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 (Use Classes) Order 1987 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.
