How long will it take for my application to be processed?



We are currently working within the published service levels of 10 working days for all application types. Where an application is pended, the working days to process the application will be counted from the date of receipt of the requested additional information.

For a small number of applications, a licensing officer may require additional guidance which requires a referral to be made to a technical officer. The technical officer will review the case within 5 working days, however if further advice is needed this will be reviewed at a bi-weekly complex case review session. In such cases therefore the application will take longer to process than our standard turnaround times.

If your application is urgent, you can request that we expedite it. However, we will only expedite applications in extreme circumstances. All other applications will be processed in strict date order.

Expedite requests must be submitted in writing to customerservices@caa.co.uk and must be submitted by your Approved Training Organisation (ATO) or employer. We will not accept any expedite requests over the phone or directly from an applicant.

For further guidance please refer to our guidance on processing of applications.
