At UCLH, we may need to contact patients by telephone talk about an upcoming appointment, or discuss your clinical care, for example a telephone follow-up clinic.

The incoming number displayed on your phone will start with 0203. If you miss the call and phone the number back, you will hear a message saying:

“You have missed a call from the NHS. The person will attempt to call you back, no further action is required on your part.”

You will never see a call from us showing the service number directly. This is for confidentiality and to protect those patients who do not want friends or family to see the name of the service or number on the phone.
