As winter sets in and temperatures drop, cold weather brings real risks for workers both indoors and outdoors. From chilled warehouses to construction sites and delivery routes, being cold isn’t just uncomfortable — it can be unsafe. Th
Why Cold Weather Matters for Health & Safety
Cold weather affects both the body and the workplace. When working in low temperatures, people may experience stiff muscles, reduced manual dexterity, slower reaction times, and, in extreme cases, cold-related illnesses like hypothermia or frostbite. Exposure over time also increases the risk of slips and falls on icy surfaces and diminished concentration — all of which can lead to accidents.
Beyond physical hazards, cold temperatures can reduce productivity and raise the likelihood of errors, especially when workers are forced to rush or cut corners just to keep warm.
What the Law Says
Under UK law, employers must protect the health and safety of workers — and this includes managing temperature risks.
There’s no legal temperature threshold for outdoor work, but employers must still assess risks and take sensible precautions when cold weather could affect safety or health.
Assessing the Risk of Cold Weather
A cold weather risk assessment should form part of your wider health and safety planning. This means organising your workplace and work activities to reduce exposure to cold and considering factors such as:
If your assessment shows that cold may pose a risk, you must put controls in place. These might include providing breaks in heated shelters, adjusting work schedules, or changing how tasks are performed.
Practical Measures to Keep People Safe
Here are key steps that can make a big difference:
❄️ 1. Provide Appropriate Clothing and PPE
Warm, layered clothing helps workers maintain body heat. If tools or machinery must be handled in cold environments, consider insulated gloves and footwear to protect against cold stress.
☕ 2. Facilitate Regular Warm-Up Breaks
Offer access to heated rest areas and warm drinks so workers can recover from exposure. Frequent breaks in warmth help prevent hypothermia and maintain performance.
🧑🤝🧑 3. Plan Activities With Weather in Mind
Timing tasks for warmer parts of the day or rearranging workloads can reduce exposure. If conditions are severe, consider delaying non-urgent work.
🧠 4. Educate Workers on Symptoms
Make sure workers know signs of cold stress, such as persistent shivering, fatigue, confusion or numb extremities, so they can seek help early.
Cold Weather Outside the Workplace
Cold affects more than just work conditions. UK Government guidance encourages individuals and organisations to support vulnerable people — such as older adults or those with health conditions — during prolonged cold spells. This includes awareness of Cold-Health Alerts, preparation plans and communication of health risks to those at risk.
This broader advice, while focused on general health, reinforces the importance of preparedness and risk awareness during adverse cold weather.
Final Thoughts
Cold weather safety isn’t about making work cosy — it’s about protecting health, reducing risk, and ensuring safe, productive operations through the winter months. By understanding your legal obligations, assessing cold hazards, and putting sensible controls in place, employers can look after their teams and create safer, more resilient workplaces.
A proactive approach to cold weather is good for people, performance and compliance — and it sends a strong message that health and safety really does matter.
