How Many Therapy Sessions Will I Need?
Uses your browser’s own voice. Nothing is sent to us.
In short: It depends on the therapy and what you need. The NHS says many talking therapies for depression last 8 to 16 sessions, guided self-help 6 to 8, and some specialist treatments up to 40 weeks. In private practice, the number is agreed between you and your practitioner, and it helps to review progress regularly.

Private Therapy
Private practitioners usually agree a plan with you after a first session or assessment. Some offer short, focused work over a set number of sessions. Others, such as many psychotherapists, also offer open-ended or longer-term therapy. Questions to ask:
- How many sessions do you expect we'll need, and why?
- How often will we meet, and how long is each session?
- When will we review how it's going?
- How do we decide to finish, and can I come back later?
- What is the fee for each session, and what is your cancellation policy?

Occupational Therapy, Physiotherapy and Speech and Language Therapy
For occupational therapists, physiotherapists and speech and language therapists, the number of sessions usually follows an assessment and depends on your goals. Some people need a short block, others regular sessions over months, sometimes with exercises or activities to do between sessions. Ask the practitioner what they expect after the assessment.
When to Review or Stop
It's fine to ask how things are going at any point. If therapy doesn't feel helpful after a few sessions, talk to your practitioner about it, or consider someone else. See when therapy isn't working.
