on a day before 1st April 2026 a hereditament (“new hereditament”) comes into existence by virtue of—
property previously rated as a single hereditament becoming liable to be rated in parts;
property previously rated in parts becoming liable to be rated as a single hereditament; or
a hereditament or any part of a hereditament becoming part of a different hereditament; and

as if the new hereditament was shown in a list for that day;

where the improvement relief provisions would have applied for 31st March 2026 had the new hereditament been shown in the list for that day, as if the value of A for that day was the amount found by applying the formula—
