Dealing with addiction can be incredibly tough both physically and mentally, especially with a drug addiction like heroin. Our multidisciplinary team of medical professionals can provide you with the help and support you need. Through specialised treatment for heroin addiction, we equip individuals with coping strategies for long-term recovery.
See below for information about heroin rehab in general, as well as the service we provide if you decide to choose Cassiobury Court as your heroin addiction treatment provider.
Are you suffering from a Drug or Alcohol Addiction and need help? Cassiobury Court is a leading UK-based expert in Private Drug and Alcohol Rehabilitation Treatment. Find out how we can help by getting in touch with our friendly team today.
Opioids, including heroin, were involved in 47.1% of drug poisoning deaths registered in England and Wales in 2024, the largest drug category involved. Heroin and morphine remain the single biggest contributor within that, with 1,415 deaths. A key contributing factor is that UK drug suppliers are increasingly cutting heroin with more dangerous synthetic opioids, including nitazenes, often without users’ knowledge.

Please contact our team today or fill out the enquiry form to find out further information about the heroin addiction treatment we offer.
While we might be able to identify some of the physical signs of heroin addiction and dependency, symptoms of heroin misuse can also manifest into behavioural and psychological signs. These can be difficult to pinpoint, especially if the individual struggles with other mental conditions alongside their addiction.
If you think that you or a loved one is suffering from a heroin addiction, it’s vital that you seek professional heroin rehab treatment.
Consistent heroin misuse can have a number of life-threatening effects such as opioid use disorder (OUD), infections as a result of sharing needles such as hepatitis B, C and HIV and acute heroin overdose.
As a CQC-registered organisation, Cassiobury Court is a residential drug rehab clinic offering private heroin rehabilitation programmes with ongoing medical support.
Unlike public healthcare, private rehab clinics mean no waiting lists and a care plan that’s suited to every individual. We have a vast range of alcohol and drug rehab programmes, such as our dedicated opioid rehab clinic.
From serious skin and dental conditions to a heightened risk of HIV through sharing needles. It is important that you or your loved one quits as soon as possible – heroin does kill.
Making the first step in getting help for a heroin addiction is often the hardest. At Cassiobury Court, we can offer free confidential advice on heroin addiction treatment options. Our staff are on hand to receive calls regarding support and further guidance at any time.
If you’re looking to discuss options for heroin addiction, call now on 0800 001 4070.
After an initial assessment, our admissions team will tailor your heroin addiction treatment around your needs and create a personalised care plan. This will provide a regimented structure throughout treatment.
If you’re looking for heroin addiction help for a family member, we offer a family referral service along with weekly family support groups to discuss your loved one’s progress.
While everyone’s recovery journey is different, at Cassionbury Court, we typically suggest 3 stages for heroin addiction treatment.
For most people, the first step at our heroin rehab clinic is a medically assisted detox. Detoxing from heroin can be a difficult process, with symptoms lasting for around 2 weeks after heroin was last taken.
Cassiobury Court is a residential rehab clinic that has a dedicated heroin detox programme. Here you’ll receive around-the-clock care from our medical staff and the option of prescribed medications to detox from heroin comfortably and safely.
When you start your detox for Heroin addiction, there are medications used to help you wean off heroin. These medications help to reduce cravings and withdrawal symptoms. It is important that this medical detox is carried out under the supervision of a trained medical professional.
Medications used include:
When your withdrawal symptoms start to decline, counselling and therapy sessions will begin. These sessions will explore the reasoning behind addictive behaviour and help identify the triggers.
Our rehab clinic boasts a number of evidence-based therapies such as:
We can also offer weekly family-based therapy sessions where friends and family can attend the clinic to help with your recovery process.
Therapy sessions are conducted by a qualified multidisciplinary team such as psychotherapists and psychologists. Therapy can be one-on-one with our resident therapist or within groups of other individuals who are recovering from addiction.
Once therapy sessions are completed, a bespoke relapse prevention plan as well as discharge planning is devised before you return home. Our clients are encouraged to contact Narcotics Anonymous once the detox and heroin rehab have finished for ongoing support.
Cassiobury Court offers a FREE 12-month aftercare package following the completion of our heroin rehab programme.
Our private residential rehab offers a home away from home, with comfortable accommodation across two floors and private gardens for you to get some much-needed peace.

Rehabilitation is considered to be the best treatment available for heroin addiction. Cassiobury Court gives you a place to stay that is free from the temptations. With support from our medical professionals, there is nothing enabling you to continue to use drugs.
The length of treatment varies on the severity of your addiction and how you respond to treatment. In some cases, the withdrawal symptoms that come with detox can be quite difficult to deal with and this could lengthen the time of recovery, but in other cases, this might not be the same and you might find that the detox phase isn't as difficult as some may find it. The length of time is fully dependent on how the individual copes with the programme designed for them.
For most, heroin rehab can be highly beneficial in maintaining sobriety. Not only does it allow individuals to detox without distractions, but with a comprehensive aftercare programme, we can go through coping strategies to help you tackle triggers and prevent relapse, ensuring you are supported every step of the way.
This will depend on the length of your stay. Detoxing from heroin can affect people in different ways, particularly with withdrawal symptoms, the time scale of which varies from person to person. Price may also be dictated by the number of medicines we prescribe.
A typical day at Cassiobury Court consists of a variety of treatments which could include a therapy session, relapse prevention techniques or work on the "12 steps" approach.
Cassiobury Park, which is located just a stone throw away from the clinic is the biggest public open space in Greater London. During your treatment, a member of our team will accompany you on a daily walk around the local area where you can get some fresh open air while enjoying the surrounding area.
At Cassiobury Court, we are a strong advocate for having family visits in rehab. We can arrange family visits to encourage a support system with your loved ones and so that they can see how well you’re doing.
We acknowledge that there are a number of different types of heroin and different ways that people can misuse it. The most commonly known types in the UK are brown heroin and medical-grade heroin known as Diamorphine. Every detail of your misuse matters in creating your personalised care plan, as it helps determine the best course of action for medically assisted detox and overall recovery.
Heroin can be snorted, smoked or injected. If you think a loved one is using heroin, it’s important to consider that there might not always be obvious signs such as heroin track marks from injecting.
Once your time with us is complete, you will receive 12 months of free aftercare as part of your addiction recovery. We also recommend our clients visiting support groups such as narcotics anonymous, as they will greatly improve your chances of a drug-free future.
Individauls suffering from Heroin addiction may have also developed underlying mental health conditions such as depression and anxiety. It is possible that the struggles of dealing with mental health conditions or vice versa may have contributed to the development of your addiction to Heroin.
We recognise these co-existing conditions as dual diagnosis and are able to address both heroin addiction and mental health disorders alongside each other through rigorous, evidence-based therapies.
During your stay in heroin rehab, we recommend that you take time off work during the recovery process. Taking yourself away from the outside world can help reduce the risk of relapse, as you are taken away from things that normally might trigger your substance abuse. Most jobs will allow time off for health reasons, as addiction is recognised as a serious health condition.
