Hi Elodie
It depends if you want to have your course nationally recognised.
There is no nationally accredited training course regarding Wedding Planner Training. However you may undertake an Event Management course which is nationally recognised within the industry. THere are a range of providers whom deliver this qualification
Alternatively you could complete a "certified" wedding course which may be written and delivered by people who have experience in wedding preparation and planning.
A couple of providers you may wish to contact are
