18. This Part of this Schedule does not apply to apparatus in respect of which the relations between TfL and National Grid are regulated by the provisions of Part 3 of the 1991 Act.E+W+S
19.—(1) Without limitation on the scope of any other protection afforded to National Grid elsewhere in the Order, where any street is stopped up under article 9 (permanent stopping up of streets), if National Grid has any apparatus in the street or accessed via that street National Grid is entitled to the same rights in respect of such apparatus as it enjoyed immediately before the stopping up and TfL must grant to National Grid, or procure the granting to National Grid of, legal easements reasonably satisfactory to National Grid in respect of such apparatus and access to it prior to the stopping up of any such street or highway.
(2) Regardless of the temporary stopping up, alteration or diversion of any street under the powers of article 10 (temporary stopping up and restriction of use of streets), National Grid is at liberty at all times to take all necessary access across any stopped up, altered or diverted street and to execute and do all such works and things in, upon or under any such street as may be reasonably necessary or desirable to enable it to maintain any apparatus which at the time of the stopping up, alteration or diversion was in that street.
20.—(1) This Order does not authorise the acquisition or extinguishment of land or rights in land or override any interest in land owned by National Grid that is required for the retention or maintenance of any retained apparatus except with National Grid's agreement (such agreement not to be unreasonably withheld or delayed).
(2) As a condition of agreement between the parties in sub-paragraph (1), prior to the carrying out of any part of the authorised development (or in such other timeframe as may be agreed between National Grid and TfL) 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 or other legal or land interest of National Grid or affects the provisions of any enactment or agreement regulating the relations between National Grid and TfL in respect of any apparatus laid or erected in land belonging to or secured by TfL, TfL must as National Grid reasonably requires enter into such deeds of easement or consent upon such terms and conditions as may be agreed between National Grid and TfL acting reasonably and which must be no less favourable on the whole to National Grid unless otherwise agreed by National Grid, and it is the responsibility of TfL to procure 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 development.
(3) Where there is any inconsistency or duplication between the provisions set out in this Part of this Schedule relating to the relocation or removal of apparatus (including but not limited to the payment of costs and expenses relating to such relocation or removal of apparatus) and the provisions of any existing easement, rights, agreements and licences granted, used, enjoyed or exercised by National Grid or other enactments relied upon by National Grid as of right or other use in relation to the apparatus, then the provisions in this Part of this Schedule prevail.
(4) No agreement or consent granted by National Grid under any other provision of this Part of this Schedule constitutes agreement under sub-paragraph (1).
21.—(1) If, in the exercise of the agreement reached in accordance with paragraph 20 or in any other authorised manner, TfL 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 National Grid 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 National Grid in accordance with sub-paragraphs (2) to (5) inclusive.
(2) If, for the purpose of executing any works comprised in the authorised development in, on, under or over any land purchased, held, appropriated or used under this Order, TfL requires the removal of any apparatus placed in that land, it must give to National Grid 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 National Grid reasonably needs to remove any of its apparatus) TfL must, subject to sub-paragraph (3), afford to National Grid to their satisfaction (taking into account paragraph 22(1)) the necessary facilities and rights for—
(a)the construction of alternative apparatus in other land of, or land secured by, TfL; 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, TfL, or TfL 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, National Grid must, on receipt of a written notice to that effect from TfL, 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 National Grid 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, TfL under this Part of this Schedule must be constructed in such manner and in such line or situation as may be agreed between National Grid and TfL.
(5) National Grid must, after the alternative apparatus to be provided or constructed has been agreed, and subject to the grant to National Grid 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 TfL to be removed under the provisions of this Part of this Schedule.
(6) Where there is any inconsistency or duplication between the provisions set out in this Part of this Schedule relating to the relocation or removal of apparatus (including but not limited to the payment of costs and expenses relating to such relocation or removal of apparatus) and the provisions of any existing easement, rights, agreements and licences granted, used, enjoyed or exercised by National Grid as of right or other use in relation to the apparatus then the provisions in this Part of this Schedule prevail.
