgement calls and paperwork moving on time.

The architecture dates from the Firearms Act 1968 and splits civilian ownership into two tracks. A firearm certificate, under Section 1, covers rifles and higher-powered guns; the applicant must demonstrate a good reason for each individual weapon — deer stalking on named land, membership of a Home Office approved target club, professional pest control — and the certificate specifies the exact guns and the ammunition quantities the holder may possess. A shotgun certificate, under Section 2, works the other way round: the chief officer must grant it unless satisfied the applicant has no legitimate purpose or would present a danger to public safety or the peace. That reversed burden, a legacy of shotguns' place in rural life, means refusing a shotgun certificate is legally harder than refusing a rifle.

Both certificates run for five years. Applications need referees, a home visit from a firearms enquiry officer to inspect the locked cabinet that secure-storage rules require, and checks against the Police National Computer and local intelligence. Around half a million shotgun certificates and roughly 150,000 firearm certificates are on issue at any time, covering well over a million legally held guns. Fees, frozen for years at £79.50 for a shotgun grant, cover only a fraction of what forces spend processing each file, which is one reason licensing units are chronically under-resourced.

Since 2021, statutory guidance issued under the Policing and Crime Act 2017 has required forces to obtain information from an applicant's GP before granting or renewing a certificate, and a firearms marker is placed on the patient record so the surgery can alert police if relevant concerns arise during the certificate's life. The guidance followed the Plymouth shootings of August 2021, in which Jake Davison killed five people with a shotgun that Devon and Cornwall Police had confiscated after an assault and then handed back. The 2023 inquest found the force's licensing decisions catastrophically wrong at several stages — and it was not the first such verdict. Her Majesty's Inspectorate of Constabulary had said much the same in general terms in its 2015 report Targeting the Risk, which found forces routinely departing from Home Office guidance and sitting on expired certificates.

Where discretion does the work

The statute sets the frame, but almost every consequential decision is discretionary. "Danger to public safety", "good reason" and "suitability" are judgements made by licensing staff and signed off in the chief officer's name, with an appeal route to the Crown Court for refused applicants. That produces variation: one force may treat a decades-old conviction or a domestic-abuse callout as disqualifying, another may weigh it differently. The National Police Chiefs' Council has pushed standardisation through its firearms licensing portfolio, and the College of Policing publishes authorised professional practice, but neither binds a chief constable's individual determination. Scotland, which additionally licenses air weapons under its own 2015 Act, runs the same discretionary model through a single national force.

The renewal backlog

The system's most persistent weak joint is timing. When a five-year certificate lapses before the force has processed the renewal, the gun does not vanish; forces issue temporary permits under Section 7 of the 1968 Act, which extend possession without any of the fresh checks a renewal is supposed to trigger. During pandemic-era backlogs some forces had thousands of holders on Section 7 permits for months, and shooting organisations and police inspectorates, for once aligned, both called the practice a hole in the vetting cycle. Every review since 2015 has landed on the same trio of recommendations: fees that fund the checks properly, consistent national decision standards, and renewal processing that starts early enough to finish on time. The law is strict. The question each report keeps asking is whether the administration behind it is.
