Social distancing should form part of your business’s risk assessment and is one of the steps needed to make your workplace COVID-secure.
HSE has published information to help you put measures in place in your workplace to monitor, supervise and maintain social distancing. You must ensure that workers and other people visiting your workplace understand and comply with the measures.
Where possible you should keep people 2m apart. If this is not viable, keeping 1m apart with risk mitigation is acceptable.
