31.1. Where a supply of particular property described in section 99 is made by way of lease, licence or similar arrangement, the rules set out in the second paragraph apply, where the supply is made(1) for a period during which the lessee or any sub-lessee makes, or holds the particular property for the purpose of making one or more supplies described in paragraphs 1 and 2 of section 99; and
(2) for consideration that includes two or more periodic payments that are attributable to successive parts (each of which is referred to in this section and in section 99 as a “lease interval”) of the period for which possession or use of the particular property is provided under the arrangement.
The rules referred to in the first paragraph are as follows:(1) the supplier is deemed to have made, and the lessee is deemed to have received, a separate supply of the particular property for each lease interval; and
(2) the periodic payment that is attributable to a particular lease interval is deemed to be consideration payable in respect of the separate supply of the particular property for the particular lease interval or, where section 31 applies to property that includes the particular property, the portion of the periodic payment that may reasonably be attributed to the particular property.
