CAA Update: Introducing UK SORA Guidelines
Explore the UK SORA and learn how to transition smoothly.
UK SORA is the new framework, replacing OSC methodology on April 23, 2025;
Current OSC-based Operational Authorisations will remain valid until the expiry date;
PDRA-01based Operational Authorisations are not impacted by the introduction of UK SORA;
UK CAA says that UK SORA will make risk assessments for UAS operators more transparent and consistent;
The Authority adds that the new digital UK SORA Application Service is designed to deliver a more streamlined application process;
heliguy™ has an in-house training team and regulatory specialists who can provide more information and help with UK SORA applications.
The UK SORA (Specific Operation Risk Assessment) Application Service has gone live (as of Wednesday, April 23, 2025).
It means that the UK SORA methodology has now replaced the Operating Safety Case (OSC) methodology for Operational Authorisations for missions in the Specific Category.
If you have a current OSC-based Operational Authorisation (OA), it will remain valid until its expiry date. Variations to OSC-based Operational Authorisations will also be possible until the expiry date.
UK SORA does not impact current PDRA-01 holders or new PDRA-01 applications. PDRA stands for Pre-defined Risk Assessment. It is the alternative method to apply for an Operational Authorisation.

How UK SORA Differs from OSC
The UK CAA says that UK SORA will make risk assessments for UAS operators more transparent and consistent, while the new digital UK SORA Application Service is designed to deliver a more streamlined application process.
The table below provides a quick overview.
Streamlined Application Process | The UK SORA uses an online digital application service, guiding applicants through each step of the process. |
Less Subjectivity | Unlike the qualitative OSC methodology, SORA takes a more quantitative approach, ensuring greater consistency and transparency in evaluations. |
Two-Phase Process | Applicants no longer need to provide all assurance evidence upfront, making it easier to manage the application requirements. |
Mitigation Calculator | The SORA platform includes a calculator to assess required mitigations before proceeding with the full application. |
The UK SORA Application Service is a new service and there are some small cosmetic and functionality improvements that the UK CAA will continue to make after launch.
What is UK SORA?
As of April 23, 2025, UK SORA replaced the CAP 722A Operational Risk Assessment method - also known as the Operating Safety Case - as the way to apply for an Operational Authorisation.
UK SORA is based on the internationally recognised SORA 2.5 methodology developed by the Joint Authorities for Rulemaking on Unmanned Systems (JARUS). UK SORA is adapted to be suitable for the UK.
How to apply?
You can apply using the UK SORA-based Application Service.
This Service provides a structured way for you to provide your risk assessment to the UK CAA.
Once approved, the Operational Authorisation will last for 12 months. Operators can reapply from 28 days before their authorisation expires.
What does it mean for current holders of an OSC-based Operational Authorisation?
Existing OSC-based Operational Authorisations will remain valid until their expiry date. Variations to OSC-based OAs will also be possible until the expiry date. If you want to apply for a new OA, you will need to use the UK SORA Application Service or agree an alternative means of compliance with the UK CAA.
Transition arrangements for current OSC holders
If you want to reapply for your authorisation, the transition arrangements depend on when your current OSC-based Operational Authorisation expires.
Authorisation expires before July 22, 2025
Make a new application after 23 April using the UK SORA-based Application Service.
Authorisation expires between July 23, 2025, and August 31, 2025
If your current authorisation expires between July 23, 2025, and August 31, 2025, the CAA says it will contact you to discuss a reapplication.
In this case, you should make a new application on or after April 23 using the UK SORA-based Application Service.
Authorisation expires after August 31, 2025
If your current authorisation expires after August 31, 2025, the CAA says it will contact you in the months before it expires to discuss your reapplication. In most cases, you'll need to make a new application using the UK SORA-based Application Service.
What About PDRA-01 OAs?
PDRA-01 OAs are not impacted by UK SORA and will remain valid under the existing framework until further notice. While under review, no changes are expected before 31st March 2026.
PDRA stands for Pre-defined Risk Assessment.
Remote Pilot Competency (RPC) Updates
The Remote Pilot Competency (RPC) policy is being updated to support UK SORA. Operators will gain access to advanced training through Recognised Assessment Entities (RAEs), depending on the complexity of operations.
The GVC will remain available, with the required competence level dictated by the operation's complexity.
Recognised Assessment Entities – Flightworthiness (RAE(F))
RAE(F)s are external organisations that validate technical compliance for UK SORA applications. They are particularly useful for high-complexity operations requiring greater assurance.
Operators can opt to work with RAE(F)s to expedite application processing, with fees applicable for their services.
SAIL Marked UAS
SAIL (Specific Assurance and Integrity Level) marks align drones with predefined safety levels under UK SORA. A SAIL Mark, validated by an RAE(F), reduces the amount of technical evidence required in applications.
While optional, this concept can significantly speed up the application process for operators using compliant UAS models.
