Looking to fit a WC unit with concerned cistern and BTW toilet pan. I need to offset the concealed cistern by about 100-150mm to gain some space in the unit for vent pipe to run up. Will putting an extra bend in the flush pipe cause me issues ? Or any experiences of using flexible flush pipes ? Don’t want to go through it to find wont disappear

yes your right,
it may well cause flushing issues.
i did a standard LL/flush off set by 6" with a 90 deg bend and it wouldnt flush down properly. 2x 45deg worked though so may be just trial and error!
the flexible sounds better option.
