How often should you have therapy? 4 factors that decide

Most people should start with weekly sessions while the working relationship is still forming, then move to fortnightly or monthly once things feel steadier. That’s my honest, personal answer, and it’s a starting point, not a rule. The right frequency for you depends on what you’re bringing to therapy, how you respond early on, and what you can realistically sustain. There’s no universally “correct” number of sessions a week, whatever some websites imply. This post walks through what actually decides it, what the research on session frequency shows, and what to do if weekly isn’t financially possible.

Key takeaways

• Weekly sessions early on tend to build the therapeutic relationship faster and lead to quicker symptom relief, particularly in the first two to three months.
• Once you’re through the early phase, moving to fortnightly or monthly sessions doesn’t undo progress for most people — it’s a normal, sensible next step, not a downgrade.
• Consistency matters more than raw frequency. Sporadic sessions with long unplanned gaps slow things down far more than a slightly lower but regular frequency.
• If cost is the barrier, less frequent but regular sessions (say, monthly) beat stopping altogether or attending erratically.
• Certain presentations — acute crisis, active trauma processing, recent bereavement — usually benefit from staying weekly for longer before spacing out.
• Your therapist should revisit frequency with you periodically. It’s a collaborative decision, not something fixed at intake and never mentioned again.

Why do most therapists suggest starting weekly?

Starting weekly gives the therapeutic relationship room to form quickly, and that relationship is one of the strongest predictors of whether therapy actually works. A comparison of weekly and fortnightly therapy trajectories found that weekly sessions led to more early improvement and shortened how long people spent in distress, compared with fortnightly sessions over the same stretch of time (full study). A separate trial comparing once-weekly against twice-weekly CBT and interpersonal therapy for depression found that the higher-frequency group had roughly half the drop-out rate and a faster reduction in symptoms in the early months, although that gap narrowed by two years post-treatment (study details).

There’s also a well-known, if dated, finding from Howard and colleagues’ 1986 research on the “dose-effect” relationship: roughly half of clients in their dataset showed measurable improvement by session eight, with further gains slowing down after that (original paper). That study is nearly forty years old and has been challenged since — more recent work argues the curve looks different once you account for people who simply feel “good enough” and stop attending on their own terms, rather than everyone improving at the same rate (2020 systematic review). What both old and new research agree on is the broad shape of it: change tends to be more concentrated early on, which is a decent argument for having more frequent sessions while you’re building trust and momentum with your therapist.

What actually determines how often you should have therapy?

It comes down to four things: what you’re working through, how you’re responding early on, what you can sustain financially and practically, and how the relationship with your therapist feels. None of these sit still — they shift over the course of the work, which is exactly why frequency should be reviewed rather than fixed.

What you’re working through. Acute crisis, active trauma processing, or a recent bereavement usually call for staying weekly for longer. Long-standing patterns like people-pleasing, low self-esteem, or working through identity and self-acceptance often tolerate more spacing once the initial groundwork is done — the work is slower by nature and doesn’t always need the intensity of weekly contact to keep moving.

How you’re responding. If you’re leaving sessions with things to sit with, feeling like the last conversation is still doing something in the background, that’s often a sign the current frequency is working. If you find yourself repeating the same ground every time because too much has happened in between, that can be a sign the gap is too long.

What you can sustain. Private counselling in the UK typically runs somewhere between £40 and £80 for a 50-minute session, with the British Association for Counselling and Psychotherapy noting that more than half of therapists listed on its directory advertise fees in the £40–£60 range (BACP fee data). At that rate, weekly sessions add up to somewhere between roughly £170 and £350 a month. That’s a genuine barrier for a lot of people, and it’s one of the main reasons frequency isn’t a one-size-fits-all recommendation.

How the relationship feels. Frequency is partly a function of trust. Early on, more contact helps that trust build. Later, once you know your therapist and know the shape of your own process, longer gaps between sessions don’t threaten the relationship the way they might have done at the start.

Is fortnightly or monthly therapy actually enough?

Yes, for most people, once the early relationship-building phase is done. This isn’t a compromise position — it’s how a lot of long-term therapeutic work is actually structured. The research above on frequency comparisons was almost entirely conducted in the first months of treatment; it says very little about whether someone six months into an established relationship needs weekly contact to keep progressing, and in my experience, most don’t. What matters more at that stage is that sessions stay regular rather than sporadic. A gap of two or three weeks with a plan behind it is a completely different thing from a gap of two months because life got busy and nobody put a note in the diary.

If finances are the reason you’re considering less frequent sessions, that’s a completely legitimate reason on its own, not something to apologise for. A monthly session you can actually afford and keep to will do more for you than a weekly session you can’t sustain and end up cancelling.

How long does a typical course of therapy last, and does that change with frequency?

It varies hugely depending on what you’re working on, but shorter, more frequent phases followed by longer, spaced-out ones is a common pattern. I’ve written more on this specifically in how long counselling usually takes, which covers typical timelines in more depth than makes sense to repeat here. As a rough shape: some people come for a defined block of weekly sessions to work through something specific, then stop. Others start weekly, move to fortnightly, then monthly, and keep an ongoing but low-frequency relationship going for years as a kind of check-in. Both are valid uses of therapy — one isn’t “more serious” than the other.

Frequency options compared

What if I can only afford therapy occasionally?

Say so, honestly, at the start. A good therapist would rather structure something sustainable around your actual budget than have you attend for six weeks and then vanish because the cost caught up with you. This might mean starting less frequently than would be ideal in a perfect world, and that’s fine — irregular but honest is better than an unsustainable plan you abandon. It’s also worth knowing that online counselling tends to sit at the lower end of the private fee range without the evidence suggesting it’s less effective for most concerns, which can make more frequent sessions more affordable if in-person isn’t a requirement for you.

If you’re working through something that involves your nervous system directly — trauma responses, hypervigilance, that sense of being permanently braced — session frequency interacts with how your body processes what comes up in the room, which I go into more in trauma-informed therapy. That’s one area where I’d be more cautious about recommending you space sessions out too early.

Frequently asked questions

Is once a week enough for therapy?

For most people starting out, yes. Weekly sessions early on give the relationship room to build and tend to produce faster initial improvement than less frequent contact. Once things stabilise, many people move to fortnightly or monthly without losing ground.

Can I switch from weekly to fortnightly partway through?

Yes, and it’s a normal, common shift rather than a sign you’re “doing it wrong.” It’s worth naming with your therapist directly so you can both keep an eye on whether the new frequency is still working for you.

Does less frequent therapy mean slower results?

Not necessarily. It usually means a different pace, particularly for longer-standing patterns rather than acute crises. Regularity tends to matter more for outcomes than the specific interval, as long as gaps are predictable rather than accidental.

What counts as “too infrequent” for therapy to work?

There’s no fixed cut-off, but long, unplanned gaps — months rather than weeks, with no session in between to process what’s happened — tend to undo continuity and mean more time gets spent catching up rather than moving forward. Monthly, kept to consistently, is very different from “whenever I get round to it.”

Should my therapist tell me how often to come, or is it my choice?

Both. It should be a collaborative decision that gets revisited, not a fixed instruction from day one or an open-ended question you’re left to answer alone. If you want to talk through what might suit you specifically, my about page has more on how I work, or you can get in touch directly.
