Subject to the provisions of this section, any notice for the purposes of this Act shall be in writing, and any notice or other document required or authorised by or under this Act to be given to or served on any person shall be duly given or served if it is delivered to him or left at his proper address or sent to him by post.

Any such notice or other document required or authorised to be served on any person for the purposes of this Act shall be duly served, if that person is an incorporated company or body, if it is served on the clerk or secretary of that company or body.

For the purposes of this section and F2section seven of the M1Interpretation Act 1978, the proper address of any person on whom any such notice or document is to be served shall, in the case of the clerk or secretary of any incorporated company or body, be that of the registered or principal office of such company or body, and in any other case be the last known address of the person in question.

Where any notice or other document is to be given to or served on a person as being the person having any interest in land and it is not practicable after reasonable inquiry to ascertain his name or address, the notice or document may be given or served by addressing it to him by the description of the person having that interest in the land (naming it) and delivering the notice or document to some responsible person on the land or by affixing it, or a copy of it, to some conspicuous object on the land.

Nothing in this section shall require the Commission to give written notice of their intention to issue an authorisation in pursuance of section six of this Act.
