Figures are for patients waiting at the end of August 2026 (NHS England RTT, published 8 October 2026). They show how long people had waited so far, not how long a new referral will wait, and they are not a guarantee of any wait. A pathway is one patient’s wait for one specialty; a person can be on more than one list.

Can I choose a hospital with a shorter wait?
In England you have a legal right to start consultant-led, non-urgent treatment within 18 weeks of referral, with some exceptions, and you can usually choose where you are referred for a first outpatient appointment. Each hospital has a Patient Advice and Liaison Service (PALS) that can help with questions about your wait. Your waiting time rights explained.
Not medical advice. If your symptoms change or get worse while you wait, contact your GP or the team treating you. If it is not an emergency, NHS 111 online or calling 111 can tell you where to go, including urgent treatment centres, which often have shorter waits. Call 999 or go to A&E for life-threatening emergencies such as chest pain, difficulty breathing, severe bleeding or signs of a stroke.
