If you are seeking a counsellor or therapist, I would generally recommend looking for someone who is Accredited with the BACP (British Association for Counselling and Psychotherapy). This organisation has a directory of practitioners. You might also consider the therapist directory of the UKCP (UK Council for Psychotherapy). It can be useful to have an informal phone discussion with any prospective therapists before committing to sessions. You might consider requesting an initial session to see whether you both feel that the therapeutic relationship would be a ‘good fit’. I hope that this helps.
