UK Civil Aviation Regulations

These are published by the CAA on our UK Regulations pages. EU Regulations and EASA Access Guides published by EASA no longer apply in the UK. Our website and publications are being reviewed to update all references. Any references to EU law and EASA Access guides should be disregarded and where applicable the equivalent UK versions referred to instead.


At 23:00 on 31 December 2020 the UK left the European Union aviation system, and as such is no longer part of European Union aviation institutions, including the European Union Aviation Safety Agency (EASA). At the end of the UK/EU Agreement transitional period, the Withdrawal Acts brought all EU law that was in force and applicable at that point under UK jurisdiction; view the SERA Standardised European Rules of the Air for further information.

Regarding the Standardised European Rules of the Air (SERA) Regulation, this is now the law as retained (and amended in UK domestic law) under the European Union (Withdrawal) Act 2018. The supporting Acceptable Means of Compliance and Guidance Material that were published by EASA and in force on 31 Dec 2021 have been adopted by the CAA. View the UK SERA Regulation and the AMC and GM for more information.

The UK’s Air Navigation Order and Rules of the Air Regulations are replicated within CAP393.

Permissions, authorisations and exemptions relating to both SERA and the UK Rules of the Air are found in the List of Official Record Series Publications series under ORS4.

Future development

The CAA is establishing a rulemaking and policy development process to address any changes to legislation, Acceptable Means of Compliance or Guidance material caused by changes to the 'parent' ICAO material, or any other requirement to amend the content of SERA content.
