In short
- NICE recommends cognitive behavioural therapy (CBT) that includes exposure and response prevention (ERP) as the core psychological treatment for adults with OCD.
- For milder OCD, NICE suggests starting with lower-intensity CBT including ERP, up to around 10 hours of therapist time, such as guided self-help, brief individual work or a group.
- For moderate OCD, NICE offers a choice between more intensive CBT with ERP or a course of SSRI medication, and recommends combining both for severe OCD.
- Exposure and response prevention means gradually facing what triggers your OCD while resisting physical or mental compulsions, and it should always be agreed with you.
The National Institute for Health and Care Excellence (NICE) publishes evidence‑based guidance on how conditions should be treated in the UK. If you’re living with OCD, it’s useful to know what it recommends, whether you’re seeking help through the NHS or privately.
The headline: CBT with ERP
For adults with OCD, NICE recommends cognitive behavioural therapy (CBT) that includes exposure and response prevention (ERP) as the core psychological treatment.
ERP involves gradually facing the thoughts, images and situations that trigger your OCD, while resisting the compulsions (physical or mental) that usually follow. It is carefully graded and should always be agreed with you. Over time, the anxiety reduces and the OCD loses its grip.
How much therapy?
NICE takes a “stepped” approach based on how much the OCD is affecting your life:
- Milder difficulties: NICE suggests starting with lower‑intensity CBT including ERP, up to around 10 hours of therapist time. That might be guided self‑help, brief individual work or a group.
- If that isn’t enough, or for moderate difficulties: a choice between more intensive CBT including ERP (more than 10 therapist hours) or a course of SSRI medication, which NICE considers comparably effective.
- Severe OCD: a combination of CBT including ERP and an SSRI.
These are guidelines, not rules. Everyone’s OCD is different, and the right amount of therapy depends on you.
Where medication fits
SSRIs (a type of antidepressant) can help with OCD and are sometimes used alongside therapy. Medication is a decision to make with your GP or psychiatrist. As a counsellor I don’t prescribe, but I’m happy to work alongside your GP with your consent.
What this means if you’re looking for help
When choosing a therapist for OCD, it’s reasonable to ask:
- Do you use exposure and response prevention?
- How do you decide where to start, and how fast to go?
- How will we know if it’s working?
A good therapist will be able to explain their approach clearly and will never spring exposures on you.
How I work with OCD
I’m trained in ERP and use it at the core of my work with OCD and intrusive thoughts, including “Pure O” and harm OCD. We spend time understanding your OCD first, build a ladder together, and you choose where to start. Alongside the structure, there’s always room to talk about the shame and exhaustion OCD can bring.

Common questions
Do I need medication for OCD?
Not necessarily. NICE suggests starting with lower-intensity CBT including ERP for milder OCD. SSRIs can help and are sometimes used alongside therapy, and medication is a decision to make with your GP or psychiatrist.
How many hours of therapy does NICE recommend for OCD?
NICE suggests up to around 10 hours of therapist time for milder OCD and more than 10 hours for more intensive work. These are guidelines, not rules, and the right amount depends on you.
Will ERP make me face my worst fears straight away?
No. ERP is carefully graded and should always be agreed with you. A good therapist will explain their approach clearly and will never spring exposures on you.
