This guide is reviewed against current UK statute, Judicial College Guidelines (18th edition, April 2026), and SRA guidance before publication. It is for general information only and does not constitute legal advice.
If someone else’s negligence caused your serious injury, you may be able to claim compensation for your physical and psychological harm, lost earnings, care costs, rehabilitation, and long-term needs. Serious injury claims in the UK are governed by a three-year time limit. Most cases run on a No Win No Fee basis, so there are no upfront legal costs to worry about. Specialist representation matters here, settlements in high-value cases can range from tens of thousands to several million pounds depending on the injury and its long-term impact.
A serious injury changes things quickly. What life looked like before may feel very far away, and the practical questions pile up fast. Can you still work? Who will pay for your care? What does the future look like for your family?
If someone else was responsible for what happened to you, the law provides a route to compensation that goes well beyond covering your immediate medical costs. A properly handled serious injury claim addresses lost income, long-term rehabilitation, care needs, and the broader impact on your quality of life.
This guide explains how serious injury claims work in the UK, what compensation may be available, and what you should do next.
What counts as a serious injury?
In legal terms, a serious injury is one with long-term or life-changing consequences, permanent symptoms, ongoing treatment needs, or a significant reduction in independence or earning capacity.
An injury that causes long-term physical, psychological, or functional impairment, often requiring specialist medical evidence and complex financial modelling to value correctly. Includes traumatic brain injuries, spinal cord damage, amputations, and severe psychiatric harm.
Courts and insurers distinguish between injuries that heal in weeks and those that fundamentally alter someone’s life. Serious injuries fall into the second category. They often involve permanent symptoms, require adapted living arrangements, and affect the injured person’s ability to work, sometimes forever.
Common serious injury types that can support a claim include:
- Traumatic brain injuries (TBI), including diffuse axonal injury and intracranial haemorrhage
- Serious head injuries with post-traumatic complications
- Spinal cord injuries, including paraplegia and tetraplegia
- Multiple or complex fractures
- Amputations and crush injuries
- Severe burns covering significant body surface areas
- Internal organ damage
- Serious psychiatric injury, including PTSD, linked to trauma
These are not minor inconveniences with fixed recovery windows. Many will shape what the injured person can do, earn, and enjoy for the rest of their life.
How much is a serious injury claim worth?
Compensation depends on injury severity and financial impact. Brain injury general damages alone can reach £493,000 under the Judicial College Guidelines 18th Edition (April 2026). Special damages covering care, lost earnings, and rehabilitation can raise total awards substantially higher.[1]
General damages cover the injury itself: pain, suffering, and loss of amenity. Special damages are evidenced by financial losses, lost earnings, care costs, medical treatment, home adaptations, mobility equipment, and travel expenses. In catastrophic cases, special damages often exceed general damages by a significant margin.
Every serious injury claim has two financial components. General damages address the injury and its impact on your daily life. Special damages cover the money you have lost, or will lose, as a direct result of what happened to you. In life-changing cases, that second category can run into hundreds of thousands or even millions of pounds over a lifetime.
| Injury Type | Severity | Typical Range | Recovery / Notes |
|---|---|---|---|
| Brain / head injury | Very severe | £344,150 – £493,000 | Full dependency; intensive lifetime care |
| Brain / head injury | Moderately severe | £219,070 – £344,150 | Significant cognitive/physical disability |
| Brain / head injury | Minor | Up to £15,580 | Full recovery expected |
| Spinal / back injury | Most severe | £120,340 – £212,670 | Permanent disability with ongoing care |
| Psychiatric injury | Severe | Significant 5–6 figure sums | Impacts all aspects of daily life |
| Special damages | All | 100% of evidenced loss | Lost earnings, care, rehab, adaptations |
Figures are indicative general damages based on the Judicial College Guidelines 18th Edition (April 2026). Every claim is assessed on its own facts. Please verify figures with a qualified solicitor before relying on them.

Can you get compensation before the claim settles?
