Employee health screening is one of those topics where a lot of employers aren’t quite sure where they stand legally. Is it something you have to do? Is it something you should do? And what happens if you don’t?
The short answer is that health screening is not a legal requirement for most UK employers. But the full picture is a bit more nuanced than that — and understanding the distinction between health screening and health surveillance could save you from either over-committing or inadvertently falling short of your legal obligations.

Is Health Screening a Legal Requirement?
For most UK employers, no. There’s no single piece of legislation that compels you to offer general health screening to your workforce as a routine benefit.
That said, health and safety law does place a broader duty of care on employers. Under the Health and Safety at Work Act 1974, employers are required to take reasonably practicable steps to protect the health, safety and welfare of their employees. Whether general health screening falls within that duty depends heavily on the nature of your workplace and the risks your employees face.
Health Screening vs. Health Surveillance: What’s the Difference?
This is where the confusion often starts, so let’s clear up the difference between health screening and health surveillance.
Health surveillance is a legal requirement in certain circumstances. According to the Health and Safety Executive (HSE), health surveillance is required where employees remain exposed to health risks even after control measures have been put in place. It’s specifically focused on detecting work-related ill health caused by those hazards.
Examples of work activities that typically trigger a health surveillance requirement include:
- Working with hazardous substances such as asbestos, lead or silica
- Exposure to biological agents, including blood-borne viruses and bacteria
- Regular exposure to noise or vibration
- Work involving ionising radiation
- Work in compressed air environments
If any of those apply to your workforce, health surveillance isn’t optional — it’s a legal obligation, and the HSE provides sector-specific guidance on how to carry it out.
Employee Health screening, by contrast, is broader. It covers general health aspects that may or may not be linked to work — blood pressure, cholesterol, blood glucose, body composition — and is a proactive measure rather than a regulatory one. For most employers, it’s not mandated, but it is increasingly recognised as good practice.
When Does Health Screening Become a Legal Requirement?
Health screening is not a legal requirement in most situations, but there are some specific exceptions where employers do have a legal obligation to provide certain types of health checks:
- Display screen equipment (DSE) users — employers must offer eye tests to employees who regularly use computers or laptops as a significant part of their role, under the Health and Safety (Display Screen Equipment) Regulations 1992
- Drivers and machinery operators — periodic medical checks may be required depending on the type of vehicle or equipment, the sector, and relevant licensing requirements
- Employees working overseas — where travel to certain destinations requires specific health clearance or vaccinations
- Employees injured or made ill by their work — employers have obligations around referral and support
Outside of those categories, health screening remains voluntary for employers. That doesn’t mean it’s unimportant, though. In fact, it’s quite the opposite.
Why Most Employers Choose to Offer It Anyway
Even where health screening isn’t a legal requirement, the business case for offering it is strong. The HSE’s 2024/25 statistics show that 964,000 workers in Great Britain experienced work-related stress, depression or anxiety — and that’s before accounting for cardiovascular conditions, which remain the single biggest cause of premature death in the UK.
The reality is that many employees have underlying health issues they’re unaware of. Our own screening data shows that 28% of employees who attend a workplace health screening are advised to book an appointment with their GP for follow-up — that’s more than one in four people who might otherwise have had no idea there was a problem.
For employers, that translates directly into reduced absenteeism, earlier intervention, and a workforce that’s better supported and more engaged. It also demonstrates a genuine duty of care that goes beyond the legal minimum, which is something that matters increasingly to employees when deciding where to work.
What About Data Protection and Consent?
If you do decide to offer health screening, there are some important compliance considerations around how you handle the results.
Employee health data is classified as special category data under the UK GDPR. That means participation must be voluntary, results must be kept confidential, and individual data must not be shared with line managers without explicit consent.
A good health screening provider will handle all of this for you — including providing anonymised aggregate reports so you can understand the health profile of your workforce without ever accessing individual results.
So, Is Health Screening a Legal Requirement or Not?
To summarise:
- For most employers, no — general health screening is not legally required
- If your employees are exposed to specific workplace hazards, health surveillance may be — and that’s a separate, legally defined obligation
- Some specific types of health checks are required in particular roles and sectors
- Beyond legal obligations, there’s a strong practical and ethical case for offering health screening as part of a wider employee wellbeing strategy
