You could look for massage therapists with a Level 3 Diploma in Massage or Complementary Therapies
. The Council for Soft Tissue Therapies (GCMT)
is the governing body for massage therapy and recommends that all massage therapists have taken a full or part-time course.
Before you choose a massage therapist, you could read testimonials and read details of their services on their website.
You could also look at their profile page on Bark and read massage reviews from past customers too. This might also help you get some ideas for the type of massage you want to book.
