Certificate of lawfulness of existing use or development (CLEUD)
This is a formal procedure under section 191 of the Town and Country Planning Act 1990 whereby a local planning authority can, on the application of any person, issue a CLEUD.
A CLEUD will establish that:
An existing use of the buildings or land is lawful.
Any operations that have been carried out in, on, over or under the land are lawful.
Any other matter that constitutes a breach of condition or limitation subject to which planning permission was granted is lawful.
A CLEUD is conclusive as to the matters with which it deals.
