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.



It should be noted that only Theoretical Knowledge Examinations completed with a Competent Authority, which is a Member State of the European Union Aviation Safety Agency (EASA), that were completed by 31 December 2020, will be accepted by the Civil Aviation Authority (CAA). This is in accordance with the European Withdrawal Act 2018 as amended.

The validity period of such Theoretical Knowledge Examinations is in accordance with FCL.025(c)(1), of UK Regulation (EU) No 1178/2011, from the date of the final examination is:

  • For the issue of a light aircraft pilot licence or a private pilot licence, for a period of 24 months.
  • For the issue of a commercial pilot licence, instrument rating (IR) or En-Route instrument rating (EIR), for a period of 36 months.

Should an individual have part completed some Theoretical Knowledge Examinations with an EASA Member State by 31 December 2020 and completed the remainder after that date with the CAA, the validity period of such Theoretical Knowledge Examinations is in accordance with FCL.025(c)(1), of UK Regulation (EU) No 1178/2011, from the date of the final examination is:

  • For the issue of a light aircraft pilot licence or a private pilot licence, for a period of 24 months.
  • For the issue of a commercial pilot licence, instrument rating (IR) or En-Route instrument rating (EIR), for a period of 36 months.

All examinations must have been completed within a period of 18 months of the initial Theoretical Knowledge Examinations taken. This is as required by FCL.025(b)(2), of UK Regulation (EU) No 1178/2011, whether taken with an EASA Member State, as a mix of EASA Member State Theoretical Knowledge Examinations and CAA Theoretical Knowledge Examinations.
