I’ll answer for her…. No. Physiotherapist and Physical Therapist are now protected titles meaning that anyone using the title must have completed training to a minimum of degree level and be registered with the Health Professions Council (HPC), which is equivalent to the old term of State Registered. They will also, as you say, have Member of the Chartered Society of Physiotherapy (MCSP) after their name.
These regulations could be seen as more rigorous than those of the osteopaths and chiropractors as these profession both regulate themselves, whereas the HPC is a regulator set up to monitor currently 13 health professions.
