EN ISO 20471 & Hi Vis Workwear Compliance Explained

EN ISO 20471 is the core standard governing hi vis workwear and high visibility clothing used in UK workplaces where workers are exposed to traffic, moving vehicles, plant or other site hazards. It sets the visibility requirements garments must meet to help improve wearer conspicuity in daylight, low light and artificial lighting conditions.

Hi Vis Classes Explained

  • Class 1 – The lowest visibility level, generally used in lower-risk environments.
  • Class 2 – A common level for construction, logistics and general workplace use where stronger visibility is required.
  • Class 3 – The highest level of visibility, typically required for higher-risk environments and faster traffic exposure.

These classes are based on the minimum amount of fluorescent background material and reflective tape used in the garment. Higher classes provide greater conspicuity and are often needed where risk levels are higher. For a full breakdown, read our Hi Vis Classes Explained guide.

When Hi Vis Clothing Is Required

Employers must assess the level of risk before choosing the right hi vis garments. This includes considering traffic speed, lighting conditions, proximity to moving vehicles and the general working environment. In many situations, high visibility clothing is a necessary part of safe sitewear. Learn more in our guide to when hi vis clothing is required at work.

Colour Choice & Visibility

EN ISO 20471 applies to both yellow and orange high visibility garments, but the best colour for the job often depends on industry, site rules and environment. Rail and roadside applications may require more specific choices than general construction or warehouse work. See our Orange vs Yellow Hi Vis guide for more detail.

Employer Responsibilities

Employers are responsible for providing appropriate hi vis clothing based on workplace risk assessments. This includes selecting the right class of garment, checking it remains suitable for the task and replacing garments when fading, wear or damage affects compliance and visibility performance.

Branding & Compliance

Hi vis garments can be branded with logos and identifiers, provided the application does not reduce the minimum required fluorescent or reflective surface area. This is especially important for businesses ordering branded uniforms and site clothing for teams.

For branding support, read our guide to ordering branded workwear and our logo placement guide.

Hi Vis & Wider PPE Requirements

Hi vis garments are often worn alongside other essential site PPE such as safety helmets, safety footwear and other PPE to support full workplace protection across construction, rail and industrial environments.

All hi vis garments are supplied with manufacturer certification where applicable. Declarations of Conformity are available on request.
