Creative England and the Creative Industries Federation have merged to become Creative UK.
The amalgamation has been made official about a year later than expected, though the parties have worked together under a holding company since early 2020.
The new entity's purpose is to "harness the power of creativity and amplify the voice of its membership to build a fairer and more prosperous world".
"By coalescing the collective capabilities of Creative England and the Creative Industries Federation, and drawing on the insights and experience of our growing membership, we are perfectly positioned to have visible impact and drive real change," Chief Executive Caroline Norbury said.
Head of Brand Rachel Johnson said a new website and logo signifying amplification reflects "an inclusive and cohesive identity that reflects the ambition, diversity and scope of the new organisation".
