The vast majority of users keep their metal safely in the vault. When they sell, they receive cash in their BullionVault account which can then be withdrawn back to their bank account.
But you can also withdraw the metal. The fees vary according to the circumstances:
We only support withdrawal of whole 1,000 oz bars of silver bullion. The fee is 10%.
We only support withdrawal of whole kilograms of platinum. The fee is 10%.
We only support withdrawal of whole kilograms of palladium. The fee is 10%.
BullionVault gold, silver and platinum are all VAT (sales tax) free - for as long as they are held in our vaults. Upon physical withdrawal gold remains exempt, but 20% VAT then applies on silver and platinum.
