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.

Changes in the physical characteristics of the aerodrome including the erection of new buildings and alterations to existing buildings or to visual aids require prior approval by the CAA, as specified in aerodrome licence conditions.

The CAA has developed a 3-stage process to assist aerodromes and ensure that aerodrome operators meet their obligations under their respective regulation.

This process should be used for all changes requiring prior approval. It is acceptable to submit Parts 1 and 2 together.

The submission process consists of 3 separate parts:

  • Part 1: Compliance
  • Part 2: Control
  • Part 3: Completion

Changes that require prior approval from the CAA should be submitted using SRG 2006 and to developments@caa.co.uk 


Each development proposal should be accompanied by documentation that provides clear evidence that the proposal conforms to licensing requirements detailed in CAP 168 Licensing of Aerodromes and other applicable Civil Aviation Publications.

In order to demonstrate to the CAA that the project will be managed safely, the CAA will expect the aerodrome to develop safety assurance documentation that describes how they will manage the construction works and operating procedures, to ensure that aerodrome operations can continue safely during the project.

How much does it cost?

Please note that some changes (e.g. major developments) may incur a charge. For details please see our Scheme of Charges.
