Can My Employer Ask About My Medical History in the UK?
If you’ve ever wondered whether your employer can ask about your medical history, you’re not alone. This question often arises during job applications, probation periods, or when health issues affect your work. In the UK, the answer is shaped by a mixture of employment rights, health and safety regulations, and equality laws. This post unpacks exactly what your employer can and cannot ask about your health, with a focus on stress as a workplace hazard, relevant Health and Safety Executive (HSE) duties, and the Equality Act’s disability definition.
Is There a General Obligation to Disclose Your Medical History?
Short answer: There is no general obligation for you to disclose your full medical history to your employer.
Under UK employment law and data protection rules (including the UK GDPR and the Data Protection Act 2018), your medical information is considered sensitive personal data. Employers must handle it with extra care and cannot Additional info demand medical details unless there is a clear, lawful reason.
During job applications, employers may only ask health-related questions:
- To assess your ability to perform specific tasks related to the role (for example, if the job involves manual handling, operating machinery, or lone working).
- To make adjustments as part of their legal duty under the Equality Act 2010 if you declare a disability or health condition that affects your work.
- When there is a clear occupational health reason, such as a health and safety risk or statutory health surveillance.
This means employers cannot insist on a blanket history of illnesses, previous conditions, or medications unless directly relevant.
What Are the Health and Safety Duties Around Stress?
Stress is increasingly recognised as a serious health and safety hazard in workplaces. However, unfortunately, it’s often misunderstood or dismissed as “just part of the job” or a “personal resilience issue.” The HSE (Health and Safety Executive) takes stress at work seriously and has clear guidelines around it.
HSE Stress Risk Assessments
The HSE requires employers to carry out stress risk assessments https://dlf-ne.org/how-do-i-talk-to-my-employer-before-a-drug-test-about-prescriptions/ as part of their general duty to ensure the health, safety, and welfare of employees under the Health and Safety at Work Act 1974. Stress is an identified workplace hazard under the HSE Management Standards.

Employers are expected to:
- Identify sources of work-related stress.
- Assess the risk and impact on employee wellbeing.
- Have clear plans to reduce or remove those risks.
- Monitor and review the effectiveness of these measures.
Crucially, the HSE Management Standards provide a benchmark that defines six key areas of work design that can contribute to stress:
- Demands (workload, work patterns, and the work environment)
- Control (how much say employees have in the way they do their work)
- Support (encouragement, sponsorship, and resources provided by the organisation, line management and colleagues)
- Relationships (promoting positive working to avoid conflict and dealing with unacceptable behaviour)
- Role (whether people understand their role within the organisation and whether the organisation ensures that they do not have conflicting roles)
- Change (how organisational change is managed and communicated)
What This Means For Medical Disclosure
If stress or mental health concerns are involved, your employer cannot just ask about your medical history or conditions without a workplace context. They must approach stress as a risk to be assessed through job design, support systems, and policy. If an employee discloses a stress-related condition or mental health disability, an employer may then ask relevant occupational health questions to consider reasonable adjustments under the Equality Act.
Occupational Health Questions: When Are They Appropriate?
Occupational health is a medical speciality focused on the relationship between work and health. Occupational health professionals sometimes carry out confidential assessments, but only with your consent and for a clear employment purpose.
Employers may ask occupational health questions:
- After you disclose a health condition affecting your work capability.
- If it is clear the role requires you to meet certain health standards (for example, commercial driving licences have medical fitness requirements according to the Road Traffic Act 1988).
- Where risk assessments suggest a health-related risk that needs investigation or management.
- When statutory health surveillance is required (such as monitoring for exposure to hazardous substances).
These questions are specifically focused on the individual’s ability to carry out job tasks safely and effectively and what adjustments might be needed. They are not attempts to collect a full medical history.
Equality Act: Disability and Medical Disclosure
The Equality Act 2010 protects employees from discrimination on the grounds of certain protected characteristics, including disability.

What counts as a disability? The Act defines a disability as “a physical or mental impairment which has a substantial and long-term adverse effect on a person’s ability to carry out normal day-to-day activities.”
If you declare a disability, your employer has a duty to make reasonable adjustments to remove any workplace barriers. This might involve changes to your role, hours, working environment, or providing equipment or support.
Given this, an employer can ask about your medical history only in relation to how your condition impacts your work and what adjustments might be needed. They cannot demand unrelated or irrelevant medical details.
