How much does it cost?

The C of A Fee Calculator for non-Part 21 aircraft provides details on current charges.

In the event of a discrepancy between the information here and the Official Record Series 5, CAA Scheme of Charges (Airworthiness, Noise Certification and Aircraft and Aircraft Engine Emissions), the Scheme of Charges takes precedence.

Payments can be made by credit or debit card or by bank transfer made payable to the Civil Aviation Authority.

When using bank transfer, make sure you identify what the payment is for by including:

  • the aircraft registration
  • the application type (for example, National ARC issue)
  • the receiving department

Additional charges

If the cost of our investigations exceeds the application charge payable, there will be additional charges to recover those excess costs incurred by the Civil Aviation Authority (CAA) in accordance with the Scheme of Charges.

The balance for the excess hourly charge (total hourly charge less initial charge already paid) is payable to the CAA and will be invoiced to you.
