If you manage a team that regularly uses computers, laptops, or display screen equipment, you are legally required to carry out DSE risk assessments for those employees. This obligation stems from the Health and Safety (Display Screen Equipment) Regulations 1992, which were updated in 2002 to reflect modern working environments, including remote and hybrid setups.
A DSE risk assessment evaluates the workstation setup, the equipment being used, and the working habits of the individual to identify any risks to their health. Getting this process right from the start means you are less likely to face costly reviews, compliance issues, or employee health problems down the line.
How Long Is a DSE Risk Assessment Valid For?
There is no fixed legal expiry date for a DSE risk assessment, which surprises many employers when they first look into it. The Health and Safety Executive (HSE) does not specify that assessments must be renewed every one or two years, but the regulations do make clear that assessments must remain suitable and sufficient for the current situation.
In practical terms, this means a DSE assessment is valid for as long as the circumstances it covers remain unchanged. The moment there is a significant change to the workstation, the equipment, the role, or the employee’s health, the assessment should be revisited. Treating a DSE assessment as a one-time tick-box exercise is both a compliance risk and a missed opportunity to protect your staff.m.

How Often Should a DSE Risk Assessment Be Reviewed?
While the law does not mandate a specific review cycle, most occupational health professionals and HR advisors recommend reviewing DSE assessments at least once a year as good practice. Annual reviews help ensure that any gradual changes to an employee’s role or workstation have been properly captured and assessed.
Beyond the annual review, assessments should be revisited whenever a trigger event occurs. These triggers include a change in workstation location, the introduction of new equipment such as a new monitor or chair, a change in job duties that significantly alters screen time, or an employee reporting symptoms such as eye strain, back pain, or repetitive strain injury. Keeping a log of these trigger events makes the review process far easier to manage.
| Review Trigger | Recommended Action |
|---|---|
| Annual standard review | Re-assess all DSE users |
| New workstation or equipment | Immediate reassessment |
| Change in working location | New or updated assessment |
| Employee health complaint | Reassessment plus referral if needed |
| New employee starts | Assessment before or on commencement |
| Return from long-term absence | Review prior to return |
Can You Do Your Own DSE Assessment?
Many employers are surprised to learn that employees can, in many cases, carry out their own DSE self-assessment. The HSE permits this approach provided the self-assessment tool is well-designed, the employee receives appropriate guidance, and the results are reviewed by a competent person within the organisation.
Self-assessments work well for straightforward desk setups where the employee has a good understanding of ergonomic principles. However, for complex workstations, employees with existing musculoskeletal conditions, or setups that involve specialist equipment, it is advisable to bring in an external assessor or occupational health professional. The self-assessment route reduces burden on employers but should never be used as a way of cutting corners on compliance.
How Much Does a DSE Risk Assessment Cost?
The cost of a DSE risk assessment varies depending on whether you handle it internally or commission an external provider. Internal assessments using self-assessment software tools can cost as little as £5 to £20 per user annually, particularly when using platforms designed for bulk employee assessments.
External DSE assessments carried out by an occupational health specialist or ergonomist typically range from £75 to £250 per individual assessment, depending on the provider and level of detail required. For larger organisations, many providers offer volume discounts or annual contract pricing that brings the per-person cost down considerably. The table below gives a general overview of typical cost ranges in the UK market.
| Assessment Type | Typical Cost (UK) | Best Suited For |
|---|---|---|
| Employee self-assessment (software) | £5 to £20 per user | Low-risk, standard desk setups |
| HR or internal assessor | £0 to £30 per user | Organisations with trained staff |
| External occupational health assessor | £75 to £150 per user | Complex setups or health concerns |
| Specialist ergonomist assessment | £150 to £250 per user | Ongoing conditions or litigation risk |

Additionally, the GOV.UK page on workplace health and safety outlines broader employer obligations that sit alongside DSE regulations.
What Happens If a DSE Risk Assessment Is Not Carried Out?
Failing to carry out DSE risk assessments is a breach of the Health and Safety (Display Screen Equipment) Regulations 1992, and employers can face enforcement action from the HSE as a result. This can range from improvement notices to fines, depending on the severity of the non-compliance.
