Updated 22 October 2026. The earlier implication that a proposed maximum temperature was a scheduled law change has been removed, together with the sales section.
A proposal for a maximum working temperature should not be reported as an enacted rule. For actual site decisions, use current official guidance and the responsible safety arrangements for the work.
Start with HSE
HSE's workplace temperature guidance explains that there is no single legal maximum working temperature. Its outdoor-working guidance addresses the risks of hot weather and practical controls.
The guidance includes considering cooler working periods, more frequent breaks and shade, access to drinking water and recognition of heat stress. Apply the full guidance in the context of the work; a short article cannot set a safe temperature or prescribe the right controls for a particular site.
Keep proposals and current requirements separate
When reporting a campaign, parliamentary question or proposed change, identify its stage and source. Do not say “before the law changes” as if a proposal has a certain commencement date.
A policy discussion is also not a reason to delay reviewing a current risk.
Communicate actual arrangements accurately
If you describe a project publicly, explain the measures actually in place and have the appropriate owner confirm the statement. Do not publish workers' personal information or turn a generic welfare claim into a safety assurance.
Keep the purpose clear
Worker protection is a site management responsibility, rather than a marketing opportunity. Any public account should reflect the real arrangements and direct readers to competent, current guidance.
