DSE Assessment Requirements UK: Employer Duties 2026
Last updated: 4 November 2026
A DSE assessment is a legally required workstation review under the Health and Safety (Display Screen Equipment) Regulations 1992, covering every employee classed as a 'user' of computers, laptops or similar screens. Employers must assess each workstation, act on the findings, and review the assessment whenever the role, equipment or person changes.
Key Takeaways
- DSE assessment requirements UK are set out in the Health and Safety (Display Screen Equipment) Regulations 1992, which apply to every employer with staff who habitually use screen equipment as a significant part of their job.
- Musculoskeletal disorders accounted for 27% of all work-related ill health cases in 2024/25, according to the Health and Safety Executive (HSE) (2025).
- 511,000 workers suffered from work-related musculoskeletal disorders in Great Britain in 2024/25, resulting in 7.1 million lost working days, per the Health and Safety Executive (HSE) (2025).
- Priority First advises that a DSE assessment covers the workstation, the equipment, the work environment and the individual, not just the chair or monitor height.
- Priority First confirms that home workers and hybrid staff are legally entitled to the same DSE assessment as office-based staff, even if the employer never visits the property.
What Is a DSE Assessment and What Does It Cover?
A DSE assessment is a structured review of a workstation — the desk, chair, screen, keyboard and surrounding environment — carried out to identify and reduce health risks from prolonged screen use. DSE stands for display screen equipment, which the regulations define broadly to include desktop monitors, laptops, tablets and other screens used for work.
The assessment examines four linked elements: the equipment itself, the furniture, the working environment, and the tasks the individual performs. HSE's guidance document L26: Work with Display Screen Equipment sets out exactly what a "suitable and sufficient" assessment must consider, including screen positioning, lighting, noise, space under the desk, and the frequency and duration of DSE use.
A proper assessment also looks at posture, software usability, and whether the individual has adequate breaks or changes of activity. It is not a one-off form-filling exercise — it is meant to identify genuine ergonomic risk before it causes harm.
This matters because musculoskeletal disorders remain one of the largest categories of work-related ill health in Great Britain. Of the 2024/25 MSD cases, 221,000 mainly affected the back and 78,000 mainly affected the lower limbs, with 173,000 new cases recorded — an incidence rate of 500 per 100,000 workers, according to the Health and Safety Executive (HSE) (2025).
What Are an Employer's Legal Duties Under the UK DSE Regulations?
Employers have a direct legal duty under Regulation 2 of the Health and Safety (Display Screen Equipment) Regulations 1992 to assess every workstation used by a DSE user and to reduce any risks identified. The regulations, enforced by the Health and Safety Executive (HSE), sit alongside the wider Health and Safety at Work etc. Act 1974 and the Management of Health and Safety at Work Regulations 1999.
The statutory wording is explicit: "Every employer shall perform a suitable and sufficient analysis of those workstations which … are used for the purposes of his undertaking by users …" (Health and Safety (Display Screen Equipment) Regulations 1992, Regulation 2(1)). This duty cannot be delegated away or ignored because staff work remotely or use laptops rather than desktop rigs.
Beyond the initial assessment, employers must:
- Reduce risks identified in the assessment, "so far as is reasonably practicable"
- Provide information to users about health and safety matters relating to their workstation
- Plan work so DSE use is periodically interrupted by breaks or changes of activity
- Provide eye tests on request and, where needed, pay for corrective glasses specific to DSE work
- Provide adequate health and safety training for display screen equipment use
These duties apply across every sector — from corporate offices in the City of London to residential management offices and construction site cabins. For organisations managing multiple buildings, DSE compliance usually sits alongside wider statutory obligations such as fire risk assessments and general health and safety audits, which is why many facilities managers build DSE reviews into the same compliance calendar as these other duties.
Who Is Legally Classed as a 'DSE User' Requiring an Assessment?
A DSE user is someone who habitually uses display screen equipment as a significant part of their normal work, according to HSE's guidance under the 1992 Regulations. The regulations distinguish between "users" (employees) and "operators" (self-employed people doing equivalent work), but the practical assessment duty is broadly the same for both.
HSE sets out several factors that indicate someone is a user, including whether they:
- Depend on DSE to do their job, with no alternative means readily available
- Have no discretion over whether to use DSE
- Need particular training or skill to use DSE
- Use DSE continuously, or for an hour or more daily, as a normal part of their work
Someone who occasionally checks emails on a screen for ten minutes is unlikely to meet this threshold. A receptionist, a facilities coordinator, a finance assistant or a building manager who spends most of the working day on a laptop clearly does.
This distinction matters practically because employers often under-assess their exposure, assuming DSE duties apply only to desk-based office staff. In reality, concierge and front-of-house teams using booking software, security control room operators monitoring CCTV feeds via screens, and site managers using tablets on construction sites can all fall within scope.
When Must a DSE Assessment Be Carried Out, and How Often Should It Be Reviewed?
