Hi-Vis Workwear: A Buyer’s Guide to Staying Safe and Compliant

Last reviewed: 17 August 2026 · Written and reviewed by the Xcel Print & Promotions team

hi-vis workwear saves lives. And that’s not sales talk. High-visibility clothing is a legal requirement in loads of UK workplaces for one reason: it slashes the risk of accidents where people are working near vehicles, machinery or in poor light.

The trouble is the classes, standards and garment types can tie you in knots, especially first time round. So here’s what you actually need to know to buy the right hi-vis for your team.

When is Hi-Vis Workwear Required?

Under UK health and safety law, employers have to provide suitable PPE where risks can’t be sorted another way. Hi-vis is usually needed wherever workers have to be seen, such as:

• Construction sites and roadworks
• Warehouses and distribution centres with moving vehicles
• Railway and trackside work
• Airport ground operations
• Highway maintenance and roadside recovery
• Refuse collection and street cleaning
• Any environment where workers are near moving traffic or machinery

And even where it isn’t legally required, plenty of businesses use it anyway for the extra safety margin. Delivery drivers, landscapers, event marshals, parking attendants, they all gain from being easier to spot.

Understanding EN ISO 20471

The European standard EN ISO 20471 (which the UK still recognises after Brexit) sorts hi-vis clothing into three classes, based on the minimum area of visible material:

Class 1, Lowest Visibility

Minimum 0.14m² of fluorescent background material and 0.10m² of retroreflective material. Class 1 garments are usually vests or waistcoats and give the least coverage. They suit low-risk settings with some separation from traffic. Think car park attendants, or warehouse staff in a controlled area.

Class 2, Medium Visibility

Minimum 0.50m² of fluorescent material and 0.13m² of retroreflective material. Class 2 is the most common standard for general workwear. It covers hi-vis polo shirts, t-shirts and lightweight jackets. Fine for most construction and warehouse environments.

Class 3, Highest Visibility

Minimum 0.80m² of fluorescent material and 0.20m² of retroreflective material. Class 3 gives maximum visibility and it’s what you need for the highest-risk work: on or near public roads, railways and airports. These are typically full jackets, coveralls, or a combination (say a Class 2 jacket with Class 1 trousers hitting Class 3 overall).

Fluorescent Colours: Yellow, Orange, or Red?

Three standard fluorescent colours turn up in hi-vis workwear:

• Fluorescent yellow, The usual pick. Best visibility in most daylight and against most backgrounds. If in doubt, go yellow.
• Fluorescent orange, Contrasts better against green backgrounds like foliage and grass. Popular with railway workers, landscapers and anyone out in the countryside.
• Fluorescent red, Less common over here. Sometimes used to mark out roles on site, supervisors in red, general workers in yellow, that sort of thing.

All three meet the standard, so your choice really comes down to the environment and any colour-coding your site already runs.

Types of Hi-Vis Garments

At Xceluk, we stock a full range of hi-vis workwear to cover every season and condition:

Hi-Vis Vests and Waistcoats

The simplest and cheapest option. Lightweight, easy on and off, available in all three classes. Ideal as an extra layer over other clothing. Often the go-to for visitors to a site or warehouse.

Hi-Vis Polo Shirts and T-Shirts

Comfortable in warm weather and indoors. Available in Class 2 and Class 3. A hi-vis polo with your embroidered logo is a smart, practical shout for the summer months.

Hi-Vis Sweatshirts and Fleeces

Mid-layer warmth with full hi-vis compliance. These come into their own in autumn and spring, when a jacket’s too much but a polo won’t cut it.

Hi-Vis Jackets and Coats

The workhorse of outdoor hi-vis. Everything from a lightweight softshell to a heavily insulated parka. Look for waterproof sealed seams, concealed hoods and plenty of pockets. Class 3 jackets are the standard for roadside and railway work.

Hi-Vis Trousers and Shorts

Often paired with a hi-vis top to push the overall class up. Combat-style hi-vis trousers with knee pad pockets are big in construction. Hi-vis shorts are there too, for warm-weather work where your risk assessment allows them.

Adding Your Branding to Hi-Vis Workwear

Yes, you can absolutely embroider and print on hi-vis. But there are a few rules to follow so the garment stays compliant:

• Don’t cover the reflective tape, The retroreflective strips have to stay clear. Logos go on the fluorescent background, not on or near the tape.
• Respect the minimum areas, Your branding mustn’t drop the fluorescent or retroreflective area below what the garment’s class requires.
• Common logo positions, Left chest (most popular), right chest, upper back between the reflective strips, and sleeve are all usually safe. We’ll point you to the best spot for your particular garment.

Our customisation and pricing page has the detail on branding hi-vis.

Caring for Hi-Vis Workwear

Hi-vis needs proper care to keep its protective properties intact:

• Wash to the garment label, usually 40°C or 60°C depending on the fabric.
• No bleach and no fabric softener. Both degrade the fluorescent finish over time.
• Replace garments once the fluorescent colour has clearly faded, or the reflective tape is damaged, peeling or dull.
• Check hi-vis regularly, especially for anyone in a high-risk job.
