Self Certification Sick Note for less than 7 days

Seven consecutive days off sick or less

If you’re off work sick for seven consecutive days or less, your employer shouldn’t ask for medical evidence that you’ve been ill. Instead they can ask you to confirm that you’ve been ill. You can do this by filling in a form yourself when you return to work. This is called self-certification.

What is self-certification?

Self-certification is a way to prove that you were ill or injured and needed to take time off work to recover. Not all employers ask their employees to self-certify on their return – a fit note is usually enough to prove you were unwell.

Self-certification form

If your employer asks you to complete a self-certification form, you should provide as much detail as you can about the:

  • reason you were off — including information about your illness or injury;
  • causes of your illness or injury;
  • dates your sickness started and ended.

Many employers have their own self-certification form, but HM Revenue and Customs have created a form template, which is publicly available should your employer not have one.
