Why is there a minimum legal temperature for the workplace but no maximum temperature (in the UK)?
The minimum temperature laws only govern certain indoor workplaces of course, but they are there because cold conditions are generally more hazardous to health and also more common in the UK than high temperatures. That said, your employer still has legal a duty to provide you with a workplace that is safe to work in, and if high temperatures compromise a person’s safety then you are not obliged to work in such conditions. I would like to see a maximum of 26 degrees Celsius for offices. I suggest at your office you look to hire a portable air conditioner unit to keep the temperature down.
