While Governmental advice regarding the novel coronavirus is advisory, I intend to maintain the Terms and Conditions as detailed on this page.
However, once mandatory advice is issued that impacts upon my assignments, I intend to do the following:
Not charge a cancellation fee for jobs cancelled after the advice becomes mandatory.
Not attend jobs that are not cancelled but ought to have been according to that advice. In those circumstances I would always contact the booker in advance.
Accept or turn down requests according to that advice.
