The Helios Renewable Energy Project Order 2025

• (5) The utility undertaker in question must, after the alternative apparatus to be provided or constructed has been agreed or settled by arbitration in accordance with article 39 (arbitration), and after the grant to the utility 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 undertaker to be removed under the provisions of this Part of this Schedule.

• (6) Regardless of anything in sub-paragraph (5), if the undertaker gives notice in writing to the utility undertaker in question that it desires itself to execute any work, or part of any work, in connection with the construction or removal of apparatus in any land controlled by the undertaker, that work, instead of being executed by the utility undertaker, must be executed by the undertaker without unnecessary delay under the superintendence, if given, and to the reasonable satisfaction of the utility undertaker.

• (7) Nothing in sub-paragraph (6) authorises the undertaker to execute the placing, installation, bedding, packing, removal, connection or disconnection of any apparatus, or execute any filling around the apparatus (where the apparatus is laid in a trench) within 300 millimetres of the apparatus.

Facilities and rights for alternative apparatus

6

• (1) Where, in accordance with the provisions of this part of this Schedule, the undertaker affords to a utility undertaker facilities and rights for the construction and maintenance in land of the undertaker 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 undertaker and the utility undertaker in question or in default of agreement settled by arbitration in accordance with article 39 (arbitration).

• (2) If the facilities and rights to be afforded by the undertaker in respect of any alternative apparatus, and the terms and conditions subject to which those facilities and rights are to be granted, are in the opinion of the arbitrator less favourable on the whole to the utility undertaker in question 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 arbitrator must make such provision for the payment of compensation by the undertaker to that utility undertaker as appears to the arbitrator to be reasonable having regard to all the circumstances of the particular case.

Retained apparatus

7

• (1) Not less than 28 days before starting the execution of any works in, on or under any land purchased, held, appropriated or used under this Order that are near to, or will or may affect, any apparatus the removal of which has not been required by the undertaker under paragraph 5(2), the undertaker must submit to the utility undertaker in question a plan, section and description of the works to be executed.

• (2) Those works must be executed only in accordance with the plan, section and description submitted under sub-paragraph (1) and in accordance with such reasonable requirements as may be made in accordance with sub-paragraph (3) by the utility undertaker for the alteration or otherwise for the protection of the apparatus, or for securing access to it, and the utility undertaker is entitled to watch and inspect the execution of those works.

• (3) Any requirements made by a utility undertaker under sub-paragraph (2) must be made within a period of 21 days beginning with the date on which a plan, section and description under sub-paragraph (1) are submitted to it.

• (4) If a utility undertaker, in accordance with sub-paragraph (3) and in consequence of the works proposed by the undertaker, reasonably requires the removal of any apparatus and gives written notice to the undertaker of that requirement, the provisions of this Part of this Schedule apply as if the removal of the apparatus had been required by the undertaker under paragraph 5(2).

• (5) Nothing in this paragraph precludes the undertaker from submitting at any time or from time to time, but in no case less than 28 days before commencing the execution of any works, a new plan, section and description instead of those previously submitted, and having done so the provisions of this paragraph apply to and in respect of the new plan, section and description.

• (6) The undertaker is not required to comply with sub-paragraph (1) in a case of emergency but in that case it must give to the utility undertaker in question notice as soon as is reasonably practicable as well as a plan, section and description of those works as soon as reasonably practicable subsequently and must comply with sub-paragraph (2) in so far as is reasonably practicable in the circumstances.

Expenses and costs

8

• (1) Subject to the following provisions of this paragraph, the undertaker must repay to a utility undertaker the reasonable expenses agreed with the undertaker in advance and reasonably incurred by that utility undertaker in, or in connection with, the inspection, removal, alteration or protection of any apparatus or the construction of any new apparatus which may be required in consequence of the execution of any such works as are referred to in paragraph 5(2).

• (2) There is to 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, 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,

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 undertaker or, in default of agreement, is not determined by arbitration in accordance with article 39 (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 utility undertaker in question by virtue of sub-paragraph (1) is to be reduced by the amount of that excess.

• (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 where such extension is required in consequence of the execution of any such works as are referred to in paragraph 5(2); 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 a utility undertaker in respect of works by virtue of sub-paragraph (1), 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 the utility undertaker any financial benefit by deferment of the time for renewal of the apparatus in the ordinary course, is to be reduced by the amount which represents that benefit.