Often, yes. An interim payment is money paid on account of your final compensation while the claim is still running. In serious injury cases it is commonly used to fund treatment, adapted equipment, care or housing changes that cannot wait for the case to finish.
Serious injury claims take time, and the costs of a life-changing injury start immediately. Interim payments exist to close that gap. They are not a separate pot of money: whatever is paid is deducted from the final settlement.
In many cases the defendant’s insurer agrees to make interim payments voluntarily, particularly once responsibility has been accepted. Where they will not, the court can be asked to order one.
When the court can order an interim payment
The rules are in Part 25 of the Civil Procedure Rules. The court can only order an interim payment where one of the conditions in rule 25.23 is met:
- the defendant has admitted liability to pay damages;
- you already have judgment against the defendant for damages to be assessed; or
- the court is satisfied that, if the claim went to trial, you would obtain judgment for a substantial amount against that defendant.
The third is the one most often argued. It does not require the case to be proved, but the evidence has to show that a substantial award is likely. The application must be supported by evidence setting out the sum claimed, the losses already incurred and expected, and the medical evidence.
When the court can order an interim payment
- private treatment, therapy or rehabilitation that is not available quickly on the NHS
- a wheelchair, prosthetics or other equipment
- adaptations to a home, or the cost of moving to suitable accommodation
- care and support, including paying a family member who has given up work
- replacing lost income while you are unable to work
What happens about rehabilitation?
Rehabilitation usually runs alongside the claim rather than after it, and in many serious injury cases the defendant’s insurer contributes to the cost. It is considered early and separately from the question of who was at fault.
This is one of the clearest differences between a serious injury claim and an ordinary one. Recovery does not wait for a legal argument to finish, so the two run in parallel.
The framework for this is the Rehabilitation Code, a voluntary code used by claimant solicitors and insurers. The usual sequence is an early assessment of what you need by an independent case manager, followed by agreement between the parties on what will be funded. The assessment is confidential and is not used as evidence of what your claim is worth.
The Serious Injury Guide
Separately, APIL and FOIL publish a Guide to the Conduct of Cases Involving Serious Injury, which signatory firms and insurers apply to claims valued at £250,000 or more. It does not cover clinical negligence or asbestos-related disease, which have their own arrangements.
Where it applies, it commits both sides to things that are not in the standard pre-action protocol:
| Commitment | What it means for you |
|---|---|
| Notification within 7 days | Your solicitor notifies the insurer within seven calendar days of being instructed, rather than waiting until the evidence is complete. |
| Early engagement | Both sides talk before proceedings are issued, which can shorten the case considerably. |
| Early interim payments | The insurer contributes early toward disbursements and costs, which funds the evidence your claim needs. |
| Rehabilitation considered | Rehabilitation is addressed alongside the Rehabilitation Code, with a case manager appointed jointly where both sides agree. |
| Negotiation before formal offers | The parties negotiate before any Part 36 or time-limited offer is made, so you are less likely to face a deadline-driven offer early on. |
| An escalation route | Where a case stalls, it can be escalated to senior case handlers rather than drifting. |
The guide is voluntary and not every insurer has signed up to it, so it is worth asking early whether it applies to your case.
How is serious injury compensation paid out?
Either as a single lump sum, or partly as a lump sum and partly as periodical payments, which are index-linked payments made for life or for a set period. For future financial losses the court can order periodical payments without either side agreeing to them.
For most injury claims this question never arises, because a lump sum is the obvious answer. In a catastrophic injury claim where care will be needed for decades, how the money is paid matters as much as how much it is.
Lump sum or periodical payments
| Lump sum | Periodical payments |
|---|---|
| One payment at settlement | Regular index-linked payments, often for life |
| You bear the risk if you live longer than assumed or costs rise faster | The paying party bears the risk |
| Full control over the money | Fixed, and cannot usually be converted to a lump sum later |
| Best suited to capital needs such as housing and adaptations | Best suited to recurring needs such as lifelong care and case management |
In practice the two are frequently combined: a lump sum for accommodation and equipment, and periodical payments for ongoing care.