22.—(1) Where, in accordance with the provisions of this Part of this Schedule, TfL affords to National Grid facilities and rights for the construction and maintenance and protection in land of TfL 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 TfL and National Grid and must be no less favourable on the whole to National Grid than the facilities and rights enjoyed by it in respect of the apparatus to be removed unless agreed by National Grid.
(2) If the facilities and rights to be afforded by TfL and agreed with National Grid 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 National Grid 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, the matter must be referred to arbitration and the arbitrator must make such provision for the payment of compensation by TfL to National Grid as appears to the arbitrator to be reasonable having regard to all the circumstances of the particular case.
23.—(1) Not less than 56 days before the commencement of any works authorised by this Order that are near to, or will or may affect, any apparatus the removal of which has not been required by TfL under paragraph 21(2) or otherwise, TfL must submit to National Grid a plan.

(8) Where National Grid require any protective works to be carried out either by themselves or by TfL (whether of a temporary or permanent nature) such protective works must be carried out to National Grid's satisfaction prior to the commencement of works requiring the submission of a plan under sub-paragraph (1) and National Grid must give 56 days' notice of such works from the date of submission of the plan (except in an emergency).
(9) If National Grid in accordance with sub-paragraph (6) or (8) and in consequence of the works proposed by TfL, reasonably requires the removal of any apparatus and gives written notice to TfL of that requirement, paragraphs 16 to 18 and 21 to 22 apply as if the removal of the apparatus had been required by TfL under paragraph 21(2).
(10) Nothing in this paragraph precludes TfL from submitting at any time or from time to time, but in no case less than 56 days before commencing the execution of any works, a new plan, instead of the plan previously submitted, and having done so the provisions of this paragraph apply to and in respect of the new plan.
(11) TfL is not required to comply with sub-paragraph (1) where it needs to carry out emergency works as defined in the 1991 Act but in that case it must give to National Grid notice as soon as is reasonably practicable a plan of those works and must—
(a)comply with sub-paragraph (6), (7) and (8) insofar as is reasonably practicable in the circumstances; and
(b)comply with sub-paragraph (12) at all times.
(12) At all times when carrying out any specified works TfL must comply with National Grid's policies for development near or over headlines enshrined in ENA TA 43-8 and the Health and Safety Executive's guidance note 6 “Avoidance of Danger from Overhead Lines”.
(13) As soon as reasonably practicable after any ground subsidence event, TfL must implement an appropriate ground mitigation scheme.
25. TfL must not exercise the powers conferred by article 15 (protective work to buildings), so as to obstruct or render less convenient the access to any apparatus without the written consent of National Grid.
26.—(1) Subject to the following provisions of this paragraph, TfL must repay to National Grid on demand all charges, costs and expenses reasonably incurred or in the case of sub-paragraph (a) compensation properly paid by National Grid in, or in connection with, the inspection, removal, relaying or replacing, alteration or protection of any apparatus or the construction of any new or alternative apparatus which may be required in consequence of the execution of any such works as are referred to in this Part of this Schedule including without limitation—
(a)in connection with the acquisition of rights or the exercise of statutory powers for such apparatus including without limitation in the event that National Grid elects to use compulsory purchase powers to acquire any necessary rights under paragraph 21 sub-paragraph (3) all costs incurred as a result of such action;
(b)carrying out any diversion work or providing alternative apparatus;
(c)cutting off any apparatus from any other apparatus or making safe redundant apparatus;
(d)the approval of plans;
(e)the carrying out of protective works, plus a capitalised sum to cover the cost of maintaining and renewing permanent protective works;
(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 must 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 TfL or in default of agreement settled by arbitration in accordance with article 68 (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 National Grid by virtue of sub-paragraph (1) must be reduced by the amount of that excess except where it is not possible in the circumstances to obtain the existing type of operations, capacity, dimensions or place at the existing depth in which case the full costs must be borne by TfL.
(4) For the purposes of sub-paragraph (3)—
(a)an extension of apparatus to a length greater than the length of existing apparatus must not be treated as a placing of apparatus of greater dimensions than those of the existing apparatus; and
(b)where the provision of a joint in a pipe or cable is agreed, or is determined to be necessary, the consequential provision of a jointing chamber or of a manhole must be treated as if it also had been agreed or had been so determined.
