7The compensation payable by the local housing authority to the dispossessed proprietor in pursuance of section 389(1)(a) shall be at an annual rate equal to one half of the gross value of the house multiplied by the appropriate multiplier.
8Subject to the following provisions, the gross value of a house for the purposes of this Part of this Schedule is its gross value for rating purposes as shown in the valuation list on the date when the control order comes into force.
9(1)If the house forms part only of a hereditament, the gross value of the house is such proportion of the gross value shown in the valuation list for that hereditament as may be agreed in writing between the local housing authority and the person claiming compensation.
(2)If any dispute arises under sub-paragraph (1), the authority or the person claiming compensation may by means of a reference in writing submit the dispute for decision by the district valuer.
10If the house consists or forms part of more than one hereditament, the gross value shall be ascertained by determining the gross value of each hereditament or part as if it were a separate house and aggregating the gross values so determined.
11(1)The gross value of a hereditament whose rateable value is by virtue of subsection (1) of section 19 of the [1967 c. 9.] General Rate Act 1967 to be taken to be its net annual value ascertained in accordance with subsections (2) to (4) of that section shall be taken to be its corresponding gross value, that is to say, the gross value which would be equivalent to the net annual value shown in the valuation list if there were deducted any amounts which by virtue of an order made or falling to be treated as made under section 19(2) of the General Rate Act 1967 would be deducted from the gross value of the hereditament if it had been required to be assessed to its gross value instead of its net annual value.
(2)If more than one value is so ascertained to be the corresponding gross value, the highest value so ascertained shall be taken.
12Where after the date on which the control order comes into force—
(a)the valuation list is altered so as to vary the gross value (or where paragraph 11 applies the net annual value) of the house or of the hereditament of which the house forms part, and
(b)the alteration has effect from a date before, or from the same date as, the control order came into force,
compensation is payable as if the value shown in the list on the date when the control order came into force had been that shown in the list as altered.
13(1)The appropriate multiplier for the purposes of this Part of this Schedule is that specified by order of the Secretary of State.
(2)An order under this paragraph shall be made by statutory instrument which shall be subject to annulment in pursuance of a resolution of either House of Parliament.
14(1)If different persons are the dispossessed proprietors of different parts of the house, the compensation payable shall be apportioned between them according to the proportions of the gross value of the house properly attributable to the parts of the house in which they are respectively interested.
(2)If they do not agree on the apportionment they shall refer the matter, in writing, for determination by the district valuer.