9

• (1) Subject to sub-paragraphs (2) and (3), if by reason or in consequence of the construction of any such works referred to in paragraph 5(2) any damage is caused to any 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 a utility undertaker, or there is any interruption in any service provided, or in the supply of any goods, by any utility undertaker, the undertaker must—

• (a) bear and pay the cost reasonably incurred by that utility undertaker in making good such damage or restoring the supply; and

• (b) make reasonable compensation to that utility undertaker for any other expenses, loss, damages, penalty or costs incurred by the utility undertaker,

by reason of or in consequence of any such damage or interruption.

• (2) Nothing in sub-paragraph (1) imposes any liability on the undertaker with respect to—

• (a) any damage or interruption to the extent that it is attributable to the act, neglect or default of a utility undertaker, its officers, servants, contractors or agents; or

• (b) any indirect or consequential loss of the utility undertaker or any third party (including but not limited to loss of use, revenue, profit, contract, production, increased cost of working or business interruption) arising from any such damage or interruption.

• (3) A utility undertaker must give the undertaker reasonable notice of any such claim or demand and no settlement or compromise is to be made without the consent of the undertaker and, if such consent is withheld, the undertaker has the sole conduct of any settlement or compromise or of any proceedings necessary to resist the claim or demand.

On Street Apparatus

41

Except for paragraphs 42 (apparatus of NGT in temporarily closed streets), 47 (retained apparatus: protection), 48 (expenses) and 49 (indemnity) of this Schedule which will apply in respect of the exercise of all or any powers under the Order affecting the rights and apparatus of NGT, the other provisions of this Schedule do not apply to apparatus in respect of which the relations between the undertaker and NGT are regulated by the provisions of Part 3 of the 1991 Act.

Apparatus of NGT in temporarily closed streets

42

• (1) Where any street is closed under article 13 (temporary closure of and permitting vehicular use on public rights of way), if NGT has any apparatus in the street or accessed via that street NGT has the same rights in respect of that apparatus as it enjoyed immediately before the closure and the undertaker must grant to NGT, or procure the granting to NGT of, legal easements reasonably satisfactory to NGT in respect of such apparatus and access to it prior to the closure of any such street or highway but nothing in this paragraph affects any right of the undertaker or NGT to require the removal of that apparatus under paragraph 45 or the power of the undertaker, subject to compliance with this sub-paragraph, to carry out works under paragraph 47.

• (2) Notwithstanding the temporary closure or diversion of any highway under the powers of article 13 (temporary closure of and permitting vehicular use on public rights of way), NGT is at liberty at all times to take all necessary access across any such closed highway and to execute and do all such works and things in, upon or under any such highway as may be reasonably necessary or desirable to enable it to maintain any apparatus which at the time of the closure or diversion was in that highway.

Protective work to buildings

43

The undertaker, in the case of the powers conferred by article 18 (protective work to buildings), must exercise those powers so as not to obstruct or render less convenient the access to any apparatus without the written consent of NGT.

Acquisition of land

44

• (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 undertaker may not (a) appropriate or acquire or take temporary possession of any land or apparatus or (b) appropriate, acquire, extinguish, interfere with or override any easement, other interest or right and/or apparatus of NGT otherwise than by agreement.

• (2) As a condition of an 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 NGT and the undertaker) that is 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 NGT or affect the provisions of any enactment or agreement regulating the relations between NGT and the undertaker in respect of any apparatus laid or erected in land belonging to or secured by the undertaker, the undertaker must as NGT reasonably requires enter into such deeds of consent upon such terms and conditions as may be agreed between NGT and the undertaker acting reasonably and which must be no less favourable on the whole to NGT unless otherwise agreed by NGT, and it will be the responsibility of the undertaker 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 undertaker and NGT 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 NGT and/or other enactments relied upon by NGT as of right or other use in relation to the apparatus, then the provisions in this Schedule shall prevail.

• (4) Any agreement or consent granted by NGT under paragraph 47 or any other paragraph of this Part of this Schedule, shall not be taken to constitute agreement under sub-paragraph (1).

Removal of apparatus

45

• (1) If, in the exercise of the powers conferred by this Order, the undertaker acquires any interest in or possesses temporarily any land in which any apparatus is placed, that apparatus must not be removed under this Part of this Schedule and any right of NGT 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 NGT in accordance with sub-paragraph (2) to (5).

