6 Acquisition of land
(1) Regardless of any provision in this Order or anything shown on the land plans or contained in the book of reference to the Order, the promoter may not acquire any land interest or apparatus or override any easement and/or other interest of the undertaker otherwise than by agreement.
(2) As a condition of agreement between the parties in sub-paragraph (1), prior to the carrying out of any part of the authorised works (or in such other timeframe as may be agreed between the undertaker and the promoter) that are subject to the requirements of this Part of this Schedule that will cause any conflict with or breach the terms of any easement and/or other legal or land interest of the undertaker and/or affects the provisions of any enactment or agreement regulating the relations between the undertaker and the promoter in respect of any apparatus laid or erected in land belonging to or secured by the promoter, the promoter must as the undertaker reasonably requires enter into such deeds of consent upon such terms and conditions as may be agreed between the undertaker and the promoter acting reasonably and which must be no less favourable on the whole to the undertaker unless otherwise agreed by the undertaker, and it will be the responsibility of the promoter to procure and/or secure the consent and entering into of such deeds and variations by all other third parties with an interest in the land at that time who are affected by such authorised works.
(3) The promoter and the undertaker agree that where there is any inconsistency or duplication between the provisions set out in this Part of this Schedule relating to the relocation and/or removal of apparatus including but not limited to the payment of costs and expenses relating to such relocation and/or removal of apparatus) and the provisions of any existing easement, rights, agreements and licences granted, used, enjoyed or exercised by the undertaker and/or other enactments relied upon by the undertaker as of right or other use in relation to the apparatus, then the provisions in this Part of this Schedule shall prevail.
(4) Any agreement or consent granted by the undertaker under paragraphs 9 or 10 or any other paragraph of this Part of this Schedule shall not be taken to constitute agreement under paragraph 6.

7 Removal of apparatus
(1) If, in the exercise of the agreement reached in accordance with paragraph 6 or in any other authorised manner, the promoter acquires any interest in any land in which any apparatus is placed, that apparatus must not be removed under this Part of this Schedule and any right of an undertaker to maintain that apparatus in that land must not be extinguished until alternative apparatus has been constructed, and is in operation to the reasonable satisfaction of the undertaker in question in accordance with sub-paragraphs (2) to (5) inclusive.
(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 promoter requires the removal of any apparatus placed in that land, it must give to the undertaker 56 days’ advance written notice of that requirement, together with a plan 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 the undertaker reasonably needs to remove any of its apparatus) the promoter must, subject to sub-paragraph (3), afford to the undertaker to its satisfaction (taking into account paragraph 8(1) below) the necessary facilities and rights—
(a) for the construction of alternative apparatus in other land of or land secured by the promoter; and
(b) subsequently for the maintenance of that apparatus.
(3) If alternative apparatus or any part of such apparatus is to be constructed elsewhere than in other land of or land secured by the promoter, or the promoter 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, the undertaker must, on receipt of a written notice to that effect from the promoter, 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 shall not extend to the requirement for the undertaker to use its compulsory purchase powers to this end unless it elects to so do.
(4) Any alternative apparatus to be constructed in land of or land secured by the promoter under this Part of this Schedule must be constructed in such manner and in such line or situation as may be agreed between the undertaker and the promoter.
(5) The undertaker must, after the alternative apparatus to be provided or constructed has been agreed, and subject to the grant to the undertaker of any such facilities and rights as are referred to in sub-paragraph (2) or (3), proceed without unnecessary delay to construct and bring into operation the alternative apparatus and subsequently to remove any apparatus required by the promoter to be removed under the provisions of this Part of this Schedule.

8 Facilities and rights for alternative apparatus
(1) Where, in accordance with the provisions of this Part of this Schedule, the promoter affords to or secures for the undertaker facilities and rights in land for the construction, use, maintenance and protection of alternative apparatus in substitution for apparatus to be removed, those facilities and rights must be granted upon such terms and conditions as may be agreed between the promoter and the undertaker and must be no less favourable on the whole to the undertaker than the facilities and rights enjoyed by it in respect of the apparatus to be removed unless otherwise agreed by the undertaker.
(2) If the facilities and rights to be afforded by the promoter and agreed with the undertaker 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 the undertaker than the facilities and rights enjoyed by it in respect of the apparatus to be removed and the terms and conditions to which those facilities and rights are subject in the matter will be referred to arbitration in accordance with paragraph 16 (arbitration) of this Part of this Schedule and the arbitrator shall make such provision for the payment of compensation by the promoter to the undertaker as appears to the arbitrator to be reasonable having regard to all the circumstances of the particular case.

