A Dynamic Purchasing System (DPS) is a flexible procurement framework allowing public bodies to add new suppliers throughout its duration, combining competitive tendering with the ability to expand the supplier pool as needed.
A Dynamic Purchasing System (DPS) is a procurement framework that allows contracting authorities to admit new suppliers at any time during the system's operation, provided they meet the qualification criteria. Unlike traditional frameworks with closed supplier lists, a DPS remains 'open' for new entrants throughout its entire lifespan, typically up to four years.
The DPS operates in two distinct phases. First, the contracting authority establishes the system by publishing an OJEU/Find a Tender notice outlining the qualification criteria and technical specifications. Suppliers can apply to join at any point during the system's operation, and the authority must assess applications within a maximum of 20 working days under the Public Contracts Regulations 2015.
Once admitted to the DPS, suppliers can participate in mini-competitions for specific requirements. The authority issues invitations to tender to all relevant DPS suppliers, who then submit competitive bids. This process combines the speed and efficiency of framework agreements with the ongoing competitive opportunities of open tendering.
DPS arrangements particularly benefit rapidly evolving markets where new suppliers regularly emerge or where innovation is crucial. Technology sectors, professional services, and construction often utilise DPS structures because they accommodate market changes while maintaining competitive pressure throughout the system's life.
The continuous admission process prevents supplier monopolisation and ensures fresh competition, whilst the pre-qualification element provides authorities with vetted suppliers ready to respond quickly to requirements. This balance makes DPS especially suitable for high-volume, repeat procurement needs where market conditions change frequently.
Under the Public Contracts Regulations 2015, DPS procedures must follow specific rules including mandatory electronic communication, standardised qualification criteria, and strict timescales for supplier admission. The regulations permit DPS use for most procurement types except certain utilities and defence contracts, with the same EU threshold values applying as for other regulated procedures.
Authorities must ensure equal treatment of all DPS suppliers and cannot discriminate between established and newly admitted suppliers when issuing tender invitations. This requirement maintains competitive integrity whilst allowing market evolution throughout the system's operation.
