DSE Assessment: A Complete Guide for UK Employers and Remote Workers

Display Screen Equipment (DSE) regulations have been in force in the UK since 1992, yet DSE assessments remain one of the most overlooked employer duties — particularly since the shift to widespread remote and hybrid working. With musculoskeletal disorders now the leading cause of work-related ill health, getting DSE right matters both legally and practically.

What Are DSE Regulations?

The Health and Safety (Display Screen Equipment) Regulations 1992 (amended in 2002) apply to all workplaces where workers use display screen equipment — computers, laptops, tablets, and smartphones — as a significant part of their normal work.

The Regulations require employers to:

• Analyse workstations and assess and reduce risks
• Ensure workstations meet minimum requirements
• Plan work to provide breaks or changes of activity
• Arrange eye and eyesight tests on request
• Provide training and information

The Regulations were updated in 2002 to explicitly include portable devices such as laptops, though the physical requirements for portable equipment are inherently more limited.

Who Is a DSE "User"?

Not everyone who occasionally uses a computer is a DSE user for the purposes of the Regulations. The definition of a user (for employees) or operator (for the self-employed) is someone who habitually uses DSE as a significant part of their normal work.

The HSE guidance suggests that if a worker uses DSE for more or less continuous spells of one hour or more at a time, and uses it more or less daily, they are likely to be a DSE user.

This means:

• Office workers who spend most of their day on a computer: yes
• Receptionists who use a computer intermittently: yes, in most cases
• Warehouse workers who occasionally check a tablet: probably not
• Managers who use a laptop mainly in meetings: borderline — assess individually

When in doubt, include the worker in your DSE programme. The cost of an assessment is low relative to the cost of a musculoskeletal injury claim.

Conducting a DSE Assessment

A DSE assessment can be carried out by a trained assessor or, in lower-risk environments, via a structured self-assessment form completed by the worker. The self-assessment approach is widely used and HSE-approved — provided the form is comprehensive and the results are reviewed by someone competent to identify issues.

The assessment should cover:

Screen. Is the top of the screen at or just below eye level? Is there glare or reflection from windows or overhead lighting? Is the image stable and sharp?

Keyboard and mouse. Is there space in front of the keyboard for the wrists to rest? Is the mouse positioned close to the keyboard? Are wrists kept straight during use?

Chair. Is the chair height adjustable? Does the backrest support the lower back? Are feet flat on the floor or on a footrest? Can the armrests be adjusted or removed?

Desk and work surface. Is there adequate space to arrange equipment and documents without awkward reaching? Is the monitor at an appropriate distance (typically 50–70 cm from the eyes)?

Environment. Is lighting adequate without causing glare on the screen? Is the temperature comfortable? Is there excessive noise that causes distraction or tension?

Work patterns and posture habits. Does the worker take regular breaks or changes of activity? Are they aware of how to adjust their workstation?

Remote Workers and Home Working

The shift to hybrid and home working has significantly complicated DSE compliance. The 2002 amendment removed the previous exclusion for home workers — employers now have the same DSE duties towards home workers as they do towards office-based employees.

In practice, this means:

• Remote workers must be included in the DSE assessment programme
• A self-assessment questionnaire completed from home is the standard approach
• Where the assessment identifies risks, the employer must act on them — this may include providing equipment (monitor, chair, keyboard, mouse) for the home working environment
• Employers cannot simply assume that a worker's home setup is adequate

Hot-desking arrangements — whether in the office or at co-working spaces — add further complexity, as workstations are shared by multiple users with different needs. Each user's setup should be assessed and they should be trained to adjust the shared workstation appropriately.

Eye Tests

Employers must offer, and pay for, an eye and eyesight test for DSE users who request one. This must be carried out by a registered optometrist. If the test reveals that the worker needs spectacles specifically for DSE work (rather than for general use), the employer must also provide them — though only to a basic standard. The employer is not obliged to provide designer frames or pay for general-purpose corrective lenses.

Common Musculoskeletal Risks

DSE-related musculoskeletal disorders typically develop gradually and are often attributed by the worker to factors other than their workstation. The most common conditions include:

Upper limb disorders. Shoulder, neck, and arm pain caused by sustained awkward posture, particularly when the monitor is too high, too low, or too far to one side.

Wrist and forearm conditions. Including carpal tunnel syndrome and tendonitis, often linked to poor keyboard and mouse positioning or sustained grip.

Lower back pain. Caused by inadequate lumbar support, sitting too low relative to the desk, or sitting for prolonged periods without postural breaks.

Regular breaks and changes of activity — the Regulations require these — are one of the simplest and most effective controls. A short break every hour significantly reduces the risk of postural fatigue accumulating into a chronic condition.
