What Is a Sick Note & When Do You Need One? Complete UK Guide
A sick note, officially known as a fit note in the United Kingdom, is an essential document when illness prevents you from working. Introduced in 2010, the fit note protects your income, supports Statutory Sick Pay (SSP) claims, and provides employers with formal medical confirmation of your condition.
If you have ever worried about losing pay, job security, or facing questions after taking time off sick, this document is your safeguard. While UK law requires a fit note after 7 consecutive days of sickness, many people now choose fast, private online options like

to avoid NHS waiting times and appointment delays.
This complete guide explains what a sick note is, when it’s legally required, and how to get one quickly online.
What Is a Sick Note (Fit Note)?
A fit note replaced the old sick note system to focus on what work you can do, not just what you cannot. It is issued by qualified healthcare professionals such as GPs, nurses, or physiotherapists.
The note will state either:
- “Not fit for work”, or
- “May be fit for work” with adjustments such as reduced hours, lighter duties, or remote work
What a Fit Note Includes
- Your personal details
- Brief medical condition summary
- Recommended absence or adjustment period
- Doctor’s name, registration number, signature, and verification details
Legal Status in the UK
- Required for Statutory Sick Pay (SSP) from day 8 onwards
- SSP can be paid for up to 28 weeks
- Valid in digital (PDF) or printed form
Online PDFs issued by licensed doctors—such as those from

are widely accepted by UK employers when printed or emailed.
Unlike self-certification (days 1–7), a fit note proves ongoing or serious conditions such as flu, injuries, stress, anxiety, or recovery from surgery.
When Do You Need a Sick Note for Work?
UK employment rules are straightforward, but employer policies may vary.
You Must Provide a Fit Note When:
- Your sickness lasts more than 7 calendar days
- You are claiming Statutory Sick Pay (SSP)
- You have a long-term or recurring condition
Common Reasons Employers Request One
- Flu or viral illness lasting over a week
- Back pain or musculoskeletal injuries
- Migraines or chronic headaches
- Stress, anxiety, burnout, or depression
- COVID-19 recovery or post-viral fatigue
Without a valid fit note, employers can legally withhold SSP from day 8 onward.
Some workplaces (e.g. healthcare, education, safety-critical roles) require a certificate from day one. Online platforms like

specifically issue Sick Leave Certificates for work, school, and university absences due to physical or mental health conditions.
UK Legal Requirements for Sick Notes
Under the Social Security (Incapacity for Work) legislation, a fit note is required to confirm medical incapacity for benefits and SSP.
Key Legal Points
- Self-certification covers days 1–7 (SC2 form or employer form)
- SSP rate (2025): £116.75 per week
- Paid by employer if you earn £123+ per week
- Extended sickness may require renewal every 4–12 weeks
Telemedicine services comply with UK law by issuing certificates that include full doctor credentials and verification contact details.