Beyond the legal consequences, neglecting DSE assessments exposes employees to preventable health risks, including musculoskeletal disorders, eye strain, and stress-related conditions. Employers who are found to have failed in their duty of care following an employee’s health complaint may also face civil claims, which can be significantly more costly than the assessment itself.
How Long Does a DSE Risk Assessment Last: What Every Employer Needs to Know
A DSE risk assessment does not come with a built-in expiry date, but that should never be interpreted as a reason to leave it untouched indefinitely. The legal standard is that assessments must remain suitable and sufficient, which means they need to reflect the current reality of each employee’s working setup at all times.
For most organisations, building an annual DSE review into the HR calendar is the most practical way to stay compliant without creating unnecessary administrative burden. Pairing that with a clear internal process for flagging trigger events, such as new equipment, location changes, or health complaints, ensures that nothing falls through the gaps between formal review cycles.
Ultimately, the question of how long a DSE risk assessment lasts is less about a fixed period and more about ongoing relevance. Employers who treat DSE compliance as a living process rather than a dated document are the ones best positioned to protect their staff and meet their legal obligations confidently.
How Long Does a DSE Risk Assessment Last: Frequently Asked Questions
No specific legal expiry date exists under UK law, but assessments must remain suitable and sufficient for the current situation. This means they should be reviewed whenever there is a relevant change in the employee’s workstation, role, or health.
Most occupational health professionals recommend reviewing DSE assessments at least annually, even if no obvious changes have occurred. This annual cycle helps catch gradual changes that might not trigger an immediate review.
Yes, new employees who will regularly use display screen equipment should have a DSE assessment completed at or before the start of their employment. This ensures any workstation issues are identified and resolved from day one.
Employees can complete a self-assessment provided the tool used is appropriate and the results are reviewed by a competent person. For a fuller explanation of what DSE covers and its history, the Wikipedia page on display screen equipment provides useful background.
Immediate reassessments are required when a workstation changes, new equipment is introduced, an employee’s role significantly changes, or an employee reports health symptoms linked to their workstation. Remote and hybrid workers should also be assessed whenever their home setup changes.
A self-assessment typically takes between 15 and 30 minutes, while an external assessor conducting a full workstation review may take between 45 minutes and 90 minutes. The time required depends on the complexity of the setup and any health concerns the employee has raised.
Yes, the DSE Regulations apply to employees who work from home on a regular basis, not just those in a traditional office environment. Employers are responsible for ensuring remote workstations are assessed in the same way as office-based setups.
Employers who fail to carry out DSE assessments can face enforcement action from the HSE, including improvement notices or fines. Employees who suffer health problems as a result of an unassessed workstation may also have grounds for a civil claim against their employer. The HSE’s DSE guidance outlines exactly what employers are required to do.
Not necessarily; many organisations use online self-assessment tools that employees complete remotely, with results reviewed by HR or an occupational health professional. In-person assessments are more appropriate when a health concern has been raised or the workstation is particularly complex.
The employer holds overall legal responsibility for ensuring DSE assessments are completed, but this duty is often delegated to HR managers, office managers, or trained internal assessors. For organisations without in-house expertise, external occupational health providers can take on this responsibility.
Yes, the DSE Regulations apply to any employee who uses display screen equipment as a significant part of their normal work, regardless of whether they are full-time or part-time. The key factor is regular, habitual use rather than occasional or incidental use.
A thorough DSE assessment should cover the chair and seating position, monitor height and distance, keyboard and mouse placement, lighting and glare, and the employee’s working patterns including break frequency. It should also capture any existing health conditions that may affect or be affected by the workstation setup.
Yes, a properly completed DSE assessment can serve as important evidence in demonstrating that an employer met their duty of care if an employee later makes a health-related claim. Conversely, the absence of a record can significantly weaken an employer’s position in any dispute.
There is no formal notice requirement; employees can request a reassessment at any time if they feel their workstation has changed or their health is being affected. Employers are expected to respond to such requests promptly and not treat them as an inconvenience.
