Background

The Civil Aviation Authority (CAA) is the UK's independent aviation regulator, established by the Civil Aviation Act 1972. Its REMIT covers certifying aircraft and airlines for airworthiness and air operator licensing, managing airspace classification and drone integration, overseeing airport economic regulation, enforcing passenger consumer-protection rules, and investigating aviation safety incidents alongside the Air Accidents Investigation Branch. It regulates thousands of licensed aerodromes and UK-registered aircraft and licenses several hundred air operators.

As the UK's designated national supervisory authority following Brexit, the CAA took on functions previously handled jointly with the European Union Aviation Safety Agency, including issuing its own UK-specific aircraft type certificates. Its REMIT expanded further with the Space Industry Act 2018, which gave it licensing responsibility for orbital and sub-orbital spaceflight launched from UK territory, extending the CAA's certification role beyond conventional aviation into commercial spaceflight.

The post-Brexit pattern of building domestic equivalents to EASA frameworks in aviation is now extending to emerging sectors, positioning the CAA as a gatekeeper for both aircraft and spacecraft operating in or through UK-managed airspace.

Common Questions
What does the Civil Aviation Authority regulate in the UK?
The CAA regulates aviation safety, airspace, UK-licensed aerodromes, air operators, passenger consumer rights, and commercial spaceflight licensing. Post-Brexit it also issues UK-specific aircraft type certificates that were previously handled jointly with EASA.Source: GOV.UK
Why was the CAA involved in the UK space-pharma regulatory pathway?
The CAA's Space Industry Act 2018 licensing powers cover any spacecraft launching from or transiting UK-managed airspace. A pharmaceutical payload mission needs CAA launch and re-entry approval as well as MHRA product authorisation, so the CAA was a necessary co-signatory on the March 2026 joint pathway.Source: GOV.UK
Is the CAA the same as EASA after Brexit?
No. The CAA is the UK's independent national aviation regulator; EASA is the European Union agency. Following Brexit, the CAA took on functions previously shared with EASA, including issuing UK-specific aircraft type certificates. The two bodies cooperate on mutual recognition but are legally separate.Source: GOV.UK
