I assume that they didn’t “get it” from anywhere, and that the rental materials they have are the same that MTI rents out to everyone, and that the director is choosing to set it in the underground as their own creative choice. There is no “London Underground” version of Into The Woods available.

For folks who don’t know, anyone putting on a musical has signed a contract with a licensing company. Different houses own the rights to different shows, so say I want to put up Into the Woods. I reach out to MTI who owns the rights to the show (link to MTI’s UK website, as I’m assuming the OP is in the UK).
I would then apply for the rights, which might or might not be granted based on what kind of organization I am, whether there’s a tour in the works that might be coming through my region, and all sorts of other things.
MTI would then offer me a contract based on projected ticket sales, house size, type of organization, and maybe some other details.
Then, they’ll send materials- scripts, and orchestra books, some fixed amount of time before show date. All those materials then must be returned at the end of the contract.
There are some shows that have other resources available for rental- tech packages and things like that. You can get a guide to the original West Side Story choreography if you want. But, most of the time, scripts and scores are what you get.
It can depend on the property and the scope of production, but some contracts have language that gets really specific about how you can or cannot deviate from the original staging. And if you want to make changes, you have to run them through the licensing company first. There are details here I’m not privy to, but earlier this year a Broadway revival of A Chorus Line was cancelled, maybe because of other 50th Anniversary productions the rights holders are interested in, and maybe because the scope of the re-imagining was not what they had originally approved.
Most of the time, school productions will just do whatever they do because rights holders don’t have the resources or inclination to police every production. But it’s likely breaking contract.
I just dug up an old MTI contract I had, which includes the following stipulation:
Changing the Play: Under federal law, you may not make any changes, including but not limited to the following:
a. You may not add new music, dialogue, lyrics or anything to the text included with the rented material.
b. You may not delete, in whole or in part, any material in the existing Play.
c. You may not make changes of any kind, including but not limited to changes of music, lyrics or dialogue or change in the period, characters or characterizations in the presently existing Play.
d. You agree that any proposed change, addition, omission, interpolation, or alteration in the book, music, or lyrics of the Play shall first be submitted in writing to MTI so that the written consent of the Authors, if granted, may be obtained by MTI.
