Explosives licensing

All explosives certificates are issued in accordance with the Explosives Regulations (ER) 2014.  Please allow 12 weeks for your application to be processed.

All explosives certificates are issued in accordance with the Explosives Regulations 2014 which states all regulations that must be followed when manufacturing, handling or storing explosive materials. A  free explosives guidance booklet is available to download from the Health and Safety Executive website.

The two main types of explosive certificate are:

  • Acquire Only (EXA) - this allows you to acquire a defined amount of explosives (e.g. one kilogram) from an approved supplier and use it on that day. Any unused explosive must either be returned to the supplier or destroyed in an approved manner.
  • Acquire and Keep (EXK) - this allows you to stores explosives at a location for the duration of the certificate. The maximum amount of explosives that may be stored will depend on the nature of the explosives and the construction of the store. A Registered Competent Authority document (RCA) allowing you to transport the explosives is issued as part of the explosive certificate.

Fees

For the majority of explosives certificates there is no fee for either an EXK or an EXA. However, if explosives are to be stored above a certain quantity or for a certain amount of time then a fee is sometimes chargeable. The fee due can vary considerably being dependant on hazard type, the length of storage and the amount stored (normally above 15kg).

Please contact the unit if you believe you may have to pay a fee.

Please be aware that any fee paid under the explosives regulations is paid in advance for the work done by the unit and is not normally refundable even if a certificate is refused.

Forms
