The Town and Country Planning (Use Classes) Order 1987 (the "UCO 1987") is a Statutory Instrument, applying in England and Wales, that specifies various "Use Classes" for which planning permission is not required for a building or other land to change from one use within that class to another use within that same class. The UCO 1987 was made by the Secretary of State under authority granted by sections 22 and 287 of the Town and Country Planning Act 1971, which have subsequently been replaced by sections 55 and 333 of the Town and Country Planning Act 1990.
