Modern organisations rely on digital screens across every operational function. From control rooms and corporate offices to home office setups and hot desking hubs, employees interact with display screens for extended periods. This shift in working patterns has transformed ergonomics from a simple compliance duty into a core operational priority for environmental health and safety (EHS) leaders.
A systematic display screen equipment (DSE) risk assessment is a core operational tool that safeguards employee health, reduces sickness absence, and builds workforce resilience. When managed properly, workstation assessments protect organisations against long term liability while driving daily performance and employee retention.
What is a DSE risk assessment?
A display screen equipment (DSE) risk assessment is a structured evaluation of an individual’s workstation, physical equipment, working environment, and task design. It applies to all workers who use a screen for more than an hour each day.
Defined under the Health and Safety (Display Screen Equipment) Regulations 1992 (as amended in 2002), the assessment ensures work setups meet statutory safety standards and minimise physical strain on workers. Devices that fall under DSE regulations include:
- Computers
- Laptops
- TV screens
- CCTV screens
- Interactive whiteboards
- Tablets
- Smartphones
- Equipment display screens
- Handheld devices
- Projection screens
As well as devices with a screen, a thorough assessment also examines the entire operational setup. This includes input devices, seating, desks, lighting, ambient conditions, and worker habits.

Who does a DSE risk assessment apply to?
Legal requirements under the Health and Safety (Display Screen Equipment) Regulations 1992 apply to any employee classified as a ‘DSE User’.
Under UK regulations, a DSE user is an employee who uses display screen equipment for more than an hour a day as a core part of their normal work. The regulations apply across all contract types, including full-time, part-time, fixed-term, and temporary staff.
Addressing modern workforce profiles
In today’s world, the working environment is no longer constrained to a single office building or workstation. Employees can now log in and perform their tasks from a variety of different settings all within the same week. Employers must consider and mitigate risks for every operational environment where screen work takes place:
- Hybrid and remote workers: Employers owe home-based staff the exact same legal duty of care as office-based personnel. Home workstations must undergo formal risk assessments and meet regulatory setup standards.
- Multi-screen and specialist users: Software engineers, financial traders, CAD designers, and control room operators face higher physical risks due to needing to use multiple monitors at once. These roles require specialised assessments to optimise head movement angles, focal distances, and monitor arrangements.
- Mobile and hot desking staff: Employees who rely on laptops, tablets, or smartphones while traveling or working at flexible hot desks require portable ergonomic accessories to maintain proper posture, such as laptop stands and separate keyboards or smart pens.
What hazards does a DSE assessment evaluate?
There are three key areas DSE risk assessors look at when evaluating a workstation:
1. Physical ergonomics and posture hazards
Physical hazards stem from poorly adjusted furniture or incorrect equipment positioning. Common examples include:
- Inadequate lumbar support: Seating that lacks adjustable lower back support causes static slumping, leading to spinal compression and lower back discomfort.
- Incorrect display height: Monitors positioned too high or low force continuous neck flexion or extension, leading to severe cervical spine strain.
- Unsupported forearms and wrists: Desks that lack sufficient depth prevent workers from resting their arms, causing repetitive wrist extension and shoulder strain during typing.
2. Visual and environmental hazards
Environmental factors directly influence worker comfort and visual performance. Key hazards include:
- Direct screen glare and reflections: High ambient light from unshaded windows or harsh overhead lighting creates reflection on screens, forcing employees into unnatural postures to view their work.
- Incorrect brightness and screen flicker: Poorly adjusted display contrast and older or damaged monitors cause rapid eye strain and chronic headaches.
- Constrained physical space and cable hazards: Restricted legroom under desks limits natural movement, while trailing power cables introduce immediate trip hazards.
3. Organisational and behavioural hazards
Work patterns often pose as much risk as physical hardware. Common behavioural hazards include
- Prolonged continuous screen time: Working for hours without stepping away from the desk leads to muscle fatigue and visual exhaustion.
- Monotonous and intense tasks: High-volume tasks without variation increases the risk of upper limb disorders and mental fatigue or ‘burn out’.
Why is a DSE risk assessment so important?
Proactive ergonomics management directly reduces work-related ill health. Prolonged use of poorly configured equipment causes work-related musculoskeletal disorders (WRMSDs) and visual strain, both of which impair employee wellbeing and organisational output.
Data published by the Health and Safety Executive (HSE GB) underscores the widespread operational impact of musculoskeletal ill health across UK workplaces:
- 511,000 workers suffered from a work-related musculoskeletal disorder in Great Britain, accounting for 27% of all work-related ill-health conditions.
