New Hallmarking Dealer's Notice To Be Introduced

27 Sep 2019

The Dealer’s Notice, which must be displayed by all dealers supplying precious metal jewellery, is being updated to add two new marks, in a version that will be compulsory from 1 May 2020.  

The updated version incorporates:

Legal requirement 

One of the requirements of the Hallmarking Act 1973 is that all dealers supplying precious metal jewellery (or other items made of precious metal) shall display a notice explaining the approved hallmarks.  

This must be the notice produced by the British Hallmarking Council (BHC).  

New version 

The Dealer’s Notice has been updated to incorporate: 

Online retailers 

The BHC’s view is that, although the Hallmarking Act makes no express reference to the internet, it applies to sales of, and other dealings with, articles made of precious metal conducted over the internet and accordingly dealers supplying precious metal articles online should display the Dealer’s Notice on their websites.  A suitable format for this is available.  

Dealer’s Notice from 1 May 2020 

From 1 May 2020 the revised version will be the only legally recognised notice.  

Following a 6 month period of grace this will become the only acceptable version as of 1 May 2020. This therefore replaces the previous version, last amended in 2015.  

How to get the new notice 

The new version is available as a free download from any of the Assay Office websites, you can find it here, and high quality printed versions are also available.  For those requiring large quantities of notices artwork is available for retailers to produce their own signs.  A version for online retailers is also now available.  

As previously, high quality hard copies of the Dealer’s Notice will be available from the Assay Offices for a charge of £15 plus VAT and postage.    

The new Notice is also available as a pdf file on our website, you can download it here

A format for display in online shops is available, together with guidance for its display. You can find it on the British Hallmarking Council website.

High resolution artwork is available electronically from each Assay Office, allowing retailers to print their own hard copies using a professional printer. Simply get in touch to receive a high resolution copy.

Reproduction of the electronic versions must meet specific criteria.  The Dealer’s Notice:
