A head injury, however it happened, can change everything. Beyond the immediate medical shock, families often face months or years of adjustment: lost income, altered personalities, and care responsibilities that nobody planned for. Where someone else caused or contributed to the injury, a compensation claim can help cover the costs of recovery, rehabilitation, and the practical support needed to move forward.
This guide walks through what a head or brain injury claim looks like in England and Wales, the kinds of incidents that commonly lead to claims, and the stages involved in seeking a settlement. It is written for people trying to get their bearings after something serious has happened, whether that is to them personally or to someone they love, and who want a straightforward explanation before they make any decisions about what to do next.
Overview
A head or brain injury claim is a civil claim for financial compensation brought against the person, company, or organisation whose negligence caused the harm. The claim is made through the civil courts under the law of negligence, though the vast majority settle without ever reaching a trial.
Compensation in these cases is usually broken down into two parts. The first is what lawyers call general damages, which covers the injury itself, the pain it has caused, and the loss of enjoyment of normal life. The second is special damages, which covers measurable financial losses such as lost earnings, medical treatment, travel to appointments, adaptations to the home, and the cost of care, whether that care is paid for or provided unpaid by family members.
Brain injury claims sit at the more complex end of personal injury law because the long-term effects can be difficult to predict, and medical evidence often needs to build up over time before the full value of a claim becomes clear. Claims must generally be brought within three years of the injury, though different rules apply for children and for people who lack mental capacity.
Key steps
Get medical attention and keep records. The first priority is always proper medical treatment. Keep copies of hospital discharge notes, GP records, scan results, and any written communication from consultants. These records form the backbone of any later claim and also help the treating team track changes over time.
Work out who was responsible. Compensation depends on showing that someone else's negligence caused or contributed to the injury. This might be a driver in a road collision, an employer who failed to provide safe working conditions, an occupier of premises, or another party entirely. Write down what happened while it is fresh, and gather witness details.
Speak to an experienced legal adviser early. Brain injury claims involve complicated medical evidence and careful calculation of future losses. Getting practical perspective early on helps you understand whether you have a claim worth pursuing and what to expect, based on what you describe about the circumstances and the injuries sustained.
Build the evidence and obtain medical reports. A formal claim requires independent medical evidence, usually from consultants in neurology, neuropsychology, or rehabilitation medicine. Evidence of financial loss, such as payslips, receipts, and care diaries, also needs to be gathered. This stage can take many months in serious cases.
Negotiate a settlement or issue court proceedings. Most claims settle through negotiation once liability is accepted and the medical picture is clear. If the other side disputes the claim or makes a low offer, court proceedings can be issued. Interim payments may be available earlier to help with immediate costs.
Q How long do I have to start a head injury claim?
In England and Wales, the general time limit for personal injury claims is three years from the date of the injury, or from the date you first knew the injury was linked to someone else's negligence. For children, the three-year clock does not start until their 18th birthday. Where an injured person lacks mental capacity, the time limit may not run at all while that incapacity continues.
Q Can I claim if I was partly at fault for the accident?
Yes, in many cases. This is known as contributory negligence. If you were partly responsible, for example by not wearing a seatbelt or ignoring a safety instruction, any compensation awarded can be reduced by a percentage that reflects your share of the blame. Being partly at fault does not usually prevent a claim, but it can affect the final amount you receive.
Q What if the injured person cannot manage their own affairs?
Where a brain injury has left someone unable to make decisions for themselves, a claim can be brought on their behalf by a litigation friend, often a family member. Any settlement reached usually has to be approved by the court to make sure it is in the injured person's best interests, and the money may be managed through the Court of Protection.
Q Does compensation only cover the injury itself?
No. A well-prepared claim covers a wide range of losses. This includes the injury and its effects, lost earnings past and future, cost of care (including unpaid family care), medical treatment, rehabilitation, therapy, equipment, home adaptations, travel costs, and in some cases the cost of case management or deputyship. The aim is to put the injured person back, as far as money can, in the position they would have been in.
Q What counts as a minor head injury versus a serious one?
There is no strict legal definition, but the distinction usually comes down to the lasting effect on the person's life. A short concussion with full recovery sits at one end of the scale. A serious injury tends to involve long hospital stays, ongoing symptoms, an inability to return to previous work, or a need for care and support. The more lasting the impact, the higher the potential value of a claim.
Q Will I have to go to court?
Most personal injury claims, including brain injury claims, settle through negotiation without a trial. Court proceedings are sometimes issued to keep things moving or to put pressure on the other side, but even then, cases often settle before the hearing. Going to trial is the exception rather than the rule, though serious and high-value cases are more likely to reach that stage.
Q How is future loss of earnings calculated?
Future loss of earnings is calculated using a multiplier and multiplicand method set out by the courts. The multiplicand is the annual net loss, and the multiplier reflects how long the loss is expected to continue, adjusted using official tables. In complex cases involving career progression, promotion prospects, or pension loss, expert evidence from an employment consultant or forensic accountant may be needed.
Head and brain injury claims can be daunting to think about, especially when you are still dealing with the fallout of what happened. An experienced legal adviser can talk things through with you by phone and give you a practical perspective on your specific situation, based on what you describe.
