Section 125 | Dwellings produced from other dwellings

(1)This section applies where an existing building that is a dwelling or dwellings (“the old dwelling” or “the old dwellings”) becomes a different dwelling or dwellings ( “ new ” dwellings) as a result of structural alteration.

(2)Any question as to whether or not a person has a single-dwelling interest at any time either in the old dwelling or dwellings or in a new dwelling is determined on the assumption that the old dwelling or dwellings cease to exist, and any new dwelling come into existence, only when the conversion is completed.

(3)The day after the conversion is completed is a valuation date in the case of any single-dwelling interest in a new dwelling.

(4)References to when the conversion is completed are to the end of the day on which the new dwelling is treated as having come into existence (or the first day on which all the new dwellings are treated as having come into existence) for the purposes of—

(a)Part 1 of the Local Government Finance Act 1992 (council tax: England and Wales) (see section 17 of that Act), or

(b)Part 2 of that Act (council tax: Scotland) (see section 83 of that Act), or

(c)the Rates (Northern Ireland) Order 1977 (S.I. 1977/2157 (N.I. 28)) (see Article 25B of that Order).
