I am selling a house and the chimney breast has been removed out of the dining room and bedroom approx 30 years ago. The problem I have now is the buyers have requested the building reg certificate, which I do not have. What can I do? I have looked int the loft and the chimney breast is still there, it is chased into the wall and the other part of the chimney is still there which is feed by the chimney in the lounge and 2nd bedroom which is still there. I cannot see any supports on the chimney where it has been removed in the past, should there be any?
