Procurement Act 2023 Supplier Obligations in the UK
The Procurement Act 2023 imposes supplier obligations including Central Digital Platform registration for many procurements, integrity and exclusion rules, subcontracting transparency, and compliance with revised award and challenge procedures. UK suppliers must understand these duties before bidding — not discover registration, debarment or payment-term requirements when compiling mandatory returns.

Why this matters commercially
Non-registration on the Central Digital Platform can block participation in regulated procurements.
Mandatory exclusion grounds and integrity declarations — false statements carry debarment risk.
30-day payment terms to subcontractors are statutory — primes must flow down compliance.
Act changes affect standstill, transparency and how suppliers track pipeline opportunities.
How suppliers usually do this manually
Bid teams treat the Act as buyer-only — miss supplier registration and declaration requirements.
Subcontractor payment practices not audited before prime bids on Act-covered contracts.
Integrity questionnaires answered without legal review of exclusion grounds.
No monitoring of Act commencement timelines and transitional provisions per authority.
Signals worth tracking
ITT references Procurement Act 2023 and Central Digital Platform supplier registration.
Mandatory exclusion and debarment declarations in bid submission portals.
Subcontracting disclosure schedules requiring named subcontractors and payment terms.
Find a Tender notices tagged under new Act procedures and transparency requirements.
Buyer guidance on transitional arrangements from PCR 2015 to Act 2023.
Common mistakes to avoid
Bidding without completing supplier information on the Central Digital Platform.
Incomplete integrity declarations — inaccurate answers trigger exclusion risk.
Prime contractors ignoring subcontractor payment compliance obligations.
Assuming old PCR 2015 templates satisfy new Act mandatory returns.
Missing updated standstill and challenge procedures on award notifications.
