Short definition

Self-certification is the process by which employees declare their own sickness absence for the first 7 days without needing a doctors note.

Detailed explanation

Self-certification allows employees in the UK to confirm they were genuinely sick for absences of 7 calendar days or less without requiring medical evidence. From day 8, a fit note from a doctor is required.

Many employers use a self-certification form (SC2 or company equivalent) to be completed on return to work. This documents the reason for absence and the dates absent.

Self-certification balances practicality (avoiding unnecessary GP visits for minor illness) with accountability for absence. The 7 days includes weekends and non-working days.

Frequently asked questions

Does 7 days include weekends?

Yes. The 7 days for self-certification is calendar days, not working days. So if you are off Thursday to the following Thursday, that is 8 days and requires a fit note.

Can my employer demand a fit note earlier?

No. Employers cannot require a fit note for the first 7 days. They can require self-certification but not medical evidence until day 8.