- 173,000 new cases were reported within a single year, highlighting ongoing exposures in modern working environments.
- 7.1 million working days were lost due to WRMSDs, with affected individuals taking an average of 14 days of sick leave.
- 43% of cases involved the back (221,000 workers), while 41% affected the upper limbs or neck (211,000 workers).
Who is legally responsible for DSE risk assessments?
Full legal responsibility for carrying out workstation assessments rests with the employer or duty holder. Under the Health and Safety at Work etc. Act 1974 and the Health and Safety (Display Screen Equipment) Regulations 1992, employers must proactively protect workers from display screen hazards.
Employer statutory duties
To maintain DSE regulations compliance, employers must fulfil several key statutory requirements:
- Workstation assessments: Assess all workstations used by designated DSE users and implement necessary control measures.
- Eye tests and corrective eyewear: Provide free full eye and eyesight tests by a qualified optician upon request by a DSE worker. If the test shows that special corrective appliances (glasses) are required specifically for screen work, the employer must fund basic eyewear.
- Training and information: Provide clear instructions on ergonomic principles, correct chair and screen adjustments, and good posture habits.
- Work schedules and micro breaks: Design work routines to include periodic breaks or changes of activity to interrupt continuous screen time. While UK law does not mandate exact break durations, standard practice recommends short 5-to-10-minute rest breaks every hour.
Employee responsibilities
Employees also play an active role in workplace safety. Workers are expected to participate in required assessments, use provided equipment correctly, follow ergonomic guidance, and report physical discomfort or equipment defects promptly to management.
How to conduct a DSE risk assessment
Carrying out a thorough assessment involves a practical five-step workflow to identify hazards and maintain compliance across large enterprise workforces.
Step 1: Identify the hazards
Conduct a comprehensive workstation audit covering equipment, environment, and task layout. Key checks include:
- Screen height, tilt, distance, brightness, and freedom from reflection.
- Keyboard and mouse positioning to ensure neutral wrist alignment.
- Chair stability, height adjustment, and backrest support.
- Environmental factors, including lighting levels, space under the desk, and cable routing.
Step 2: Decide who is at risk and how
Identify specific user needs across the organisation. Consider individuals who may face higher risks, such as pregnant workers, staff with pre-existing back conditions, or employees working high-intensity multi-screen shifts.
Step 3: Evaluate risks and enforce controls
Apply practical corrective actions to reduce identified risks to the lowest reasonable level. This includes providing monitor arms, external input devices, footrests, or specialised task seating.
For large or distributed organisations, modern digital tools simplify assessment tracking and self-evaluations. Learn how enterprise management systems support compliance in our detailed review of what is the best ergonomics software on the market.
Step 4: Record data and action plans
Formalise assessment results and document corrective action items. Use recognised official templates to maintain standardised records, such as the HSE DSE Workstation Assessment Checklist (CK1) or the Ministry of Defence (MOD) Form 5013.
Step 5: Review and update
Establish scheduled review points and update records whenever working arrangements, software systems or equipment change.
When should you conduct a DSE risk assessment?
Risk assessments must be treated as dynamic, ongoing processes rather than one-off tasks. A display screen equipment risk assessment should be completed or updated whenever specific triggering events occur:
- Onboarding new staff: Complete an assessment whenever a new worker joins the organisation or sets up a workstation for the first time.
- Workstation modifications: Re-evaluate risks when new hardware, dual monitors, desk furniture, or core software interfaces are introduced.
- Location and pattern changes: Carry out assessments when an employee shifts to a hybrid routine, relocates their home desk, or moves to a new office site.
- Health and discomfort reports: Conduct an immediate review if a worker reports pain, eye strain, or discomfort, or when an individual returns to work after a musculoskeletal injury.
How often do you need to do a DSE risk assessment?
Assessments should follow a routine maintenance schedule backed by dynamic event reviews. Standard practice calls for regular reviews alongside instant updates whenever working conditions change:
- Annual or bi-annual scheduled audits: Conduct formal periodic reviews to verify that equipment remains in good working order and that user habits remain safe.
- Immediate dynamic reviews: Re-evaluate workstations immediately if an employee moves location, changes equipment, adopts new shift patterns, or reports physical discomfort.
Establishing a clear assessment schedule ensures continuous compliance while keeping employee wellbeing at the center of operational strategy.
Conclusion
DSE risk assessments create working environments where physical health, comfort, and performance support one another. Modern workstation safety relies on combining clear ergonomics policies, user education, and responsive assessment processes. Prioritising ergonomic wellbeing protects your employees and staff from preventable physical strain while helping maintain healthy, resilient, and engaged workforces over the long term.
