The Noël Coward Foundation has awarded £65,000 to help organisations including London’s Bush Theatre and Manchester’s Royal Exchange during the pandemic.
Other organisations that have benefitted include the Kiln Theatre in London, the Lowry in Salford, Mousetrap Theatre Projects, Theatre Peckham, Wise Children, Traverse Theatre in Edinburgh, the Mono Box, Imaginate and Salisbury Playhouse.
The funding has been used to support online streaming of cancelled projects and education work, and for administrative help.
It is in addition to a recent donation from the foundation to Acting for Others.
Alan Brodie, chair of the Noël Coward Foundation, said: "During these very challenging times, we are very pleased to be able to make further funds available to provide financial support to organisations affected by Covid-19.
"This is only a drop in the ocean for what is needed and we urge the government to provide the necessary funding to ensure the survival of these vital organisations who do so much for their communities and for the wider economy."
Brodie added: "The Noël Coward Foundation is entirely dependent on royalty income from producing Coward works and our funds are finite.
"No theatre means no royalties and therefore zero income for the foundation, resulting in the Noël Coward Foundation being unable to continue funding essential projects. That is just one example of the devastating effect the loss of live theatre has on the industry."
