How long can I self-certify for?
Seven calendar days, including weekends. A fit note is needed from day eight.
Does my employer have to accept self-certification?
For the first seven days, yes — that is the standard arrangement. Some employers ask for more as a matter of company policy; if they do, they should not expect you to pay for it.
Is a private note as valid as an NHS one?
Yes. A fit note from any registered clinician who has assessed you is valid. It will show that it was issued privately.
Can you backdate it?
Only where it is clinically justifiable based on the assessment. We cannot certify a period we have no clinical basis to comment on.
Do I have to see a doctor for a fit note?
No — since 2022 nurses, pharmacists, physiotherapists and occupational therapists can all issue them. That often means a faster appointment at your own surgery.
Will you charge extra for the note?
No. It is included in the £40. And if you are within the first seven days, we will tell you that you do not need one at all.
