However, the main advantage of the GVC over the PfCO is that the GVC forms the 'base-line' training qualification and you can then complete 'bolt-on' training modules which will allow you to do things like;

Fly your drone 'EVLOS' ( Extended Visual Line of Sight)
Fly your drone 'BVLOS' ( Beyond Visual Line of Sight)
Fly your drone over crowds of people
Fly your drone over and within congested areas

The bolt-on modules aren't available from any provider at the time of writing (the CAA haven't finalised the 'PDRA's' that the Bolt-Ons are based around yet) but as soon as they do, then skies the limit.

Conclusion
The drone regulations in the UK are changing significantly and things are actually going to be much easier for people who want to enter the commercial drone market and make money from flying their drone.

That being said, there are a few important things to be aware of:

Make sure you have completed the CAA DMARES (Drone Registration)
Make sure you have insurance in place before flying your drone 'commercially'
Make sure you have the appropriate qualification if you want to fly closer than 150 metres to uninvolved people.
We've got other in-depth content which discusses the details of the CAA A2 C of C ( Certificate of Competency ) and the GVC but the main thing to note about the GVC is that the certificate which you get issued by your training provider is valid for 5 years and you'll use this to apply to the CAA for your Operational Authorisation each year.
