Off-label use is use outside of the license that the drug has. In the UK formal approval for use of drugs for off-label indications would be via the commissioners. So either the ICBs or NHS England (for drugs used in specialised services). An example of the later would be the clinical commissioning policy for anakinra for HLH.
So this is essentially a budget decision rather than anything else.
Approval for rare diseases tends to be an exception because trials are not feasible.
But for more common things all these various levels of 'approval' make for both confusion and resentment.