• (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 NGT 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 NGT reasonably needs to remove any of its apparatus) the undertaker must, subject to sub-paragraph (3), secure any necessary consents for the alternative apparatus and afford to NGT to its satisfaction (taking into account paragraph 46(1) below) the necessary facilities and rights—

• (a) for the construction of alternative apparatus in other land of or land secured by the undertaker; 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 undertaker, or 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, NGT must, 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 shall not extend to the requirement for NGT 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 undertaker under this Part of this Schedule must be constructed in such manner and in such line or situation as may be agreed between NGT and the undertaker.

• (5) NGT must, after the alternative apparatus to be provided or constructed has been agreed, and subject to a written diversion agreement having been entered into between the parties and the grant to NGT 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 undertaker to be removed under the provisions of this Part of this Schedule.

Facilities and rights for alternative apparatus

46

• (1) Where, in accordance with the provisions of this Part of this Schedule, the undertaker affords to or secures for NGT 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 undertaker and NGT and must be no less favourable on the whole to NGT than the facilities and rights enjoyed by it in respect of the apparatus to be removed unless otherwise agreed by NGT.

• (2) If the facilities and rights to be afforded by the undertaker 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 NGT 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 may be referred to arbitration in accordance with paragraph 15 (Arbitration) of this Part of this Schedule and the arbitrator must make such provision for the payment of compensation by the undertaker to NGT as appears to the arbitrator to be reasonable having regard to all the circumstances of the particular case.

• (5) NGT must, in respect of any matter covered by the indemnity given by the undertaker in this paragraph, at all times act reasonably and in the same manner as it would as if settling third party claims on its own behalf from its own funds.

• (6) NGT must use its reasonable endeavours to mitigate and to minimise any costs, expenses, loss, demands, and penalties to which the indemnity under this paragraph applies where it is within NGT’s reasonable ability and control to do so and which expressly excludes any obligation to mitigate liability arising from third parties which is outside of NGT’s control and if reasonably requested to do so by the undertaker NGT must provide an explanation of how the claim has been minimised, where relevant.

• (7) Not to commence construction (and not to permit the commencement of such construction) of the authorised works on any land owned by NGT or in respect of which NGT has an easement or wayleave for its apparatus or any other interest or to carry out any works within 15 metres of NGT’s apparatus until the following conditions are satisfied—

• (a) unless and until NGT is satisfied acting reasonably (but subject to all necessary regulatory constraints) that the undertaker 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 NGT has confirmed the same to the undertaker in writing; and

• (b) unless and until NGT is satisfied acting reasonably (but subject to all necessary regulatory constraints) that the undertaker has procured acceptable insurance (and provided evidence to NGT 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 NGT has confirmed the same in writing to the undertaker.

• (8) In the event that the undertaker fails to comply with 49(7) of this Part of this Schedule, nothing in this Part of this Schedule shall prevent NGT from seeking injunctive relief (or any other equitable remedy) in any court of competent jurisdiction.

Enactments and agreements

50

Save to the extent provided for to the contrary elsewhere in this Part of this Schedule or by agreement in writing between NGT and the undertaker, nothing in this Part of this Schedule affects the provisions of any enactment or agreement regulating the relations between the undertaker and NGT in respect of any apparatus laid or erected in land belonging to the undertaker on the date on which this Order is made.

Co-operation

51

• (1) Where in consequence of the proposed construction of any part of the authorised works, the undertaker or NGT requires the removal of apparatus under paragraph 45(2) or NGT makes requirements for the protection or alteration of apparatus under paragraph 47, the undertaker shall use its best endeavours to co-ordinate the execution of the works in the interests of safety and the efficient and economic execution of the authorised works and taking into account the need to ensure the safe and efficient operation of NGT’s undertaking and NGT shall use its best endeavours to co-operate with the undertaker for that purpose.

• (2) For the avoidance of doubt whenever NGT’s consent, agreement or approval is required in relation to plans, documents or other information submitted by the undertaker or the taking of action by the undertaker, it must not be unreasonably withheld or delayed.

Access

52

If in consequence of the agreement reached in accordance with paragraph 44(1) or the powers granted under this Order the access to any apparatus is materially obstructed, the undertaker must provide such alternative means of access to such apparatus as will enable NGT to maintain or use the apparatus no less effectively than was possible before such obstruction.

Arbitration

53

Save for differences or disputes arising under paragraph 45(2), 45(4) 46(1) and 47 any difference or dispute arising between the undertaker and NGT under this Part of this Schedule must, unless otherwise agreed in writing between the undertaker and NGT, be determined by arbitration in accordance with article 39 (arbitration).

Notices
