Hate to disagree but
what about 25.9.1
Registers or equivalent summary records of rateable property including rate books, rate cards
Required as State archives
or
25.5.4
Records of notices issued to ratepayers in relation to valuations, rates and charges, rate remissions, classification of land, etc.
Retain minimum of 10 years after the year in which the valuation was made, then destroy
Think the actual question needs clarification.
