PART III
Ascertainment of total housing valuation for the relevant financial year
6For the purposes of this Schedule a local authority's total housing valuation for any relevant financial year shall be ascertained in accordance with this Part of this Schedule.
7There shall be ascertained—
(a)the aggregate of the gross annual values of all the houses to which the local authority's housing revenue account related at the end of the relevant financial year, and
(b)the aggregate of the gross annual values of all the houses to which the local authority's housing revenue account related at the end of the financial year immediately preceding the relevant financial year:
Provided that in ascertaining the said aggregates there shall be excluded such part of the gross annual value of any house as may be certified by the assessor to be attributable to any garage provided otherwise than by the local authority.
8The amounts ascertained under paragraph 7 of this Schedule shall be added together and their sum shall be divided by two; and the result shall be the local authority's total housing valuation for the relevant financial year.
9Where, by reason of a change in the areas of local authorities, houses are transferred from one local authority to another local authority, the Secretary of State may, having regard to the gross annual values of the houses and the date and circumstances of their transfer, direct that such other method of calculation as he may consider appropriate shall be used for the purposes of this Part of this Schedule in lieu of the method of calculation specified in the two last foregoing paragraphs.
10Any reference in this Part of this Schedule to the gross annual value of a house to which a local authority's housing revenue account related at the end of any financial year shall be construed as a reference to the gross annual value of that house, determined under section 6 of the [1956 c. 60.] Valuation and Rating (Scotland) Act 1956, as shown in the valuation roll in operation on the first day of the financial year immediately following the financial year in question ; so however that if no gross annual value determined as aforesaid is shown for that house in that valuation roll the reference shall be construed as a reference to such value as may be estimated by the assessor to be the gross annual value, determined as aforesaid, of the house.
11References in this Part of this Schedule to the assessor, in relation to any house, are references to the assessor appointed under section 1 of the Valuation and Rating (Scotland) Act 1956, for the area in which the house is situated.
