When your GP suspects you need specialist care, they may refer you to a hospital consultant. But the process isn’t always straightforward — and delays can leave patients frustrated and unsure where to turn.
This guide explains how hospital referrals work in the UK, how long the process typically takes, what waiting time rules apply, how to check your referral, and what to do if you’re stuck on a waiting list.
What Is a Hospital Referral?
A hospital referral is when your GP or another NHS service sends your medical information to a hospital so you can be assessed by a specialist.
Common reasons for referrals include:
-
Evaluating new symptoms
-
Diagnosing long-term conditions
-
Surgery assessments
-
Diagnostic scans and tests
-
Mental health assessments
-
Cancer investigations (two-week-wait pathway)
Most referrals now go through the NHS e-Referral Service (eRS), which sometimes lets patients choose appointment locations and dates.

How the Referral Journey Works (Step-by-Step)
1. GP Identifies Need for Referral
After examining you or reviewing results, your GP decides specialist input is required.
2. Referral Is Submitted via e-Referral (eRS)
You may receive booking details, paperwork, or a booking code so you can choose an appointment slot.
3. Hospital Triage
A clinician reviews urgency and assigns priority.
4. Appointment Scheduling
You’ll receive a letter, call, text message, or eRS booking instructions.
5. Treatment Pathway Begins
After assessment, you might be discharged, monitored, or added to a surgical waiting list.
How Long Do Referrals Take in the UK?
Non-Urgent Referrals
The NHS aims for patients to start treatment within 18 weeks from referral. This is known as the Referral to Treatment (RTT) standard.
Backlogs mean many patients are waiting longer than 18 weeks, especially for planned operations and diagnostics.
Urgent Referrals
Marked urgent based on symptom risk, handled faster but not guaranteed within set timeframes.
Suspected Cancer (Two-Week-Wait) Referrals
Cancer referrals must follow a faster pathway:
-
Specialist assessment within 2 weeks
-
Treatment within 31–62 days (depending on stage)

Why Waiting Lists Are Long
Referral wait times increased substantially post-Covid due to:
-
Staffing shortages
-
Surgical and diagnostic backlogs
-
Ageing population
-
Limited specialist capacity
Millions remain on waiting lists for elective care in England.
How to Check or Track Your Referral
You can follow up through several routes:
✔ GP practice — confirms referral submission
✔ e-Referral paperwork — may allow booking or rescheduling
✔ Hospital referrals team — confirms triage status and expected wait
✔ NHS App — may show appointments and referrals (https://www.nhs.uk/nhs-app/)
Patients often assume GPs monitor referrals for them, but once accepted by hospital, responsibility shifts to the provider.
What to Do If Your Referral Is Delayed
1. Contact the Hospital
Ask whether they received the referral, if it’s been triaged, and what the current wait times are.
2. Request a Copy of Your Referral
Useful for escalation or private consultations.
3. Ask About Shorter Wait Times at Other Hospitals
Different NHS trusts have different waits. Patient choice may apply.
4. Consider a Private Consultation
Private diagnostics and specialist reviews can accelerate clarity and be shared back into NHS care.

Escalation Options If You’re Waiting Too Long
Ask Your GP to Review Urgency
If symptoms worsen, urgency may be upgraded.
Contact PALS (Patient Advice and Liaison Service)
PALS teams help resolve delays and administrative issues.
Make a Complaint to the NHS Trust

Ask About “Out of Area” Referrals
Sometimes possible if waits are exceptionally long locally.
Can You Choose Which Hospital You’re Referred To?
In England, patients usually have the right to choose hospital for first consultant-led outpatient appointments.
Mental health referrals follow slightly different rules. For more detail:

Private Referral Pathways
Private care can shorten:
-
Specialist appointments
-
Diagnostic imaging
-
Surgical consultations
Routes include self-pay or insurance. Reports can often be shared with NHS teams.
