You seem unsure about your objectives regarding training. Do you detect a skills gap that needs filling or are you concerned about a formal qualification to provide evidence of the compitency you already have?
In terms of whether you should go ahead without training, surely that would be most unwise if you recognise you dont possess the skills for the job. You certainly should not go ahead if health and safety issues are involved, the implications of which you may not fully appreciate.
Formal qualifications are essential in the longer term if you wish your organisation to be perceived as a professional organisation. For the individual they of course engender self esteem and create a pride in the job.
