When people think about workplace injuries, they tend to picture physical harm — a broken bone, a back injury, a slip or fall. But psychological injuries caused by work can be just as serious, just as lasting, and in many cases just as compensatable under UK law. Conditions such as severe anxiety, clinical depression, and post-traumatic stress disorder (PTSD) caused or significantly worsened by an employer’s negligence are recognised personal injuries. And in 2026, with the Health and Safety Executive placing increasing weight on psychosocial risk alongside physical hazards, the legal framework for these claims has never been stronger.
Despite this, many workers who suffer genuine psychological harm at work never pursue a compensation claim — either because they do not realise they may be entitled to one, or because they are unsure whether their experience meets the legal threshold. This guide explains when a psychological injury at work can support a compensation claim in the UK, what you need to prove, how the process works, and what compensation you may be entitled to receive.
What Counts as a Psychological Injury at Work?
Not every form of stress or unhappiness at work amounts to a compensatable psychological injury. UK law draws a clear distinction between ordinary workplace pressure — which employees are generally expected to cope with — and a clinically recognised psychiatric condition caused by an employer’s failure to meet their duty of care.
To support a personal injury claim, your psychological condition must meet two requirements. First, it must be a recognised psychiatric illness that can be diagnosed according to accepted clinical criteria. Second, it must have been caused or significantly contributed to by your employer’s negligence or a failure to protect your mental health at work. Stress alone, without a diagnosed condition, is not sufficient.
Conditions that can support a claim
The types of psychiatric conditions most commonly seen in workplace psychological injury claims include clinical depression, generalised anxiety disorder, panic disorder, PTSD arising from a traumatic incident or sustained exposure to a hostile working environment, and adjustment disorder caused by sudden adverse changes in working circumstances such as unfair demotion or unjust disciplinary action. In each case, the condition must be formally diagnosed by a qualified medical professional — typically a GP, psychiatrist, or clinical psychologist.
What does not qualify
Feeling unhappy at work, experiencing normal levels of workplace pressure, or suffering temporary emotional distress that does not develop into a clinically recognised condition will not support a psychological injury claim. The law does not require workplaces to be free from all stress — only that employers take reasonable steps to prevent foreseeable psychiatric harm. The threshold is meaningful, but it is also one that many workers with genuine conditions do meet.
When Is Your Employer Legally Responsible?
Establishing that your employer is legally responsible for your psychological injury is the central challenge in these claims. Under UK law, employers owe their employees a duty of care that encompasses both physical and mental wellbeing. This duty arises from the Health and Safety at Work etc. Act 1974 and from the common law principles of negligence established through decades of case law.
For an employer to be found liable for a psychological injury, three conditions must generally be satisfied. The employer must have known, or ought reasonably to have known, that there was a foreseeable risk of psychiatric harm to you specifically. They must have failed to take reasonable steps to prevent that harm. And that failure must have caused or materially contributed to your condition.
Foreseeability: the key legal test
The concept of foreseeability is central to psychological injury claims. Courts do not expect employers to anticipate that every employee might experience mental health difficulties. However, where an employer is aware — or ought to be aware — that a particular employee is at risk, they are expected to act. Signs that put an employer on notice might include previous sickness absences linked to stress or anxiety, formal complaints about workload or bullying, a history of reported mental health difficulties, or a role that by its nature carries a high risk of psychological harm.
Common causes of employer liability
The most frequently cited grounds for employer liability in psychological injury claims include sustained bullying or harassment by managers or colleagues, excessive and unmanageable workloads that persist despite the employee raising concerns, failure to make reasonable adjustments for a known vulnerability, exposure to traumatic incidents without adequate support or debriefing, and a culture of harassment or hostility that the employer failed to address. From October 2026, employers are also directly liable under the Employment Rights Act 2025 for harassment of employees by third parties — such as customers or clients — where they failed to take all reasonable steps to prevent it. You can read more about how this change affects workers in our guide to the Employment Rights Act 2025 and workplace injury.
Building Your Psychological Injury Claim: The Evidence You Need
Psychological injury claims are more evidentially demanding than many physical injury cases, partly because the harm is not immediately visible and partly because courts require clear proof of both the psychiatric condition and the employer’s negligence. Understanding what evidence matters will help you build the strongest possible claim from the outset.
Medical evidence
A formal diagnosis from a qualified medical professional is the foundation of any psychological injury claim. This will typically take the form of a report from a GP, psychiatrist, or clinical psychologist setting out your diagnosis, its severity, its likely duration, and the extent to which it has affected your ability to work and carry out everyday activities. If you have not yet sought medical help, doing so promptly is the single most important step you can take. Early treatment records also demonstrate the timeline of your condition, which is relevant both to causation and to the valuation of your claim.
