How to sell through CCS

How to register, where to look for opportunities and how bidding works.

There are several places to look for opportunities to sell your products and services to the UK public and third sector through CCS:

To become a supplier through CCS you have to respond to a contract notice and succeed in the tender process. Details of how to register your interest in a tender are contained in the contract notice. There are no joining fees. You pay a management charge based on how much buyers spend with you.

How to register so you can respond to an opportunity

You then have to register on CCS’s eSourcing tool to participate in tender opportunities. Public sector buyers use the eSourcing tool to buy goods and services and request for bids.

To register you will need to provide:

  • Full legal name of your organisation
  • DUNS number – unique 9-digit number provided free of charge by Dun & Bradstreet
  • Profile describing your organisation.

How to respond to a request

Each procurement opportunity includes response guidance for each question. Read the guidance and respond accordingly. The people evaluating your responses are required to use the same criteria as published in the response guidance.

Government wants to encourage small and medium sized businesses (SMEs) to supply the public sector. CCS has written further guidance for SMEs.

How supplying through CCS is organised

CCS commercial agreements are published as frameworks, catalogues, and dynamic purchasing systems.

CCS frameworks comprise common public sector requirements, a list of suppliers who have been evaluated as capable of delivering the requirements, and standard contract terms.

Frameworks can be divided into lots by product or service type. You can supply to one or more lots or an entire framework.

Once successful suppliers have been allocated to a framework, tenders close and new suppliers can’t join. The exception is a dynamic purchasing system (DPS). This is an agreement that allows suppliers to join and leave at any point.

Where there is more than one supplier on a framework, or within a lot, suppliers may need to compete further to bid for work. This is known as a further competition.

On a DPS buyers can search using a range of criteria to identify suitable suppliers. Once a list of suppliers has been identified, the buyer will then run a further competition.


A contract is awarded, through competition, to a supplier to provide goods or services. Once the contract is in place, buyers named in the contract can buy directly from that supplier using the agreed standard contract terms at a fixed price.

Scotland, Wales and Northern Ireland have their own procurement websites.
