Paragraph 2

In the case of a mixed hereditament, “rateable value” means that value as defined in paragraph 1 but less such amount as reflects the proportion which the valuation officer certifies to the charging authority for the purpose of transition to non-domestic rating under the Non-Domestic Rating (Transitional Period) Regulations 1990^f1 as reasonably attributable to non-domestic use or the value which he otherwise notifies for the purposes of these Regulations as reflecting the rateable value of the domestic portion of the hereditament.
