If you manufacture or store explosives you need either to register or apply for a licence, depending on the quantities of explosives involved.
Registration is a simplified process which applies where smaller quantities of explosives are to be stored. Registration allows up to 250kg (depending on the hazard type) of explosives to be stored. This weight is the net weight of the explosive contained in the article (NEQ), not the gross weight of the article itself.
For quantities in excess of this, more hazardous explosive types and for all manufacturing processes, it is necessary to obtain a licence. Powys County Council issues licences for storage but licences for manufacture must be obtained from the Health & Safety Executive. Some materials, for example, blasting explosive or black powder, require an explosives certificate and this can be obtained from Dyfed Powys Police.
If you store less than 5kg of explosives that don't require an explosives certificate or less than 15kg of small arms ammunition, then you don't need to be registered or licensed. Certain exemptions apply to the short term storage of fireworks; please contact Trading Standards for more information.
If you wish to store between 5kg and 250kg (NEQ) you require an explosive registration certificate.
If you wish to keep between 250kg and 2,000kg (NEQ) you require an explosive storage licence. If you wish to store over 2000kg you will need to contact the Health & Safety Executive. Explosives stored at quarries and similar premises are controlled by the Police.
Registrations and licences are valid for up to 5 years; a fee is payable dependent upon the amount of explosives stored. Different fees apply for renewals and variations or transfers.
You will also need to apply for a separate (additional) fireworks licence if you intend to supply or expose for supply fireworks other than during the following periods:
A fireworks licence is valid for one year.
