Quick Answer
Police will expect ammunition covered by your firearm certificate to be secured against unauthorised access. Separate locked storage is Home Office best practice, rather than a universal rule that it must be in a different cabinet. Your arrangements should suit your home, household and the quantities held, and you must remain within your certificate's ammunition limits. Ordinary shotgun cartridges have different legal requirements, but responsible storage still matters.
Distinguish ammunition types first
In Great Britain, the standard firearm certificate security condition requires relevant firearms and ammunition to be stored securely to prevent access by unauthorised people, subject to the condition's exceptions for use, transport and related circumstances. Read your own certificate carefully and follow any additional conditions.
Ordinary shotgun cartridges do not generally have the same statutory secure-storage requirement as ammunition held on a firearm certificate. That does not make leaving them accessible sensible. Locking cartridges away is sensible for both safety and security.
Northern Ireland has a different firearms licensing framework. If you are licensed there, check your conditions and PSNI guidance rather than assuming Great Britain arrangements apply.
What does the official guidance say?
The Home Office Firearms Security Handbook, paragraphs 2.46-2.47, says section 1 ammunition must be secure and recommends its own individual secure storage as best practice. Paragraph 1.4 explains that the handbook is guidance, not a statement of law. Your certificate conditions remain binding; GOV.UK confirms you must follow the conditions attached to your certificate.
What secure ammunition storage looks like
For ammunition held on a firearm certificate, a separately locked ammunition compartment within a suitable gun cabinet is a common arrangement. A separate, securely installed ammunition safe can also be appropriate. Separation does not necessarily mean another room or a completely separate cabinet.
Police will normally consider:
- Whether the container resists unauthorised access and is secured appropriately.
- Whether ammunition has its own locked storage, in line with Home Office best practice and any applicable certificate conditions.
- Who can access keys, combinations or spare keys.
- Whether children, visitors or other household members could gain access.
- Whether the storage has sufficient capacity for the quantities you may lawfully hold.
- Whether the location creates avoidable security or safety risks.
A cabinet standard alone does not make the whole arrangement satisfactory. Installation, location and everyday access control also matter. See our guide to gun cabinet requirements and police expectations.
Keep control of keys and codes
Do not leave ammunition keys on an obvious hook, in an unlocked drawer or alongside the cabinet. Keep combinations confidential and do not assume that a partner or another certificate holder is automatically authorised to access your ammunition.
If another person needs access, establish that their authority covers the ammunition concerned and agree suitable arrangements with your firearms licensing department. Shared storage needs particular care because access permissions may differ between users.
Be ready to explain your arrangements
During a home visit, an enquiry officer may ask you to show the ammunition storage, explain access control and discuss the quantities held. Keep ammunition organised so that you can identify what you possess and check it against your certificate.
A shooting log or stock record can help demonstrate control, but it does not replace your certificate, required transaction entries or physical security. Check possession limits before acquiring ammunition, including ammunition you make yourself.

Store cartridges responsibly and plan for changes
Keep ordinary shotgun cartridges in a dry, suitable location, protected from heat, ignition sources and unauthorised access. A locked cupboard or appropriate secure container is a sensible precaution, particularly where children or visitors are present. Avoid obstructing escape routes or creating unnecessary fire risks.
If you increase ammunition quantities, move house or change your household arrangements, review whether your existing storage remains suitable. Loose powder and primers can involve additional rules, so do not assume ordinary loaded-ammunition arrangements cover every reloading component.
Security also matters between home and the shooting ground. Our guide to storing and transporting ammunition covers practical precautions. If ammunition goes missing or you suspect theft, contact police promptly and follow their instructions. See what to do after a firearm or ammunition loss or theft.
Practical Bottom Line
Keep firearm certificate ammunition secure; use separately locked storage as best practice, control access carefully and stay within your authorised limits. Store shotgun cartridges responsibly even where the same statutory security condition does not apply. If your circumstances are unusual, confirm suitable arrangements with your firearms licensing department before relying on them.
