Workers across the UK are contending with exceptionally high temperatures this week, with many describing conditions akin to 'cats on a hot tin roof'. While some employers are implementing drastic changes to protect their staff, the absence of a legal maximum workplace temperature means many are left to endure sweltering environments as the heatwave grips the nation.
Ben Harrison, founder of a Gloucestershire-based solar panel installation firm, highlighted the intense heat his crews face daily. Working on rooftops, where temperatures can significantly exceed ambient air readings and reflect off steel surfaces, his teams are now starting at 06:00 BST and concluding their day by midday, a substantial reduction from their usual 16:30 finish. This adaptation, though costly to the business, is deemed essential for worker safety when rooftop temperatures are consistently above 35C.
Similarly, scaffolders in Bristol are feeling the impact. Lewis Winkworth and his team began their day at 06:00 BST on Wednesday, but by midday, the metal scaffolding tubes they handle were described as 'burning hot'. Despite the early start, the intense heat made little difference, compelling them to finish early. Their standard safety equipment now includes sun cream and ample water, alongside their usual harnesses and hard hats.
The challenges extend indoors, particularly for public transport operators. Darren Ford, who represents Bristol's bus drivers for the Unite Union, reported that drivers in older buses without air conditioning are experiencing cab temperatures well over 40C. With doors frequently opening at stops, drivers are 'cooking' in conditions akin to a sauna. While the bus company is modernising its fleet with air-conditioned electric vehicles, a significant number of older, uncooled buses remain in service, making shifts unbearable for drivers who can be sat for four to five hours at a time.
The Met Office has issued an amber warning for extreme heat covering much of England and parts of Wales, active until Sunday. Temperatures are forecast to remain high, with central and southern England potentially reaching 32C to 35C, while parts of Scotland and Northern Ireland will see temperatures in the mid-20s Celsius. The Met Office advises people across the UK to stay hydrated, seek shade, and avoid strenuous activity during the hottest parts of the day.
Despite these widespread issues, employment law expert Luke Menzies confirms there is no official maximum temperature for workplaces in the UK. While some protections exist for vulnerable workers such as pregnant or disabled employees, the general workforce is not covered by a specific heat threshold. This places the onus on employers to manage risks associated with heat, often leading to varied approaches across different industries and companies.
Practical safety advice during this period includes ensuring adequate hydration by drinking plenty of water, wearing light and loose-fitting clothing, taking regular breaks in cooler areas, and using sun protection for those working outdoors. Employers are encouraged to review their risk assessments and implement measures to mitigate heat stress, such as providing access to cool water, adjusting working hours, or offering fans and air conditioning where possible.
