Under an Act passed by the UK Parliament in 1931, there was established an Architects' Registration Council of the United Kingdom (ARCUK), referred to in the Act as "the Council". The constitution of the Council was prescribed by the First Schedule to the Act. The Act made the Council a body corporate by the name Architects' Registration Council of the United Kingdom. It was habitually referred to colloquially by the acronym ARCUK.
When the Warne Report was published in 1993, it was found that its principal recommendation was abolition of this body. Instead, after a consultation process conducted by the Department of the Environment this body has been reconstituted and renamed as the Architects Registration Board. It now operates under the Architects Act 1997.
