UPDATE - 24/03/20
In light of the newer safety precautions outlined by the government, and after very careful thought, I have taken the decision to remain open, however I will not be making any more orders at this time or for the foreseeable future from my suppliers. This means I will not be accepting any new deliveries to my workshop.
To reiterate - I work alone, I wear a mask, I sanitise my working area and have access to clean water and soap within my workshop to wash my hands and any necessary equipment. All the materials I have in my workshop have been within my workshop now for 14 days or longer.
