PfCO stands for 'Permission for Commercial Operations' and its granted by the CAA- The Civil Aviation Authority (yep, the drone industry loves its acronyms!)

If you want to use a drone in the UK for commercial purposes, it's a legal requirement that you have a PfCO. For more information and how to apply, head over to the CAA's Permissions and Exemptions webpage:
