In the UK, silver bullion bars are subject to VAT, which removes much of their investment potential. In addition, the production cost of silver ingots is relatively higher than for gold bars. We would recommend gold bars or coins, which are now exempt from VAT, and which we offer on this site. For information, silver bullion bars are invariably .999 silver, which means 999 parts per thousand pure. We do sometimes have a small selection of special 1 ounce bars and other weights available.
