Paines Plough have an open submissions policy, here are all the details:
We read every play we’re sent and consider if for production. If you think we’ll like your play, email it to email@example.com along with your postcode and phone number, and we’ll give you a call to let you know it’s arrived safely.
Then within eight weeks we’ll let you know whether we want to produce it or not. Please note that when George and James are in production it can take a little longer for us to get back to you. We can only accept scripts by email so please don’t send us hard copies – we’re trying to save trees.
Please include your contact phone number when you send your play, as well as a completed Equal Opportunities form, which can be downloaded from the ‘Links and Downloads’ column on the right. For further information, please also download our Unsolicited Scripts FAQs document.
We do workshops all over the country too, so let us know where you’re based and we’ll get in touch when we’re local.
