Assay Office Closed Friday 12th September 2025

As we come to the end of another financial year, I am once again extremely grateful to my staff, who continue to live and breathe Sheffield Assay Office. Everyone of them goes out of their way to go that extra mile to provide an exceptional service to the trade.

As a thank you to them, I will be closing the office on Friday 12th September, for staff training…. Ok, well there won’t be a lot of staff training, but I am taking them all to the St. Ledger Festival at Doncaster Racecourse!

I hope that our customers will be able to plan around our staff away-day and can confirm that we will be back open as usual on Monday 15th September.
