Where any written demand is given to a tenant of premises to which this Part applies, the demand must contain the following information, namely—
Where—
then (subject to subsection (3)) any part of the amount demanded which consists of a service charge or an administration charge ("the relevant amount") shall be treated for all purposes as not being due from the tenant to the landlord at any time before that information is furnished by the landlord by notice given to the tenant.
The relevant amount shall not be so treated in relation to any time when, by virtue of an order of any court or tribunal, there is in force an appointment of a receiver or manager whose functions include the receiving of service charges or (as the case may be) administration charges from the tenant.
In this section "demand" means a demand for rent or other sums payable to the landlord under the terms of the tenancy.
