What is ocd?
OCD is characterised by obsessions — unwanted, intrusive thoughts, images or urges that cause significant anxiety — and compulsions, the repetitive behaviours or mental rituals performed to neutralise that anxiety. Common themes include contamination, checking, symmetry, and distressing intrusive thoughts about harm, relationships or morality. Far from being a quirk about tidiness, OCD can consume hours each day and cause deep shame, which often delays help-seeking for years.
OCD affects around 1–2% of the population and typically begins in late childhood or early adulthood. Diagnosis is made through clinical assessment by a therapist, psychologist or psychiatrist, supported by scales such as the Y-BOCS. It is very treatable: the majority of people improve substantially with the right therapy, medication, or both.
Common symptoms
- Intrusive, unwanted thoughts, images or urges
- Excessive washing or cleaning
- Repeated checking of locks, appliances or actions
- Mental rituals such as counting or silently repeating phrases
- Seeking reassurance repeatedly
- Needing things to feel 'just right'
- Avoiding situations that trigger obsessions
How long will you wait?
OCD can be referred through NHS talking therapies, with assessment often within weeks but waits for a full course of ERP-trained therapy commonly running to several months, and longer for specialist OCD services.
Privately, you can typically see an OCD-experienced psychologist or psychiatrist within 1–2 weeks.
NHS England median referral-to-treatment wait: 12.4 weeks, with 2.5 million people waiting over 18 weeks (May 2026). Individual waits vary by trust and urgency.
Treatment options
- CBT with exposure and response prevention (ERP). The gold-standard therapy, gradually facing triggers while resisting compulsions, with strong evidence of lasting benefit.
- SSRI medication. Antidepressants at OCD-effective doses, useful alone or combined with ERP.
- Clomipramine. An older medication option when SSRIs have not helped sufficiently.
- Specialist and intensive services. National specialist OCD services and intensive programmes for severe or treatment-resistant cases.
What does private treatment cost?
As a guide, private ERP-based CBT costs around £90–£180 per session, with an initial psychiatric consultation around £250–£400 where medication advice is needed.
Does health insurance cover ocd?
OCD treatment is claimed under mental health benefits, which differ markedly between insurers — some include outpatient psychology and psychiatry as standard, others only as an add-on, and session limits are common. Pre-existing OCD is usually excluded at the outset, and because OCD often requires more than a handful of sessions, check limits carefully. Recurrent claims may prompt chronic classification by some insurers.
Frequently asked questions
I have horrible intrusive thoughts — does that mean I'm dangerous?
No. Intrusive thoughts about harm, taboo subjects or acting out of character are a hallmark of OCD precisely because they clash with your values — that is why they are so distressing. People with OCD are not at increased risk of acting on these thoughts. Clinicians experienced in OCD understand this completely, so you can be honest in an assessment without fear of judgement.
What does ERP therapy actually involve?
ERP means gradually and voluntarily facing situations that trigger your obsessions — starting with easier ones — while resisting the compulsion that usually follows. With repetition, anxiety subsides on its own and the brain learns the feared outcome does not materialise. It is challenging but done collaboratively at a pace you agree, and it has the strongest evidence base of any OCD treatment.
Can OCD be cured?
Many people achieve a level of recovery where OCD no longer meaningfully affects their life, and symptoms can become minimal or absent. Some retain a vulnerability that flares under stress, but the skills learned in ERP mean setbacks can be tackled quickly. The realistic and hopeful message is that OCD is highly treatable, and improvement is the norm with proper treatment, not the exception.
