Workplace temperatures
While there is a legally enforceable minimum temperature in the workplace, there is not a corresponding maximum enforceable temperature.
The temperature in a workplace should normally be at least 16°C. If work involves rigorous physical effort, the temperature should be at least 13°C.
Outdoor work
Members who work outdoors include trolley collectors, backdoor staff and delivery drivers. Staff working outside should be provided with protective clothing and footwear to protect them from the elements, as well as having access to facilities such as hot drinks, warm indoor rest areas and somewhere to dry and store wet clothing.
If you're driving in winter conditions then check out our pointers and advice.
Work in cold rooms
People working inside freezers and chillers should have suitable protective clothing (providing several layers is best so that workers can adjust the level of protection to the work) and access to warm, dry accommodation for warm drinks and rest.
For work in freezers, it may be necessary to limit the time spent inside and to provide recovery periods.
Work in hot temperatures
Usdaw supports the TUC campaign for a legal maximum of 30°C (27°C for strenuous work). As the temperature rises above 24°C, heat exhaustion starts. People start to suffer loss of concentration, there are increases in accidents and loss of productivity. Symptoms include irritability, dizziness, headaches, nausea and fainting.
However, employers are expected to take reasonable steps to deal with situations where the temperature is uncomfortably high – this might include providing regular cold drinks, extending or increasing the frequency of break times and relaxing stringent dress codes.
