How Long Does Therapy Take? Realistic Timelines for CBT and EMDR
One of the most common questions I’m asked before a first session isn’t about what therapy involves. It’s how long it will take. It’s a fair question, and the honest answer is: it depends. Here’s what “it depends” actually means in practice.
Cognitive Behavioural Therapy (CBT)
CBT is generally the more structured, time-limited of the approaches I use. For a single, clearly defined difficulty, a specific phobia, or a discrete pattern of anxious thinking, meaningful progress is often possible within roughly six to twelve sessions. More complex or longer-standing difficulties, or where several issues are intertwined, typically take longer. CBT works well within a defined timeframe because it’s built around identifying a specific problem and working through it systematically, so we’ll usually have a rough sense of scope after the first couple of sessions.
EMDR
EMDR timelines vary more, because they depend heavily on what’s being processed. A single, more recent traumatic incident can sometimes be processed in a small number of sessions. Trauma that’s more longstanding, repeated, or rooted in childhood, sometimes called complex trauma, usually needs more time, partly because early sessions focus on building safety and stabilisation before any reprocessing work begins. That’s not a sign that therapy isn’t working. It’s a necessary foundation.
What actually determines the timeline
A few things matter more than the specific approach: how long the difficulty has been present, whether there’s one clear issue or several overlapping ones, how much support exists outside of sessions, and the pace that feels right for you. Therapy isn’t a race, and going carefully, particularly with trauma work, is often what makes it effective rather than what slows it down.
What I can offer at the start
At an initial appointment, we’ll talk through what’s brought you to therapy and I’ll give you my honest, working estimate of what’s involved, while being upfront that it’s a starting estimate rather than a fixed contract. We’ll review progress together as we go, and you’re always free to ask at any point how things are tracking.
Once you decide to continue after that first appointment, you’ll get access to my calendar to book your own rolling appointments, which you can amend up to three days beforehand. It’s worth booking ahead where you can, since slots do get taken quickly, and it’s your responsibility to arrange these in good time. If a particular time is in high demand and you can’t find a slot, let me know and I’ll try to accommodate you.
If you’re weighing up whether to start, the timeline uncertainty shouldn’t be the thing holding you back. It’s something we work out together, early on, and revisit as needed.
