You only need a doctor’s note if you are unable to work and are ill for longer than 28 calendar days. Your employer will provide you with an SC2 self-certificate form for shorter periods of illness.
Employees can take time off work if they’re ill. They need to give their employer proof if they’re ill for more than 28 days.
If they started their sick leave before 10 December 2021, they must give proof if they’ve been ill for more than 7 days.
If employees are self-isolating and cannot work because of coronavirus (COVID-19) they can get an ‘isolation note’ online from NHS 111. They do not have to go to their GP or a hospital.
