"… since the letting of apartments and the cleaning of the common parts of an apartment block can, in circumstances such as those at issue in the main proceedings, be separated from each other, such letting and such cleaning cannot be regarded as constituting a single transaction 35 within the meaning of the case-law of the Court."
"… the content of a lease may be a factor of importance in assessing whether there is a single supply. In the main proceedings, it appears that the economic reason for concluding the lease is not only to obtain the right to occupy the premises concerned, but also for the tenant to 25 obtain a number of services. The lease accordingly designates a single supply agreed between the landlord and the tenant. Moreover, it should be observed that the leasing of immovable property and the supply of associated services … may objectively constitute such a supply. Obtaining the services concerned cannot be regarded as 30 constituting an end in itself for an average tenant of premises such as those at issue in the main proceedings, but constitutes rather a means of better enjoying the principal supply, namely the leasing of commercial premises."
"However, that does not mean that those supplies of services, which are linked to the leasing of immovable property and are supplied in 40 accordance with the provisions of a lease, cannot constitute ancillary supplies or be indivisible from that leasing."
"25. … even though in the circumstances of the main proceedings the inclusion of services in the lease in question supports the view that there is a single supply, it must be noted that the mere fact that a supply is included in a lease cannot in itself 5 constitute the decisive element to that effect. Thus if a lease were to provide for the inclusion of supplies which by their nature could not objectively be regarded as indivisible from or ancillary to the principal supply of the leasing of immovable property, but were independent of it, such supplies having 10 only an artificial link to the principal supply, those supplies would not form part of a single supply of the leasing of immovable property, exempt from VAT. In the dispute in the main proceedings … the obtaining of the services in question does not, however, appear to constitute an end in itself for the tenant. 15 26. As to the relevance of the fact that a third party could in principle supply certain services, it must be observed that the existence of such a possibility is not decisive in itself either. As may be seen from the Court’s case-law, the possibility that elements of a single supply may, in other circumstances, be supplied separately is inherent in the 20 concept of a single composite transaction …"
