Corona Virus Contingencies

We ask that customers do not send work into Assay if the items have come into contact with anyone who has, or is showing symptoms of, Covid-19. Government guidelines state that the virus can live up to around 72 hours when it is felt the risk from any contaminated surface would significantly decrease. Therefore please wait for this period to lapse before sending items that could potentially be contaminated.
Staff members are at high risk with numerous packets transferred to us every day. As a precautionary measure for our staff, we will no longer accept cash from Monday (16th March.)
