Your commitment to hallmarking

The 1973 Hallmarking Act outlines the legal requirements for assaying, hallmarking and selling of precious metal items in the UK.

There are three main areas with which a retailer selling precious metal items to UK consumers must comply:

1. Ensuring items that are not exempt carry a recognised hallmark.

2. Ensuring precious metal descriptions are accurate.

3. Ensuring that the mandatory Dealers Notice is displayed for consumers.

To fulfil your legal obligation in point 3, Dealers Notice A provides you with a detailed explanation of the Hallmark and should be displayed in a prominent position when retailing pieces.

This notice can also be displayed on online retail sites as part of a standalone page detailing wider
information about product quality. Download a copy of Dealers Notice A for display here. 

Dealers Notice A

However, we are aware that Dealers Notice A is not ideal for the online environment, so we have developed Dealers Notice B in two versions, PDF and a short film as an alternative for online sales platforms where a dedicated page on hallmarking is not possible.
