Display the Dealer’s Notice

A new version, released in September 2019, became compulsory on 1 May 2020.
Display this notice in your premises where customers can see it. This applies to online retail sites as well as bricks and mortar premises. Read further guidance on selling articles of precious metal on the internet.
