The most usual approach to the valuation of the type of property is by references to rents; due to the decline of the bingo industry, open market rents are scarce. The valuation approach for rating for traditional cinemas has generally by rental comparison, with rents analysed using a percentage of gross receipts. There are a large number of poster advertisement sites around the country and these are rateable in the usual way if they involve the occupation of land. They can also be rateable under a special provision of the Local Government Finance Act 1988 if the exhibitor only has a right to show an advertisement rather than having a right to occupy land. Section 64(2) provides that a separate hereditament is created where the advertising right is out or reserved to any person other than the occupier of the land or where there is no occupation at all of the land but the right is out by the owner.
