How to change or cancel an NHS hospital appointment

It’s a common misconception that your GP is the “gatekeeper” for your hospital schedule, but in reality, once a referral is made, the ball is in the hospital’s court.

Contacting your GP to change a specialist slot often leads to unnecessary delays and frustration for both you and the surgery staff.

Here is a comprehensive guide on how to take control of your healthcare schedule effectively.


1. Use the NHS App (The Fastest Method)

The NHS App is the most efficient way to manage appointments without waiting on hold. Most acute trusts are now integrated into the platform.

  • Step 1: Log in to the NHS App and navigate to the “Your Health tab.

  • Step 2: Select “Upcoming and past appointments” then “Hospital and specialist appointments.”

  • Step 3: View your active referrals and select the specific appointment.

  • Step 4: Choose “Ask to reschedule” or “Ask to cancel.”

Top Tip: Managing your appointments digitally reduces the administrative burden on the NHS and ensures you have a digital paper trail of your request.


2. Direct Contact: The “Human” Approach

If the app isn’t showing your appointment or you have specific questions, calling the hospital directly is your best bet.

Option A: The Consultant’s Secretary

If you have a complex condition or are seeing a specific specialist, the Consultant’s Secretary is the person who actually manages the diary.

  • How to find them: Check your original referral letter. If the name isn’t there, call the main hospital switchboard and ask, “Could you please put me through to [Consultant Name]’s secretary?”

  • Top Tip: Always ask the secretary for their direct dial number so you can bypass the switchboard in the future.

Option B: The Central Appointments Office

For general or first-time appointments, most trusts use a centralized Outpatient Appointment Centre (often linked to the e-Referral Service).

Trust Example Phone Number Purpose
East Kent Hospitals 03456 088 888 e-Booking (First Appointments)
East & North Hertfordshire 01438 284444 General Outpatient Enquiries
Your Local Trust Check website Search “[Hospital Name] + Appointments”

3. Online Portals and “Patient Hubs”

Many NHS Trusts have moved to digital-first systems like Patient Hub or DrDoctor. These are secure websites where you can view letters and manage dates.

  • Digital Letters: You may receive a text message with a secure link (e.g.nhs.my/hospitalname).

  • Online Forms: Some Trust websites have a “Cancel/Change my Appointment” webform. This is often found under the “Patients” or “Outpatients” section of their official site.


4. SMS Reminders (The Two-Way Text)

Most hospitals now send a text reminder 48–72 hours before your slot. Do not ignore these.

  • Many of these services are “two-way.”

  • You can often reply with keywords like CANCEL or REBOOK.

  • The system will automatically log your request, which helps the hospital offer that slot to someone else on the waiting list.


5. What to Have Ready Before You Call

To make the process smooth and avoid multiple calls, have the following details at hand:

  1. Your NHS Number: Found on any prescription or your NHS App profile.

  2. Hospital Number: Usually located at the top right of your appointment letter.

  3. Date and Time: The specific slot you are trying to change.

  4. Reason for Change: Be clear if you need a specific time of day (e.g., “afternoons only due to transport”).


Why You Must Notify the Hospital ASAP

Missing an appointment without telling the hospital is known as a DNA (Did Not Attend).

This is costly for the NHS and, more importantly, many Trusts have a policy where a single DNA results in you being discharged back to your GP. To get back on the list, you would have to start the entire referral process from scratch.

Summary Checklist

  • [ ] Check the letter first: Look for a direct department number.

  • [ ] Try the NHS App: It’s the 24/7 solution.

  • [ ] Call the Secretary: Best for specialized or ongoing care.

  • [ ] Do not call the GP: They cannot see the hospital’s live booking system.
