I think this is the Sussex document. It has a start date of 1/4/22.

This is what it says about interim support:
2.2 Local defined outcomes
The desired outcome is that the additional needs of the TNBI population is met and that there is equity of access to services across Sussex, namely
• Initial support around gender identity issues
• Interim support whilst awaiting or under specialist services
• Provision of ongoing prescriptions of hormonal treatments as recommended by specialist GICs
It's not clear what 'interim support' means, but could be psychological support. Prescribing hormones is only mentioned in the context of ongoing prescriptions which have been prescribed initially by specialist clinics.
And about prescribing:
3.3.4 PART A – HORMONAL PRESCRIBING AND MONITORING
This LCS is not designed to promote the initiation of hormonal treatment in general practice. Regarding requests for the provision of ‘bridging hormones’, GPs should be mindful of relevant national guidance (RCGP position statement, GMC guidance, BMA guidance). Any decision to prescribe bridging hormones is a matter for the individual prescribing clinician.
In all cases, prescribing is at the discretion on the individual GP, and should only occur if the GP
• feels they have the relevant competencies to proceed
• is satisfied that any advice from secondary care or private providers is clinically appropriate
It also says: It is recognised that not all Sussex GP practices will be able or willing to provide this service. So presumably practices are free to opt out of this without penalty.
