At the same time, access to experienced psychiatrists remains constrained. The Royal College of Psychiatrists’ 2025 workforce census recorded 5,193 consultant psychiatrist posts across responding NHS trusts in England. Around 14% were vacant, while the College calculated that 27% were either vacant or filled by non-substantive psychiatrists.
That workforce pressure does not prove increased medico-legal demand. It does, however, make experienced consultant psychiatric expertise a limited resource at a time when legal cases increasingly require more detailed assessment of psychological symptoms.
Psychological Injury Is No Longer a Secondary Issue.
Personal injury claims once tended to place physical injury at the centre of the medical evidence, with psychological symptoms treated as an additional consideration.
That distinction has become harder to maintain.
A claimant may recover physically yet continue to experience anxiety, depression, trauma symptoms, travel avoidance or pain-related distress. In another case, psychological factors may influence rehabilitation, employment or the persistence of physical symptoms.
A general medical report may identify those concerns, but identification is not the same as psychiatric diagnosis.
Where psychological symptoms become prolonged, severe or central to disability, a consultant psychiatrist can address questions that fall outside the expertise of an orthopaedic surgeon or GP.
The psychiatrist may need to determine whether the presentation supports a recognised psychiatric disorder, whether the accident caused or aggravated it and how long the resulting impairment is likely to continue.
That analysis can materially affect the direction and value of a claim.
Causation Has Become More Complex.
Psychiatric causation rarely reduces to a simple before-and-after comparison.
A claimant may have experienced anxiety or depression before an accident. Their medical records may show previous medication, bereavement, workplace stress, relationship difficulties or earlier trauma. Symptoms following an accident may therefore have several possible explanations.
The consultant psychiatrist needs to separate those strands.
Did the accident cause a new psychiatric condition? Did it aggravate an existing disorder? Would the claimant probably have experienced similar symptoms in any event? Has another event become the dominant cause?
These questions require more than recording the claimant’s current symptoms, they also require a detailed chronology, consideration of previous records and a reasoned explanation of competing causes.
That is one reason specialist psychiatric evidence becomes particularly important in higher-value or disputed cases. The more complicated the history, the less useful a simple statement that the claimant “developed anxiety following the accident” becomes.
Chronic Pain Creates Another Source of Instructions.
Persistent pain frequently brings physical and psychological evidence together.
A claimant may continue to report substantial pain after the expected period of tissue recovery. Reduced activity, disturbed sleep, fear of movement, low mood and loss of confidence may then influence the overall presentation.
None of this means the symptoms lack legitimacy.
It means the medico-legal analysis may need to move beyond the original physical injury.
A psychiatrist can help determine whether psychological symptoms represent a separate disorder, form part of the response to persistent pain or contribute materially to continuing disability.
This becomes particularly important when physical experts reach the limits of their own expertise.
An orthopaedic surgeon may properly explain that structural findings no longer account for the reported level of disability. That does not automatically answer why the symptoms continue.
Psychiatric evidence may provide another part of that explanation.
The Expert Must Still Be Necessary.
Increasing complexity does not mean every case requires a psychiatrist.
Under CPR Part 35, expert evidence in civil proceedings should remain limited to what the case requires. Experts also owe an overriding duty to assist the court on matters within their expertise rather than advocate for the party who instructs them.
That principle matters.
Minor travel nervousness after a road traffic accident does not automatically justify a consultant psychiatrist. Nor should ordinary distress become a psychiatric diagnosis simply because litigation exists.
The question should be whether specialist evidence will answer something that the existing medical evidence cannot answer adequately.
Where symptoms are mild, short-lived and improving, further psychiatric evidence may add little.
Where the claimant reports significant psychological disability, prolonged symptoms, a disputed diagnosis, complex pre-existing history or uncertain causation, the position changes.
The instruction needs a clinical purpose.
Experienced Experts Are a Limited Resource.
The supply side of the equation deserves attention too.
The Royal College of Psychiatrists reported in June 2026 that 1.8 million people were waiting for mental healthcare in England and that more than a quarter of consultant psychiatrist posts were unfilled or covered by temporary staff at the end of March 2025.
Clinical demand naturally takes priority within NHS services. Consultant psychiatrists who also undertake expert work must therefore balance medico-legal instructions against substantial clinical responsibilities.
That can create practical difficulties for instructing parties.
A solicitor does not simply need a psychiatrist. They need someone with the right subspecialty experience, sufficient recent clinical practice, appropriate expert-witness knowledge and enough capacity to review records and produce a reasoned report.
The Royal College of Psychiatrists’ guidance on expert evidence stresses the importance of psychiatrists defining their expertise properly and maintaining relevant professional competence.
A psychiatric qualification alone does not make every psychiatrist suitable for every psychiatric question.
Better Instructions Matter More as Demand Increases.
Greater demand also places responsibility on those instructing experts.
Poor letters of instruction waste specialist time.
A psychiatrist should not receive thousands of pages of records with vague questions asking for “comments on psychological injury.” The instruction should identify the real dispute.
Is diagnosis contested? Does the case require an opinion on causation? Is the claimant’s ability to work the main issue? Does the solicitor need a prognosis or an opinion about future treatment?
Clear questions help the expert focus on the matters that require psychiatric expertise.
They also reduce the risk of unnecessary supplementary reports and clarification questions later.
The Demand Reflects More Complex Claims.
The growing role of consultant psychiatrist experts should not be interpreted as evidence that every personal injury claim has become psychiatric.
It reflects something more practical.
Medico-legal cases increasingly require experts to distinguish between physical injury, psychological response, pre-existing vulnerability, chronic symptoms and functional disability.
Those distinctions can become difficult when symptoms persist and several factors interact.
A consultant psychiatrist can bring specialist clinical judgement to that problem, but only when the instruction genuinely requires it.
Demand for that expertise is therefore likely to remain strong.
The challenge is not simply finding more psychiatrists willing to write reports.
It is ensuring that specialist psychiatric evidence is requested at the right point, for the right cases and from experts whose experience matches the question they have been asked to answer.
