Please use E-Consult in the first instance to request a sick certificate
Coronavirus
You do not need a sick certificate if you are isolating during the coronavirus pandemic, instead an isolation note can be obtained from https://111.nhs.uk/isolation-note/
Unfortunately we cannot supply sick certificates for patients who would prefer to stay away from their place of work during the pandemic. You should discuss this with your employer in the first instance around any concerns you may have or whether an alternative arrangement can be made for you.
Sickness lasting 7 days or less
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).
Your employer 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.
If you're sick and off work for more than seven days, your employer will probably ask for proof of your illness. Most employers ask for a fit note from your GP.
However, this will also depend on your employer's company policy on sick leave (or sickness absence). This policy should tell you how many days you can be off sick before you need to provide proof of illness or a fit note.
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.
Statement of Fitness for Work - ’Fit Note'
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.
