Protecting the Consumer and Servicing
the Trade with Independence and Integrity


The home of UK Hallmarking


welcome to the birmingham ASSAY oFFICE


While non-essential businesses have been forced to close, Government guidance states other businesses should continue to operate if they can do so safely.

To support the trade, and fulfil our statutory obligations, whilst operating in a safe environment for our staff, we are pleased to confirm that we have re-opened some of our operations, with skeleton staff, for Hallmarking, Gem Lab and AnchorCert Pro testing. 

Due to the Bank Holiday, we will be closed on Monday 25th May and will re-open on Wednesday 27th, Thursday 28th and Friday 29th May. Thereafter, we will continue to be open Mondays, Wednesdays, Thursdays and Fridays.   If you are delivering a parcel in person on a day when our customer service counter is not open please call 0121 592 1205 and a member of staff will be able to help.

The safety of our staff and our customers are our priority, and we shall continue to review and follow the guidelines and advice provided by the Government.

Royal Mail/Courier deliveries

We are receiving Royal Mail Special delivery parcels on the days that we are operational and we can also despatch parcels back to you by Royal Mail.  Similarly, we can also accept deliveries and despatch deliveries by Courier.

Customer Service Counter

If you wish to deliver your parcel in person, our customer services counter will be open from 10 am - 2 pm on the dates mentioned above.

Strict social distancing measures will be in place at the counter, which we would ask customers to observe at all times.  There will be clear markings on the floor to adhere to the 2-metre distance rules as well as a one-way queuing system.  We will also provide hand hygiene stations which customers will be required to use.

To help protect our staff, we can currently only accept card payments.

Please note that due to reduced staffing levels, and depending on the demand for the service chosen, our normal lead times may be extended.  

If you opted to have your parcel returned by a courier, please check their lead times which may vary.