Under the Damages Act 1996, where damages are for future financial loss the court may order that they take the form of periodical payments, and is required to consider whether to do so, whether or not the parties agree. For other heads of damages, both parties must consent. The court can only make such an order if it is satisfied that continuity of payment is reasonably secure.
The discount rate, and why it matters
Where future losses are paid as a lump sum, the figure is adjusted for the fact that the money can be invested before it is spent. That adjustment is the personal injury discount rate, set by the Lord Chancellor under the Civil Liability Act 2018.
In England and Wales the rate has been +0.5% since 11 January 2025, having previously been -0.25% since 2019. A higher rate assumes a better investment return and so reduces the lump sum awarded for future losses. On a claim involving decades of care, a change in the rate moves the final figure substantially, which is why the date your claim is valued can affect what it is worth.
Who can make a serious injury claim?
Anyone injured due to another party’s negligence within the last three years, including employees injured in a workplace accident, pedestrians, road users, and patients. Family members can act on behalf of those who lack mental capacity
You may be eligible if
- The injury was caused by someone else’s negligence or breach of duty
- The accident occurred within the last three years (or from date of knowledge)
- You suffered a physical or psychological injury with lasting consequences
- You are a UK resident or were injured in England or Wales
| Scenario | Eligible to Claim? | Who Pays | Notes |
|---|---|---|---|
| Injured in a road accident | ✓ Yes | At-fault driver's insurer | Strongest claim category |
| Serious injury at work | ✓ Yes | Employer's liability insurer | EL insurance compulsory by law |
| Medical negligence | ✓ Yes | NHS / private provider | Specialist evidence required |
| Partly at fault yourself | Likely | Defendant insurer (reduced) | Contributory negligence applies |
| Lacking mental capacity | Via litigation friend | Defendant insurer | Family member can act on your behalf |
| Over 3 years since accident | Usually not | — | Speak to a solicitor, exceptions exist |
Do you have a valid serious injury claim?
Answer four quick questions to receive clear guidance based on your circumstances.
Common mistakes in serious injury claims
The five most damaging errors: accepting an early settlement without full medical evidence, gaps in medical treatment records, posting on social media, discarding financial receipts, and speaking to the defendant’s insurer without legal advice.
Even strong serious injury claims can be weakened by missteps in the first few weeks. Watch out for these recurring issues we see on intake.
- Accepting an early settlement: initial offers are almost always well below the true long-term value of a serious injury claim
- Settling before the medical picture is clear: brain and spinal injuries can evolve; full prognosis evidence is needed before any settlement
- Gaps in medical follow-up: missing appointments or delays in treatment create gaps in records insurers use to argue you recovered faster
- Posting on social media: photos or updates showing physical activity can be used to challenge the extent of injury
- Discarding receipts and payslips: special damages require documentary proof of every financial loss.
How long does a serious injury claim take?
Most serious injury claims settle within 12 to 36 months. Brain and spinal injury cases can take longer due to the complex medical and financial evidence required before a fair settlement can be reached.
Serious injury cases take longer than standard personal injury claims for good reason. The medical picture needs time to become clear, prognosis reports and care assessments take time to commission, and financial modelling for lifetime care costs requires specialist expert input. Rushing that process typically means accepting a settlement that does not reflect real long-term needs.
If your claim was valued, or settled, using an earlier edition of the guidelines, it is worth taking advice on whether the settlement reflected current judicial standards. Updated guidelines matter most in brain and spinal injury cases where the general damages bracket shift is significant.
Time limits for serious injury claims
Three years from the date of the accident, or from your date of knowledge. Serious injury claims carry more exceptions than any other category, because brain injury frequently affects mental capacity, and where a claimant lacks capacity the limitation period is suspended entirely rather than merely extended.
