Apparatus of National Grid in closed streets
22.—(1) Where any street is stopped up under article 10 (permanent stopping up of streets and private means of access), if National Grid has any apparatus in the street or accessed via that street National Grid has the same rights in respect of that apparatus as it enjoyed immediately before the stopping up and the undertaker 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 but nothing in this paragraph affects any right of the undertaker or National Grid to require the removal of that apparatus under paragraph 25 or the power of the undertaker, subject to compliance with this sub-paragraph, to carry out works under paragraph 27.
(2) Notwithstanding the temporary closure or diversion of any highway under the powers of article 11 (temporary prohibition, restriction or regulation of use or alteration or diversion of streets), National Grid 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.
