Where any street is stopped up under article 11 (stopping up of streets and extinguishment of rights), any specified undertaker whose apparatus is in the street shall have the same powers and rights in respect of that apparatus as it enjoyed immediately before the stopping up and the promoter will grant to the specified undertaker legal easements reasonably satisfactory to the specified undertaker in respect of such apparatus and access to it, but nothing in this paragraph shall affect any right of the promoter or of the specified undertaker to require the removal of that apparatus under paragraph 8 or the power of the promoter to carry out works under paragraphs 20 to 29.

The promoter shall give not less than 28 days' notice in writing of its intention to stop up any street under article 11 to any specified undertaker whose apparatus is in that street.
