Can I leave the office if it’s too hot?

The UK recently has experienced its hottest July day on record, with temperatures reaching 38.1 degrees in some parts of the country. But the scorching-hot heatwave has raised the query in many offices – how hot does it need to get before we can go home?

In a nutshell, there isn’t a maximum temperature detailed in any health and safety legislation. However, workplace regulations do state that ‘temperatures in all workplaces inside buildings shall be reasonable during working hours’.

The Trades Union Congress (TUC) has issued guidance indicating that temperatures no higher than 30 degrees are considered reasonable.

Keeping your staff cool

Employers should be well-prepared for the summer months. Here are a few helpful tips for keeping your staff cool this summer:

  • Install air conditioning in the office

  • Relax the dress code – light, loose clothing is advised

  • Close the blinds to prevent direct sunlight hitting the office

  • Provide chilled water stations to keep staff well hydrated

  • Implement flexible working hours – early mornings and later evenings will be cooler
