Winter workwear works when it matches the role, fits over the other PPE and can be adjusted by the wearer. For most UK teams that means a three-layer system, a waterproof and windproof outer shell, hi-vis that carries its certification into the cold months, and a trial before any bulk order. This guide covers what employers must provide, what to specify for each sector, and how to order without ending up with jackets that do not fit.
TL;DR
- Employers must assess cold risks and provide suitable protection. HSE guidance sets usual workroom minimums of 16°C, or 13°C for strenuous work.
- Use three layers: a moisture-wicking base, an insulating mid-layer and a windproof, waterproof shell.
- Winter hi-vis must still meet the required standard, and thick jackets must not interfere with helmets or harnesses.
- Pilot garments with a small, varied group of staff before a bulk order, and keep a buffer of outer shells, gloves and socks.
- Specify by role. Site crews, hospitality staff, school staff and security teams need different garments.

What employers must provide in cold weather
There is no statutory minimum temperature for outdoor work in the UK. The duty is wider: employers assess the risk and put controls in place. For indoor rooms, the HSE managing temperature guidance says a reasonable temperature is usually at least 16°C, or 13°C where the work involves strenuous effort. Where heating and other controls are not enough, protective clothing and somewhere to warm up become part of the answer.
Outdoors, the weather can affect health immediately or over time if the risk is not managed. The HSE outdoor working page is the starting point for a written assessment covering gusts, wet, ice and exposure time. Clothing is one control among several. Rotating tasks, scheduled breaks and sheltered rest areas sit alongside it.
A practical consequence for buyers: winter clothing is not a perk or a branding exercise only. For site, grounds, logistics and similar roles it is part of the risk control, so it should be specified, documented and replaced when worn out.
The three-layer system
One heavy coat is the common mistake. It traps sweat during activity and leaves the wearer cold as soon as they stop. The approach recommended in Banner UK’s winter protective workwear guidance is three layers, each with a job:
- Base layer. Moisture-wicking, worn next to the skin to keep it dry. Cotton holds moisture, so synthetic or wool-blend fabrics are the usual specification.
- Mid-layer. Fleece or softshell to trap heat. This is the layer staff add or remove as the task changes.
- Outer shell. Windproof and waterproof, with taped seams for outdoor roles, to block wind and rain.
The benefit is control. Workers can strip a layer when lifting or climbing and add one when standing still, which prevents overheating and sweat build-up that can rapidly lead to cold stress.
Let staff adapt
Thermal comfort varies from person to person. The HSE thermal comfort guidance lists adding or removing clothing among the ways people adapt to their environment. For managers, the low-cost step is a uniform policy that allows layers: an approved fleece or hoodie option, a choice of base layers, and tolerance for extra items where safety is not affected.
Winter hi-vis clothing
Hi-vis is where winter buying most often goes wrong. A warm jacket is not automatically a compliant one. The HSE high visibility clothing factsheet explains that the Personal Protective Equipment at Work Regulations 1992 require several factors to be considered, starting with whether the clothing is suitable for the risk. Winter hi-vis should conform to EN ISO 20471, and Class 3 is the highest level of conspicuity. Check the class on the garment label, not just the product title.
Three checks before ordering winter hi-vis:
- Standard and class. The garment carries the EN ISO 20471 marking at the class your risk assessment requires.
- Compatibility. The jacket must not interfere with the correct fit of a harness or helmet. The HSE notes that damaged or ill-fitting PPE can invalidate protection.
- Condition. Dirty, faded or damaged hi-vis loses effect, so cleaning and replacement need a schedule.
On the product side, our hi-vis collection covers custom hi-vis uniform, and the hi-vis vests and waistcoats range suits layering over a warm mid-layer. The Berlin Hi-Vis Executive Vest is one option for supervisors who need visibility over smart clothing. For cold-weather trousers and tops, see the Women’s PW3 Hi-vis ¼-zip sweatshirt and Safety high-viz trousers.
Choosing by role
Generic bundles rarely suit a mixed workforce. The Banner UK guidance advises selecting by role-specific requirements, and the table below turns that into a starting specification.
| Role | Priority | Typical winter specification |
|---|---|---|
| Construction and maintenance | Durability, weather protection | Waterproof, windproof shell with reinforced stress points, hi-vis where required, insulated gloves, thermal socks |
| Surveyors, supervisors | Professional look, outdoor-indoor use | Softshell hybrid layers, hi-vis vest over the top |
| Hospitality (outdoor service, deliveries, car parks) | Appearance, warmth, mobility | Branded jackets or hoodies, fleece mid-layers, caps or beanies |
| Education and childcare | Outdoor duty, easy care | Branded fleeces, waterproof jackets for playground and trip duty |
| Security | Long static periods, recognisability | Insulated jackets, hi-vis where posted, thermal base layers |
Construction and maintenance
Outer garments in construction suffer higher wear rates and frequent loss. The most common complaints often come from small items: gloves and socks. Insulated, grip-enhanced gloves and thermal socks deserve a line in the specification, not an afterthought.
Headwear needs particular care. Safety professionals caution against wearing a hoodie under a safety helmet, because it can compromise the fit and security of the helmet. The alternative is purpose-designed thermal headgear and base layers that work with mandated site PPE. For the wider checklist, see our branded PPE guide.
Waterproofing is the other decision. Ratings differ, and a rating suited to a drizzly delivery round is not what a groundworks crew needs. The waterproof jacket ratings guide explains how to match rating to role.