(5) An amount which apart from this sub-paragraph would be payable to National Grid in respect of works by virtue of sub-paragraph (1) must, if the works include the placing of apparatus provided in substitution for apparatus placed more than 7 years and 6 months earlier so as to confer on National Grid any financial benefit by deferment of the time for renewal of the apparatus in the ordinary course, be reduced by the amount which represents that benefit.
27.—(1) Subject to sub-paragraphs (2) and (3), if by reason or in consequence of the construction of any works authorised by this Part of this Schedule or in consequence of the construction, use, maintenance or failure of any of the authorised development by or on behalf of TfL or in consequence of any act or default of TfL (or any person employed or authorised by him) in the course of carrying out such works (including without limitation works carried out by TfL under this Part of this Schedule or any subsidence resulting from any of these works), any material damage is caused to any apparatus or alternative apparatus (other than apparatus the repair of which is not reasonably necessary in view of its intended removal for the purposes of those works) or property of National Grid, or there is any interruption in any service provided, or in the supply of any goods, by National Grid, or National Grid becomes liable to pay any amount to any third party, TfL must—
(a)bear and pay on demand the cost reasonably incurred by National Grid in making good such damage or restoring the supply; and
(b)indemnify National Grid for any other expenses, loss, demands, proceedings, damages, claims, penalty or costs incurred by or recovered from National Grid, by reason or in consequence of any such damage or interruption or National Grid becoming liable to any third party.
(2) The fact that any act or thing may have been done by National Grid on behalf of TfL or in accordance with a plan approved by National Grid or in accordance with any requirement of National Grid as a consequence of the authorised development or under its supervision does not (unless sub-paragraph (3) applies) excuse TfL from liability under the provisions of sub-paragraph (1) unless National Grid fails to carry out and execute the works properly with due care and attention and in a skilful and professional manner or in a manner that does not materially accord with the approved plan or as otherwise agreed between TfL and National Grid.
(3) Nothing in sub-paragraph (1) imposes any liability on TfL in respect of—
(a)any damage or interruption to the extent that it is attributable to the neglect or default of National Grid, its officers, servants, contractors or agents; and
(b)any authorised development or works authorised by this Part of this Schedule carried out by National Grid as an assignee, transferee or lessee of TfL with the benefit of this Order pursuant to section 156 (benefit of order granting development consent) of the 2008 Act or under article 59 (transfer of benefit of order, etc.) of this Order subject to the proviso that once such works become apparatus (“new apparatus”), any works yet to be executed and not falling within this sub-paragraph are subject to the full terms of this Part of this Schedule including this paragraph 27 in respect of such new apparatus.
(4) National Grid must give TfL reasonable notice of any such claim or demand and no settlement or compromise is to be made without National Grid first consulting TfL and considering their representations.
(5) National Grid must use its reasonable endeavours to mitigate in whole or in part and to minimise any costs, expenses, loss, demands, and penalties to which the indemnity under this paragraph 27 applies. If requested to do so by TfL, National Grid must provide an explanation of how the claim has been minimised. TfL is only liable under this paragraph 27 for claims reasonably incurred by National Grid.
28. Save to the extent provided for to the contrary elsewhere in this Part of this Schedule or by agreement in writing between National Grid and TfL, nothing in this Part of this Schedule affects the provisions of any enactment or agreement regulating the relations between TfL and National Grid in respect of any apparatus laid or erected in land belonging to TfL on the date on which this Order is made.
29. National Grid and TfL must use their best endeavours to co-ordinate with each other on the timing and method of execution of any works carried out under this Order or this Part of this Schedule in the interests of safety and the efficient and economic execution of the authorised development and taking into account the need to ensure the safe and efficient operation of the other party's operations.
30. If in consequence of the agreement reached in accordance with paragraph 20 or the powers granted under this Order the access to any apparatus is materially obstructed, TfL must provide such alternative means of access to such apparatus as will enable National Grid to maintain or use the apparatus no less effectively than was possible before such obstruction.
31. Any difference or dispute arising between TfL and National Grid under this Part of this Schedule must, unless otherwise agreed in writing between TfL and National Grid, be determined by arbitration in accordance with article 68 (arbitration).