The three-year rule under section 11 of the Limitation Act 1980 is the starting point, but it is rarely the whole answer in a serious injury case. Four situations change it, and three of them arise regularly in catastrophic injury work.
| Situation | Time limit | Runs from |
|---|---|---|
| Standard adult claim | 3 years | Date of the accident |
| Injury or cause discovered later | 3 years | Date of knowledge, which may be far later |
| Claimant lacks mental capacity | Suspended entirely | Never starts while incapacity continues |
| Claimant is under 18 | 3 years from their 18th birthday | Deadline is their 21st birthday |
| Fatal injury | 3 years | Date of death, or the dependant's date of knowledge |
| Court discretion | No fixed limit | Section 33 allows a late claim where equitable |
What if the injured person cannot manage their own affairs?
The limitation period is suspended for as long as the incapacity continues. If capacity is never regained, the clock never starts, and a litigation friend can bring the claim at any time. If capacity is regained, three years runs from that date rather than from the injury.
This matters enormously in brain injury cases. A family told that “the three years have run out” may well have been told something incorrect, because mental capacity is assessed under the Mental Capacity Act 2005 and the suspension under section 28 of the Limitation Act 1980 is absolute while it applies.
A litigation friend, usually a family member, conducts the claim in the injured person’s best interests. Where the compensation is substantial, the Court of Protection is generally involved in managing the award afterwards. Neither of those requirements shortens the time available to bring the claim.
What is the date of knowledge?
The date you first knew, or should reasonably have known, three things: that the injury was significant, that it was attributable to the act or omission complained of, and the identity of the defendant. All three are needed before the three-year clock starts running.
In most serious injury cases the accident and the knowledge coincide. Where they do not, usually in medical negligence or in injuries whose full extent emerges over months, the later date governs. Do not assume a claim is out of time without having the specific dates assessed.
Serious injury claims take 12 to 36 months to build properly, and the evidence that supports them degrades long before any legal deadline. CCTV is overwritten within weeks, witnesses become hard to trace, and the accident scene changes. A claim started in the first months will always be stronger than the same claim started in the final year.
Summary
A serious injury can affect your finances, independence, and family’s future for years. If someone else’s negligence caused what happened to you, the law provides a route to compensation that goes well beyond immediate costs, covering long-term care, rehabilitation, lost earnings, and quality of life. The most important steps are practical: seek medical attention, document everything from the start, and instruct a specialist solicitor before responding to any insurer. Three years sounds like a long time, but serious cases take time to build properly, and the earlier you start, the stronger your position.
Most serious injury claims settle without court proceedings. That said, thorough preparation for litigation is what keeps insurers honest. A fast early offer is almost always below what a fully evidenced claim is worth.
Key Takeaways
- Serious injury compensation covers the injury itself and all evidenced financial losses
- Brain injury general damages range from £15,580 to £493,000 under the JCG 18th Edition (April 2026)
- Special damages for care, lost earnings, and rehabilitation can raise total awards to seven figures in catastrophic cases
- Most claims must be started within three years of the injury or date of knowledge
- Contributory negligence reduces but does not extinguish a claim
- No Win No Fee means no upfront cost and no financial risk if the claim is unsuccessful
What You Should Do Next
If you or a family member has suffered a serious injury due to someone else’s negligence, the next steps are simple and free:
- Seek immediate medical attention: records created now become evidence later. Don’t delay even if injuries seem manageable at first
- Document everything: write down dates, times, what happened, any witnesses, and your symptoms. Memory fades; notes don’t
- Instruct a specialist solicitor: not a general personal injury firm. Serious cases need specialist expertise from the outset
- Don’t accept early offers: initial offers from insurers rarely reflect the full long-term value of a serious injury claim.

Frequently Asked Questions
How long does a serious injury claim take?
Most serious injury claims take between 12 and 36 months to resolve. Brain or spinal injury cases often take longer because the full medical picture needs time to develop, a fair settlement cannot be reached until a proper prognosis and care assessment are in place. Starting early with a specialist solicitor keeps the process moving and means interim payments can be requested if you have urgent financial needs during the claim.
