What Type of Brain Injury Was Reported?
Select the injury type recorded in the medical evidence. This does not set the compensation amount by itself.
Select the Brain Injury Severity Category
Choose a category supported by a medical diagnosis and long-term prognosis. Severity cannot be reliably determined from symptoms alone.
Choose the reported injury type
to display severity references.
Medical caution:
This calculator cannot diagnose brain
damage, measure cognitive impairment or
determine care requirements. Serious
symptoms following a head injury need
urgent medical assessment. Do not rely
on a compensation calculator to decide
whether medical attention is required.

How It Works
How Does the Brain Injury Compensation Calculator Work?
This brain injury compensation calculator provides a structured way to explore selected general damages references used in England and Wales. It separates the reported type of injury, the medical severity category and optional financial losses. The result is an arithmetic illustration based on the selected information, not a substitute for a medical or legal assessment.
Step 1: Choose the Brain Injury Type and Severity
Choose the reported injury type, such as concussion, traumatic brain injury or other acquired brain injury. The second question displays the relevant injury severity references. Medical experts consider cognitive ability, movement, communication, behaviour, recovery and independence when assessing actual severity.
Step 2: Add Documented Financial Losses
Enter lost earnings, medical and rehabilitation costs and care-related expenses if appropriate. This section is optional. Serious brain injuries may involve substantial future earnings, therapy and care expenses that need separate expert evaluation.
Step 3: Review the Final Calculation
The final screen reveals the detailed breakdown of the selected general damages reference and optional financial losses. Visitors can copy the result or return to edit the selection. No figure is presented as a guaranteed compensation award.
2026 Guideline References
Brain Injury Compensation Amounts UK
The following reported 2026 Judicial College Guidelines, 18th edition, categories concern general damages for pain, suffering and loss of amenity. They do not include care costs, rehabilitation or financial losses.
| Brain Injury Category | General Damages Reference |
|---|---|
| Minor Brain/Head Injury | £2,920–£16,870 |
| Less Severe Brain Damage | £20,240–£56,890 |
| Moderate Brain Damage (iii) | £56,890–£119,860 |
| Moderate Brain Damage (ii) | £119,860–£198,320 |
| Moderate Brain Damage (i) | £198,320–£289,420 |
| Moderately Severe Brain Damage | £289,420–£372,570 |
| Very Severe Brain Damage | £372,570–£533,720 |
Important:
The ranges are not a diagnosis
or a fixed compensation tariff.
Moderate brain damage is split
into three subcategories reflecting
different degrees of continuing
disability. Expert medical evidence
is required to identify the
appropriate category.
Types of Brain Injuries
Common Types of Brain Injuries
Brain injuries can affect memory, concentration, movement, behaviour, communication and independence. The long-term impact varies significantly between individuals.
Traumatic Brain Injury
A traumatic brain injury can follow a collision, fall or blow to the head. Effects range from temporary symptoms to permanent neurological disability.
Post-Concussion Symptoms
Some people experience persistent difficulties with memory, concentration, sleep or headaches. Medical assessment is important for ongoing symptoms.
Moderate Brain Damage
Moderate brain injuries may cause continuing cognitive or physical restrictions, reduced capacity for work and changes to daily functioning.
Severe Brain Damage
Serious brain injury may lead to substantial dependence, communication difficulties or long-term medical and care needs.
Acquired Brain Injury
Acquired brain injury describes brain damage arising after birth, including traumatic and non-traumatic causes. Claim eligibility depends on the legal circumstances.
Compensation Explained
How Is Brain Injury Compensation Calculated?
Where legal responsibility is established, compensation may include general damages for the injury and special damages for losses resulting from it.
General Damages
General damages reflect the injury and its effects on quality of life. Cognitive, physical and behavioural limitations, prognosis and dependence on care may matter.
Special Damages
Financial losses may include earnings, medical treatment, care, rehabilitation, assistive equipment, accommodation changes and travel expenses where legally recoverable.
Future Financial Needs
Severe injuries can involve lifelong support or earnings losses. Proper valuation may require medical, care and financial experts, rather than a basic online calculator.
Valuation Factors
What Affects Brain Injury Compensation?
Brain injury compensation is particularly dependent on the evidence about long-term function, rehabilitation, prognosis and care. Two injuries with the same initial diagnosis may have very different lifelong consequences.
Cognitive Impairment
Memory, attention, concentration, learning ability and decision-making difficulties may affect the severity assessment. Detailed neuropsychological evidence can be relevant.
