You need a surveyor. Is the house on a hill, what sort of foundations has it
got and are any other similar houses locally having similar problems.. Some
older builds seem to be made to creep and the cracks widen and narrow as the
soil expands and contracts.

Hello. I have a back-to-back red brick mid terrace house in the UK. There
is a
large crack in an internal wall on the 2nd floor. The wall between the
bathroom and the bedroom. The crack runs diagonally up in a step pattern
from
the bottom corner where the wall joins the external wall. The crack is
visible
on both sides of the wall. It is no more than 5mm wide at its widest
parts. I
cants see signs of cracks on the walls below. Can this be due to the
support
of the 2nd floor weakening? Or is the wall bowing. Please can anyone help
me
work out what is happening and what might need doing to fix it please
