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.


Organisations needing to change a Registered Company or Limited Liability Partnership (LLP) Number will require a new initial approval as it cannot be classed as a change to an existing approval.

The Civil Aircraft Airworthiness Information and Procedures (CAAIP) - Leaflet C-30 (CAP 562) provides further information.


The list of Official Record Series 5 explains the Civil Aviation Authority (CAA) Scheme of Charges.

If you apply for a change to an approval with multiple ratings under the same approval type, you must include a payment relating to the charge for the highest rating applied for, for example, a Part 147 application for ratings T1, T2 and C would attract a single charge for the highest rating, being the T1, as per the Scheme of Charges.

In the event of a discrepancy between the information here and the Official Record Series 5, Civil Aviation Authority (CAA) Scheme of Charges takes precedence.
