Does my registration with the HCPC have a post-nominal?

No. ‘MHCPC’ is not a recognised post-nominal and should not be used. The HCPC is neither a professional body nor a membership organisation, nor an educational awarding body. The HCPC is the state regulator for physiotherapists. Individuals who wish to use the protected title of ‘physiotherapist’ or ‘physical therapist’ must be registered with the HCPC. You are a registrant of the HCPC, not a member.
