Quick answer

National guidance
01

Who normally handles it?

An eligible healthcare professional working within their competence and responsible for the episode of care.

02

Is it mandatory?

Issue only after an appropriate assessment and in line with current fit-note guidance.

03

Is consent needed?

The note is normally given to the patient to share for its intended purpose.

04

Can the practice charge?

Usually not chargeable

In practice

Assess function, then give work-focused advice

A fit note records how a health condition affects fitness for work. It is not an occupational-health report, a benefits decision or a judgement about an employment dispute.

A focused consultation

Five questions that get you to a defensible decision

  1. What is the note for?

    Clarify whether this is for an employer, Statutory Sick Pay, Universal Credit, or a duplicate. These are not interchangeable requests.

  2. What does the person’s work involve?

    Ask about essential tasks, hours, travel, physical and cognitive demands, safety-critical duties and adjustments already tried.

  3. How does the condition affect function?

    Establish what the patient can and cannot do on a typical day. Assess relevant clinical and safety risks in the usual way.

  4. Could they do some form of work?

    Consider modified duties, altered hours, a phased return or workplace adaptations before deciding that no work is currently possible.

  5. What is the plan?

    Link the duration to expected recovery, treatment and a meaningful review point. Record the evidence and reasoning in the consultation.

  1. Assessment dateRecord when the assessment took place. This is not necessarily the same as the issue date.
  2. ConditionGive an accurate diagnosis where appropriate. A less specific description can be used if precision may harm the patient’s wellbeing or position with their employer.
  3. Fitness for workSelect “not fit” only when the patient cannot do any form of work. Otherwise consider “may be fit”.
  4. Functional adviceThe comments box is required for “may be fit”. Describe what the person can do and what should temporarily be avoided.
  5. Duration and reviewIn the first six months of a condition, one note can cover no more than three months. Choose whether a further assessment will be needed.
The key decision

“May be fit” or “not fit”?

Some work may be possible

May be fit for work

Use this when the patient could work if suitable changes are available. Add practical functional advice and select the relevant options:

  • Phased return
  • Altered hours
  • Amended duties
  • Workplace adaptations

If the employer cannot make the changes, the note is treated as “not fit”. The patient does not need a replacement note.

No work is currently possible

Not fit for work

Use this when your assessment supports that the patient cannot do any form of work at present—not simply because they cannot perform every part of their usual role.

Document the functional rationale, expected course and follow-up plan.

A useful comment answers three things

Function: what can the patient manage? Restriction: what should they avoid? Time: how long is the advice likely to apply?

“Avoid prolonged standing and repetitive lifting while symptoms settle; consider seated or lighter duties for the next two weeks.”
Common difficult situations

When the decision is not straightforward

01

Repeated requests

Do not extend automatically. Reassess current function, progress, treatment, barriers and the return-to-work plan. Longer absence may be justified, but each note still needs a clinical rationale and an appropriate review point.

02

Mental health

Avoid assuming either that work is always harmful or that it is always therapeutic. Consider symptoms, risk, job demands, support and the patient’s view. Some people benefit from modified work; others may be unable to do any work at that time.

03

Benefits or Jobcentre requests

A fit note can support a benefits claim, but it does not determine work capability. Clarify the exact request, keep the certificate clinically grounded and do not use it as a substitute for a Work Capability Assessment or bespoke report.

04

Symptoms out of proportion to findings

Normal investigations do not by themselves prove that a patient has no functional limitation. Reassess the clinical picture, function, red flags and wider barriers; make a plan and seek senior or specialist input where appropriate.

Explain the decision

Useful consultation wording

“My role is to advise how your health affects work. I cannot decide your employer’s policy, but I can describe the functional restrictions clearly.”

“The evidence today suggests that some work may be possible with changes. If your employer cannot make those changes, this note is treated as saying you are not fit for work.”

“Before extending the note, I need to review what has changed, what support has been tried and the plan for recovery or return.”
