What is a DPS? A Dynamic Purchasing System (DPS) allows a contracting authority to purchase goods, services and works for which they have a regular need, without having to carry out a full procurement process for each individual purchase. Procurement via DPS is intended for common use items that are generally available on the market and meet the contracting authority’s requirements. A DPS is a two-stage process involving an initial procurement stage followed by individual call-off stages. DPS awards are conducted electronically and governed by the restricted procedure under the Public Contracts Regulations 2015, SI 2015/102, reg 28, subject to the additional rules specific to DPS under in PCR 2015, SI 2015/102, reg 34.
