Rates (Industrial Hereditaments) Order (Northern Ireland) 1997
Schedule 14 to the Rates (Northern Ireland) Order 1977 provides for the apportionment of the net annual value of a mixed-use hereditament between its use for industrial purposes and its use for other purposes. It further provides that where the overall net annual value of a mixed hereditament does not exceed £300, the hereditament will be treatment as if it were wholly used for industrial purposes. In such a case no apportionment need by carried out.
