The UK drone market has grown rapidly, and so has the number of operators offering commercial survey services. Not all of them are operating legally. Understanding what CAA authorisation means — and why it matters for your specific project — is important before you commission any commercial drone work.
The UK regulatory framework
All commercial drone operations in the UK are regulated by the Civil Aviation Authority (CAA). The regulations are set out in UK Regulation (EU) 2019/947, which establishes three operational categories — Open, Specific, and Certified — based on the risk profile of the operation.
Most commercial survey work falls into the Specific category, which requires the operator to hold a CAA Operational Authorisation (OA). This involves demonstrating competency, maintaining an operations manual, and having appropriate insurance.
What authorisation involves
- A CAA-accepted operations manual covering procedures, risk assessment, and emergency protocols
- A registered and qualified Remote Pilot — the A2 Certificate of Competency or GVC as a minimum
- Public liability insurance — at least £1m, though most professional operators carry £5m
- Registration of the operator with the CAA and appropriate UAS markings on the aircraft
- Compliance with airspace restrictions and notification requirements (NOTAM, ATZ permissions)
Why this matters for your project
If you instruct an operator who is not authorised, you are not just relying on their compliance — you may be accepting liability yourself. Commercial sites, in particular, have specific requirements from insurers and principal contractors. An unauthorised operator on your site could invalidate your own site insurance.
For operations near aerodromes, in restricted airspace, over crowds, or beyond visual line of sight, additional permissions are required. An experienced authorised operator will identify these requirements upfront and manage them as part of the engagement.
We handle all airspace notifications, ATZ requests, and NOTAM filings as standard. Every survey is planned in advance with reference to airspace restrictions, and we will advise you if a specific operation requires additional permissions or is not feasible.
How to verify an operator
Ask to see their CAA Operational Authorisation, their insurance certificate, and their operations manual or risk assessment for the specific job. A professional operator will provide these without hesitation. If an operator is reluctant to share any of these, treat that as a red flag.
