Where any public right of way is stopped up under article 11 (closure and diversion of public rights of way and access land), if National Grid has any apparatus in the street or accessed via that street National Grid must be entitled to the same rights in respect of such apparatus as it enjoyed immediately before the closure and the undertaker must grant to National Grid, or must 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 closure of any such street or highway but nothing in this paragraph affects any right of the undertaker or National Grid to require the removal of that apparatus under paragraph 7 or the power of the undertaker, subject to compliance with this sub-paragraph, to carry out works under paragraph 9.

Notwithstanding the temporary closure under the powers of article 11 (closure and diversion of public rights of way and access land), National Grid must be at liberty at all times to take all necessary access across any such street and/or 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 closure or diversion was in that street.
