Sick Note / Fit Note

Alex By Alex · 12-year UK recruiter · Updated April 2026

In recruiter context

Officially called 'Fit Note' since 2010 (replacing 'Sick Note'). Issued by GPs, hospital doctors, nurses, occupational therapists, pharmacists, and physiotherapists since changes in 2022. Two options on the form: 'not fit for work' or 'may be fit for work' (with suggested adjustments). The first 7 days of illness are self-certified (no fit note needed). UK employers must accept fit notes; some operate stricter internal requirements. Fit notes can be backdated up to 7 days. Lost fit notes can be replaced by the issuing GP for free.
