Can a Doctor Refuse a Sick Note in the UK? Rules, Rights & What to Do

Last updated: March 2026

If you’re wondering “can a doctor refuse a sick note in the UK?”, the answer is yes, but only in certain situations. A GP can refuse a fit note if they believe you are fit for work or there is no medical evidence supporting time off.

It can feel frustrating if you’re unwell and don’t get a sick note. But in the UK, doctors must follow strict medical guidelines when issuing fit notes. They can’t simply provide one on request.

This guide explains when a GP can refuse a sick note, your rights, and what you can do next.

Can a GP Refuse a Sick Note in the UK?

Yes. A GP can refuse a sick note in the UK if they believe you are fit for work or there is no medical evidence to support time off.

A GP can refuse a sick note (also known as a fit note) if:

• You are medically fit to work
• Your condition does not limit your ability to do your job
• There is not enough medical evidence

A fit note is based on clinical judgement, not patient request.

According to NHS guidance, a healthcare professional assesses whether you are “not fit for work” or “may be fit for work” before issuing a fit note.

When Can a Doctor Refuse a Sick Note in the UK?

1. You Are Fit for Work

If your condition doesn’t prevent you from working, your GP may refuse a sick note.

2. Your Condition Doesn’t Require Time Off

Some conditions can be managed while still working, especially with adjustments.

In these cases, a GP may suggest:

• Reduced hours
• Modified duties

Rather than issuing a “not fit for work” note, the GP may issue a “may be fit for work” note that recommends specific adjustments. This places a responsibility on your employer to consider those changes.

3. No Proper Medical Assessment

A GP usually needs a consultation (in-person or online) and enough medical information

before issuing a fit note. Without this, they may not issue a note.

4. Non-Medical Reasons

Doctors cannot issue sick notes for non-medical problems such as personal issues, workplace disputes, relationship difficulties or general stress that does not meet the threshold of a diagnosable condition. A fit note is a medical document, and its purpose is to confirm that a health condition affects your ability to work.

However, if a workplace dispute or personal difficulty has led to a diagnosable condition such as anxiety or depression, a GP may consider issuing a fit note based on that clinical assessment.

5. You’ve Been Off Work for Less Than 7 Days

A GP may also refuse a sick note if you have been off work for less than 7 days, as you are expected to self-certify during this period according to ACAS guidance.

Self-certification means you inform your employer that you are unwell. No medical proof is required for the first 7 calendar days (including weekends and bank holidays).

Important: Some employers may ask for evidence of sickness before the 7-day threshold, for example for the first day of absence. If this happens, the employer must cover the cost of any fee charged by the GP for providing such a note, they cannot pass this cost on to you.

However, it is worth knowing that doctors can issue a sick note from day 1 if clinically appropriate. This is common in cases of severe illness, mental health crises, post-operative recovery, or hospitalisation.

When a GP Will vs Won’t Issue a Sick Note

This depends on clinical judgement and your specific situation.

UK Sick Note Rules: What the Law Says About Fit Notes

In the UK:

• You can self-certify illness for the first 7 days (including weekends and bank holidays)
• After 7 days, a fit note is required

A fit note can state:

• “Not fit for work” – the healthcare professional believes you should not work at all during the specified period
• “May be fit for work” – you might be able to work if your employer makes reasonable adjustments

Guidance from GOV.UK confirms that fit notes focus on what you can do. not just time off. The system is designed to support a return to work where possible, rather than simply authorising absence.

What Is a Fit Note?

A fit note (Med3 form), officially called the Statement of Fitness for Work, is issued by a healthcare professional to confirm your ability to work. It replaced the old-style “sick note” in April 2010 across England, Wales, and Scotland.

It may include:

• Time off work
• Suggested adjustments (e.g. reduced hours)
• A recommended review date

Since 2022, fit notes can also be issued by:

• Registered nurses
• Pharmacists
• Physiotherapists
• Occupational therapists

This improves access across the NHS.

Important: Community pharmacists working independently in high-street pharmacies do not currently have access to the Med3 form and cannot issue NHS fit notes. Only pharmacists working within GP practices or hospital settings who have completed appropriate training can issue them.

What Should You Do If a Doctor Refuses a Sick Note?

If you’re wondering why a doctor refused your request, it usually means there wasn’t enough medical evidence to justify a sick note.

If your GP refuses, you still have options:

✔ Ask for an Explanation

You have the right to understand:

• Why it was refused
• What the medical reasoning is

A GP should be able to explain their decision clearly. If you feel the explanation is inadequate, you can raise a formal complaint through the NHS complaints procedure (in England, this is handled by the practice’s complaints manager or through NHS England).

✔ Request Work Adjustments

If you are marked as “fit for work” or “may be fit for work,” you may still:

• Ask your employer for reasonable adjustments to your role
• Use the GP’s advice as support for those adjustments
• Request a phased return, amended duties, reduced hours, or altered working arrangements

Under the Equality Act 2010, if your condition amounts to a disability (a physical or mental impairment with a substantial and long-term adverse effect on your ability to carry out normal day-to-day activities), your employer has a legal duty to make reasonable adjustments. Failure to do so may constitute disability discrimination.

✔ Seek a Second Opinion

You can speak to another GP within the same practice, register with a different practice, or use an online GP service. Private GP consultations are also an option, though there may be a fee.

Online sick notes carry the same legal weight as paper versions from your GP. Any GMC-registered doctor can issue a fit note, and your employer cannot refuse a legitimate digital fit note.

✔ Talk to Your Employer

Employers may accept alternative evidence of illness, such as:

• A letter from a hospital consultant
• A private medical report
• An occupational health assessment

Good employers will work with you to find a solution, even if a formal fit note has not been issued.

✔ Use Occupational Health

Your employer may refer you to an occupational health (OH) professional, with your consent, for an independent assessment of your fitness to work. Occupational health assessments can provide a different perspective from your GP’s, as they focus specifically on the relationship between your health and your ability to carry out your particular role.

It is worth noting that the Employment Appeal Tribunal has held that an employer can place “considerable weight” on what an occupational health report says (Kelly v Royal Mail Group Ltd). However, a GP’s fit note remains important medical evidence, and an employer should not disregard it without strong clinical justification.

Important: If your condition worsens, you can return to your GP for reassessment and request a fit note again.

When Should You Use a Sick Note?

A fit note is useful when:

• Your illness affects your ability to work
• You need time off beyond 7 days
• You require workplace adjustments
• You need medical evidence for SSP or benefit claims
• You are managing a long-term health condition that affects your job

Can an Employer Ignore a Sick Note?

In most cases, employers should accept a legally valid fit note as medical evidence.

An employer who disregards a fit note risks:

• Unfair dismissal claims at an employment tribunal
• Disability discrimination claims under the Equality Act 2010
• Health and safety liability if the employee’s condition worsens as a result of returning to work prematurely
• Breach of the duty of care owed to employees

However, a fit note is not a binding instruction, it is medical advice. An employer may seek additional medical evidence, such as an occupational health report, before deciding how to respond. But they should not act unilaterally or override a GP’s recommendation without strong and well-documented reasons.

If your employer refuses to accept your fit note, you should:

• Document the refusal in writing
• Contact ACAS (Advisory, Conciliation and Arbitration Service) for free advice on 0300 123 1100
• Consider raising a formal grievance through your employer’s internal procedures
• Seek legal advice if the situation is not resolved
