How many listed buildings have had demolition orders served on them in the past 12 months.

Demolition orders on listed buildings can be issued by local authorities in their capacity as the Building Control authority and on this basis, no information on the subject is held centrally. Historic Scotland has no formal role in such orders but in practice will often be consulted by local authorities before demolition takes place.
Listed building consent is also required for the demolition of a listed building and, as with building control matters, is dealt with by local authorities. Historic Scotland does have a statutory role in this process and must be notified by the local authority before such consents can be issued.
In addition, the Royal Commission for Ancient and Historical Monuments for Scotland must be notified when listed building consent is granted for the demolition of a listed building in order that the commission may make arrangements for the building to be recorded before works commence.
