Coronavirus (COVID-19) Information
From Saturday 24th October, South Yorkshire will be in COVID Tier 3, but Sheffield Assay Office will remain open and we will continue to offer our customers a first class service.
Whilst the restrictions do not prevent us from opening, we are seeing more staff having to self isolate as a result of Track and Trace, which will inevitably affect our daily rate of production.
With immediate effect, and until further notice, our Early Hall and One Hour Service is being suspended.
We hope you all remain safe and well, and thank you for your understanding during these difficult times.
