Fit to Work Certificatelogo

It is not necessary to have a Doctor’s certificate until you have been absent continuously from work for seven days including weekends. After three days you must obtain a self-certificate (SC2) from your employer.

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. Download the Statutory Sick Pay: employee’s statement of sickness (SC2) form on GOV.UK

If your employer insists on a private certificate for an illness of less than seven days duration then the Doctor will charge a fee of £10.

If your illness continues for more than seven days then under the NHS your GP can issue an official statement (Med3) “fit to work certificate” to confirm your illness.
