Builders, bakers and cheeseburger-makers: the UK workers struggling in extreme heat

Workers across multiple sectors in the UK are experiencing severe challenges during extreme heat conditions, with temperatures exceeding 35C in London affecting those without access to air-conditioned environments.

Chefs, construction workers, bakers, paramedics, and bus drivers report that current working conditions pose significant health and safety risks. Kitchen staff at establishments like the Plimsoll pub in north London have resorted to unconventional cooling methods, including freezing tea towels and taking ice baths. Construction workers face particular vulnerability due to the age demographics of the workforce, with some continuing work well into their 60s. Bakers struggle with the combined effects of outdoor heat and large industrial ovens in often poorly ventilated spaces, while paramedics and ambulance technicians must maintain heavy uniforms regardless of temperature and continue working during periods of increased demand.

Bus drivers have vocalized frustration about inadequate air conditioning systems that frequently malfunction, with some taking industrial action. Cab temperatures can exceed 40C, and cooling attempts like small fans prove ineffective. Emergency service workers have requested permission to modify uniforms when temperatures reach specific thresholds to mitigate heat exposure.

Union representatives and worker advocates are pushing for legally mandated maximum workplace temperatures similar to standards in other European nations. Spain enforces temperature limits of 27C for sedentary work and 25C for light physical labor, while Belgium has tiered limits ranging from 29C to 18C depending on work intensity. The Trades Union Congress is advocating for requirements that employers take action when temperatures exceed 24C and that work cease at 30C, or 27C for strenuous activities.

Some employers have implemented additional measures such as relaxing uniform requirements, providing cold beverages, offering extra breaks, and reducing operational demands. However, workers in non-unionized settings report that employers continue normal operations without accommodations.
