From 1 June 2012 explosives certificates issued under the Control of Explosives Regulations 1991 (COER) will also fulfil the function of the RCA document.

From 1st June 2012 the RCA approval document will be incorporated into newly issued COER explosive certificates. This removes the need to also apply to HSE for a separate approval to transfer explosives within Great Britain.

Applications for the new combined COER explosive certificate/RCA are via your local Police Explosives Liaison Officer.
