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.



Complaints provide the CAA (Civil Aviation Authority) with a great opportunity to listen, learn and improve from what our customers tell us. Therefore, we are dedicating time and resources to understand where and how we can improve.

Every three months, you can view key performance information on this page, which shows how we are performing and what has been learnt from complaints.

Each year we will publish an Annual Complaints Report providing a more detailed look at our performance on complaint handling.

For more details on our 2022/23 performance please refer to our Annual Complaints Report 2022/23.
