ANSP Requirements

All organisations intending to provide an air navigational service must be in possession of a certificate issued by the CAA in accordance with UK Regulation (EU) 550/2004, (the service provision regulation), article 7.

ATS providers will also be required to be ‘designated’ to provide their services on an exclusive basis within a specific airspace block, at a specific location, in accordance with UK Regulation (EU) 550/2004, article 8.

Where the ATS provider provides an Air Traffic Control Service they must also be certified as a Training Organisation in accordance with the requirements of UK Regulation (EU) 2015/340.

See our guidance on ATCO training organisation certification.

To achieve certification as an ATS provider an organisation must demonstrate compliance with Annex III and Annex IV of UK Regulation (EU) No. 2017/373, (the common requirements for the provision of air traffic management/air navigation services).

To achieve certification as a CNS provider an organisation must demonstrate compliance with Annex III and Annex VIII of UK Regulation (EU) No. 2017/373.

To achieve certification as a MET provider an organisation must demonstrate compliance with Annex III and Annex V of UK Regulation (EU) No. 2017/373.

Noncomplex organisations may apply for ‘Limitation’ from some of the financial and business requirements of UK Regulation (EU) No. 2017/373. Further information on limited certificates will be provided on application.

Application for Designation (ATS providers only)

When an organisation applying for initial ANSP certification and designation to provide an ATS has successfully demonstrated sufficient compliance with the applicable legislation, the CAA will issue an ANSP certificate and a 'letter of designation', relevant to the location where the services are to be provided.

Where an ANSP, already holding a certificate, intends to provide an ATS at an additional location the ANSP must make application to the CAA for designation, at that location, on CAA on form SRG 1428 with appropriate payment. Please refer to CAA Scheme of Charges.

The certified ANSP must resubmit their compliance matrices which must now demonstrate how compliance with the relevant legislation is achieved at all locations where it is intended to provide a service.
