Sick - Fit Certificates

I've Been Sick for 7 Days or Less

You do not need a doctor's sickness certificate for any illness lasting 7 days or less. Your employer may require you to complete a self-certification form which is available from your employer or on the HMRC Website.

Ive Been Sick for More Than 7 Days

If you're off sick for more than 7 days, you will need to give your employer a fit note. This is also called a Statement of Fitness for Work, from a healthcare professional.

Request a Sick/Fit Note - Please let us know the date you need the sick/fit note to start and how long you need it for.

How to count sick days

You need to count all days including any days you do not usually work as well as weekends and bank holidays.

For more information on Sick / Fit Notes please see Taking Sick Leave
