There isn’t a single “average” ABI payout. Courts use the Judicial College Guidelines (JCG) to value pain and suffering, then add your financial losses. Current JCG ranges for brain damage run from ~£2,690–£15,980 for minor head/brain injury to ~£344,150–£493,000 for very severe brain damage; your total settlement can be higher once lost earnings, care, treatment and adaptations are included.
An acquired brain injury (ABI) can have devastating consequences, affecting every aspect of a person’s life. Unlike congenital brain injuries, which are present at birth, acquired brain injuries occur after birth and can result from accidents, medical negligence, assaults, or illnesses. The effects can range from mild cognitive difficulties to severe, life-changing disabilities requiring long-term care and support.
If you or a loved one has suffered an acquired brain injury due to someone else’s negligence, you may be entitled to claim compensation. Understanding how acquired brain injury compensation payouts are calculated and what factors influence settlement amounts can help you make informed decisions about pursuing a claim.
In this guide, we’ll explain what acquired brain injuries are, the common causes, how compensation is assessed, and what support compensation can provide for victims and their families.
What counts as an acquired brain injury?
An ABI is brain damage that occurs after birth from a traumatic cause (e.g., collision, fall, assault) or a non-traumatic cause (e.g., hypoxia, infection, stroke). Effects range from headaches and memory issues to profound cognitive, behavioural and physical disability. For medical guidance on symptoms and when to go to A&E, see the NHS page on head injury and concussion.
An acquired brain injury refers to any damage to the brain that occurs after birth. The injury can be traumatic or non-traumatic.
Traumatic Brain Injuries (TBI)
These occur when an external force causes damage to the brain, such as:
- Road traffic accidents
- Motorcycle accidents
- Cycling accidents
- Falls from height
- Workplace accidents
- Sporting injuries
- Physical assaults
Non-Traumatic Brain Injuries
These occur due to internal factors affecting the brain, including:
- Stroke
- Brain infections
- Lack of oxygen to the brain
- Brain tumours
- Medical negligence
- Poisoning or toxic exposure
Regardless of the cause, an acquired brain injury can significantly affect a person’s ability to work, communicate, maintain relationships, and carry out everyday activities.
How ABI compensation is calculated
Compensation usually has three parts:
- General damages – for pain, suffering and loss of amenity, valued using the Judicial College Guidelines (JCG). The 17th edition (Apr 2024) applied an average ~22% uplift for inflation, and says awards should be uprated for inflation between August 2023 and assessment.
- Special damages – your financial losses, for example:
- Past and future loss of earnings and pension
- Care and case management, paid or family
- Treatment and rehabilitation (neuro-rehab, physio, psychology)
- Travel, medication, equipment, home/vehicle adaptations
- Future needs – long-term care, therapies, aids, retraining and accommodation changes, where supported by evidence.
Because every ABI differs, “averages” are misleading. The JCG bracket + your documented losses is the realistic guide.
JCG guideline brackets for brain/head injury (England & Wales)
These are general damages only. Your final settlement may be substantially higher once financial losses and future needs are added.
| Injury category (JCG) | Typical description (short) | Guideline range |
|---|---|---|
| Very severe brain damage | Profound cognitive/physical disability, full-time care | £344,150–£493,000 |
| Moderately severe brain damage | Serious cognitive/behavioural deficits; substantial dependence | £267,340–£344,150 |
| Moderate brain damage | Problems with intellect, memory, work capacity; risk of epilepsy (wide sub-bands) | £52,550–£267,340 |
| Less severe brain damage | Good recovery but ongoing problems (concentration, mood, work) | £18,750–£52,550 |
| Minor head/brain injury | Minimal/short-lived symptoms; little/no permanent damage | £2,690–£15,980 |

Quick examples: turning brackets into real-world payouts
To estimate a total, add special damages to the JCG figure and consider future losses:
- Concussion with recovery in months:
General damages ~£4,000–£8,000 (inside “minor”) + lost wages for several weeks + a short course of physio and travel.
Indicative totals sometimes £6,000–£12,000, depending on proof. - Moderate ABI (can work again but with limitations):
General damages ~£90,000–£150,000 (within the “moderate” sub-bands) + months off work + neuro-rehab + some care support + vocational assistance.
Indicative totals often well into six figures. - Moderately severe/very severe ABI:
General damages £267,340–£493,000, plus lifelong care, accommodation changes, specialist equipment and high future earnings loss.
Seven-figure totals are possible where evidence supports lifetime needs.
What increases (or reduces) an ABI payout?
- Diagnosis & severity: Glasgow Coma Scale, loss of consciousness/PTA, imaging findings, and long-term neuropsychology results.
- Impact on independence: ability to work, manage finances, drive or live without support.
- Care needs: hours per week now and in future; case management and therapy.
- Symptoms over time: persistent headaches, fatigue, executive dysfunction, behavioural change and risk of epilepsy.
- Prognosis: whether further recovery is expected or plateaus.
- Inflation: the JCG’s 2024 ~22% uplift reflects recent price rises and should be kept under review to the assessment date.
Evidence Needed for an Acquired Brain Injury Claim
Strong evidence is crucial when pursuing compensation.
Evidence may include:
- Medical records
- Brain scans and diagnostic reports
- Witness statements
- Accident reports
- CCTV footage
- Expert neurological assessments
- Financial records showing losses
- Employment records
The more evidence available, the stronger the claim is likely to be.
ABI facts you can use in your evidence
Clear evidence helps your claim. Keep a diary of symptoms, care and spending, and store receipts. ABI remains a significant UK health burden; Headway reported 335,409 UK hospital admissions for ABI in 2023–24 (about 919 per day). Documenting the work impact and daily living restriction is critical.
Time limits and capacity
Most personal injury claims must start court proceedings within three years of the accident or your date of knowledge. Different rules apply for children and those lacking capacity.
Where a brain injury affects mental capacity, a deputy (or a litigation friend during litigation) may act to protect the person’s interests. See GOV.UK guidance on becoming a deputy for someone who lacks capacity.
