This is a contractual provision within
a lease, that specifies the use, or uses to which a
property may be put and the uses which are prohibited.
The formal classification of "Uses"
are set out in the Town and Country Planning Order as
amended, which is a statutory instrument defining various
use classes.
The terminology of a user clause contained
within a lease is critical in determining whether the
use specified is restrictive or open.
This aspect can be very important
when considering the open market rental value of a property.
