What to Do When Your GP Has Never Heard of ERP. 11 Key Tips

Clinical disclaimer: This article is for informational purposes only and does not constitute clinical advice or a substitute for assessment by a qualified healthcare professional.

• ERP (Exposure and Response Prevention) is the NICE-recommended psychological treatment for OCD, but many GPs are not specifically trained in it and may not recognise the term.
• Your GP’s job is not to deliver ERP — it is to refer you to someone who can. You can ask directly for a referral to NHS Talking Therapies (IAPT) or a specialist OCD service.
• Bring a one-page summary of NICE guideline CG31 to the appointment so the conversation becomes a shared task rather than a debate.
• If the local NHS pathway is too generic, you can self-refer to NHS Talking Therapies in England, request a Step 3 high-intensity CBT therapist, or seek a BABCP-accredited private therapist.
• Not every CBT therapist competently performs ERP. Ask specific screening questions before starting therapy.

What you won’t find elsewhere Most articles on this topic stop at “ask your GP for a referral.” This one gives you the exact wording I use with clients (the Three-Sentence GP Script), a screening checklist for vetting whether a therapist actually does ERP properly, and an honest account of why so many primary-care clinicians have a blind spot for OCD treatment in the first place.

In my work with people with OCD over the past decade, the single most common roadblock I hear about isn’t symptom severity, motivation, or fear of treatment. It’s the moment a person finally sits in front of their GP, says the word “OCD,” and gets a blank look back when they mention ERP. If your GP has never heard of ERP, I want you to know two things straight away: it is not your fault, and it does not mean help is unavailable.

This article walks you through exactly what to do next.

Why your GP has never heard of ERP (and why it’s more common than you think)

ERP — Exposure and Response Prevention — is the gold-standard psychological treatment for OCD, but it lives inside specialist mental health training rather than general medical training. Most GPs have a few hours of mental health teaching across their entire qualification, and OCD is a relatively low-prevalence diagnosis compared to depression or generalised anxiety, so it tends not to be covered in any depth.

OCD affects roughly 1–2% of the population at any given time (Fawcett et al., 2020), which means a typical full-time GP might only see a handful of clearly diagnosed cases each year. Add to that the fact that OCD is frequently missed or misdiagnosed in primary care — particularly when the obsessions are taboo (sexual, religious, harm-related) rather than the stereotyped contamination presentation — and the diagnostic delay from first symptoms to correct treatment is often more than ten years (García-Soriano et al., 2014).

So when your GP looks puzzled, they are not being negligent. They are working at the edge of what general practice covers. The job now is to redirect the appointment toward the part they can do: the referral.

What ERP actually is, in plain English

Exposure and Response Prevention is a structured form of cognitive behavioural therapy in which you deliberately, gradually face the situations or thoughts that trigger your obsessions, while choosing not to perform the compulsion that usually neutralises the anxiety. Over repeated exposures, the brain learns that the feared outcome doesn’t happen, that the anxiety subsides on its own, and that you can tolerate uncertainty without ritualising.

The evidence base for ERP is one of the strongest in all of psychotherapy. Randomised controlled trials and meta-analyses consistently show large effect sizes, with response rates typically reported in the region of 60–80% for adults completing an adequate course of treatment (Öst et al., 2015). The UK’s National Institute for Health and Care Excellence recommends CBT, including ERP, as a first-line psychological treatment for OCD across all age groups (National Institute for Health and Care Excellence, 2005).

That last point matters for your appointment, because it means ERP is not an obscure preference — it is the treatment the NHS itself is supposed to be offering you.

What to say when your GP has never heard of ERP

Walk in with a specific request, not a general complaint. GPs respond well to clarity because their appointments are short and they have to make a routing decision in roughly ten minutes.

Here is the script I give clients. I call it the Three-Sentence GP Script:

1. “I think I have OCD, and the symptoms are affecting [work / sleep / relationships / specific area].”
2. “NICE guideline CG31 recommends CBT with Exposure and Response Prevention as the first-line psychological treatment.”
3. “Could you refer me to NHS Talking Therapies, or to a specialist OCD service if one is available locally?”

Three sentences. No history of childhood, no defending whether it’s “really” OCD, no apology for taking up time. You are giving the GP a problem and a clearly defined next step.

If they are unfamiliar with ERP specifically, that’s fine — they don’t need to deliver it. They need to refer you to the service that does. In England, you can also bypass the GP entirely and self-refer to NHS Talking Therapies (NHS, 2024).

What to bring when your GP has never heard of ERP

A printed one-page summary of NICE CG31’s recommendations, or the URL written down. This shifts the conversation from “do you believe me” to “here is what your own guideline says.” In my experience, GPs respond extremely well to this — it removes any sense of being challenged and provides them with documentation to include in their notes.

What if the referral I’m offered isn’t suitable?

This is where many people get stuck, and it’s worth being honest about. NHS Talking Therapies (formerly IAPT) is a stepped-care service. At Step 2, you will typically be offered low-intensity CBT delivered by a Psychological Wellbeing Practitioner, often through guided self-help. For mild OCD, that can be appropriate and effective.

For moderate to severe OCD, however, low-intensity work is rarely enough. NICE recommends Step 3 high-intensity CBT with ERP, delivered by a fully qualified CBT therapist (National Institute for Health and Care Excellence, 2005). If you are offered something less and your symptoms are significantly impairing your life, you can — and should — ask explicitly:

• “Can I be assessed for Step 3 high-intensity CBT with ERP?”
• “Is there a specialist OCD pathway in this area?”
• “If local services can’t provide ERP, am I eligible for an out-of-area referral?”

