Gateway requirements can be found in the CORENET X Code of Practice, which can be found here. Each Gateway is only considered cleared when all relevant requirements from the agencies involved in the Gateway are met. Technical departments of each agency are involved if their requirements need to be cleared at the respective gateways. Even if only one agency's clearance is required, submissions are still made through CORENET X, with the Qualified Person (QP) indicating which agency’s approvals are not applicable. The application will then be directed to the agency whose approval is required. More information on the new regulatory approval process can be found here.
