7 Day Sick Note: Self-Certification Rules & Requirements

Understanding the 7-Day Self-Certification Rule

UK employment law allows employees to self-certify sickness absences of up to 7 consecutive calendar days (including weekends and bank holidays). This means:

What is Self-Certification?

Self-certification (also called "self-cert") is when you confirm to your employer that you've been unfit for work due to illness, without needing a doctor to verify it. It's your legal right for absences up to 7 days.

What Makes a Valid 7-Day Self-Certification?

A valid self-certification document must include:

• Your full name
• Your employer's name
• The reason for your absence (general nature of illness)
• Start and end dates of absence
• Your signature and date

When Do You Need a Doctor's Note Instead?

You need a fit note from your GP if:

• You're off sick for more than 7 consecutive days
• Your employer's policy requires it (though this is rare and may not be enforceable)
• You're claiming certain benefits that require medical evidence

Generate Your 7-Day Self-Certification Note

Creating a professional self-certification note ensures your employer has all the information they need and demonstrates you're taking your absence seriously.

Common Questions About 7-Day Sick Notes

Can my employer demand a doctor's note for less than 7 days?

Generally no. UK law allows self-certification for up to 7 days. However, some employers may have specific policies. Check your employment contract, but such requirements are often unenforceable under statutory sick pay rules.

Do I need to provide evidence of my illness?

Not for self-certification. Your word is sufficient for absences up to 7 days. Your employer must accept your self-certification in good faith.

What if my 7 days crosses two different weeks?

The 7-day period is consecutive calendar days, regardless of which week they fall in. If you're off Thursday to Wednesday (7 days), you can still self-certify.

Can I self-certify multiple times in a year?

Yes. Each separate illness episode of up to 7 days can be self-certified. However, frequent absences may trigger occupational health reviews depending on your employer's policy.

What format should my self-certification take?

Many employers provide form SC2 (self-certification form), but you can also provide written confirmation. Using a professional template ensures you include all required information.
