These Regulations, which apply to the whole of the United Kingdom, amend regulation 3 of the Branded Health Service Medicines (Costs) Regulations 2018 (S.I. 2018/345) (the “Statutory Scheme Regulations”). The Statutory Scheme Regulations, amongst other matters, make a scheme for the purposes of requiring specific manufacturers and suppliers of medicines for NHS use to pay amounts to the Secretary of State. These amounts are calculated by reference to the net sales income or estimated net sales income from supplies of such medicines.
