Group therapy on the NHS, and why you may be offered it

You refer yourself to NHS talking therapies, you get through the assessment, and then the offer arrives: not one-to-one sessions, but a group. A room (or a screen) of strangers, for weeks. If your stomach just dropped, that is a very ordinary reaction, and it is worth knowing what is actually being offered before you decide.

The short version

• The NHS says you may be offered the choice of group sessions or one-to-one, so a group is an offer, not an order.
• Groups tend to be structured courses with a set number of weekly sessions, not open-ended sharing circles.
• The research on group cognitive behavioural therapy (CBT) is encouraging, but it is thinner than the research on one-to-one, and the honest answer is that we do not know who does best in which format.
• You are allowed to ask questions, and to say that a group is the part you are dreading.

What a group usually involves

Services differ, so check your own, but the pattern is fairly consistent. The sessions are weekly and run for a set number of weeks. One NHS service runs courses of 6 to 8 weeks with 2 hour sessions, and longer group programmes of up to 12 weeks. Another describes 6 to 10 sessions. Some services run groups in person, some online.

These are usually taught, not therapeutic free-for-alls. Think of a course built on CBT skills, such as managing worry or understanding panic, with a workbook and exercises between sessions. One service states that you will not be asked to share your personal experiences with others, while others describe sharing as part of the point. Expectations differ, so it is a fair question to ask at the start.

Why you are offered one

Partly because of how services are built. NHS talking therapies often start with lighter-touch options: the NHS notes you may be offered guided self-help first, and in my view a group course is another way of teaching structured skills to many people at once. One service says plainly that group treatment comes with shorter wait times, which matters when the wait is the thing that hurts.

Partly it is because there is a genuine case for groups. One service says that meeting people who understand your experiences can reduce isolation, and that hearing how others approach similar challenges can reinforce your own strategies. For some people that matters a lot.

What the research does and does not show

I would like to be careful here, because the evidence gets overstated in both directions.

For social anxiety, a 2013 meta-analysis pooled 11 randomised trials with 654 participants and found that group CBT did better than control conditions (mostly waiting lists, with some pill placebo and usual care), with a moderate effect size (0.53). That suggests group CBT can help. It does not compare groups with one-to-one, and the authors flagged small numbers, variable study quality and limited intention-to-treat analysis.

For generalised anxiety disorder (GAD), a 2025 network meta-analysis compared CBT delivery formats across 52 trials and 4,361 people, but only 2 of those trials tested group CBT. It found no significant difference between group and individual CBT, and no significant difference in how acceptable people found the formats. The authors concluded that groups merit consideration as an alternative to individual CBT, and said the group findings should be treated with caution because so few trials tested them. They also found that remote CBT may be less effective.

So the fair summary is this: groups look like a reasonable option, not a consolation prize, but nobody can promise you that a group will suit you better or worse than one-to-one.

A group is a recognised way of delivering therapy. It is also fine to find the idea hard.

If a group feels like too much

Here is what I would do, in this order.

Ask what the group involves. How many people, how many weeks, whether you have to speak, whether cameras are on, what the sessions cover. Vague dread shrinks when it becomes a timetable.

Say what is putting you off. "I find groups very hard" is useful information for the clinician, not a refusal. They may be able to suggest a format with less pressure, or explain how others in your position have managed.

Ask about the alternatives. The NHS says you may be offered a choice, so ask whether one-to-one or guided self-help is available for you and how long the wait would be. Be aware that availability varies by area, and one service notes that one-to-one after a group may depend on a clinician's assessment of your needs and progress.

Weigh the wait. If a group starts in a few weeks and one-to-one is months away, you can start the group and still ask whether one-to-one is possible afterwards, though as above that may depend on a clinician's assessment. Your GP can also help if you feel stuck.

A note on session length

One NHS service runs its courses in 2 hour sessions. brightloaf's therapy is built around 20 minute sessions.

When to ask for help sooner

This is general information, not a substitute for personal medical advice. If your anxiety is severe, or you are having thoughts of harming yourself, do not wait for a course to start: speak to your GP, call NHS 111, or call 999 in an emergency. You can also call Samaritans free on 116 123 at any time. brightloaf is not a crisis service.
