Statutory undertakers shall, subject to the following provisions of this Part of this Act, be entitled to compensation from the local planning authority—
Where, by virtue of section 230 of this Act, any right vested in or belonging to statutory undertakers is extinguished, or any requirement is imposed on statutory undertakers, those undertakers shall be entitled to compensation from the acquiring or appropriating authority at whose instance the right was extinguished or the requirement imposed.
Where works are carried out for the removal or re-siting of statutory undertakers' apparatus, being works which the undertakers have the right to carry out by virtue of section 232 of this Act or an order of Ministers thereunder, the undertakers shall be entitled to compensation from the acquiring or appropriating authority.
Notwithstanding anything in subsection (1) of this section, if the decision or order in question relates to land acquired by the statutory undertakers after 7th January 1947, and the Secretary of State and the appropriate Minister are satisfied, having regard to the nature, situation and existing development of the land and of any neighbouring land, and to any other material considerations, that it is unreasonable that compensation should be recovered in respect of that decision or order, they may include therein a direction that subsection (1) of this section shall not apply to that decision or order.
For the purposes of this section the conditions referred to in sections 41 and 42 of this Act shall be disregarded and no compensation shall be payable under this section in respect of the imposition of any condition to which section 71 or 82 of this Act applies.
