Refer a patient

GP referral via e-RS

As part of the new NHS standard contract, we only accept referrals from GPs to consultant-led clinics through the e-RS.  Faxed or paper referrals will be rejected and will not be posted.

For rejected referrals, the GP will be informed within two days that their referral has been rejected.  It will then be the responsibility of the referring GP to resubmit the referral using e-RS.

NHS e-Referral service

If you wish to refer a patient, you can do it using the NHS e-Referral service (e-RS).

You can view available appointment slots and book the appointment before your patient leaves the surgery. If there are no clinic slots available via e-RS, you can still refer your patient to us by selecting the ‘defer to provider’ option on e-RS.

If the patient wants to arrange the appointment outside of the surgery, please make sure you give them their booking reference number and e-RS password.         

If you can’t find a service on e-RS, you can search for the condition or review the general service and the sub-specialty. 

As a specialist provider, some of our services are not offered by direct booking. These services can be accessed by emailing the referral to:

Patient transport

Please remember it is the GP's responsibility to assess the clinical need for any initial patient transport and for the provision of that first visit.

Consultant to consultant referral

Consultant to consultant referrals to our service can be sent via an email address to one of these email addresses:

The advantage of emailing a referral letter (with any diagnostic information) is that it will be received directly at a central point (Access Office), will be registered promptly and submitted for clinical review and appointed sooner. 

In the event of system failures, we may accept a faxed new patient referral using the fax numbers below:

  • Royal Brompton Hospital: 020 7351 8028
  • Harefield Hospital: 01895 828 695

Please note that these options are only for outpatient clinics held at either Royal Brompton or Harefield Hospital. Referrals for all other services must be submitted in the normal way.

Tertiary referral form

As a tertiary centre, we are reliant on referring providers to forward 18-week data, particularly with regards to clock start.

The Department of Health has devised an inter-provider transfer administrative minimum dataset (IPTAMDS) by which referring providers can transmit 18-week information.

We ask that all tertiary referrals made to this Trust are accompanied by an IPTAMDS form. Please complete this form and send it to the Trust with the usual standard letter. IPTAMDS data can be emailed to the following secure email address -

If you are unsure who to direct the referral to, please go to our consultants pages.

We will ensure that for all patients transferred out to another provider an IPTAMDS form is supplied to the recipient trust. 

Referrals to the inherited cardiovascular conditions service

Referrals to the Inherited Cardiac Conditions clinic (ICC) at Harefield should be made via e-RS in the normal way.
