Two routes onto the buyer's list
Framework vs Dynamic Market: Which and When
Published by BidSquirrel · checked against legislation.gov.uk and gov.uk · last reviewed July 2026
Frameworks and dynamic markets are both ways for buyers to pre-approve a pool of suppliers and then award work to them without running a full competition each time. They sound similar, and suppliers often lump them together, but they behave very differently - and the difference decides whether you can get on board now or have to wait years for a window.
Under the Procurement Act 2023, the old Dynamic Purchasing System (DPS) has been replaced by the dynamic market, which is broader and more flexible. Frameworks remain, now joined by a new open framework that adds some flexibility of its own. This guide explains how each works, the timing trap that catches SMEs, and which to chase depending on where you are.
How a framework works
A framework agreement is a list of suppliers appointed for a fixed period, usually up to four years for a general framework. The buyer runs one competition to select that pool, and then for the life of the framework awards individual contracts ("call-offs") to suppliers on it - sometimes by direct selection, sometimes by a mini-competition among the appointed suppliers. The terms of those call-offs are largely set by the framework itself.
The catch for SMEs is timing. A standard framework is closed: once it is awarded, the door shuts for its full term. If you miss the competition, you wait - potentially up to four years - for the next one. The Procurement Act's new open framework softens this by allowing a scheme to reopen at set points so new suppliers can join during an extended term, but a traditional closed framework still locks latecomers out.
How a dynamic market differs
A dynamic market is the opposite where it counts: it stays open for suppliers to apply to join at any point during its life. There is no single closing date you can miss. If you meet the published conditions for membership, the buyer must consider your application within a reasonable period and admit you. That open door is the defining feature, and the reason dynamic markets suit newer or growing firms.
- Suppliers can apply to join at any time, not only at a fixed competition - no closed-door wait
- Unlike the old DPS, a dynamic market can be used for all procurement types, not just off-the-shelf goods and services
- Each contract awarded through it is a standalone agreement, with a fresh tender notice for each requirement
- Membership gets you into the competitions; it does not by itself win you work
- Joining is an admin and qualification exercise, not a one-shot bid you can be shut out of
Which to pursue, and when
The decision is mostly about timing and certainty. If a framework competition for your kind of work is open now, and the framework is well used by buyers you want to sell to, pursuing it is worth the effort - a place on a busy framework can carry years of call-off work. If the relevant framework is mid-term and closed, there is no point staring at it; look instead for a dynamic market in your field you can join today, and for the next framework refresh on the horizon.
For a smaller or younger firm, the dynamic market is often the more realistic entry point precisely because you cannot be locked out: you join when you are ready, then compete for the contracts that flow through it. The pragmatic stance is to hold both in view - join the open dynamic markets that fit you now, and time your run at the closed frameworks for when their windows actually open.
One more practical difference shapes how you treat each. Because a framework largely fixes the terms of its call-offs in advance, much of the commercial work is done at the point you join, and the call-offs that follow can be quick. A dynamic market requires a fresh tender notice for each requirement, so the membership is lighter to obtain but the work that flows through it is competed contract by contract. Neither is better in the abstract; they suit different rhythms of buying, and knowing which you are dealing with tells you where your effort will fall.
A reality check on both
Neither route is a shortcut to revenue. A framework place and a dynamic market membership both get you into the room; they do not hand you contracts. Plenty of suppliers win a coveted framework slot and then win nothing off it, because the call-off competitions still have to be won on quality and price like any other bid.
So treat membership as access, not arrival. The work that follows is still won the ordinary way - by qualifying hard, then writing answers that score. Our guide on how tenders are scored covers what wins the call-offs once you are on the list.

Frequently asked questions
What replaced the DPS under the Procurement Act 2023?
The dynamic market. It does the same core job as the old Dynamic Purchasing System - an open, joinable supplier pool - but is broader, because it can be used for all procurement types rather than only off-the-shelf goods and services.
Can I join a framework after it has started?
Generally not a closed framework - once awarded, it is shut for its term, often up to four years. The Procurement Act's new open framework can reopen at set points to admit new suppliers, but a traditional closed framework locks latecomers out until the next competition.
Does joining a dynamic market win me contracts?
No. Membership gets you into the competitions that run through the market; you still have to win each one on quality and price. It removes the closed-door problem, not the need to bid well.
