Start with Why: Clarifying Your Motivation and Needs
Knowing how to choose a psychotherapist starts with knowing why you want therapy and what you need from it.
At Mill Hill Counselling, we have 17 years of experience helping people who arrive at that first meeting with a vague sense of being stuck.
Start by writing down three things: what brought you here now, what you have already tried, and what a good outcome would look like.
Identifying the Concern You Want Help With
The concern you bring to therapy shapes everything that follows: the approach, the specialist, and the length of treatment. Anxiety, depression, trauma, relationship difficulties and longstanding patterns of emotional dissatisfaction each point toward different kinds of work.
Some questions to sit with:
Is this a recent crisis, or a pattern that has repeated for years?
Does it show up mostly in relationships, at work, or when you are alone?
Have you had therapy or counselling before, and what helped or did not?
If you have tried short-term counselling and found it useful but incomplete, that is itself useful information. It often points toward longer, more in-depth work rather than another round of the same thing.
Pro Tip Write your answers down and keep them. A therapist can work with a clear account of your concern far more effectively than with a feeling you cannot quite describe. If it helps, read your notes aloud before your first appointment.
How to Choose a Psychotherapist: Matching Approach to Your Needs
The right approach is the one that fits your concern, your personality and your appetite for depth. There is no universally best therapy, and any practitioner who claims otherwise is worth a second look.
Psychotherapy is a structured, ongoing conversation with a trained professional that uses a specific theoretical approach to help you understand your thoughts, feelings and behaviour. The approach matters because it determines what you talk about, how often you meet, and how long the work is likely to take.
Therapy Modalities: CBT, Psychodynamic, Person-Centred
Cognitive behavioural therapy focuses on the link between thoughts, feelings and actions.
Psychodynamic and psychoanalytic therapy looks at how earlier experiences and unconscious patterns shape your current life.
Person-centred therapy puts your own frame of reference at the centre of the work.
Approach | Typical Focus | Suits People Who | Usual Shape |
CBT | Present-day thoughts and behaviours | Want structured, goal-focused work | Weekly, often 6-20 sessions |
Psychodynamic | Unconscious patterns and early experience | Want to understand recurring difficulties | Weekly, open-ended |
Person-centred | Your own experience and self-direction | Want a non-directive, supportive space | Weekly, flexible length |
Most therapists are trained in one main modality but draw on others where useful. Ask directly which approach they would use with you and why.
A Practical Way to Match Approach to Concern
Rather than choosing a modality in the abstract, work backwards from what you want to change:
A specific, recent problem (panic attacks, a phobia, mild to moderate low mood), a structured, goal-focused approach such as CBT is usually the sensible first port of call.
Longstanding patterns that repeat across relationships or jobs, a longer, exploratory approach such as psychodynamic therapy is often more suitable.
A need to be heard without being directed, person-centred or integrative work may fit better than a manualised protocol.
Trauma or complex grief, look for a therapist with specific post-qualification training in trauma-focused work, not just general experience.
If you have tried one approach and found it useful but incomplete, that is itself useful information. It often points toward longer, more in-depth work rather than another round of the same thing.
Online or In Person: A Format Decision, Not an Afterthought
Format affects fit as much as modality does, and it is worth deciding deliberately rather than by default.
In-person suits people who value a dedicated physical space, find it easier to concentrate away from home, or want to read body language closely. It requires travel time and, in some areas, limited local availability.
Online (video or telephone) removes travel and widens your choice of specialist considerably, which matters if you need a therapist who understands a specific issue, language or identity. It requires a private, quiet space and a reliable connection.
Hybrid arrangements, mostly online with occasional in-person sessions, are increasingly common and can work well for open-ended therapy.
Ask any prospective therapist how they handle confidentiality online: which platform they use, whether sessions are recorded, and what happens if the connection drops. A practitioner who has thought this through will answer without hesitation.
Therapist Qualifications and Registration: What to Verify
Checking that a therapist is properly qualified and registered is the fastest way to separate a professional from someone offering an unregulated service.
Verification takes about ten minutes and is worth every second:
Ask which professional body the therapist is registered with.
Ask for their registration number.
Check the number directly on the body's public register, not on the therapist's own website.
Confirm their training, qualification and years in practice.
Ask whether they hold accreditation, which usually requires a minimum number of supervised clinical hours.
The main UK bodies maintain searchable registers, and the Professional Standards Authority's accredited register list shows which registers it oversees. If a therapist cannot or will not give you a registration number, treat that as a serious warning sign.
Watch Out The titles "psychotherapist" and "counsellor" are not protected in law, so a certificate on a wall proves nothing by itself. If you skip the register check, you may end up paying for sessions with someone who has no recognised training or supervision.
Questions to Ask a Therapist Before Starting
A short, direct set of questions before you commit will tell you more than any profile page. Most therapists expect them and answer them readily. If they seem irritated by the questions, that is information too.
What training and qualifications do you have, and where did you train?
Which professional body are you registered with, and what is your registration number?
Which approach do you mainly work with, and how does it fit my concern?
