Paragraph 2

In the case of a hereditament which, if local non-domestic rating lists under Part III of the Act (non-domestic rating) had been in force on 31st March 1990, would have been shown in such a list as a composite hereditament on that day^f1, “rateable value” means that value as defined in paragraph 1 but less such amount as reflects the proportion certified by the valuation officer to the charging authority for the purposes of transition to non-domestic rating under the Non-Domestic Rating (Transitional Period) Regulations 1990^f2 as reasonably attributable to non-domestic use.
