When fitting two bits of plasterboard butt up to each other can I just use filler in the join line and screw heads, plan on painting this, from reading various posts I’m under the impression I should be using tape after filling but is this just if you are skimming the entire board as the tape would make the filler proud?

Would filler crack once it’s all been primed and painted? I have been looking at the vids on taping and filling but concerned that the join will be visible due to being proud because of the tape and filler. I was unlucky with the size needed as I’m plaster boarding the top meter of the room and tiling Under that, the room measures 2500 and the sheet of plaster board is just under that other wise I could have run lengthways and got away with a join.
I guess it’s too late now, but you can get boards that are 2700 or 3000 long.

ah I didn’t know this, I thought 2.4x1.2 or 1.8x0.9 were the standard sizes, these were the only sizes available at wickes and b and q.
wont tape and filler on the join make the join line stand out? On the vids I’ve been watching they put 3 layers of filler on the tape and my concern is that even after sanding this and feathering the edges the join would look raised/bulged. Would the filler definitely end up cracking if I just fill the join gap and sand flush?
Use tapered edge boards.
To answer your question, yes it will crack if you fill the joints without reinforcing tape.
Can I use any filler over the scrim/join tape? I've seen you can get some that a purposely for this like the easyfil etc but will multifinish plaster be ok or another filler?

I didn't know that either!
No multifinish is not designed to be sanded...use easi fill or similar.
