NHS Telephone Appointment: They Didn't Call or Are Running Late
You were told a clinician would ring at a set time, you have kept your phone free, and the time has come and gone. This is a common experience with hospital telephone clinics. Here is what usually causes it and how to reach the right team without losing your appointment.
Why telephone appointments run late
Clinicians in telephone clinics see patients back to back. If an earlier conversation needs more time, every later call moves back. Trusts say this openly: Guy's and St Thomas' notes there may be a short delay if a clinician needs longer with another person, and Royal Devon's patient leaflet apologises that delays may occur in these clinics.
Late is not the same as cancelled. A late call does not by itself mean your appointment has been dropped.
The call may not look like the hospital
Hospital calls often show as 'no caller ID', withheld, or a number you do not recognise. If your phone blocks withheld or unknown numbers, the call may never ring through. Some trusts ask you to tell them in advance if your phone rejects withheld numbers.
How long should I wait before chasing?
It depends on the trust, so use the instructions on your letter first. As an example of local practice, Royal Devon asks patients to ring the switchboard if they have not had a call more than 60 minutes after the appointment time. Other trusts set different arrangements, and some booking systems tell you the call will come within a window rather than at an exact time.
We do not give a universal waiting threshold, because there isn't one.
What to do if nobody has called
- Check the letter, text or patient portal message for a department phone number and any instructions about delays.
- Check your phone allows withheld and unknown numbers, and that you have no missed calls or voicemails.
- If the trust's stated waiting time has passed, ring the department on your letter, or the hospital switchboard and ask to be put through to it.
- Have your NHS number or hospital number and the appointment date and time ready.
- Ask them to confirm the phone number they hold for you; a wrong number is a common cause.
- If the call was missed, ask how it will be recorded and when you will next hear. Do not assume it has been rebooked automatically.
Missed a call from the NHS? · What happens if I miss an NHS appointment?
If you missed the call
How a missed telephone appointment is recorded and followed up depends on the service and its local access policy. Some clinicians move on to the next patient and the department contacts you afterwards; others try again. Ring the department as soon as you can and explain what happened.
This guide explains administrative processes only. If your symptoms change or get worse while you wait, contact your GP, NHS 111, or the clinical team named on your letter.
Frequently asked questions
Short answers first. Tap a question to read more.
My NHS phone appointment is late. Has it been cancelled?
Not necessarily. Telephone clinics commonly run behind. Check your letter for the trust's instructions and contact the department if the stated waiting time has passed.
Is there a national rule for how long the NHS can be late for a phone appointment?
We are not aware of one. Trusts set their own arrangements; Royal Devon, for example, asks patients to call if there has been no call more than 60 minutes after the appointment time.
Why did the call come from a withheld number?
Many hospital phone systems present as withheld or unknown. If your phone blocks these, tell the department in advance or change the setting for the day.
Can I ring the number back?
Some trust numbers cannot take incoming calls. Use the department number on your letter or the hospital switchboard instead.
