Subject to subsection (2) of this section, the valuation officer may at any time cause to be made in a valuation list any alteration which is necessary to correct any clerical or arithmetical error therein and the list shall have effect, and be deemed always to have had effect, accordingly.
If the alteration referred to in the foregoing subsection is made in respect of any matter other than totals, the valuation officer shall, before causing the alteration to be made, send notice thereof to the occupier of the hereditament affected and to the rating authority of the rating area, and shall allow fourteen days to elapse during which any person concerned may make representations with respect to the proposed alteration.
The valuation officer may at any time, if so requested by the rating authority, cause a valuation list to be altered by the deletion therefrom of any hereditament which the valuation officer is satisfied has ceased to exist; and section 79(1) of this Act shall apply in relation to the alteration of a valuation list under this subsection as it applies in relation to its alteration under sections 71 to 78 of this Act with the substitution for the reference in the said section 79(1) to any rate current at the date specified therein of a reference to any rate current at the date of the request.
In addition to any alterations in the valuation list required by paragraph 9(4) or 11(9) to (11) of Schedule 4, paragraph 10(6) of Schedule 6 or paragraph 14(6) of Schedule 7 to this Act or by any order under section 35 of this Act or under paragraph 10 of the said Schedule 4 to be made without a proposal, the valuation officer shall without any proposal—
(a) from time to time cause such alterations to be made in the list as may be requisite for deleting from the list any premises which by virtue of section 33(1)(a) of this Act are not liable to be rated;
(b) cause the list to be altered by the deletion therefrom of any property which he is satisfied has, by virtue of section 38(2) of the Local Government Act 1966, ceased to be rateable.
