Asking how much rehab costs, for most people, arrives at the point where treatment has moved from something they’re considering to something they’re seriously weighing. The answer can have a direct bearing on what happens next.

Castle Craig is transparent about the cost of treatment. The price depends on the individual programme – its length, the level of clinical support required, and the accommodation involved. What it includes is clearly set out, because cost and value need to be understood together to make a properly informed decision.

Whether you are asking for yourself or for someone in your life, this page covers what residential treatment at Castle Craig costs, what that covers, and the options available for funding it.

Addiction treatment at Castle Craig

Since 1988, we’ve been committed to offering the highest-quality care

“I feel like this experience has been life changing for me, this will help me continue with my sobriety. I couldn’t stop on my own, I am very grateful to Castle Craig.”

How much does private rehab cost in the UK?

Private inpatient rehab in the UK typically costs from £650 to £1,500 per day, or around £18,000 to £40,000 per month. Prices vary with the length of stay, the intensity of the programme, and the level of clinical care provided.

At Castle Craig, rehab cost is based on the programme your clinical team recommends for you. A shorter stay with a standard programme will cost less than a longer stay with more intensive support. Your admissions case manager can give you an accurate figure based on your situation.

When comparing the cost of alcohol rehab or drug rehab between clinics, look at what’s actually included in the price. Some programmes include detox, therapy, and aftercare. Others charge separately for each.

  • Inpatient vs outpatient rehab: what’s the cost difference?

    Inpatient rehab costs more than outpatient because of the level of clinical support provided. You live on site with around-the-clock medical care and a structured daily programme.

    Outpatient programmes cost less because you attend sessions during the day and return home afterwards. 

    For some people, that’s the right level of support. But for others, particularly anyone with more established dependence or co-occurring mental health conditions, the structure and clinical support of inpatient rehab can make a real difference.

How can you pay for rehab?

There are three main routes to how to pay for addiction rehab, and our admissions team will help you work out which options are available to you.

  • Self-funding

    If you’re self-funding, you can typically be admitted within 24 hours, with no insurance constraints or waiting lists. It’s the most flexible route, and it gives you full control over the length and type of your programme.

  • Private health insurance

    Castle Craig works with most major private health insurers. If you have health insurance coverage, our team can help you check what your policy includes and manage the process with your provider.

  • NHS-funded spaces

    NHS-funded places at Castle Craig are available but limited. You apply through your local authority or health board, and waiting times vary. If you’re exploring this route, we can explain the process and help you understand what’s involved.

What happens when you get in touch

When you, or someone in your life, is ready for treatment – we know how urgent that can feel. The process can look like:

Initial Contact with Our Admissions Team

Initial contact with our admissions team
The first step is to call our admissions team. During this call, they’ll ask you some questions about your situation and take you through a pre-admission assessment. 

There’s no obligation at this stage, but it’s a good opportunity to discuss which payment option suits you best.

Pre-Admission Screening

We run through a 20-minute questionnaire with all patients as part of our admissions process. This gives us more information about your mental health, your physical health, and your history. 

We also request details of your medical history from your GP. If contacting your GP isn’t possible, we’ll help find another way to get the information we need.

Receiving pre-admission information

After your initial assessment, we’ll send you a pre-admission information pack. This covers the treatment process, what to expect, and how to prepare. 

Our team will also help arrange your transport to the facility.

Communication with your doctor

We’ll send a letter to your GP to let them know you’re at Castle Craig for treatment. If additional medical information is needed, our Consultant Psychiatrist or another clinician may contact your GP directly.

Is the cost of rehab worth it?

People who don’t get the right support the first time are more likely to need treatment again. And the longer dependence continues, the more harm is done to careers, relationships, health, and future prospects.

Castle Craig has been treating addiction since 1988. That experience has shown us how much difference the right treatment makes. Our programme reflects everything we’ve learned people need to stay well, from medical detox through to aftercare.

If you’re weighing up the cost, a free assessment is the best way to find out what treatment would involve and what it would cost. Find out more about addiction rehab at Castle Craig.

Frequently asked questions about how much rehab costs

  • Does it cost more to treat drug addiction than alcohol addiction?

    At Castle Craig, the drug rehab cost and the alcohol rehab cost are the same. Both are based on the programme and the length of stay rather than the substance.

  • How much does rehab cost with private health insurance?

    The amount covered depends on your insurer and your policy. Some insurers cover the full cost of inpatient treatment. Others cover part of it, or specific elements like detox or therapy. Our admissions team can check your policy and explain what’s covered before you make any decisions.

  • Can I spread the cost of rehab with a payment plan?

    Castle Craig does not offer payment plans. Payment in full must be made before treatment begins.