How often would we meet, and is the work open-ended or time-limited?
How do you handle confidentiality, and what are the limits to it?
The confidentiality question matters more than most people realise. The British Association for Counselling and Psychotherapy's ethical framework sets out the standards members work to.
How to Know If a Therapist Is Right for You
The therapeutic relationship is a significant factor in a good outcome, alongside the modality and the therapist's reputation. How understood, safe, and challenged you feel can be very important.
Signs the fit is working:
You feel able to say the awkward thing rather than editing yourself.
The therapist explains what they are doing and why.
You leave sessions with something to think about, even when they are uncomfortable.
You feel challenged without feeling judged or dismissed.
Signs it may not be:
You find yourself performing or managing the therapist's feelings.
Sessions drift without direction, week after week.
You feel worse in a way that never settles or is never discussed.
A common mistake is treating discomfort as failure. Good therapy is often uncomfortable, because it touches what you have been avoiding. The difference is whether the discomfort feels purposeful and contained, or whether it feels like being mishandled.
How to Review Progress Over Time
Fit is not a one-off judgement. It is worth revisiting at set points, because early impressions can be misleading in both directions.
Sessions 1-3: focus on whether you feel safe enough to be honest. Progress at this stage is about engagement, not symptom change.
Sessions 4-6: look for a shared understanding of what you are working on and why. If you cannot describe the goals in your own words, raise it.
Around session 12: for time-limited work, this is a natural review point. For open-ended work, ask yourself whether the sessions still feel purposeful.
Ongoing: a useful question every few months is whether you could explain to a friend what you are working on and what has shifted.
Concrete signs of progress include: noticing a pattern before it fully plays out, tolerating a feeling you used to avoid, handling a familiar situation differently, or simply being able to talk about something you could not previously name.
How to Raise a Concern or End Therapy Well
If something is not working, say so. Therapists expect this, and a good one will treat it as useful material rather than a personal criticism.
A simple way to raise it:
Name the observation, not the verdict: "I've noticed the last few sessions have felt a bit directionless to me" rather than "this isn't working."
Ask for their view: "Is that something you've noticed too?"
Say what you need: more structure, a different focus, or a clearer sense of where the work is heading.
If you decide to stop, you are not obliged to give a reason, but a final session to review the work is usually worthwhile and is standard practice. Ask whether a referral to a colleague with a different approach might suit you better, many therapists will offer one.
Key Takeaway Judge the fit over the first three to six sessions, not the first one. First meetings are nerve-wracking for almost everyone, and a shaky start says little about whether the work will help. Then review deliberately at around session 12 and every few months after that.
Red Flags in Therapy: When to Walk Away
Some behaviour is not a matter of fit and should end the relationship immediately. Trust your reaction, and remember that you are free to stop at any time and to ask for a referral elsewhere.
Clear red flags:
Any sexual, romantic or exploitative behaviour, which is a serious breach of every professional code.
Breaches of confidentiality without your consent or a legal duty.
Judgemental, dismissive or shaming responses to what you bring.
Sessions that consistently overrun into personal chat about the therapist.
Pressure to continue when you have said you want to stop.
No registration, no supervision, and no willingness to discuss either.
If you experience any of these, you can raise it with the therapist's professional body. The UK Council for Psychotherapy's complaints guidance explains how to do that and what to expect.
Conclusion
Finding the right therapist takes a little homework and a willingness to be honest about what you actually need. If you are tired of circling the same relationship patterns and want to understand what drives them, that is exactly the work we do.
Frequently Asked Questions
What should I look for when choosing a psychotherapist?
Look for a practitioner with relevant qualifications, professional registration, and experience treating your specific concern. Check that they are accredited by a recognised body and have trained in a modality that suits your needs. It is also important to feel comfortable and understood during your first meeting. Trust your instincts about the therapeutic relationship, as research consistently shows that a good fit predicts better outcomes.
How many sessions should I try before deciding whether therapy is a good fit?
Most practitioners suggest committing to at least three to five sessions before judging whether the therapy is working. The first session is largely an assessment, so it is difficult to gauge the full benefit from one meeting. If after several sessions you still feel unheard or the approach does not resonate, discuss it with your therapist or consider trying someone else. Openness to changing therapist is a sign of good self-care, not failure.
What are red flags in therapy?
Red flags include a therapist who breaks confidentiality without a clear safeguarding reason, makes inappropriate personal disclosures, or pushes their own agenda rather than listening to you. Other warning signs are persistent lateness, forgetting appointments, or a lack of empathy. If you feel unsafe, judged, or pressured, address it directly. If the behaviour continues, it is reasonable to end therapy and look for a better fit.
How can I verify a therapist's qualifications and registration?
Ask which professional body they are registered with and check that body's online register. In the UK, reputable psychotherapists and counsellors are often listed with organisations such as the British Association for Counselling and Psychotherapy (BACP), the UK Council for Psychotherapy (UKCP), or the British Psychoanalytic Council (BPC). You can also request details of their training, supervision arrangements, and insurance. A qualified professional will answer these questions openly and without hesitation.
