The Importance of The Common Assessment Standard

SSIP accreditation alone is no longer sufficient for most government contracts. Contractors looking to win work or keep existing contracts in the public sector will now need to highlight compliance above and beyond the SSIP accreditation.

New Procurement Policy Note (PPN 03/23)

The Procurement Policy Note (PPN) 03/23 now requires contracting authorities in the public sector* to align their supply chains compliance with the Common Assessment Standard (CHAS Elite) to remain competitive.

The revised PPN is a move that officially adopts a recommendation outlined in the report Constructing the Gold Standard — an independent review of public sector construction frameworks in 2021 by the Centre of Construction Law at King’s College London. It is also a response to calls from construction industry players asking the government to update PPN 08/16 by supporting a standardised selection questionnaire (SQ).

*Check whether PPN 03/23 applies to you by heading to the PPN 03/23 Standard Selection Questionnaire (SQ).
