Training & Conference Facilities



Due to the Coronavirus outbreak, we have taken the decision to cancel all events and venue hire at Sheffield Assay Office, with immediate effect until the end of 2020.  We will continue to monitor the situation and follow advice issued by the Government and Public Health England.

All customers with existing bookings have been advised of the situation and alternative dates will be offered.

Please be assured that the Assay Office is otherwise fully operational and we will be actively accepting bookings for both Tours & Talks and venue hire for 2021 as soon as it is appropriate for us to do so.

Sheffield Assay Office offers a unique venue for training and conference facilities. Our headquarters here at Guardian's Hall have been purpose-built to meet our needs, and those of our clients, exactly. The ground floor of this impressive two-storey building is dedicated to assay, analytical and research services whilst the first floor is home to the spectacular hospitality suites, the library and our collection. We are throwing open the doors to invite you to join us here!


The office is able to provide bespoke training for members of the trade or other interested organisations on Hallmarking and Consumer Protection legislation. A full package of regular update training is available on nickel legislation and conformity.

Conferences, Meetings & Events

The facilities at Guardians' Hall are such that we can offer you a choice of suite, whether it is for a small meeting or a gathering for 80 guests. Our rooms are also ideal as an exciting training or recruitment venue, or as an impartial venue for mediation.
