Removal of apparatus  Facilities and rights for alternative apparatus  110 (2) If the facilities and rights to be afforded by the undertaker and agreed with SGN under sub- paragraph (1) above in respect of any alternative apparatus, and the terms and conditions subject  to which those facilities and rights are to be granted, are less favourable on the whole to SGN than  the facilities and rights enjoyed by it in respect of the apparatus to be decommissioned or removed  then the terms and conditions to which those facilities and rights are subject in the matter are  111. —(1) Where, in accordance with the provisions of this Part of this Schedule, the undertaker  affords to or secures for SGN facilities and rights in land for the access to, construction and  maintenance of alternative apparatus in substitution for apparatus to be decommissioned or  removed, those facilities and rights must be granted upon such terms and conditions as may be  agreed between the undertaker and SGN and must be no less favourable on the whole to SGN than  the facilities and rights enjoyed by it in respect of the apparatus to be decommissioned or removed  unless otherwise agreed by SGN.  (5) SGN must, after the alternative apparatus to be provided or constructed has been agreed, and  subject to the prior grant to SGN of such facilities and rights as are referred to in sub-paragraph  (2) or (3) have been afforded to SGN to its satisfaction, then proceed without unnecessary delay to  construct and bring into operation the alternative apparatus and subsequently to decommission or  remove any apparatus required by the undertaker to be decommissioned or removed under the  provisions of this Part of this Schedule.  (4) Any alternative apparatus to be constructed in land of or land secured by the undertaker  under this Part of this Schedule must be constructed in such manner and in such line or situation as  may be agreed between SGN and the undertaker.  (3) If the undertaker is unable to afford such facilities and rights as are mentioned in sub- paragraph (2), in the land in which the alternative apparatus or part of such apparatus is to be  constructed, SGN may, on receipt of a written notice to that effect from the undertaker, take such  steps as are reasonable in the circumstances in an endeavour to obtain the necessary facilities and  rights in the land in which the alternative apparatus is to be constructed save that this obligation  does not extend to the requirement for SGN to use its compulsory purchase powers to this end  unless it (in its absolute discretion) elects to so do.  (2) If, for the purpose of executing any works in, on, under or over any land purchased, held,  appropriated or used under this Order, the undertaker requires the removal of any apparatus placed  in that land, it must give to SGN advance written notice of that requirement, together with a plan  and section of the work proposed, and of the proposed position of the alternative apparatus to be  provided or constructed and in that case (or if in consequence of the exercise of any of the powers  conferred by this Order SGN reasonably needs to move or remove any of its apparatus) the  undertaker must afford to SGN to its satisfaction (taking into account sub-paragraph 111(1)  below) the necessary facilities and rights—  110. —(1) If, in the exercise of the agreement reached in accordance with paragraph 104 or in  any other authorised manner, the undertaker acquires any interest in any land in which any  apparatus is placed, that apparatus must not be decommissioned or removed under this Part of this  Schedule and any right of SGN to maintain that apparatus in that land must not be extinguished  until alternative apparatus has been constructed, is in operation to the reasonable satisfaction of  SGN and in accordance with sub-paragraph (2) to (5) inclusive.  (a) for the construction of alternative apparatus (including appropriate working areas  required to reasonably and safely undertake necessary works by SGN in respect of the  apparatus);  (b) subsequently for the maintenance of that apparatus (including appropriate working areas  required to reasonably and safely undertake necessary works by SGN in respect of the  apparatus); and  (c) to allow access to that apparatus (including appropriate working areas required to  reasonably and safely undertake necessary works by SGN in respect of the apparatus).