In England, severe and treatment-refractory OCD can be referred to one of the national specialist OCD services, although waiting lists are long. Your GP or NHS Talking Therapies clinician can initiate this.

A clinical vignette: when a GP has never heard of ERP, the cost of delay

I’ll share an anonymised composite based on people I’ve worked with, as it captures the pattern I see most often.

A man in his thirties — I’ll call him “James” — had been experiencing intrusive thoughts of harm toward his infant daughter for nearly two years before he saw his GP. He had never told anyone. When he finally went, he chose his words carefully and said he was having “anxiety about being a dad.” His GP, with the best intentions, prescribed an SSRI and signposted him to a generic mindfulness app. ERP was never mentioned because OCD was never identified.

By the time James reached me, eighteen months later, the avoidance had widened to the point where he was no longer bathing his daughter or leaving her alone. The treatment itself was not complicated — a standard course of ERP, with care taken around the harm theme and reassurance-seeking. He responded well. What stuck with me was the cost of those eighteen months: a near-relationship breakdown, time off work, and a deep belief that he was a dangerous person.

The lesson I take into every consultation is this: the people who most need ERP are often the ones whose obsessions sound most disturbing, which makes them the least likely to articulate them clearly to a GP. If that is you, please name the thoughts on the form or in the room, even briefly. Therapists who treat OCD have heard everything, and we recognise the pattern instantly.

How to tell if a therapist actually does ERP

This is one of the most misunderstood aspects of OCD treatment, and even experienced clinicians can get it wrong. “CBT for OCD” is not the same thing as ERP. A therapist may use cognitive techniques, behavioural activation, or general anxiety management and label the work CBT — without ever doing the structured exposure work that drives recovery in OCD.

Before you start therapy, ask the following five questions:

1. Are you BABCP-accredited, or working towards accreditation? BABCP is the lead UK accrediting body for CBT.
2. How many OCD cases have you treated using ERP specifically?
3. Will we build a hierarchy of feared situations and work through it together?
4. Do you support in-session exposures, including for taboo or harm-themed obsessions?
5. How do you handle reassurance-seeking and mental compulsions?

A therapist who does ERP well will answer these comfortably and concretely. If the answers are vague, or if the therapist suggests “we’ll just talk about why you feel this way,” that is a flag. Talk therapy alone is not ERP, and for OCD it tends not to produce lasting change (Skapinakis et al., 2016).

What to do while you wait for treatment

Waiting lists for high-intensity CBT can be long, and the gap between referral and first session is often where people lose hope. There are evidence-informed things you can do in that window.

Self-help books grounded in ERP principles — particularly those used as bibliotherapy in clinical trials — can produce meaningful symptom reduction in mild to moderate OCD (Tolin et al., 2007). The OCD-UK and International OCD Foundation websites maintain reading lists. Beyond that, the most useful thing you can do is begin to notice and name your compulsions without yet trying to stop them. Awareness is the foundation on which ERP is built, and people who arrive at therapy already able to identify their rituals tend to make faster progress.

What I would gently steer you away from is reassurance-seeking — including spending hours online searching for the “real” meaning of your thoughts. That activity is itself a compulsion, and it tends to entrench the problem (Abramowitz et al., 2009).

FAQs: When your GP has never heard of ERP

Is ERP the same as CBT?

No. ERP is a specific component of CBT used primarily for OCD and some anxiety disorders. General CBT may include cognitive restructuring, behavioural experiments, and other techniques. For OCD, NICE specifically recommends CBT that includes ERP (National Institute for Health and Care Excellence, 2005).

Can my GP prescribe medication for OCD instead?

GPs can prescribe SSRIs, which have a good evidence base for OCD, often at higher doses than for depression (Skapinakis et al., 2016). Medication and ERP can be used alone or in combination. NICE recommends offering both as options and discussing the choice with you.

How long does ERP take to work?

A typical NHS course of high-intensity CBT for OCD runs to around 16–20 sessions, though more complex presentations may need longer. Most people notice meaningful change within the first six to ten sessions if exposures are being attempted between appointments (Öst et al., 2015).

What should I do if my GP has never heard of ERP and refuses to refer me?

You can request a second opinion from another GP in the same practice, self-refer directly to NHS Talking Therapies in England (NHS, 2024), or seek a BABCP-accredited private therapist. You do not need GP permission to access private CBT.

Is ERP dangerous for people with harm or sexual obsessions?

No. ERP is the recommended treatment for these themes, not a contraindication. A trained ERP therapist will design exposures appropriate to the content. The fear that exposure will “make things worse” is itself part of the obsessional pattern, not a clinical risk (Abramowitz et al., 2009).

When to seek professional help

If your symptoms are interfering with daily functioning — work, relationships, sleep, self-care — please do not wait for things to get worse before reaching out. You can:

• Speak to your GP and request a referral, using the script earlier in this article.
• Self-refer to NHS Talking Therapies if you are in England.
• Use the BABCP register at cbtregistera.com to find a privately accredited CBT therapist.
• Visit OCD-UK or OCD Action for peer support and information about treatment pathways.

If at any point you are experiencing thoughts of harming yourself, contact 111, your GP, or the Samaritans on 116 123. OCD is highly treatable, and the right help is worth asking for more than once.
