Dynamic Purchasing Systems (DPS): A Complete Guide for UK Suppliers

A Dynamic Purchasing System (DPS) is one of the most accessible procurement routes in UK public sector — unlike traditional frameworks, new suppliers can join at any time during a DPS's lifetime. This guide explains what a DPS is, how it differs from a framework, and how to maximise your success on DPS opportunities.

What Is a Dynamic Purchasing System?

A Dynamic Purchasing System (DPS) is a procurement route used by UK public sector organisations to manage a pool of pre-approved suppliers for a category of goods or services. The key difference from a traditional framework is that a DPS remains open to new supplier applications throughout its lifetime — any qualified supplier can join at any time. This makes DPS more flexible and competitive than traditional frameworks. Buyers benefit from a continuously updated supplier pool. Suppliers benefit from being able to join without waiting for a framework renewal.

How Does a DPS Work?

A DPS operates in two stages. In Stage 1 — joining the DPS — suppliers apply by demonstrating they meet the selection criteria. If you meet the criteria, you join. There is no competition at this stage. In Stage 2 — call-offs — when a buyer wants to procure something through the DPS, they run a mini-competition among all suitable DPS suppliers. All DPS suppliers in the relevant lot are typically invited to bid. The buyer evaluates responses and awards the contract. Being admitted to a DPS does not guarantee you will win work — you must still compete in each call-off.

DPS vs Framework: Key Differences

Always open — a DPS accepts new suppliers throughout its lifetime. Traditional frameworks close to new applications once established
All suppliers compete — in a DPS call-off, all suitable suppliers are typically invited. In a framework further competition, buyers may select a subset
No direct award — DPS call-offs almost always require competition. Frameworks often allow direct award below certain values
Longer life — DPS systems can run for up to 10 years. Frameworks typically run for 2–4 years

How to Join a DPS

To join a DPS, respond to the admission notice published on Find a Tender Service or the buyer's portal. The admission application typically requires standard selection questions covering financial standing, insurance, and policies, plus evidence that your services meet the DPS lot requirements. Once admitted, you remain on the DPS until it expires or you choose to withdraw. Admission is typically evaluated within 10–30 days.

Winning Business Through DPS Call-Offs

Respond to every relevant call-off — you will only win if you bid. Set up monitoring so you are notified of DPS call-offs in your areas of interest
Be quick — DPS call-off timeframes are often shorter than open tenders. Having well-prepared bid content ready to adapt is essential
Build relationships — even within a DPS, buyers have preferences. Engaging with buyers outside procurement processes builds relationships that influence how they specify requirements
Track your performance — record your win rate on DPS call-offs. Understand which buyers you are winning with and which you are not, and why

Frequently Asked Questions

Can SMEs join a DPS?

Yes. DPS systems are generally designed to be accessible to suppliers of all sizes. The selection criteria focus on capability and financial standing relative to the contract values, not company size.

How long does DPS admission take?

Most DPS operators aim to evaluate admission applications within 10–30 days. The process is typically faster than framework applications because there is no competitive element to admission.

Can I be on multiple DPS systems simultaneously?

Yes. There is no restriction on being listed on multiple DPS systems at the same time. Many suppliers are listed on several DPS systems covering different categories or geographies.

How do I find DPS opportunities?

DPS notices are published on Find a Tender Service. Search for 'DPS' or 'Dynamic Purchasing System' combined with your service keywords. WinAContract aggregates DPS opportunities alongside other procurement notices.

What is the difference between a DPS and an open framework?

A DPS accepts new supplier applications throughout its lifetime — any qualifying supplier can join at any time. A framework closes to new applications after the initial application window. Both require competition at the call-off stage.
