This guide is based on official NHS, GOV.UK, and ACAS guidance on fit notes and sick leave in the UK.
Can You Get a Sick Note the Same Day? (Quick Answer)
Yes, you can get a same-day sick note in the UK if a GP or qualified healthcare professional assesses you and decides it’s necessary. However, for the first 7 days of illness, you usually don’t need a fit note and can self-certify instead.
Important update (April 2026): Under the Employment Rights Act 2025, Statutory Sick Pay (SSP) is now payable from the first full day of sickness absence. The previous three-day waiting period has been removed, which means correct documentation, whether through self-certification or a fit note, matters from day one.

Get an Urgent Sick Note in the UK (Same-Day Options)
If you’ve been off work for more than 7 days and need to get a sick note online in the UK urgently, same-day options are available. Your fastest options are:
- Online GP services – often within hours
- NHS GP – same day (subject to availability)
In many cases, a digital fit note can be issued the same day after a consultation, without visiting a clinic.
What Is a Sick Note (Fit Note)?
A fit note (Statement of Fitness for Work) is a medical document confirming:
- You are not fit for work, or
- You may be fit for work with adjustments
Fit notes are used as official medical evidence for employers when you’re off sick for longer periods. They are also used to support Statutory Sick Pay (SSP) claims and, where relevant, benefit claims such as Universal Credit.
It is worth noting that a fit note focuses on your functional ability and work capacity, not on providing a detailed diagnosis. In fact, according to BBC analysis of NHS data, approximately 72% of fit notes issued in 2025 did not specify a reason for the sickness absence.

- NHS GP: Free (after 7 days of illness)
- Private online GP: Typically £20–£60
Prices may vary depending on urgency and provider. Some services may charge more for urgent or same-day appointments.
Can You Get a Sick Note for Less Than 7 Days?
Usually no.
Under UK rules:
- You should not need a fit note for the first 7 days
- You can self-certify your illness
Exception: Employer Requests
If your employer insists on a sick note before 7 days:
- You may need to request one privately
- A GP may charge a fee
According to the NHS, if your employer asks for evidence for the first 7 days of sickness, a healthcare professional may charge a fee for this. Your employer should pay the fee.
What If Your Employer Asks for a Sick Note Too Early?
According to ACAS guidance:
- Employers should accept self-certification for 7 days
If this happens, you can:
- Clarify company policy
- Provide a self-certification form instead
In practice, most employers accept self-certification without issue. If you believe your employer is acting unreasonably, ACAS offers free advice on workplace rights and dispute resolution.
Can a Sick Note Be Backdated?
Yes.
A GP can backdate a fit note if:
- You were already unwell
- You explain your symptoms clearly
This means you do not always need to obtain a fit note on the exact day your illness reaches the 7-day threshold. However, the healthcare professional must still assess your condition before issuing the note, backdating does not mean issuing a note without consultation.
Are Online Sick Notes Legal in the UK?
Yes, if issued correctly after consultation.
A valid fit note must:
- Be issued by a licensed healthcare professional
- Follow proper medical assessment
- Comply with UK medical standards
Important: Avoid websites offering “instant sick notes” without consultation, these may not be legally valid and could be rejected by employers.
Are Digital Fit Notes Accepted by Employers?
Yes, most employers accept digital fit notes (PDF/email) as long as they are issued by a registered healthcare professional following proper assessment.
How Long Is a Sick Note Valid?
A fit note lasts for the specific period stated on the note by the healthcare professional. There is no fixed maximum, the duration depends on the nature and severity of your condition:
- For short-term illnesses (e.g., infections, minor injuries), a fit note may cover a few days to a couple of weeks
- For longer-term conditions, a fit note may cover several weeks or months
- A fit note can be extended or renewed if your condition continues beyond the initial period
If your fit note expires but you are still unwell, you will need a new assessment and a new fit note to continue your sick leave.
Some fit notes are marked as “may be fit for work” with recommended adjustments. In these cases, your employer should consider whether the suggested changes (such as reduced hours, amended duties, or workplace adaptations) are feasible.

Common Conditions That Qualify for a Fit Note
You may receive a sick note for:
- Mental health issues (stress, anxiety, burnout)
- Infections (flu, COVID-like symptoms, food poisoning)
- Injuries or musculoskeletal pain
- Chronic conditions
Mental health conditions are now the most commonly cited category on fit notes where a reason is recorded. In 2025, more than 956,000 fit notes in the UK cited mental health and behavioural disorders, more than any other condition category.
The key factor is whether your condition affects your ability to perform your job. Healthcare professionals consider whether you can carry out the tasks required by your role, and whether any adjustments might enable you to work safely.
If a condition is long-term or recurring, it may qualify as a disability under the Equality Act 2010, meaning your employer has a legal duty to consider reasonable adjustments.
