We changed our Shopify Partners test store to Basic Plan to test some apps. Shopify docs advised you can't install paid apps using development sites.
We have since spoke with the Shopify App's company who have said that they can setup a free version of the app on our site for us.
Is it possible to change the site to be in Development mode? The UI / docs are unclear as to whether or not this is possible.

This is an accepted solution.
Nick here from Shopify. Good question!
Once a store has been moved from a development store to a paid plan store it isn't possible to change it back. Your best bet in this instance is to start another development store and duplicate the information over there.
I hope this helps and answers your question!
