I am registered with CNHC.
The CNHC is the national voluntary regulator for complementary healthcare practitioners in the UK. It was set up with government support and its main aim is to enhance public protection by setting standards which must be met in order for practitioners to be able to register.
Some private health cash plans will reimburse for CNHC registration. (Look for more information on the CNHC site and discuss with the healthcare company first.)
