Can anyone help building side extension on house and neighbours but when we go to boundry line to build side af extension the flue from next doors boiler is hangig over boundry line so when we build wall up we will be 2inch from front of balanced flue where do we stand do they have to move it as boiler been in over 10 years does this mean we have to pay to move it or can we just build gable and let them sort it out as this may stop the fumes releasing from flue.
Thanks Brian
