What DSE means in law, who counts as a user, the five employer duties, the eye test entitlement, and why there is no annual assessment requirement.
The short answer
DSE stands for display screen equipment. The Health and Safety (Display Screen Equipment) Regulations 1992, amended in 2002, require employers to assess workstations, plan work to include breaks, provide eye tests on request, and give users information and training. The duties apply to users, wherever they work — including at home.
What Counts as Display Screen Equipment?
Any alphanumeric or graphic display screen, whatever the display process. HSE’s own description is “PCs, laptops, tablets and smartphones” — the definition is about the screen rather than the device category, which is why 1992 legislation still covers hardware nobody had imagined when it was written.
Two things sit outside it: DSE mainly intended for operation by the public, and portable systems not in prolonged use.
The workstation is wider than the screen. It includes the display, keyboard, mouse, software, chair, desk, any document holder or footrest, and the immediate working environment around it. When the Regulations talk about assessing a workstation, all of that is in scope.
Who Is a DSE User?
“User” is a defined legal term, and the duties attach to it. A user is an employee who habitually uses display screen equipment as a significant part of their normal work. Since the 2002 amendment, self-employed people doing equivalent work are covered as “operators”.
There is no bright line, but the practical indicators are:
- Use for continuous spells of an hour or more at a time
- Use more or less daily
- Fast transfer of information between user and screen
- High attention and concentration demands
- Reliance on DSE with little choice about using it
Someone who checks email for ten minutes a day is not a user. A contact centre operator, a designer, an administrator or anyone whose job is largely done on a screen almost certainly is. Where it is genuinely borderline, most employers apply the duty rather than spend time arguing the point — it costs less than the argument.
HSE is explicit that the law applies across working patterns, not just to people at a desk in an office. Fixed workstations, mobile workers, home workers and hot-deskers are all covered — and where someone changes desks regularly, they should carry out a basic risk assessment each time rather than relying on one done elsewhere.
Home and hybrid workers are users too
The duty follows the user, not the building. A DSE user working from home is covered exactly as one in the office, and home setups are usually worse because nobody chose a kitchen table for ergonomics. This is now the most commonly missed DSE duty — an employer with an immaculate office assessment record often has nothing at all for the days people work from a sofa.
The Five Employer Duties
| Duty | In practice |
|---|---|
| Assess workstations | Analyse each user’s workstation and assess the risks, then reduce them to the lowest extent reasonably practicable. See DSE assessment. |
| Meet workstation standards | Equipment must meet minimum requirements — adjustable screen and chair, adequate space, separate keyboard, suitable lighting, no distracting glare or noise. |
| Plan breaks | Plan the work so users get breaks or changes of activity. This means a break from the screen, not necessarily from work. |
| Provide eye tests | On request, at the employer’s cost — plus basic frames and lenses where glasses are needed specifically for DSE work. |
| Inform and train | Users must know the risks, the controls, and how to adjust their own workstation. Retrain where the workstation changes substantially. See DSE training. |
Eye Tests: What You Actually Owe
This is the duty employers most often get wrong in both directions — some think they must fund glasses for everyone, others think they owe nothing.
You must
Provide an eye and eyesight test if a user — or someone about to become one — requests it. Pay for it. And where the test shows glasses are needed specifically for DSE work, pay for a basic pair of frames and lenses.
You don’t have to
Fund glasses needed for general use rather than screen work. Fund designer frames or upgrades beyond a basic pair — though you may contribute. Or provide tests to the self-employed, who are not entitled to them.
How you arrange it is up to you. Some employers let users book their own test and reclaim the cost; others use a single optician or a corporate voucher scheme. Either satisfies the duty — provided users actually know the entitlement exists, which is where it usually falls down.
Breaks and Review: Two Common Myths
There is no annual assessment requirement
The Regulations set no fixed review interval. Assessments must be reviewed when something changes — new equipment, a new desk, a move, a change of role, a shift between office and home, or a user reporting discomfort.
Many organisations also review periodically as internal policy, commonly every one to two years, which is sensible for catching drift nobody has reported. But “we do them annually” is a policy, not a legal requirement — and an annual tick-box that misses a desk move in March is worse than a trigger-based system.
There is no prescribed break length either
No specific duration or frequency appears in the Regulations. HSE’s position is that short frequent breaks are more effective than longer infrequent ones, and that breaks should be taken before the onset of fatigue rather than to recover from it. A change of task counts — filing, a meeting, a phone call away from the screen. The old assumption that other office tasks would provide natural screen breaks holds less well in roles that are now entirely screen-based.
The Health Effects
Prolonged screen work is associated with musculoskeletal disorders — neck, back, shoulder and arm pain, and upper limb disorders including repetitive strain injury. Eye strain, headaches and general fatigue are also common.
None of it is dramatic, which is exactly why it gets ignored. These conditions build over months and years at a badly set up desk, and nobody notices the workstation is wrong until it has already caused a problem. They are rarely indicative of serious ill health, but they can be genuinely debilitating and they affect life outside work as much as in it.
The encouraging part is that most DSE problems are solved by adjusting a chair, raising a screen or adding a separate keyboard. Compared with almost any other safety intervention, the cost of getting this right is trivial.
If the DSE Regulations Don’t Apply
Worth knowing, because “they’re not a user” is sometimes treated as the end of the matter. Where display screens are in use but the DSE Regulations do not apply — no defined user or operator, or exempt equipment — the workers are still protected by the Health and Safety at Work Act and by other general legislation.
PUWER and the Workplace (Health, Safety and Welfare) Regulations 1992 cover suitable lighting and the working environment, and the Management Regulations still require risk assessment, information and training. The duty changes shape rather than disappearing.
Getting the assessments done
HSE publishes a free workstation checklist that most organisations use as the basis of a self-assessment. It works — provided a trained assessor reviews what comes back and acts on it. See DSE assessment for how to run one, or DSE training courses for assessor training.
Frequently Asked Questions
What does DSE stand for?
Display screen equipment. It is the legal term used in the Health and Safety (Display Screen Equipment) Regulations 1992 for any alphanumeric or graphic display screen — monitors, laptops, tablets and smartphones used for work.
Do DSE assessments have to be done every year?
No. There is no annual requirement in the Regulations. The trigger for review is change — new equipment, a new desk or location, a change of role, a move between office and home, or a user reporting discomfort. An annual cycle is a common internal policy and a reasonable backstop, but it is not what the law asks for.
Does my employer have to pay for my glasses?
If you are a DSE user and request an eye test, your employer must provide and pay for one. If the test shows you need glasses specifically for screen work, they must pay for a basic pair of frames and lenses. They do not have to fund glasses you would need anyway for general use, or pay the difference on designer frames. Eye tests are not an entitlement for the self-employed.
How long should DSE breaks be?
The Regulations set no duration. HSE’s guidance is that short frequent breaks work better than occasional long ones, and that they should come before fatigue sets in rather than after. A change of activity counts — the break needs to be from the screen, not necessarily from work.
Do the Regulations cover working from home?
Yes. The duties attach to the user rather than the premises, so a DSE user working at home is covered in the same way as one in an office. Most employers meet this with a self-assessment questionnaire reviewed by a trained assessor, which is reasonable — as long as someone competent actually reviews the responses and acts on them.
Are laptops and tablets covered?
Yes. The definition covers any alphanumeric or graphic display screen. Laptops are in fact the harder case, because the design forces a compromise between screen height and keyboard position — fine for short periods, poor for prolonged use. Where a laptop is someone’s main machine, a separate keyboard and mouse with the screen raised, or a docking station, is usually the answer.
