Subject to subsection (3) below, no express or implied term of any tenancy is to be regarded—
as excluding or restricting the exercise by the tenant of any right to give—
a measured charges notice under section 144A above, or
any consent for the purposes of section 144B(2)(a)(ii) above,
as preventing the installation or connection, in pursuance of such a notice or consent given by the tenant, of a meter for use in determining the charges which may be fixed in relation to water supplied to the premises comprised in the tenancy, or
as requiring any consent to be obtained in relation to such installation or connection.
In subsection (1) above "tenancy" includes a licence which is treated as a tenancy by virtue of section 79(3) of the Housing Act 1985; and references to a "tenant" are to be construed accordingly.
Subsection (1) above does not apply where the tenancy is a fixed term tenancy for a term of less than six months; and for this purpose "fixed term tenancy" means any tenancy other than a periodic tenancy.
