hi i'm just looking for some help please,i've got a vent at the top of
my roof that has two 5inch pipes coming down from it that then go into
the wall that joins my flat to my neighbours,my only thought was that it
serves to vent a space between our flats,that's if they even have a
cavity between the blockwork??you'll have to forgive my ignorance,if
possible i'd like to remove them

Do you own the flat?
You can't modify anything in a rental.
Do any of the other flats have the same setup?
If not, then the pipes may serve all the flats in your building.

Not to mention that even if they are unused and are entirely his,
removing a pipe going through a tile roof and properly restoring
the tile, etc, doesn't sound like a trivial task. That the pipes
apparently go into the wall between his unit and the next
strongly suggest they are there for some legitimate purpose,
like plumbing vents for example.
