A petition calling for a legally enforceable maximum working temperature of 25C has been launched on the UK Parliament website, as Britain experiences its third heatwave of the year. The petition, started by Andrew Haddock, has gathered 555 signatures and remains open until December 2026.
Petition Demands Legal Cap on Workplace Heat
The petition seeks to introduce legally binding temperature limits for all workplaces, both indoor and outdoor. It states: "Currently, there is statutory guidance on a minimum working temperature, but there is no legal maximum cap, leaving staff vulnerable to extreme heat." This follows record-breaking temperatures in June 2026.
Current Heatwave and Health Alerts
The Met Office is tracking a prolonged period of hot, settled weather driving temperatures into the mid-30s across many areas. Amber and yellow heat health alerts have been issued by the UK Health Security Agency, with forecasts of highs of 35C or 36C. Deputy Chief Forecaster Tom Crabtree said: "Many people will understandably want to know how long the current heatwave is likely to last. While temperatures are expected to ease across southeast England through the weekend and into next week, it won't be a straightforward end to the warm weather."
Current UK Workplace Temperature Rules
UK law currently requires employers to maintain "reasonable" workplace temperatures but sets no maximum limit. The Health and Safety Executive recommends practical measures including fresh air, drinking water, air conditioning, and flexible working when heat causes discomfort.
Next Steps for the Petition
The petition needs 10,000 signatures for a government response and 100,000 for potential parliamentary debate. As of now, it has 555 signatures, with a target of 100,000 to trigger debate in Parliament.
