How to submit a referral
e-RS referrals
All NHS GP referrals must be submitted using the NHS e-Referral Service (e-RS). Referrals sent by email or post from NHS GPs will not be processed.
Non-e-RS referrals
In line with NHS England's Digital First approach, we encourage all external non-e-RS referrals to be submitted digitally.
Digital referrals help reduce delays, improve traceability, minimise the risk of lost or incomplete information, and support safer patient care.
Please submit referrals by email to gstt[email protected].
We will continue to accept paper referrals where necessary. However, referrers will be advised to use digital referral methods in future.
2-week wait (2WW) referrals
For urgent 2-week wait (2WW) referrals from an NHS GP please use the NHS e-Referral service (e-RS) only. We cannot accept referrals sent by email or by post.
For 2WW referrals from other health professionals, please email [email protected].
