In reply to IlonaIlona77777:
Yes/No
NO: There is no legal requirement to have a special certificate
YES: *IF* you want to actually get work employed by someone else (especially in a gym) or get insurance you need to get a basic certificate. This used to be called "REPS" (Register of Exercise ProfessionalS) and people still sometimes call it that, but since 2020 you need CIMSPA membership. Take a look down this page at the different categories https://www.cimspa.co.uk/join-us/membership-for-individuals/
Maybe they can answer if your existing certificates are recognised by them. Be aware this is not a legal thing - you won't serve time in prison for performing unlicenced Yoga it's more as established practice here to get work
Ask them Email: info@cimspa.co.uk
Good luck
