Making your Lawful Development Certificate appeal (Guide)
Appendix 5

The purpose of the system
Sections 191 and 192 of the Town and Country Planning Act 1990 (the
1990 Act) provide for anyone (not just a person with a legal interest
in the land) to apply to the local planning authority (LPA) for a lawful
development certificate. A certificate is a statutory document certifying:-
(a) in the case of an application under section 191, the lawfulness for
planning purposes, of existing operations on, or use of land, or some
activity being carried out in breach of a planning condition; or
(b) in the case of an application under section 192 the lawfulness of
proposed operations on, or use of land.
A lawful development certificate has no function in determining whether
consent may be required under other legislation such as the Planning (Listed
Buildings and Conservation Areas) Act 1990.
What “lawfulness” means for planning purposes
Uses and operations are “lawful” if no enforcement action
may be taken against them and they are not in contravention of any enforcement
notice which is in force. A failure to comply with any condition or limitation,
subject to which planning permission has been granted, is “lawful”
if the time for taking enforcement action in respect of the failure has
expired and it does not constitute a contravention of any enforcement
notice or breach of condition notice which is in force.
What a certificate does
A certificate granted for an existing use, operation or activity will
specify (by reference to a plan or drawing) the area of land included
in the certificate and describe the precise nature of the use, operation
or activity which is certified as lawful. The certificate will not protect
you from enforcement action by the planning authority if you subsequently
change the specified use ‘materially’ without making a planning
application for it. For example, a certificate may specify that a haulage
contractor’s site can be used lawfully for the parking of a defined
number of heavy goods vehicles, of a specified capacity or size, and specify
the areas of the site which have been used for vehicle maintenance purposes.
Or it may specify the area used for the storage of pallets and the maximum
height to which they are to be stacked. Or it may specify the hours during
which any operations have taken place on the site. If you do something
materially different from that set out in the certificate, the LPA may
be able to take enforcement action against you.
A certificate granted for a proposed use or operation will describe the
precise use or operations on a site in the terms considered permissible
without the need to make a planning application for it.
The certificate will always give reasons why the use, operations or activity
is, or would be, lawful. It will conclusively establish the lawfulness
of the use, operations or activity covered by the certificate. A certificate
granted for an existing use, operation or activity will not protect future
development on the site. For example, an extension to an existing building
described in the certificate, or the intensification of an existing use
will not be covered. A certificate granted for a future use or operation
will protect future development, but only if that future development is
as described in the certificate and is undertaken before there is any
material change in relevant circumstances. If the limitations specified
in a certificate are exceeded, the landowner or occupier may be liable
to enforcement action by the planning authority for any resulting breach
of planning control.