(f) the survey of any land, apparatus or works, the inspection and monitoring of works or the installation or removal of any temporary works reasonably necessary in consequence of the execution of any such works referred to in this Part of this Schedule.
(2) There will be deducted from any sum payable under sub-paragraph (1) the value of any apparatus removed under the provisions of this Part of this Schedule and which is not re-used as part of the alternative apparatus, that value being calculated after removal.
(3) If in accordance with the provisions of this Part of this Schedule—
(a) apparatus of better type, of greater capacity or of greater dimensions is placed in substitution for existing apparatus of worse type, of smaller capacity or of smaller dimensions; or
(b) apparatus (whether existing apparatus or apparatus substituted for existing apparatus) is placed at a depth greater than the depth at which the existing apparatus was situated,
and the placing of apparatus of that type or capacity or of those dimensions or the placing of apparatus at that depth, as the case may be, is not agreed by the promoter or, in default of agreement, is not determined by arbitration in accordance with article 40 (arbitration) to be necessary, then, if such placing involves cost in the construction of works under this Part of this Schedule exceeding that which would have been involved if the apparatus placed had been of the existing type, capacity or dimensions, or at the existing depth, as the case may be, the amount which apart from this sub-paragraph would be payable to the undertaker by virtue of sub-paragraph (1) will be reduced by the amount of that excess save where it is not possible in the circumstances to obtain the existing type of apparatus at the same capacity and dimensions or place at the existing depth in which case full costs will be borne by the promoter.

(2) The fact that any act or thing may have been done by the undertaker on behalf of the promoter or in accordance with a plan approved by the undertaker or in accordance with any requirement of the undertaker or under its supervision will not (unless sub-paragraph (3) applies), excuse the promoter from liability under the provisions of this sub-paragraph (1) unless the undertaker fails to carry out and execute the works properly with due care and attention and in a skilful and workman like manner or in a manner that does not accord with the approved plan.
(3) Nothing in sub-paragraph (1) shall impose any liability on the promoter in respect of—
(a) any damage or interruption to the extent that it is attributable to the neglect or default of the undertaker, its officers, servants, contractors or agents; and
(b) any authorised works and/or any other works authorised by this Part of this Schedule carried out by the undertaker as an assignee, transferee or lessee of the undertaker with the benefit of the Order pursuant to section 156 of the Planning Act 2008 or article 7 (consent to transfer benefit of Order) subject to the proviso that once such works become apparatus (“new apparatus”), any authorised works yet to be executed and not falling within this sub-section 3(b) will be subject to the full terms of this Part of this Schedule including this paragraph 12.
(4) The undertaker must give the promoter reasonable notice of any such third party claim or demand and no settlement or compromise must, unless payment is required in connection with a statutory compensation scheme, be made without first consulting the promoter and considering their representations.

(a) unless and until the undertaker is satisfied acting reasonably (but subject to all necessary regulatory constraints) that the promoter has first provided the acceptable security (and provided evidence that it shall maintain such acceptable security for the construction period of the authorised works from the proposed date of commencement of construction of the authorised works) and the undertaker has confirmed the same to the promoter in writing; and
(b) unless and until the undertaker is satisfied acting reasonably (but subject to all necessary regulatory constraints) that the promoter has procured acceptable insurance (and provided evidence to the undertaker that it shall maintain such acceptable insurance for the construction period of the authorised works from the proposed date of commencement of construction of the authorised works) and undertaker has confirmed the same in writing to the promoter.
(6) In the event that the promoter fails to comply sub-section (5) nothing in this Part of this Schedule shall prevent the undertaker from seeking injunctive relief (or any other equitable remedy) in any court of competent jurisdiction.

13 Enactments and agreements
