Dynamic Purchasing Systems (DPS) Explained for UK Suppliers
What DPS frameworks are, how they differ from traditional frameworks, and why they are one of the best entry points for new suppliers.
A Dynamic Purchasing System (DPS) is an electronic system set up by a contracting authority (like the NHS, a council, or CCS) to purchase commonly used goods, works, or services. Unlike traditional frameworks, a DPS remains open to new suppliers throughout its lifetime — making it one of the most accessible routes into public sector contracting for SMEs and new market entrants.
This guide explains how DPS works under UK procurement law, how to join one, and how to convert DPS membership into actual contract awards.
DPS vs. Traditional Framework: Key Differences
| Feature | Traditional Framework | Dynamic Purchasing System |
|---|---|---|
| Open to new suppliers | Only at re-procurement | Continuously |
| Duration | Fixed (usually 4 years) | Up to 10 years |
| Mini-competition | Required for most awards | Required for each award |
| CPV scope | Fixed at setup | Can be expanded |
| SME friendly | Moderate | High |
| Award speed | Weeks to months | Days to weeks |
1How to Join a DPS
Joining a DPS is simpler than winning a full tender, but it still requires preparation. Here is the typical process:
- Find the DPS notice on Find a Tender or Contracts Finder. Look for keywords "Dynamic Purchasing System" or "DPS".
- Complete the Selection Questionnaire (SQ) — usually covers financial standing, insurance, technical capacity, and previous experience.
- Submit supporting documents — accounts, insurance certs, policies (ISO, equality, etc.).
- Wait for admission — the authority must admit you within 10 working days if you meet the criteria. If rejected, they must explain why.
Important: Once admitted to a DPS, you are not guaranteed any work. You must still win individual call-off contracts through mini-competitions.
2Winning Mini-Competitions
When a buyer needs something, they invite all DPS members (or a filtered subset) to bid. This is called a mini-competition. The award criteria are set out in the original DPS notice.
Tips for winning DPS mini-competitions:
- Respond fast — short turnaround times (5-10 days) are common
- Know your DPS terms — your original admission docs become your baseline
- Monitor the DPS portal daily — opportunities appear with little notice
- Build a relationship with the DPS manager — they can tell you what buyers want
- Price competitively — DPS mini-competitions often weight price higher than full tenders

Less ideal if:
