Ownership of ADVANCE transitioned to an Employee-Owned Trust (EOT), marking a pivotal shift in our culture. As part of this evolution, Anna Sills, who joined the company in 2014, was appointed Managing Director, while Shaun Critchley transitioned to Chair of ADVANCE Group Holdings.
In preparation for the Joint and Several Liability and Employment Rights Act 2024, the business underwent a strategic restructuring. This period was marked by the commissioning and development of our pioneering TRANSPARENCY Portal with Individual PAYE References.

Building on this momentum, ADVANCE successfully secured positions on several high-profile Preferred Supplier Lists (PSLs) as a direct result of the TRANSPARENCY Portal and its individual PAYE references. This milestone marks more than just a successful year; it signals a fresh chapter for the business. With our new Managing Director now at the helm, ADVANCE is entering a dynamic new era of workforce management. Under this energised leadership, the business is leveraging its reputation and legacy of thought-leadership to raise standards for the industry that go significantly above the fundamental government requirements.
