The EU legislation introduces two tiers of regulation for ANSPs:

• the certificate, or entry ticket, which confirms the provider's implementation of safety, financial, security and quality management measures; and
• designation, which formally nominates an ANSP to provide services at a specified location.

Further information regarding Certification and Designation can be found on the CAA’s Single European Sky web pages.

Certification and Designation Requirements can be found in CAP 670 ATS Safety Requirements, Part B, Section 1, APP 03.
