I am a chartered H&S professional who is looking for new opportunities, I've worked at the same employer for a number of years with very little paid for professional development other than CPD. I have asked to do the 45001 lead auditor course with no luck for funding, so I'm considering paying for it myself. 

but just wondering if there are other courses I should think about before paying out so much money for this?

Do I do a level 4/6 fire course, (I have level 3) do I move more to leadership and management, 

suggestions please, I work for a local authority.
