Hi-Vis Workwear Shirts — Professional Visibility for Every Shift

Are your hi-vis workwear shirts EN ISO 20471 certified?

Yes. Every hi-vis workwear shirt in this collection is certified to EN ISO 20471 — the recognised UK standard for high-visibility safety clothing. Each product listing states the specific class so you can confirm it meets your site's PPE requirements before ordering.

What is the difference between a hi-vis shirt and a hi-vis polo shirt?

A hi-vis workwear shirt is a crew-neck t-shirt style — no collar, no buttons. A hi-vis polo shirt has a collar and a short button placket. Both are EN ISO 20471 certified and carry reflective tape. The polo suits client-facing and supervisory roles where a smarter appearance matters. The t-shirt suits active physical roles where unrestricted movement and maximum breathability come first.

Can I wear a hi-vis shirt without a jacket or hoodie?

Yes, in warm weather where your site rules permit it. A certified hi-vis workwear shirt worn alone typically achieves EN ISO 20471 Class 2 — sufficient for most UK construction, warehouse and logistics environments. If your site requires Class 3, pair the shirt with certified hi-vis trousers. Always check your site induction paperwork for the specific class requirement.

Which colour do I need — yellow or orange?

Yellow is standard for most UK construction sites, warehousing, facilities management and general outdoor work. Orange is commonly required on roadside, traffic management and rail-adjacent sites — it contrasts better against grey tarmac and road markings. If your site or contract specifies a colour, that takes priority over personal preference. Both colours in our range carry retroreflective tape positioned to meet EN ISO 20471 requirements.

How do I wash a hi-vis workwear shirt to keep it compliant?

Machine wash at 40°C on a normal cycle. Do not use fabric softener — it coats the fluorescent fibres and reduces visibility performance over time. Do not tumble dry. Line dry away from direct sunlight, which degrades fluorescent dyes faster. Replace the garment once the fabric becomes visibly faded or the reflective tape starts to peel — a faded hi-vis shirt no longer meets EN ISO 20471 regardless of its age. Full guidance in the hi-vis washing guide.

Are hi-vis workwear shirts suitable for summer construction work?

Yes — this is exactly what they are designed for. Our hi-vis workwear shirts are short sleeve polyester, moisture-wicking and lightweight, built for warm-weather site work from April through September. They maintain full EN ISO 20471 compliance so you can switch to a lighter layer in summer without losing site safety certification. Pair with our hi-vis shorts for a complete summer kit.

Do you supply hi-vis workwear shirts for teams and bulk orders?

Yes. There is no minimum order quantity — you can order a single shirt or a full team kit-out through the standard checkout. For larger orders where you need to confirm stock levels across sizes before committing, get in touch and we will advise on availability and lead times.

Do hi-vis workwear shirts count as PPE under UK law?

Yes, provided they are certified to EN ISO 20471. Certified hi-vis clothing falls under the Personal Protective Equipment at Work Regulations 1992 — employers who identify high-visibility clothing as a PPE requirement must supply certified garments and replace them when they no longer meet the standard. HSE PPE guidance sets out the full legal framework.
