How personal injury compensation works in the UK

One of the first questions after an accident is, understandably, "how much is my claim worth?" It is also the hardest to answer in a sentence, because compensation is not a flat fee or a lottery payout. It is built, piece by piece, from the harm the injury has caused you — both the human harm and the financial harm — and it is grounded in medical evidence and established legal guidance rather than guesswork. This hub explains the two building blocks of every claim, how they are put together into a single figure, and what can push that figure down.

Before we go further, the most important point: this site is information, not legal advice. We are an independent educational resource, not a law firm or a claims management company. No website can value your individual claim. What we can do is explain the framework clearly so that, when you speak to a regulated solicitor, you understand what they are working out and why.

General damages — compensating the injury

General damages are awarded for the injury itself: the pain, suffering and loss of amenity (often shortened to "PSLA") that the accident has caused. This is the non-financial part of a claim — it puts a value on what you have actually been through and on the things you can no longer do or enjoy in the same way, rather than on money you have spent or lost.

Because pain cannot be measured with a receipt, the courts use a consistent reference point. The Judicial College Guidelines for the Assessment of General Damages in Personal Injury Cases — published by the Judicial College and updated periodically — set out illustrative brackets for different injuries, from minor soft-tissue strains to the most serious, life-changing harm. Solicitors and judges read these alongside comparable decided cases to find where a particular injury sits. The figure is then shaped by the detail in your independent medical report: how severe the injury was, how long recovery takes, whether there is lasting weakness, scarring or psychological effect, and how it has affected your work, hobbies and daily life.

It is worth stressing that any bracket figures you read about are illustrative ranges from the published Judicial College Guidelines, not a valuation of your claim. Two people with the "same" injury on paper can receive very different general damages once their medical evidence and individual circumstances are taken into account. Our guide on what compensation covers sets out the detailed breakdown of how these heads of loss work.

Special damages — your financial losses

Special damages are the financial, out-of-pocket side of a claim. They aim to put you back, as far as money can, in the position you would have been in if the accident had never happened. Unlike general damages, they are calculated from evidence rather than from guideline brackets, and on serious claims they are frequently the larger element. The main categories are:

• Loss of earnings — wages, bonuses, overtime or self-employed income lost while you were unable to work, plus any future loss of earnings where the injury affects your long-term earning capacity.
• Medical and rehabilitation costs — physiotherapy, counselling, prescriptions, private treatment where the NHS is not a realistic option, and ongoing rehabilitation.
• Care and assistance — the cost of help with washing, dressing, cooking or childcare, including gratuitous care provided free by family and friends, which can be valued and recovered.
• Travel and incidental costs — mileage or fares to medical and legal appointments, and other reasonable expenses caused by the injury.
• Aids, equipment and adaptations — wheelchairs, mobility aids or changes to your home or vehicle where the injury makes them necessary.

Keep receipts, payslips, invoices and a simple diary of expenses and help you receive — these are the proof that turns a loss into a recoverable figure.

Note: this table is deliberately qualitative. Any illustrative figures elsewhere — for example a bracket from the published Judicial College Guidelines — are illustrative only and are not a valuation of any individual claim.

How a claim is valued

Valuing a claim means combining the two parts above into a single, evidenced figure — and doing so carefully, because the amount has to last. The process usually runs like this:

1. Independent medical report. A medical expert examines you, confirms the diagnosis, and gives a prognosis — how long recovery will take and what, if anything, will be permanent. This drives the general-damages figure.
2. Proof of losses. Your solicitor gathers payslips, receipts, invoices and care records to build the special-damages schedule, including a reasonable projection of any future losses.
3. Negotiation. The total is put to the person at fault or their insurer, and the figure is negotiated. Most claims settle by agreement; only a small minority reach a court hearing.
4. Interim payments. In serious cases where liability is admitted, a solicitor can seek interim payments — money paid before the claim concludes — to help with immediate costs, treatment or lost income.

Throughout, your solicitor advises whether an offer is fair before you accept. The detail of each stage, and how long it tends to take, is set out in our step-by-step claim process guide. Getting the valuation right is one of the strongest reasons to use an experienced, regulated specialist — see choosing a solicitor for the questions to ask.

What can reduce compensation

A headline valuation is not always what reaches your bank account. Several factors can reduce the amount, and understanding them early avoids unpleasant surprises.

Contributory negligence. If your own actions contributed to the injury, a court can cut your award by the share you are found responsible for. A well-known example is not wearing a seatbelt in a car accident, which can reduce damages even though the other driver caused the crash. The reduction is applied as a percentage to the whole award.

Benefits recovery. If you received certain state benefits because of the accident, the Compensation Recovery Unit (CRU) may require the defendant to repay them, which can affect how much of the financial element you keep. Your solicitor accounts for this when advising on an offer.

Funding and success fees. Where a claim runs on a no-win-no-fee basis, a success fee (capped at 25% of certain damages in most injury claims) and any After-the-Event insurance premium are deducted from your compensation if you win. Our no-win-no-fee guide breaks down exactly how that works in plain English.

Time limits. None of this matters if a claim is started too late. Most injured adults have three years from the accident — but the exceptions are important, so check our time-limits guide before you assume.