Physical Disability
Balance, coordination, movement, fatigue or other neurological difficulties may limit daily activities and independence. Medical reports may help assess whether these limitations are likely to improve.
Behaviour and Communication
Changes in mood, personality, communication or behaviour may significantly affect relationships and the ability to participate in daily life.
Employment and Earning Capacity
A brain injury can prevent a return to previous work or reduce the person's earning capacity. Future losses may require expert vocational and financial assessment.
Care and Rehabilitation Needs
Some people need ongoing physiotherapy, occupational therapy, psychological support or personal care. Severe cases may require extensive long-term planning.
Worked Example
Example Brain Injury Compensation Calculation
Suppose medical evidence supports the less severe brain damage reference category, and the person has £5,000 in assumed legally recoverable financial losses.
| Calculation Component | Amount |
|---|---|
| Less Severe Brain Damage | £20,240–£56,890 |
| Lost Earnings | £2,500 |
| Medical and Rehabilitation | £1,500 |
| Care and Other Costs | £1,000 |
| Total Financial Losses | £5,000 |
| Illustrative Combined Range | £25,240–£61,890 |
The example adds £5,000 to both ends of the selected guideline reference. It excludes any unassessed future care, rehabilitation or earning capacity losses. It is not a prediction of an actual case settlement.
Supporting Evidence
What Evidence Is Needed for a Brain Injury Claim?
Brain injury claims can involve detailed medical and functional evidence. The documentation required depends on the injury, the legal circumstances and the losses being claimed.
Hospital and Neurology Records
Emergency department records, neurological assessments, imaging and hospital notes may help establish the nature of an injury.
Neuropsychological Evidence
Cognitive assessments can provide information about memory, attention and other difficulties affecting everyday functioning.
Rehabilitation and Care Reports
Therapy records and assessments of support needs may help document rehabilitation requirements and care costs.
Accident and Financial Records
Incident evidence, witness statements, work records, invoices and receipts may be relevant to liability and financial losses.
Legal Information
Can You Claim Compensation for a Brain Injury?
A brain injury may form part of a claim following a road traffic accident, workplace incident, fall or alleged medical negligence. A diagnosis alone does not establish legal entitlement to compensation. Responsibility, causation and supporting evidence must be considered.
Road Traffic Accidents
Drivers, passengers, cyclists, pedestrians and motorcyclists may sustain traumatic brain injuries during collisions. Liability depends on the circumstances of the accident.
Accidents at Work
Falling objects, unsafe working environments and falls from height may result in head or brain injuries. Relevant safety obligations and evidence are important.
Public Place Accidents
Slips, trips and falls may cause head injuries. Legal responsibility must be established rather than assumed from the accident.
Medical Negligence
Some brain injuries arise in medical contexts. The assessment may involve different questions of professional duty, breach and causation.
Claim Time Limits
Many negligence-based personal injury claims in England and Wales normally have a three-year limitation period, with important exceptions. Capacity and childhood can affect applicable rules.
Frequently Asked Questions
Brain Injury Compensation Calculator FAQs
How much compensation can I claim for a brain injury?
There is no standard amount. General damages depend on injury severity and long-term effects. Financial losses may be recoverable separately where supported by evidence and law.
How much compensation is available for a minor brain injury?
The reported 2026 guideline reference for minor brain or head injury is £2,920–£16,870. An actual assessment depends on medical evidence and recovery.
Can I use the calculator for a concussion?
Yes. The tool includes a concussion option and a minor injury reference. It cannot determine whether continuing symptoms qualify for a more serious category.
What is the compensation reference for severe brain damage?
The reported 2026 reference for moderately severe brain damage is £289,420–£372,570, while very severe brain damage is £372,570–£533,720.
Does brain injury compensation include future care costs?
Future care can be relevant to an actual claim, but it normally requires detailed medical and financial assessment. This calculator does not independently project future care needs.
Can I include rehabilitation and lost earnings?
Yes. Step 2 allows documented lost income, medical costs, rehabilitation and care expenses to be entered. Actual recovery depends on evidence and law.
Why does the result initially display £0.00?
The initial £0.00 is a display placeholder, not a compensation valuation. The reference updates after a supported injury category is selected.
Is the brain injury compensation estimate guaranteed?
No. The calculator provides an illustrative reference. Brain injury severity, future needs, liability and actual claim value require specialist assessment.
