Subject to the provisions of this Act, this Part of this Act applies to any tenancy where the property comprised in the tenancy is or includes premises which are occupied by the tenant and are so occupied for the purposes of a business carried on by him or for those and other purposes.
Occupation or the carrying on of a business—
shall be treated for the purposes of this section as equivalent to occupation or, as the case may be, the carrying on of a business by the tenant.
Accordingly references (however expressed) in this Part of this Act to the business of, or to use, occupation or enjoyment by, the tenant shall be construed as including references to the business of, or to use, occupation or enjoyment by, a company falling within subsection (1A)(a) above or a person falling within subsection (1A)(b) above.
In this Part of this Act the expression “business” includes a trade, profession or employment and includes any activity carried on by a body of persons, whether corporate or unincorporate.
In the following provisions of this Part of this Act the expression “the holding”, in relation to a tenancy to which this Part of this Act applies, means the property comprised in the tenancy, there being excluded any part thereof which is occupied neither by the tenant nor by a person employed by the tenant and so employed for the purposes of a business by reason of which the tenancy is one to which this Part of this Act applies.
Where the tenant's breach of a prohibition (however expressed) of use for business purposes which subsists under the terms of the tenancy and extends to the whole of that property consists solely of carrying on a home business, this Part of this Act does not apply to the tenancy, even if the immediate landlord or the immediate landlord's predecessor in title has consented to the breach or the immediate landlord has acquiesced in the breach.
In subsection (5) “ home business ” has the same meaning as in section 43ZA.
