LPB plan is to read them as they come in and identify those which they may be able to develop further through showcases, readings etc once things in the theatre world are back up and running. They’ll also use them to plan events and workshops – so for, example, if they spot some plays which have potential but need work on structure, they might programme a structure workshop they can invite you to or they might earmark a few brilliant shorts to showcase  for an event (they are also looking at online opportunities for those outside of London)

You’ll need to be a member of London Playwrights’ Workshop in order to submit your work but you can sign up for less than £4.