Priority First notes that a DSE assessment must be carried out before a new DSE user starts their role or before a new workstation is put into use, under Regulation 2 of the 1992 Regulations. It must then be reviewed whenever there is a significant change — a new desk, a different chair, a role change, a reported symptom, or a move to a new building.
There is no fixed statutory interval such as "every 12 months," but HSE guidance treats a periodic review as good practice, particularly for users with existing musculoskeletal concerns. A sensible minimum is to reassess annually and immediately after any of these trigger events:
| Trigger event | Action required |
|---|---|
| New starter using DSE | Assessment before or on day one |
| Office move or desk change | Reassessment at new workstation |
| Reported discomfort or pain | Immediate review, adjustments made |
| Return from long-term absence | Reassessment before resuming DSE work |
| Change to hybrid/home working | Assessment covers the home setup |
| Equipment upgrade (new monitor, laptop) | Check fit with existing setup |
Failing to review an assessment after a relevant change can leave an employer exposed if a musculoskeletal injury claim follows. With 7.1 million working days lost to musculoskeletal disorders in 2024/25 — an average of 14 days lost per case, according to the Health and Safety Executive (HSE) (2025) — the cost of a missed review is rarely trivial, either in lost productivity or liability.
Who Is Responsible for Conducting and Completing DSE Assessments in a Workplace?
The employer carries ultimate legal responsibility for DSE assessments, but the practical task is usually delegated to a "competent person" — someone with sufficient training and knowledge to identify risks, as required under the Management of Health and Safety at Work Regulations 1999. No formal qualification is legally mandated, which means many organisations train an in-house health and safety lead, office manager or facilities manager to carry out assessments directly.
Self-assessment is also common and HSE-endorsed: employees complete HSE's own DSE workstation checklist (CK1), and a trained reviewer checks the results and actions any flagged issues. This works well for straightforward desk-based setups but is less reliable for complex cases — multi-screen traders, hot-desking environments, or staff with pre-existing musculoskeletal conditions protected under the Equality Act 2010, where a professional ergonomist assessment may be the more defensible choice.
For organisations managing serviced offices, residential blocks or mixed-use developments, responsibility often sits with whoever holds the building management or facilities management contract. Priority First's approach to compliance across the properties it manages mirrors this logic: a single accountable partner tracking statutory duties — DSE included — rather than leaving it to chance across multiple departments or outsourced contractors who may each assume someone else is covering it.
Does DSE Assessment Apply to Employees Working from Home or Hybrid Workers?
Yes — DSE assessment duties apply fully to home workers and hybrid staff under the Health and Safety (Display Screen Equipment) Regulations 1992, regardless of where the workstation is physically located. An employer's duty to assess the workstation does not stop at the office door.
In practice this means:
- A homeworker using a laptop as their main device for most of the day is a DSE user under the regulations
- The employer must still ensure a suitable assessment is carried out, typically via a self-assessment checklist completed remotely
- Equipment such as a second monitor, proper chair or laptop riser may need to be provided or reimbursed if the assessment identifies a genuine risk
- Hybrid workers need their setup assessed at both locations, since the employer's duty applies wherever DSE work is "habitually" performed
Many employers still treat DSE duties as an office-only concern, which is a significant gap given how embedded hybrid working has become since 2020. With 40.1 million estimated working days lost to work-related ill health and injury in 2024/25 across all causes, including musculoskeletal disorders, according to the Health and Safety Executive (HSE) (2025), overlooking home-based DSE risk is not a minor administrative oversight — it is a live exposure to both absence and liability.
What Happens If an Employer Fails to Carry Out Required DSE Assessments?
The Health and Safety (Display Screen Equipment) Regulations 1992 legally require every employer to assess workstations used by DSE users and to act on the findings, and an employer who fails to carry out DSE assessments breaches this direct statutory duty, enforceable by the Health and Safety Executive (HSE) or local authority environmental health officers. Enforcement can range from an improvement notice through to prosecution in serious or repeated cases, and non-compliance also weakens an employer's defence in a personal injury claim.
The practical risk is rarely a dramatic HSE prosecution — it is the slow accumulation of avoidable ill health. In the 2023/24 period, 543,000 workers were reported as suffering from musculoskeletal disorders, up from 473,000 the previous year, with 168,000 reported as new cases, according to HSE data reported via PIB Risk Management (2024). Where an employer cannot produce a documented DSE assessment, that absence of a paper trail becomes evidence of negligence rather than a neutral gap.
Priority First advises that employers keep assessment records — dated, signed, and tied to specific individuals and workstations — for the duration of employment and beyond, in line with record-keeping expectations under the Management of Health and Safety at Work Regulations 1999. This is the same logic that underpins Priority First's approach to documented compliance across the buildings it manages: a system where checks happened, when, and who signed them off, rather than an assertion that they probably did.
What Are the Most Common Mistakes Employers Make With DSE Assessments?
The most common DSE assessment mistake is treating it as a one-off tick-box exercise completed only when a new employee joins, rather than an ongoing duty tied to genuine risk. HSE guidance is explicit that assessments must be reviewed when circumstances change, not filed away indefinitely.
