“(1C) Where – (a) a person (‘the relevant person’) carries out a residential conversion by arranging for any of the work of the conversion to be done by another (the Contractor). (b) the relevant person’s carrying out of the works is lawful and otherwise than in the course or furtherance of any business, (c) the contractor is not acting as an architect, surveyor or consultant or a supervisory capacity, and (d) VAT is chargeable on services consisting in the work done by the contractor, the Commissioners shall, on a claim made in that behalf, refund to the relevant person the amount of VAT so chargeable. (1D) For the purposes of this section works constitute a residential conversion to the extent that they consist in the conversion of a non-residential building, or a non-residential part of a building, into – (a) a building designed as a dwelling or a number of dwellings; … (b) a building intended for use solely for a relevant residential purpose; or (c) anything which would fall within paragraph (a) or (b) above if different parts of a building were treated as separate buildings. (4) the Notes to Group 5 of Schedule 8 shall apply for construing this section as they apply for construing that Group but this is subject to subsection (4A) below. (4A) the meaning of non-residential given by Note (7A) of Group 5 of Schedule 8 (and not that given by Note (7) of that Group) applies for the purposes of this section but as if- (a) references in that Note to item 3 of that Group were references to this section and (b) Paragraph (b) (iii) of that Note were omitted. Schedule 8, Group5, states: NOTES (7A) “For the purposes of item 3, and for the purposes of these Notes so far as having effect for the purposes of item 3, a building or part of a building is “non-residential” if – (a) it is neither designed, nor adapted, for use … as a dwelling or number of dwellings …” (b) It is designed, or adapted for such use but- (i) it was constructed more than 10 years before the commencement of the works of conversion and (ii) no part of it has in the period of 10 years immediately preceding the commencement of those works been used as a dwelling ………., and (iii) no part of it is being so used. (8) References to a non-residential building or a non-residential part of a building do not include a reference to a garage occupied together with a dwelling. (9) The conversion ……….of a non residential part of a building which already contains a residential part is not included within items 1(b) or 3 unless the result of that conversion is to create an additional dwelling or dwellings. (16) For the purpose of this Group, the construction of the building does not include- (a) the conversion reconstruction or alteration of an existing building; or (b) any enlargement of or extension to an existing building except to the extent the enlargement or extension creates an additional dwelling or dwellings; or (c) ……… the construction of an annex to an existing building.”
‘…even if only part of the building is non- residential it is not necessary that the non-residential part must itself be converted into a dwelling. It is sufficient for this purpose (but subject to note (9) …) , if the building comprised a non-residential part which was the subject of the conversion works, that after conversion the building (taken as a whole, including both the residential and non-residential parts) was a building designed as a dwelling. This was the part of the judgment of Peter Smith, J. in … Blom Cooper, which was not pursued on appeal to the Court of Appeal in that case: see[2003] STC 669 per Chadwick LJ at [17]. It was also confirmed in … Jacobs; see per Ward LJ at [34].’
