In short. Rescheduling, cancelling and missed appointments are administrative events that carry a clinical cost because every unused slot could have gone to another patient. A cancellation with reasonable notice is ordinary; the same cancellation without notice removes a clinical opportunity that a finite service cannot easily replace.
Key points
- Almost every difficulty around cancellation is caused by silence rather than by the cancellation itself.
- A cancellation with reasonable notice is an ordinary administrative event.
- A short-notice cancellation usually cannot be refilled because assessment slots are long.
- One missed appointment usually brings an offer of a new time.
- Repeated non-attendance without contact may mean further appointments are not offered automatically.
The cost of a late cancellation
Appointments are a shared resource. Every slot that is booked and not used is a slot that could not be given to somebody else, and in surgical practice the cost of a late cancellation is larger than it first appears. A clinic slot cancelled at short notice usually cannot be refilled, because assessment appointments are long and cannot be compressed into a gap. The consequences widen from there. A cancelled pre-operative assessment may mean investigations are not complete in time, and the operation has to be postponed. A cancelled theatre slot may mean a list stands partially empty while staff, anaesthetic time and equipment are already committed. The patients who were waiting for that place wait longer.
Changing an appointment with notice
Contact the service as early as you can, using the same channel you booked through. Rescheduling is normally straightforward when there is notice: the slot is released, offered to another patient, and a new time is arranged. The earlier you tell us, the more likely it is that the slot can be reused, which in turn keeps waiting times down for everybody.
Missed appointments and repeated non-attendance
A missed appointment without notice is recorded. One missed appointment usually results in an offer of a new time. Repeated non-attendance without contact may mean that further appointments are not offered automatically, and that you are asked to re-enter the booking process. This is not a punishment; it is how a finite clinic protects capacity for the patients who attend.
Telling us early is the whole policy
Almost every difficulty around cancellation is caused by silence rather than by the cancellation itself. A cancellation with reasonable notice is an ordinary administrative event. The same cancellation with none is a lost clinical opportunity for somebody else.
| Situation | Who moves the appointment | What happens | What to do |
|---|---|---|---|
| Change with notice | You | The slot is released and offered to another patient, and a new time is arranged | Contact the service as early as you can, using the same channel |
| Cancellation at short notice | You | The slot usually cannot be refilled, so waiting patients wait longer | Give as much notice as possible |
| Missed appointment without notice | You | The miss is recorded, and one missed appointment usually brings an offer of a new time | Contact the service rather than waiting |
| Repeated non-attendance | You | Further appointments may not be offered automatically | Re-enter the booking process |
| Clinic moves the appointment | The service | A reason is given in plain terms and an alternative time is offered | Raise travel or leave concerns with the service |
| Clinical change | You | The appointment may move earlier, or you may be seen elsewhere | Contact the service and describe what is different |
What happens when the clinic changes your appointment?
Appointments are sometimes moved by the service rather than by you. Emergencies are added to operating lists, a complex case overruns, or a clinician is called away. When this happens, you should be contacted as soon as it is known, given a reason in plain terms, and offered an alternative time as close as possible to the original. If you have taken leave, or travelled for an appointment that is then changed at short notice, raise it with the service. It will not change what happened, but it is information the service should have.
What if something changes clinically?
Do not simply wait for the rearranged appointment if your condition changes in a way that worries you. Contact the service and describe what is different. A new symptom may move your appointment earlier, or mean that you should be seen elsewhere.
When should you contact the service rather than cancel quietly?
- Pain, swelling, redness or discharge that is getting worse rather than settling.
- A wound that has opened, or bleeding that restarts after it had stopped.
- Any symptom after a procedure that frightens you, however minor it seems.

Frequently asked questions
How much notice should I give to change an appointment?
As much as you can, using the same channel you booked through. Rescheduling is normally straightforward when there is notice: the slot is released, offered to another patient, and a new time is arranged. The earlier you tell the service, the more likely it is that the slot can be reused.
Why does a late cancellation matter more than it seems?
A clinic slot cancelled at short notice usually cannot be refilled, because assessment appointments are long and cannot be compressed into a gap. A cancelled pre-operative assessment may mean investigations are not complete in time and the operation has to be postponed, and the patients waiting for that place wait longer.
What happens if I miss an appointment without telling anyone?
A missed appointment without notice is recorded. One missed appointment usually results in an offer of a new time; repeated non-attendance without contact may mean that further appointments are not offered automatically, and that you are asked to re-enter the booking process. This is how a finite clinic protects capacity.
Risks & Limitations
- An appointment is not a diagnosis. Booking a slot reserves time with a clinician; it does not confirm what the problem is.
- A plan and an estimate are proposals based on the assessment. Either may change after examination, after tests, or after the findings at the time of treatment.
- Waiting times vary by surgeon, by complexity and by season, and an estimated wait can move when emergencies are added to a list.
- A consultation fee may apply and is separate from the cost of any treatment. An estimate for treatment is not a fixed quotation.
- Treatment may be declined, deferred, or reduced to a smaller option, and no outcome can be guaranteed.
When to Seek Care
- Sudden change in vision, or severe pain after any procedure — attend the emergency department or call the hospital directly.
- Fever, or redness and swelling that are spreading — seek urgent assessment rather than waiting for a routine appointment.
- Difficulty breathing, chest pain, or heavy bleeding that does not stop — seek emergency care immediately.
- A lesion that is growing rapidly, bleeding, or changing colour or shape — do not wait for a routine slot.
- Any symptom after a procedure that is worsening rather than settling.
