We've gathered a few pages with lots of helpful advice about the uncertainty of working in theatre and the arts during this difficult Covid-19 outbreak. You can read about income support, tax relief, funding opportunities and mental health advice (which is handy for anyone, not just for us thespians).
Society of London Theatre
UK Theatre (who have also been hosting webinars offering advice - follow them on Twitter for updates)
Exeunt Magazine (featuring an impressive list of distractions if you aren't quite in the headspace to think about work!)
