YES! Tavistock Relationships' therapists adhere to our professional code of ethical standards which includes the principle of confidentiality.
This means that we would not disclose information about you to a third party without your agreement, except in situations where there was significant concern about harm to you or someone else and this would normally be discussed with you beforehand.
If you come as a couple we would normally expect that information can be shared between you. If you have any questions about confidentiality you can discuss them with your therapist.
