Office Health and Safety Consultants:DSE, Fire Risk Assessments, and Compliance

Office environments are often assumed to be low risk. Health and safety inspectors disagree. Every employer operating an office, whether a five-person startup or a 5,000-seat corporate headquarters, has the same legal obligation to assess risks, appoint a competent person, and maintain documented compliance. The shift to hybrid working has expanded the legal scope significantly: every home-based screen user is in scope for DSE assessment, and home and hybrid working environments must be covered in the workplace risk assessment.

Arinite provides Qualified health and safety consultants and compliance software to office-based businesses across the UK and 50+ countries, including tech and SaaS companies, financial services, legal and consulting firms, marketing agencies, and corporate head offices.

The Health and Safety (Display Screen Equipment) Regulations 1992 require a documented DSE assessment for every habitual user of display screen equipment, defined broadly as anyone using a screen as a significant part of their normal work. In modern office environments that is effectively every employee.

Who Counts as a DSE User

What a Compliant DSE Assessment Includes

How Often DSE Assessments Must Be Reviewed

DSE assessments must be reviewed when the workstation, user, equipment, or working pattern changes significantly, including when an employee moves from full-time office working to hybrid working, or relocates their home working setup. Best practice for most office-based employers is annual review with interim review on change.

Common DSE Assessment Failures

The most common failure is a single self-declaration questionnaire issued at induction and never repeated. Self-declarations satisfy the assessment duty only if they identify and escalate issues to a competent assessor. They do not replace assessment. The second most common failure is treating home workers as out of scope.

Regulation 3 of the Management of Health and Safety at Work Regulations 1999 requires every employer to conduct a suitable and sufficient risk assessment covering all work activities. For office-based employers, the scope is broader than most realise.

For office-based businesses, the risk assessment is the foundation of every other compliance document: the policy, the safe systems of work, the training programme, and the inspection regime all flow from it. A risk assessment that has not been updated since the move to hybrid working is the single most common evidence of broader non-compliance.

The Regulatory Reform (Fire Safety) Order 2005 requires a documented fire risk assessment for every non-domestic premises in England and Wales, including every office, regardless of size. Equivalent duties apply in Scotland (Fire (Scotland) Act 2005) and Northern Ireland.

What a Compliant Office Fire Risk Assessment Covers

PAS 79 Methodology

Arinite's office fire risk assessments are delivered to PAS 79:2020 methodology, the British Standard recognised by fire and rescue authorities, insurers, and landlords as the practical benchmark for non-domestic fire risk assessment.

Multi-Tenant Buildings and Landlord Coordination

Office occupiers in multi-tenant buildings carry their own statutory duty separate from the building's responsible person. Common areas, fire alarm systems, and evacuation arrangements typically involve the landlord, but the occupier's own risk assessment for the demised premises is non-delegable. Arinite coordinates with landlords, managing agents, and other occupiers where required.

Regulation 7 of the Management of Health and Safety at Work Regulations 1999 requires every employer to appoint one or more competent persons to assist in undertaking the measures needed to comply with health and safety law. This duty applies to office-based employers in exactly the same way as it applies to construction or manufacturing employers.

What "Competent" Means in Practice

A competent person has sufficient training, experience, knowledge, and other qualities to enable them to assist the employer. HSE guidance is clear that the role cannot be filled by an HR generalist, a facilities manager, or a senior administrator unless they hold specific health and safety competence appropriate to the workplace risks.

Why Office-Based Businesses Routinely Get This Wrong

Many office-based businesses assume the competent person duty applies only to higher-risk sectors. It does not. The duty is universal. Arinite's competent person service provides an external Qualified competent person on a retainer basis, satisfying Regulation 7 without the cost of an internal hire and without the bottleneck of relying on a single individual.

Stress, burnout, harassment, and other psychosocial factors are statutory risk assessment categories under MHSWR Regulation 3, not optional wellbeing initiatives. The HSE Management Standards and ISO 45003:2021 set the practical framework. The Worker Protection Act 2023 adds a specific preventative duty on sexual harassment.

Mental health is typically the compliance area where office-based businesses have the biggest gap between what their HR function is doing (Employee Assistance Programme, mental health first aiders, wellbeing benefits) and what health and safety law actually requires (documented psychosocial risk assessment, line manager training, reasonable adjustments, documented Worker Protection Act reasonable steps).

The following is an illustrative example of how Arinite engagement typically runs for an office-based employer, drawn from common patterns across our office client base.

A 350-employee professional services business across three UK offices (London, Manchester, Bristol) and a hybrid working pattern approaches Arinite after an HR-led internal review flags the absence of a documented DSE programme for home and hybrid workers. The firm holds a basic health and safety policy and a fire risk assessment for the London office last reviewed three years ago. There is no documented psychosocial risk assessment, no Worker Protection Act 2023 documentation, and no competent person appointed.

The firm now operates an integrated office health and safety system across three sites with software-managed renewal cycles. The competent person retainer continues, satisfying MHSWR Regulation 7 for the year ahead.