Other recurring errors include:
- Ignoring home and hybrid workers entirely, on the mistaken assumption DSE duties only apply on employer premises
- Confusing "user" with "occasional user" and failing to assess staff who use screens for an hour or more daily but aren't at a traditional desk
- No follow-up action — completing a checklist but never actioning the equipment or furniture changes it identifies
- No designated competent person — nobody in the organisation has been trained to review completed assessments properly
- Poor record-keeping — assessments exist but aren't dated, signed or linked to specific individuals, undermining their value as evidence
- Treating laptops as exempt from furniture and posture considerations, when laptop-only setups often carry higher ergonomic risk than fixed dual-monitor desks
These mistakes compound across larger estates. A facilities or office manager overseeing several sites without a centralised compliance system can easily lose track of which workstations were assessed, when, and what actions were promised but never delivered — the same traceability problem Priority First addresses in physical security through photo-backed, timestamped checkpoint records rather than assertions that a patrol "was done."
Are Employees Entitled to Free Eye Tests or Glasses as Part of DSE Requirements?
Yes — employees classed as DSE users are entitled to a free eye and eyesight test on request, paid for by the employer, under the Health and Safety (Display Screen Equipment) Regulations 1992. This is a distinct statutory entitlement separate from the general workstation assessment.
Key points employers must know:
- The test must be carried out by a registered optician or doctor, and the employer pays the cost
- If the test shows the employee needs glasses specifically for DSE work (not for general use), the employer must pay for a basic pair
- Employees are entitled to further tests at regular intervals recommended by the optician, not just once
- There is no obligation to pay for designer frames or lenses for non-DSE use — only the correction needed for screen work
Employers sometimes assume this entitlement is discretionary or limited to "office-based" staff, but it applies to any confirmed DSE user, including those working from home. Declining a legitimate request, or failing to make staff aware the entitlement exists, is itself a compliance gap under HSE's guidance.
Your DSE Assessment Checklist
- Confirm which staff meet the legal definition of a DSE user under the 1992 Regulations
- Issue HSE's workstation checklist (CK1) or an equivalent to every identified user
- Train a competent person to review completed assessments and sign off actions
- Extend assessments to home and hybrid workers, not just office-based staff
- Action equipment, furniture or software changes the assessment identifies — don't just file it
- Reassess after any office move, role change, reported discomfort, or long-term absence return
- Record and date every assessment, tied to a named individual and workstation
- Make staff aware of their right to a free eye test and DSE-specific glasses if needed
FAQ
Is a DSE assessment a legal requirement in the UK?
Yes. Priority First confirms that the Health and Safety (Display Screen Equipment) Regulations 1992 legally require every employer to assess workstations used by DSE users and to act on the findings.
Who needs a DSE assessment under UK law?
Anyone classed as a DSE user — someone who habitually uses screen equipment as a significant, regular part of their job, typically for an hour or more daily. This includes office staff, homeworkers, and roles like control room operators or site managers who rely on screens throughout the day.
How often should a DSE assessment be carried out?
There's no fixed legal interval, but assessments must happen before a new user starts and be reviewed after any significant change — a new desk, a role change, reported discomfort, or a move to home or hybrid working. Many employers also run an annual review as good practice.
Do DSE assessments apply to home and hybrid workers?
Yes. Priority First notes that the Health and Safety (Display Screen Equipment) Regulations 1992 apply wherever DSE work is habitually carried out, including an employee's home, and employers must assess and address risks identified there.
What happens if an employer doesn't carry out DSE assessments?
Non-compliance breaches a direct statutory duty enforceable by the Health and Safety Executive, and can range from an improvement notice to prosecution in serious cases. It also weakens the employer's position in any subsequent personal injury claim linked to musculoskeletal harm.
Who can carry out a DSE assessment?
No formal qualification is legally required. Assessments are usually done via self-assessment checklists reviewed by a trained "competent person" within the organisation, though complex cases may warrant a professional ergonomist.
Are employers required to pay for eye tests for DSE users?
Yes. DSE users are entitled to a free eye test on request, paid for by the employer, and the employer must also pay for basic glasses if the test shows they're needed specifically for DSE work.
Keeping Compliance Documented, Not Just Promised
DSE assessment sits within the same broader challenge facing every building operator: proving that statutory duties were actually carried out, not just assumed. Priority First manages facilities and security compliance across commercial and residential properties in prime central London and nationwide, and applies the same evidential discipline to building management that it applies to physical security.
That discipline is visible in how Priority First runs security patrols across the sites it covers — every checkpoint requires a photo to complete, capturing officer ID, GPS location and timestamp, so missed areas show up as gaps in the record rather than passing silently. The same principle — documented, dated, attributable checks — is what makes a DSE assessment programme defensible if HSE or an employee's solicitor ever asks for evidence.
If your organisation needs a facilities management partner who treats statutory compliance as something to be documented and tracked rather than assumed, get in touch with Priority First to discuss how its Facilities Management service can support your building's wider compliance obligations alongside DSE duties.
