Fit Note Sickness Certificate
You do not require a doctor's sickness certificate for any illness lasting seven days or less. Your employer may however require you to complete a self-certification form (SC2) which is available from your employer or on the HMRC website.
Evidence that you are sick
If you are sick for more than seven days, your employer can ask you to give them some form of medical evidence to support payment of SSP (statutory sick pay).
It is up to your employer to decide whether you are incapable of work. A medical certificate, now called a 'Statement of Fitness for Work’ (see below) from your doctor is strong evidence that you are sick and would normally be accepted, unless there is evidence to prove otherwise.
You could also provide evidence from someone who is not a medical practitioner, e.g. a dentist. Your employer will decide whether or not this evidence is acceptable. If your employer has any doubts, they may still ask for a medical certificate from your GP.
The practice will not provide a medical certificate for patients requiring self-isolation for coronavirus. Government guidance on coronavirus (COVID-19) is that employers use their discretion around the need for medical evidence for a period of absence where an employee is advised to stay at home either as they are unwell themselves, or live with someone who is, in accordance with the public health advices issued by the government.
Should your employer ask for documentation, you can now get an isolation note from NHS 111 online or you can download and complete this form this form (Word format) or in pdf format yourself and pass to them.
Statement of Fitness for Work
The 'fit note' was introduced on 6 April 2010. With your employer's support, the note will help you return to work sooner by providing more information about the effects of your illness or injury.
