(b)for the relevant year beginning on 1st April 2024, X is 140; and
(c)for the relevant year beginning on 1st April 2025, X is 155.
(3) Paragraph (4) applies where the notional chargeable amount for the hereditament for the relevant year exceeds the base liability for the hereditament for the year, and—

(b)the hereditament is shown in the central list or in a local list outside Greater London and the rateable value shown in that list for that hereditament for 1st April 2023 is more than £20,000 and less than or equal to £100,000.
(4) For the purposes of this regulation, for a hereditament mentioned in paragraph (3)—
