What you need to know as an employer

Isolation notes are for employees who:

  • have symptoms of coronavirus or have tested positive
  • live with someone who has symptoms or has tested positive, and the employee is not fully vaccinated
  • have been told to self-isolate by a test and trace service or the NHS COVID-19 app

Employees under the age of 18 years and 6 months only need to self-isolate if they have symptoms of coronavirus, or have tested positive.

Use your discretion around the need for medical evidence if an employee has been told to self-isolate because of coronavirus.

If you need evidence that an employee cannot work because of coronavirus, ask them to get an isolation note.

Employees who cannot work because of coronavirus should avoid asking their GP for a fit note. This is to let doctors focus on their patients.

If an employee is well enough to work, and can work from home, they do not need an isolation note.
