It's free, but you have to own the base game. It's best to have the GoG version of Fallout 4, as it must be BEFORE the next gen update, and be the GOTY edition that has all the DLC updates. It's possible on Steam, but difficult, with manual steps. (you first have to downgrade to the original version either with a downloaded "downgrader" or manually, manually manipulate files and directories and set manifests read-only so Steam doesn't keep putting back the Next Gen).

"Getting Fallout: London running on a Steam copy of FO4 can be a right palaver."
Impossible if the game was bought from Epic Store, as it's "incompatible" with their middleshitware.
You don't have to have GoG Galaxy, I downloaded the "backup installer archives" and installed it to the same wine prefix as my GoG Fallout 4. Then you have to run an installer.exe that finds your Fallout 4 installation.
Then, when you launch Fallout 4, the Fallout Launcher is in context of the Fallout London. You'll have to configure graphics and game settings anew.
But then there's a catch... the Launch button on the Launcher does indeed run the Fallout London mod, and it will work for the prologue (may crash in random spots) but after that, after a train ride from London Bridge Station after escaping this underground lab facility, it will never load you in game and if after several tries it does, it will crash very often. I couldn't get past that point, I tried like 10 times (others were saying they did after many tries) and was about to give up when I found a forum thread:

Instead, you have to run it through f4se_loader.exe (fallout 4 script extender) in the main "Fallout 4 GOTY" game directory instead, as the main executable. THEN it will be mostly stable. (I've had two crashes in near 12 hours of playing, and they were both when unexpected things happened, doing something unexpected, fumbling with the controls etc.)
I didn't follow all of those steps, I figured it out myself by looking at the executable names in the directory, and the only thing I had to do differently was run it through the script extender. My GoG installation was intact and the correct version, with no mods installed, so it didn't need a clean install. I'm not one for reading instructions
Anyway, it's like having a new, good old Fallout game (reminiscent of Fallout 3) where finding ways to traverse is a big part of the game. It's been refreshing and has kept my interest more than any of my other games right now. It's certainly worthy of having a mention here.
A VERY ambitious project. The city is awesome, and the voice acting is great. A lot of sinister British voices...
