Indicative pricing

What private assessment and rehabilitation costs in the UK.

Indicative ranges across UK neuro-rehabilitation services.

In short

A structured inpatient assessment: £18,000–£45,000 over four to six weeks.

Service Indicative range
Rehabilitation medicine consultation £300–£600
Second-opinion diagnostic review £1,500–£3,500
Serial CRS-R / WHIM assessment block £2,500–£6,000
Structured inpatient assessment (4–6 weeks) £18,000–£45,000
Specialist neuro-rehabilitation, per week £3,500–£8,000
Best-interests / capacity report £2,000–£5,000
Case management set-up £1,500–£3,000

Costs vary by unit, by the length and intensity of assessment, and by whether ongoing rehabilitation follows. Many families fund this through NHS continuing healthcare, health insurance, or a personal-injury settlement coordinated by a case manager.

The problem

An accurate diagnosis, a realistic prognosis, and families kept informed.

This is where general services can fall short - a rushed diagnosis, reversible factors missed, and families left without a clear picture.

  • Assess properly, over time

    Signs of awareness are subtle and inconsistent. Repeated, validated assessment over weeks is the only reliable way to get the diagnosis right.

  • Rule out the reversible

    Sedation, seizures, infection and poor positioning can all mask awareness. These are checked and treated before any diagnosis is settled.

  • Support the decisions that follow

    An accurate diagnosis underpins best-interests decisions, including nutrition and hydration, made carefully under UK law.

When it helps

When a specialist service is the right step.

The situations that come up most, plus the one red flag that means urgent reassessment rather than a routine wait.

  • Severe traumatic brain injury

    A prolonged disorder of consciousness following major head injury, where specialist assessment clarifies the diagnosis and outlook.

  • Hypoxic-ischaemic brain injury

    Reduced consciousness after cardiac arrest or a period without oxygen, which needs careful, repeated evaluation over time.

  • Stroke or brain haemorrhage

    A severe bleed or large stroke leaving the person unresponsive or minimally responsive, requiring structured assessment.

  • Vegetative state (unresponsive wakefulness)

    Wakefulness without evidence of awareness - a diagnosis that must be confirmed carefully, as signs can be subtle.

  • Minimally conscious state

    Fluctuating but definite signs of awareness. Distinguishing this from vegetative state changes prognosis and care, and needs repeated testing.

  • Uncertainty needing a second opinion

    Where families or clinicians are unsure of the diagnosis, an independent structured review can confirm or revise it.

  • Best-interests and treatment decisions

    Support for difficult decisions, including clinically assisted nutrition and hydration, grounded in an accurate diagnosis and UK law.

  • Red flag: new signs of awareness or decline

    Emerging responses, or a sudden deterioration, warrant urgent reassessment - the diagnosis is never fixed and must be revisited.

What is assessed

The tools and the team behind an accurate diagnosis.

What the programme involves - validated assessments, careful screening for reversible factors, and a multidisciplinary team working to national guidelines.

  • Coma Recovery Scale-Revised (CRS-R)

    A validated, structured assessment repeated over time to detect and grade signs of awareness that a bedside examination can miss.

  • Wessex Head Injury Matrix (WHIM)

    A sensitive tool that tracks the sequence of behaviours as a person emerges from a disorder of consciousness.

  • SMART assessment

    The Sensory Modality Assessment and Rehabilitation Technique - a formal programme testing responses across the senses over several weeks.

  • Reversible-factor screening

    Reviewing sedation, seizures, infection, hydration and posture, because treatable factors can suppress responses and mimic a deeper disorder.

  • Neuroimaging review

    Careful review of CT and MRI, and occasionally functional imaging, to correlate structure with the clinical picture.

  • Multidisciplinary rehabilitation

    Physiotherapy, occupational therapy, speech and language therapy and neuropsychology working together to prevent complications and support any recovery.

  • Best-interests and legal support

    Guidance on decision-making under the Mental Capacity Act, including when the Court of Protection is involved in treatment decisions.

  • Long-term reassessment

    Planned review over months, because a proportion of people move from vegetative to minimally conscious states or beyond.

Safeguards and support

What to expect from the process - honestly.

Getting this right matters enormously. The things worth understanding are why assessment takes time, how misdiagnosis is avoided, and how decisions and families are supported.

