Sadiq Khan backs calls for maximum workplace temperature in UK

The mayor of London, Sadiq Khan, is backing calls for a maximum workplace temperature as pressure grows on the government to protect workers from the impact of repeated Heatwaves across the UK.The extreme heat has left people struggling to cope as temperatures in some workplaces climb above 40C, causing thousands of schools to close and hospital and transport systems to break down.The June heatwave alone killed an estimated 440 people a day in the UK during its three-day peak.The UK has health and safety guidance on minimum workplace temperatures but nothing for maximums, despite rising summer heat caused by the fossil fuel-driven climate crisis.Trade unions and campaigners have repeatedly called for a maximum indoor work temperature, with Unison and the Trades Union Congress demanding a limit of 30C, or 27C for strenuous work.In May, a report from the Climate Change Committee, which advises the government, included a recommendation to set maximum work temperature regulations to address the increasing risks posed to “workers’ safety and incentivise the deployment of the necessary cooling”.At the weekend the pressure on the government grew when the Green party MP Hannah Spencer said she planned to introduce a bill in parliament that would pave the way for a workplace heat limit.Now a spokesperson for Khan, one of Labour’s most senior elected officials, has said he backs the idea as extreme heat is “becoming a growing reality” for people in the capital, which has been one of the worst-hit places during this summer’s Heatwaves.Khan has launched an initiative to help the city adapt to increasingly frequent and severe Heatwaves. His spokesperson said that although he did not have the power to introduce enforceable maximum temperature rules, he supported the idea.London has been one of the worst-affected places during this summer’s Heatwaves.

Garbett said too often headteachers in Hackney had faced a no-win decision – stay open, exposing staff and pupils to dangerous levels of heat, or close, knowing that many children do not have a better alternative at home“Urgent investment from the government in more resilient schools and public buildings isn’t just an issue of the climate crisis, it’s a matter of basic social justice,” she said. “Councils are ready to tackle the crisis and take on a statutory duty to lead the response, but we need the powers and – more importantly – proper funding to take action.”A government spokesperson said it had “no plans to introduce a mandatory maximum workplace temperature”, adding: “The Health and Safety Executive (HSE) has shared guidance for employers to plan for and support those working in extreme heat to keep workers healthy and safe.”However, they said the HSE would launch a public consultation on health and safety in the workplace this year that would look at temperature thresholds alongside a range of other issues.
