From 10th December 2021 until 26th January 2022 (this may be extended or changed) you will be able to self-certificate for up to 28 days if you are ill, instead of the usual 7 days. If employees are off work for 28 days or less, they do not need to give their employer a fit note or other proof of sickness from a medical professional, but instead can fill out a self-certificate.
Employees will still be required their employer a doctor’s ‘fit note’ (sometimes called a ‘sick note’) if they’ve been ill for more than 28 days in a row and have taken sick leave. This includes non-working days, such as weekends and bank holidays.
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.