  • Diagnosis takes time and repetition

    A prolonged disorder of consciousness cannot be diagnosed in a single visit. Repeated, structured assessment over weeks is essential and is what the guidelines require.

  • Misdiagnosis is a real risk

    Studies show a meaningful rate of misdiagnosis when informal assessment is used. Standardised tools and an experienced team reduce that risk substantially.

  • Reversible factors are checked first

    Sedative medication, seizures, infection, pain and poor positioning can all suppress responses. These are identified and treated before any diagnosis is settled.

  • Preventing complications matters

    Skilled nursing and therapy reduce pressure sores, contractures, chest infections and spasticity - problems that harm comfort and any prospect of recovery.

  • Prognosis is given honestly

    The specialist explains what the findings mean and what remains uncertain. Timeframes matter - outlook differs between traumatic and non-traumatic injury.

  • Decisions follow UK law

    Treatment decisions, including clinically assisted nutrition and hydration, are made in the person’s best interests under the Mental Capacity Act, sometimes with the Court of Protection.

  • The family is supported throughout

    Clear communication, time to ask questions, and psychological support are part of the service, not an afterthought.

  • The picture can change

    Some people transition to a minimally conscious state or emerge further over months. Planned reassessment ensures a diagnosis is never treated as permanent without review.

  • When to seek urgent review

    New responsiveness, seizures, breathing difficulty, fever or a sudden change in condition should prompt the specialist team promptly rather than a routine wait.

Reading the assessment report

The report in four parts. Read the last one first.

Whichever service carries out the assessment, the report your family receives keeps to the same shape.

A quiet reminder

Clinical and legal language can read coldly at a hard time - it is fine to ask for plain English.

It is reasonable to ask your clinician to talk your family through the assessment report and what it means before any meeting.

Frequently asked

Quick answers on diagnosis, recovery, decisions, cost and funding.

  • What is a prolonged disorder of consciousness?

    It is a state of reduced or absent awareness that continues for an extended period after a severe brain injury. It covers the vegetative state - now often called unresponsive wakefulness syndrome, where a person has sleep-wake cycles but no clear signs of awareness - and the minimally conscious state, where there are definite but fluctuating signs of awareness. The term is generally used once the state has lasted at least four weeks, and careful assessment is needed to tell these conditions apart.

  • Why can it not be diagnosed in a single assessment?

    Signs of awareness in these conditions are often subtle, inconsistent and easily missed at the bedside. UK national clinical guidelines therefore call for repeated, structured assessments over weeks using validated tools such as the CRS-R, WHIM and SMART. Reversible factors like sedative medication, seizures, infection or poor positioning are also checked and treated first, because they can suppress responses and make a person appear less aware than they are.

  • Can someone recover from a disorder of consciousness?

    Some people do improve, and a proportion move from a vegetative to a minimally conscious state or emerge further, particularly after traumatic rather than non-traumatic injury and especially within the first months. However, the longer the state persists the lower the likelihood of significant recovery, and outcomes vary widely between individuals. A specialist gives an honest, individual prognosis based on the cause, the imaging and the pattern of responses, rather than a general figure.

  • How are decisions about treatment made?

    When a person cannot make decisions for themselves, choices are made in their best interests under the Mental Capacity Act, taking account of any previously expressed wishes and the views of those close to them. Decisions about clinically assisted nutrition and hydration are made with particular care and, in some circumstances, are reviewed by the Court of Protection. An accurate diagnosis is the foundation of any such decision, which is why structured assessment matters so much.

  • How much does a private specialist assessment cost in the UK?

    A rehabilitation medicine consultation is typically £300–£600, and a second-opinion diagnostic review £1,500–£3,500. A structured inpatient assessment programme over four to six weeks generally ranges from £18,000 to £45,000, and ongoing specialist neuro-rehabilitation is around £3,500–£8,000 per week. A best-interests or capacity report is roughly £2,000–£5,000.

  • What is the NHS route, and how is care usually funded?

    The NHS provides specialist assessment and rehabilitation for disorders of consciousness, often through regional neuro-rehabilitation services, and NHS continuing healthcare frequently funds long-term care. Private input is most often sought for a timely second opinion, a structured assessment when local capacity is limited, or as part of a personal-injury settlement where a case manager coordinates care. Some costs may be met by health insurance or litigation funding.