Workplace evidence
Evidence that your employer was aware of the risk to your mental health and failed to act is equally important. This can include written records of complaints you made about workload, bullying, or working conditions — particularly where these were made by email or in formal grievance procedures. Witness statements from colleagues who can speak to the working environment or specific incidents are valuable. HR records, occupational health referrals, performance review documents, and records of sickness absences attributed to stress or anxiety can all support your case. Where your employer conducted — or failed to conduct — a psychosocial risk assessment, this too may be relevant evidence.
Financial evidence
Special damages — the financial losses caused by your psychological injury — must be evidenced clearly and specifically. Keep records of all lost earnings, including payslips showing periods of reduced or no pay. Retain receipts for private counselling, therapy, medication, or other treatment costs. Keep a note of any travel expenses incurred for medical appointments. If your condition has affected your ability to return to your previous role or to work at all in the longer term, evidence of your future earning capacity will also be required.
How Much Compensation Can You Receive?
Compensation for a psychological injury at work is calculated in the same way as for physical injuries, comprising general damages for the pain, suffering, and loss of amenity caused by the condition, and special damages for the financial losses flowing from it.
General damages: the Judicial College Guidelines
General damages for psychiatric injuries are assessed by reference to the Judicial College Guidelines, which set out bracket ranges based on the severity and duration of the condition. For less severe psychiatric conditions from which a good recovery has been made or is expected, awards are typically in the range of several thousand pounds. For moderately severe conditions with significant ongoing symptoms, awards can reach into the tens of thousands. For the most severe and debilitating psychiatric conditions — those involving permanent disability and a very poor prognosis — general damages alone can exceed £100,000. The precise amount depends on the specific facts of your case and the expert medical evidence.
Special damages
Special damages in psychological injury claims can be substantial, particularly where the condition has resulted in a long period of absence from work or an inability to return to your previous level of employment. Lost earnings, both past and future, often represent the largest element of a psychological injury claim. These are calculated by reference to your actual earnings, any future promotional prospects, and the likely duration of your inability to work at your previous capacity.

Time Limits and the Claims Process
Psychological injury claims follow the same limitation rules as other personal injury claims. You have three years from the date on which you first knew, or ought reasonably to have known, that you had suffered a significant psychiatric injury caused by your employer’s negligence. In practice, this is often the date of your formal diagnosis rather than the date the working conditions began. Where there is uncertainty about when the limitation period starts, legal advice should be sought without delay.
Most psychological injury claims against employers are pursued through the civil courts rather than the Employment Tribunal, though in some cases — particularly where the psychological harm arose in the context of discrimination, harassment, or constructive dismissal — Tribunal proceedings may also be appropriate. The two routes are not mutually exclusive and can, in the right circumstances, be pursued alongside one another.
The majority of personal injury solicitors who handle workplace injury claims operate on a no win no fee basis, meaning you pay nothing upfront and nothing at all if your claim is unsuccessful. This makes specialist legal representation accessible regardless of your financial position. You can find out what to look for when choosing legal representation in our guide on how to choose the right injury attorney for your compensation claim.
Steps to Take If You Have Suffered Psychological Harm at Work
If you believe your employer’s negligence has caused or significantly contributed to a recognised psychiatric condition, acting promptly and methodically will protect your legal position and give your claim the best possible chance of success.
Seek medical help without delay
Visit your GP as soon as possible and be open and specific about how your work has affected your mental health. Ask for a referral to a specialist if your symptoms are severe. A contemporaneous medical record linking your condition to your working environment is among the most valuable pieces of evidence in a psychological injury claim. Do not minimise your symptoms or attribute them solely to personal factors if you believe your workplace has been a significant contributing cause.
Raise concerns in writing with your employer
If you have not already done so, raise your concerns formally with your employer in writing — whether through a grievance, a letter to HR, or an email to your line manager. This creates a dated record that your employer was put on notice about your situation. If your employer fails to respond appropriately, that failure is itself relevant to the question of whether they breached their duty of care.
Keep a detailed record
Keep a contemporaneous log of incidents, working conditions, and the impact of your condition on your daily life. Note dates, what was said or done, who was present, and how it affected you. This does not need to be a formal document — a private note on your phone or a simple diary will serve the same purpose. Over time, this record can corroborate medical evidence and demonstrate the timeline of your employer’s conduct and your deteriorating condition.
Take specialist legal advice early
Psychological injury claims involve complex questions of foreseeability, causation, and medical evidence that benefit significantly from early specialist input. A solicitor experienced in workplace injury and personal injury law can assess the strength of your claim, advise on the best route to compensation, and ensure that critical evidence is preserved before it is lost. The Health and Safety Executive’s guidance on work-related stress also sets out clearly what employers are required to do — and where those obligations are not being met, the law provides a route to justice.
