Frameworks and dynamic markets explained for small contractors
Last reviewed 25 October 2026
A lot of public building and maintenance work isn't tendered job by job. It goes through frameworks and dynamic markets, which decide in advance which suppliers can be offered the work. Knowing how they work helps you decide which tenders are worth the effort.
Frameworks
A framework is an agreement between one or more buyers and a group of suppliers, setting out the terms for future contracts. Suppliers compete once to get onto the framework. Individual jobs ("call-offs") are then awarded to framework members, either directly or through a quick mini-competition between them.
- Under the Procurement Act 2023, a framework normally lasts at most four years (eight for defence and utilities), unless the buyer explains why it needs longer.
- Getting onto a framework is not a guarantee of work. Some members get a steady stream of call-offs; others get none.
- Large regional and national frameworks often have several "lots" by trade or area. Bid for the lots that match what you actually do.
- The Act also allows "open frameworks", which reopen at set points so new suppliers can join.
Dynamic purchasing systems and dynamic markets
Under the old rules, a dynamic purchasing system (DPS) was a list of approved suppliers that stayed open, so firms could apply to join at any time. The Procurement Act 2023 replaces DPSs with dynamic markets, which work in a similar way: you apply to join, and once accepted you can be invited to compete for contracts awarded through it. Existing DPSs set up under the old rules carry on until they end.
Should you join?
Usually yes, if all of these are true:
- the buyers using it are in your area and buy the kind of work you do;
- you can meet its entry requirements (insurance, accreditations, turnover) without stretching;
- you'll have time to respond quickly when call-offs or mini-competitions come round.
Joining a dynamic market is often less work than a full tender, and because they stay open, it's a good way into public work for a small firm. A large national framework with a heavy application is a bigger decision.
When a tender is a large multi-year framework, the Toolbox Tenders email says so under "Watch out", so you can tell it apart from a one-off contract before you open the notice.
