Medical evidence is the foundation of almost every UK injury claim. The key document is an independent medico-legal report from a suitably qualified expert, who examines you, reviews your records and gives a diagnosis and prognosis. For most road-traffic injuries the report must be sourced through MedCo. The expert's view on how serious the injury is and how long it will last directly determines the value of the claim.
You can describe your pain as vividly as you like, but a UK injury claim stands or falls on the medical evidence. An independent expert's opinion is what proves the injury is genuine, links it to the accident, and shows how it has affected and will affect you. This guide explains how medical evidence works, what to expect from the examination, and why honesty matters so much.
One thing to be clear about from the outset: we are an independent information service, not a law firm and not a firm of solicitors. Nothing here is legal advice about your own situation. For that, speak to an SRA-regulated solicitor or use the official sources we signpost below.
Why medical evidence is central
Compensation for the injury (general damages) is valued by reference to the Judicial College Guidelines and comparable cases, and that placement depends entirely on the medical picture: the diagnosis, severity, treatment and prognosis. Your financial losses are also tied to the medical evidence — for example, lost earnings have to be justified by the medical view on your fitness for work. Without an independent report, an insurer has no reliable basis to accept the injury or its value, which is why it is almost always the first substantive step. See our evidence guide.
The independent medico-legal report
The central document is a medico-legal report prepared by an independent expert instructed for the claim (not your treating doctor). It sets out your history, the examination findings, a diagnosis, the likely cause, your treatment and a prognosis — how long symptoms are expected to last and whether any effects are permanent. The expert owes their duty to the court, not to whoever pays them, so the report is meant to be objective. In more complex injuries, several experts in different specialties may report.
MedCo for road-traffic claims
For most road-traffic soft-tissue (whiplash) claims, the medical report must be obtained through MedCo, the official portal that sources accredited experts and medical reporting organisations on a fixed-cost basis. This was introduced to standardise and improve the quality of whiplash evidence, and the report's prognosis decides which tariff band applies. If you are claiming through the OIC portal, it organises the MedCo report for you. See our whiplash guide for how the tariff links to the prognosis.
What to expect at the examination
The examination is usually short. The expert will take a history of the accident and your symptoms, ask about your daily life, work and recovery, and carry out a relevant physical or psychological assessment. Be accurate and consistent: describe your symptoms as they actually are, neither minimising nor exaggerating, and mention any pre-existing conditions honestly. The expert will often have your medical records, so inconsistencies show up. Bring a list of your symptoms, treatments and the impact on your life so you don't forget anything.
Why honesty protects your claim
⚠️ Exaggeration can sink the whole claim
It can be tempting to overstate symptoms, but if a court finds a claimant has been fundamentally dishonest, the entire claim — including the genuine part — can be dismissed and you may have to pay the other side's costs. Independent experts assess these cases regularly and compare what you say with your records. An honest, consistent account is both the right thing to do and the strongest claim you can present.
Frequently asked questions
Do I need a medical report for an injury claim?
In almost all cases, yes. An independent medico-legal report proves the injury is genuine, links it to the accident, and gives a prognosis that determines the value of the claim. For most road-traffic soft-tissue claims the report must be sourced through MedCo before the claim can be settled.
What is a medico-legal report?
It is a report prepared by an independent medical expert instructed for the claim, setting out your history, examination findings, diagnosis, the likely cause, treatment and prognosis. The expert owes a duty to the court rather than to whoever pays for the report, so it is intended to be objective.
What is MedCo?
MedCo is the official portal used to source accredited medical experts and reporting organisations for road-traffic soft-tissue (whiplash) claims, on a fixed-cost basis. It was introduced to standardise the quality of whiplash medical evidence, and the report's prognosis decides which tariff band applies.
What happens at a medico-legal examination?
The expert takes a history of the accident and your symptoms, asks about the impact on your daily life and work, and carries out a relevant physical or psychological assessment. It is usually short. Be accurate and consistent, and mention any pre-existing conditions honestly, as the expert often has your records.
Can exaggerating my symptoms harm my claim?
Yes, seriously. If a court finds a claimant has been fundamentally dishonest, the entire claim — including the genuine part — can be dismissed and you may have to pay the other side's costs. Experts compare your account with your records, so an honest, consistent account is the strongest approach.
