Any document required or authorised by this Act to be given to or served on any person may be given or served either by delivering it to that person, or by leaving it at his proper address, or by post by means of the recorded delivery service.

Any such document required or authorised to be given to or served on an authority or body being a corporation shall be duly given or served if it is given to or served on the secretary or clerk of the authority or body.

For the purposes of this section and of section 26 of the Interpretation Act 1889 in its application to this section, the proper address of any person to or on whom any such document as aforesaid is to be given or served shall, in the case of the secretary or clerk of a corporation, be that of the registered or principal office of the corporation, and in any other case be the last-known address of the person to be served, subject, however, to this qualification, that, where the person to or on whom the document is to be given or served has, in accordance with arrangements agreed, furnished an address for the giving or service of the document, being an address in the United Kingdom, his proper address for the purposes aforesaid shall be the address furnished.

If the name or the address of any owner, lessee or occupier of land to or on whom any such document as aforesaid is to be given or served cannot after reasonable inquiry be ascertained by the authority, body or person seeking to give or serve the document, the document may be given or served by addressing it to the person to or on whom it is to be given or served by the description of " owner", " lessee" or " occupier " of the land (describing it) to which the document relates, and by delivering it to some responsible person resident or appearing to be resident on the premises, or, if there is no such person to whom it can be delivered, by affixing it, or a copy of it, to some conspicuous part of the premises.
