Your kitchen wall says 29 degrees, the Met Office alert pings, and you can feel the mood change at work. Someone goes quiet because they feel rough. Someone else rewrites your dress code with shorts and flip-flops. And at least one person is watching to see whether you notice. Heatwaves at work are not really about temperature, they are about trust.

We break down what UK employers actually need to know: there is no legal maximum workplace temperature, and the popular “30 degrees rule” is not law. What you do have is a duty of care under the Health and Safety at Work etc Act 1974, a requirement for a reasonable temperature under the Workplace (Health, Safety and Welfare) Regulations 1992, and the need for a risk assessment under the Management of Health and Safety at Work Regulations 1999. We also bring in the Equality Act 2010, because a one size fits all hot weather approach can disadvantage disabled staff, pregnant workers, older workers, and people on medication, creating a legal and wellbeing risk before you even reach for the thermometer.

Then we get practical. You leave with a five step plan you can action by Friday: a short written message that relaxes dress code and makes breaks flexible, discreet check-ins with higher risk staff, moving heavy or outdoor work out of the 11am to 4pm window, modelling water breaks so stopping feels normal, and a quick review to get ahead of the next heatwave. If you want a clear small business HR approach to heatwave safety, workplace wellbeing, and sensible adjustments, press play, then subscribe, share with another business owner, and leave us a quick review.
