Discreet sex addiction rehab where you can be completely honest
Charterhouse Clinic offers residential rehab for sex addiction in a private Northamptonshire estate. Whatever has brought you here, our team has heard it before and treated it with the same care and empathy as any other addiction.




The isolating reality of a hidden compulsion
Sex and relationship addiction is one of the most difficult to talk about, which means most people carry it alone for far longer than they should. The weight of that isolation is often harder to bear than the behaviour itself. It is entirely treatable, and our rehab for sex addicts is a completely judgment-free zone.
Sex addiction needs more than willpower to overcome
At Charterhouse Clinic, our rehab for sex addicts provides the sustained clinical focus and safe distance needed for real recovery.
Sex addiction is rooted in attachment trauma and deeply ingrained patterns that need proper clinical intervention to shift. Trying to change from within the same environment that drives the behaviour is exceptionally hard.
Our sex addiction rehab combines trauma-informed therapy and CBT in a setting that gives the work the best possible chance of holding.
Sex addiction recovery gives you yourself back

Your privacy is fully protected
Nothing about your enquiry, assessment, or stay at Charterhouse Clinic is shared with anyone without your explicit written consent.
Your choices become your own again
Our rehab for sex addiction equips you with techniques to manage impulses and make deliberate, healthy choices.
Genuine intimacy becomes possible

For those in relationships, we provide structured support to begin repairing trust when the time is right.
