What have they done wrong here then, did they slap it on too thick?

Removing the wallpaper in my hallway and a big section by the front door has all come off, obviously eager not to repeat whatever mistake they made.

It's all going to be papered over again so I'm confident I can get it to a decent enough standard myself but the biggest area I've done before was a quarter of this size and hadn't previously failed so any tips appreciated

It hasn’t been keyed correctly and too thick in one application.
Get a plasterer to sort it out correctly.
Check the rest of the wall. Tap it, if it sounds hollow then it’s fked.

Are you steaming it off? Need to soak and gently remove

Some decorators loathe people taking paper off as they rip it off, attack with scraper and chunk the wall out. Be patient and use lots of steam, water spray etc

No comment on plaster but if you're papering it sounds like you can make it work

I used a steam wallpaper stripper once - never again! It popped the wallpaper off ok, but with the plaster attached!
That was my first lesson in plastering a wall. biglaugh

IMHO if that is all it took to get the plaster off too, then it needed to come off & be done properly.

Looks to me like the plaster didn't bond to the substrate. Either the wall was too shiny/impervious or too friable/dusty crumbly so the plaster has come off with a fine layer of wall?
So whatever you use you need to prep the wall so the plaster can stick. Maybe it needs abrading or scoring, maybe it needs some kind of primer?
A primer of some sort can help plastering by reducing the amount of water the wall sucks out of the wet plaster.

Personally I'm no plasterer, but I would attempt that with finishing plaster.
I'd use a good straight edge to make sure I wasn't over-filling.
If it doesn't come out perfect, finish off with Gyproc easifill.

It's worth checking over with straight edges and spirit level before you start, both the 'hole' and the good bit of the wall.
You don't want to fill the hole perfectly, but make an angle relative to the rest of the wall.
Checking the rest of the wall may tell you that some other areas of plaster are detached and bulging from the wall.

I don't disagree with that, it was just a shock at the time.
