In accordance with this Part the valuation officer for a charging authority shall compile, and then maintain, lists for the authority (to be called its local non-domestic rating lists).

A list must be compiled on 1 April 1990 and on 1 April in every fifth year afterwards.

A list shall come into force on the day on which it is compiled and shall remain in force until the next one is compiled five years later.

Before a list is compiled the valuation officer must take such steps as are reasonably practicable to ensure that it is accurately compiled on 1 April concerned.

Not later than 31 December preceding a day on which a list is to be compiled the valuation officer shall send to the authority a copy of the list he proposes (on the information then before him) to compile.

As soon as is reasonably practicable after receiving the copy the authority shall deposit it at its principal office and take such steps as it thinks most suitable for giving notice of it.

A list must be maintained for so long as is necessary for the purposes of this Part, so that the expiry of the five year period for which it is in force does not detract from the duty to maintain it.

In compiling and maintaining the list which must be compiled on 1 April 1990, the valuation officer may take into account information obtained under section 82 or 86 of the 1967 Act.
