The BMA have published two VAT advice notes (provided by MHA Larking Gowen) for the two main PCN structures they see being implemented – lead practice, and federation-led, and a really useful PCN calendar to help you plan the next couple of months. These are accessible via their PCN webpage, with the VAT guidance available under the toolkit tab.
The LMC would also encourage you all to view the meeting template advice, checklist and handbook in the same section on the BMA website if you haven't already.