Hospitality
Front-of-house staff may only be outside for minutes at a time, but doormen, valets, terrace staff and delivery teams are out for hours. Branded jackets and hoodies carry the identity of the business through the winter, and embroidery on a fleece survives repeated washing better than many printed finishes. Specify one smart outer layer that works for the whole team, and allow a plain base layer underneath.
Education
Nurseries and schools need staff to be outside for playground duty, trips and drop-off in all weather. Layers that wash easily and look consistent matter more than technical specification. Our education staff uniform buyer’s guide covers the points specific to schools and nurseries.
Security
Security staff on gate, car park or perimeter posts stand still for long periods, which is the situation where cold bites hardest. Insulation, a good shell and thermal accessories matter more than for active trades, and recognisable branding helps the public identify staff. Firms that arrange cover through an online security guard booking marketplace, or in-house, should state the clothing requirement for each post in the same way they state licensing and shift details, so winter kit is agreed before the first cold night rather than improvised.
Fit is a safety issue
Fit is often treated as a comfort matter. It is a safety one. The BSI guidance on inclusive PPE under BS 30417 is about selecting and issuing PPE that fits and protects a diverse workforce. Ill-fitting clothing increases the risk of tripping, entanglement and fatigue, and an oversized jacket can snag on equipment.
Winter adds a sizing trap. Staff wear bulky layers underneath, so sizes that fit in a showroom in a T-shirt are tight in January. Sizing should be checked with the full layering system on. Women’s and men’s cuts, different heights and different body shapes all need representation in the size run. A uniform fitting day is the practical way to do this before an order is placed.
Shrinkage is the other fit risk. Fleece and cotton-rich hoodies can change size after washing, so a test wash on a sample is cheap insurance. See our note on workwear shrinkage and test washing.
Fabric weight and construction
GSM, grams per square metre, indicates fabric weight. Heavier does not always mean warmer, because insulation, lining and weave all contribute, but weight tells you something about durability and handle. A lightweight polo and a heavy hoodie sit at opposite ends of the range. The GSM guide for procurement teams shows what to put in a specification.
Other construction details worth listing in a tender or order brief:
- Taped seams on outer shells for wet sites
- Reinforced elbows, shoulders and knees on high-wear roles
- Adjustable cuffs, hoods and hems to hold heat in
- Pockets sized for gloves and radios, accessible with gloves on
- Trousers that allow movement with thermal layers underneath, such as the Ultimate modular 3-in-1 trousers
How to order winter workwear without waste
- Write the role list. Group staff by where and how long they work outdoors. Each group gets a specification.
- Check the risk assessment. Confirm the hi-vis class, helmet and harness compatibility, and any rules for specific sites.
- Pilot a small set. Experts recommend trialling gear with a small, varied group under real conditions. This shows fit issues, restricted movement and PPE conflicts before a bulk order commits budget.
- Test wash. Wash sample garments to the care label and measure again.
- Plan the artwork. Decide logo size and placement for jackets, which differ from polo shirts. Approve a mockup before production.
- Hold a buffer. Keep spare outer shells, gloves and thermal socks. Without backup stock, staff are left exposed or wear unsuitable, non-compliant clothing, which undermines duty of care.
- Order early. Cold weather arrives before most budgets are approved. Ordering in early autumn leaves time for sampling, embroidery and delivery.
Judge cost over the garment’s life
The cheapest jacket is rarely the cheapest to own. Banner UK’s guidance suggests assessing procurement across the garment’s life cycle, not only the initial price. A shell that survives two winters costs less per month than one replaced after four months, and a jacket that fits properly is worn rather than left in the van.
Buying one bundle for the whole workforce is often a false economy, because it ignores fit differences. Choose by fit and role first, then use bulk pricing within each group.
Our perspective on winter uniforms
We see the same pattern each autumn. Businesses order the right garment in the wrong size, or a smart jacket that does not suit the work, or hi-vis that looks identical to last year’s but has not been checked against the current risk assessment. Branding is the visible part of a uniform. Fit, certification and compatibility with other kit are what make it function.
Our view is that winter workwear should be built from a few well-chosen pieces rather than a long list. A shell, a mid-layer, a base layer and accessories, each branded consistently, give a team a recognisable image and give managers fewer products to stock and replace. Embroidery and printing are decisions to make early, since logo placement affects how a jacket is cut, worn and layered.
We also encourage a sample stage. A short trial with a mixed group costs little next to a bulk order that turns out too tight over a fleece. Artwork mockups are approved before production, and showroom visits are available for buyers who want to handle fabrics before committing.

FAQ
What is the three-layer rule for winter work?
It means a moisture-wicking base layer, an insulating mid-layer such as fleece or softshell, and a windproof, waterproof outer shell. The system lets workers add or remove clothing as activity changes, which prevents sweat build-up and chilling.
What is the best workwear for winter?
It depends on the job. Outdoor trades need a waterproof, windproof shell with reinforced stress points, while supervisors and surveyors often do better with softshell hybrids. Gloves and thermal socks matter for every outdoor role.
Does winter hi-vis still need to meet a standard?
Yes. Warm hi-vis should conform to EN ISO 20471, with Class 3 the highest level of conspicuity. It must also fit with helmets, harnesses and other PPE, and be cleaned and replaced when damaged or faded.
Is there a legal minimum temperature for outdoor work?
No statutory minimum applies to outdoor work. Employers still have to assess the risk and provide suitable protection. For indoor workrooms, HSE guidance gives usual minimums of 16°C, or 13°C for strenuous work.
Can staff wear a hoodie under a safety helmet?
It is not advised on site. A hoodie worn under a helmet can compromise how securely the helmet fits. Use purpose-designed thermal headgear that works with the site’s required PPE.
