An NHS sick note, officially called a "Statement of Fitness for Work" or "fit note," is a document issued by a registered GP or hospital doctor stating whether you're fit or unfit for work due to illness or injury.
What a Fit Note Shows
An NHS fit note includes:
- Whether you're "not fit for work" or "may be fit for work with adjustments"
- The reason for your absence (can be general, e.g., "viral illness")
- How long the note covers (or when you'll be reassessed)
- Suggested workplace adjustments if you're partially fit
When Do You Need an NHS Sick Note?
You need a fit note from your NHS GP or hospital doctor if you're off work sick for more than 7 consecutive calendar days.
Counting the 7 Days
The 7 days include weekends and bank holidays:
- Off Monday to Sunday (7 days) = Self-certification valid
- Off Monday to Monday (8 days) = NHS fit note needed from day 8
How to Get an NHS Sick Note
1. Contact Your GP Surgery
Most GP practices now offer multiple ways to request a fit note:
- NHS App: Request a sick note online through the NHS App
- Telephone: Call your surgery and request a sick note consultation
- Online: Many practices have online sick note request forms
- In-person: Book an appointment if required
2. The GP Assessment
Your GP will assess your fitness for work. This is often done by phone - you usually don't need to visit in person. They'll consider:
- Your medical history
- The nature of your illness/injury
- Your job requirements
- Whether adjustments could help you return to work sooner
3. Receiving Your Fit Note
Your GP will issue the fit note electronically and either:
- Email it directly to you
- Make it available on the NHS App
- Send it to your employer (with your permission)
- Make it available for collection from the surgery
NHS Self-Certification (1-7 Days)

Benefits of Self-Certification
- No NHS appointment needed - Saves NHS time and resources
- Instant - Don't wait for GP availability
- Free - No need to take time off to visit surgery

Common Questions About NHS Sick Notes
Are NHS sick notes free?
Yes. Fit notes issued during NHS consultations are always free. Private sick notes from private GPs may incur charges.
Can I get an NHS sick note backdated?
Sometimes. GPs can backdate fit notes if they have evidence you were unwell (e.g., medical records, hospital admission). They typically can't backdate beyond the date they first saw or spoke to you about the illness.
What if I can't get an NHS appointment quickly?
Explain to your GP surgery that you urgently need a fit note. Most offer same-day telephone consultations for this purpose. If you're struggling, contact NHS 111 for advice on alternative options.
Can my employer contact my NHS GP directly?
Not without your explicit written consent. Your medical information is confidential under GDPR and NHS rules.
Do I need an NHS fit note for Statutory Sick Pay (SSP)?
Only if you're off for more than 7 days. For 1-7 days, self-certification is sufficient for SSP claims.
