But Is Your Workplace Ready For The Heat?

We're heading into our third official heatwave of 2025, with temperatures soaring into the 30s. Great for the beach, a barbecue with friends, or a leisurely swim - but not so much for productivity.

This week's heat is expected to peak in the South East and parts of central England, lasting 4–5 days, with humid nights and sweltering afternoons. So what approach should managers take to keep their teams happy, healthy and on track?

What Does The Law Say?

There's no legal maximum temperature for UK workplaces, or obligation to relax uniform or dress code requirements during hot weather, but employers are required to maintain “reasonable” working conditions. 

That includes:

✔️ A duty of care to protect employee wellbeing—both in the workplace and for remote workers.

✔️ Conducting risk assessments for heat stress.

✔️ Providing drinking water and adequate breaks.

✔️ Considering adjustments to uniforms or dress codes.

💡Top Tips

  • Consider allowing flexible working hours to avoid peak heat times.

  • Offer remote working options where feasible.

  • Relax dress codes to enable cooler clothing options.

  • Make sure that staff working outside wear appropriate clothes and use sunscreen to protect from sunburn.

  • Ensure regular hydration by providing plenty of water throughout the day.

  • Improve ventilation with fans or air conditioning.

  • Public transport can be adversely affected during a heatwave, so encourage staff to check timetables in advance.
  • For those staff who work remotely, you could offer more flexibility to work in whichever environment they find most productive. 

  • Consider offering more frequent rest breaks for workers who may be more affected by the heat than others - for example pregnant women, those on medication or with disabilities.
