Private Sick Note Guide for Employees in the UK

A sudden illness, painful injury or worsening health condition is difficult enough without worrying about work paperwork. This private sick note guide explains when you need a fit note, what a private clinician can provide, and how to handle the conversation with your employer clearly and confidently.

When do you need a private sick note?

In most cases, you do not need a medical note for the first seven calendar days of an absence from work. This includes days you would not normally work, such as weekends. You can usually self-certify your illness using your employer's process.

If you are off work for more than seven calendar days, your employer can ask for medical evidence. This is often called a sick note, but the formal document is known as a fit note or Statement of Fitness for Work. A fit note can be issued by an appropriate healthcare professional who has assessed your condition, including a private GP where clinically appropriate.

Your workplace may also have its own absence policy. Some employers ask employees to report their absence by a certain time, complete a self-certification form or send their fit note to HR. Checking this early can prevent avoidable stress later on.

A private fit note is medical evidence, not a guarantee of paid leave. Whether you receive Statutory Sick Pay or company sick pay depends on your eligibility and your employer's policy, rather than whether you were seen privately or through the NHS.

Private sick note guide: what happens at your appointment

A fit note should reflect a genuine clinical assessment. Your clinician will ask about your symptoms, when they began, how they affect your day-to-day function and what your job involves. For example, a back problem may affect a warehouse worker differently from somebody who works from home at a desk, while anxiety or low mood may make a high-pressure customer-facing role particularly difficult.

The appointment may be in person or, for some conditions, carried out remotely if the clinician feels they can assess you safely. This is always a clinical decision. A private appointment can be useful when you need prompt advice and cannot wait for a routine appointment, but a note is never issued automatically simply because it has been requested.

If you need examination, tests, treatment, a prescription or a referral, these can be discussed at the same appointment. The aim is not just to provide paperwork, but to understand what is going on and support your recovery.

Be honest about your symptoms and your work demands. Trying to minimise a problem can lead to advice that does not protect your health, while overstating symptoms can make it harder for your clinician to provide accurate certification.

Can a private doctor backdate a fit note?

Sometimes a clinician may be able to certify an earlier period if there is enough medical information to support it. However, backdating is not automatic. The clinician must use their professional judgement and may not be able to provide a note for dates they cannot reasonably verify.

It is best to arrange an assessment as soon as you realise your absence may go beyond seven days. Tell the clinician the date you stopped working, whether you have already self-certified and whether your employer has set a deadline for evidence.

What a fit note can say

A fit note may state that you are not fit for work. This is appropriate where your condition means that working would be unsafe, unrealistic or likely to delay recovery.

Alternatively, it may say that you may be fit for work with support from your employer. This can be especially helpful when a complete absence is not the only safe option. The note may suggest adjustments such as amended duties, shorter hours, a phased return, home working or avoiding heavy lifting.

The employer decides whether those adjustments are practical in the workplace. If they cannot reasonably accommodate them, you may be treated as not fit for work for the period covered by the note. A fit note opens a constructive conversation - it does not force an employer to create a role that does not exist.

What to tell your employer

Let your employer know as soon as possible that you are unwell and unlikely to be able to work. Follow your workplace reporting procedure, even if you are waiting for a medical appointment. You can explain that you will provide a fit note if your absence reaches the point where one is required.

You do not need to share every detail of your health history with your manager. A fit note may include a general diagnosis or clinical information, but you can keep conversations focused on what your condition means for work, how long the absence may last and whether any adjustments could help.

If your employer asks for information that feels unclear or intrusive, ask to see the relevant sickness absence policy or speak with HR. Clear, factual communication is usually more helpful than trying to manage the situation alone.

When a private assessment may be a good option

Private care can be particularly useful when you need a timely assessment, your symptoms are affecting your ability to work, or you would benefit from treatment and a plan rather than simply a certificate. It can also suit people whose work makes weekday appointments difficult, including parents, shift workers and those who need an appointment at short notice.

At Dunmow Private Medical Clinic, patients can be assessed promptly and personally for a range of common illnesses, injuries, musculoskeletal problems and ongoing health concerns. Where appropriate, your clinician can discuss fit note certification alongside practical treatment, medication, investigations or referral options.

Private care is not always necessary. If your condition is straightforward, you are within the first seven days of absence and you are managing safely, self-certification may be all you need. If you have severe symptoms, such as chest pain, signs of a stroke, serious breathing difficulty, heavy bleeding or a severe injury, seek urgent emergency help rather than waiting for a fit note appointment.

Prepare for your appointment

A little preparation helps your clinician give useful advice and decide whether a fit note is appropriate. Have the key facts ready:

• the date your symptoms started and the date you last worked

• details of your role, including physical tasks, driving, screen work or shift patterns

• treatment you have tried, medicines you take and any relevant medical history

• the date your employer needs evidence and any workplace adjustments already discussed

Bring or describe any hospital letters, test results or previous fit notes that may help explain the situation. If your condition has changed since an earlier assessment, say so. The most useful note is one that reflects your current health and your actual work demands.

Common questions about private fit notes

Will my employer accept a private fit note?

A fit note from an appropriately qualified private healthcare professional is valid medical evidence. Your employer may have a particular process for receiving it, so send it in the format requested and keep a copy for your own records. If there is uncertainty, ask HR which evidence they require rather than assuming.

Can I get a fit note for stress or mental health?

Yes, where a clinician's assessment shows that stress, anxiety, depression, burnout or another mental health concern is affecting your fitness for work. A supportive discussion may also identify adjustments that could make a return safer and more manageable. Mental health symptoms deserve the same careful assessment as physical symptoms.

How long can a private fit note cover?

This depends on the condition, expected recovery and the clinician's judgement. Some notes cover a short period with a review planned afterwards; others may cover longer where the medical circumstances support it. Your clinician should explain when to seek further review, particularly if you are not improving.

Needing time away from work is not a failure, and neither is asking for support to return safely. Prompt, compassionate medical advice can give you a clearer path through the immediate problem and help you make decisions that protect both your health and your livelihood.
