Supplying the Council

The process for supplying us with services or goods


  • Tender opportunities
  • Procurement Alliance for Essex (PAE) and Winning the Contract e-Course
  • Modern Slavery Act
  • Contracts Register

The Council purchases a range of goods and services to support our operations and to deliver high-quality services to local residents, businesses and visitors.

The Council's procurement processes include:


Tender opportunities

As a local government authority, we are bound by the Public Contracts Regulations 2015. Public sector opportunities which are open to all bidders are advertised on the Contracts Finder website (www.gov.uk/contracts-finder), which includes notices issued by Colchester Borough Council as well as other public sector bodies across the UK.

We conduct our tender processes electronically using the Delta procurement portal - https://www.delta-esourcing.com/ . To respond to any new contract opportunities issued by the Council, your organisation has to be registered as a supplier on the Delta portal.  Assistance with registration can be provided through the Delta helpdesk - https://www.delta-esourcing.com/contact/ - with further information about their Response Manager at - https://www.delta-esourcing.com/suppliers/response-manager/. 

Each tender or opportunity is advertised separately and has a unique Access Code, which is linked from the contract notice.   Tenders may be conducted separately or jointly for the Council, Colchester Borough Homes, Colchester Amphora Energy Ltd, Colchester Amphora Homes Ltd and Colchester Amphora Trading Ltd.

All contract opportunities are classified using CPV codes.  CPV means Common Procurement Vocabulary and is a way for the whole public sector to classify or categorise similar works, goods or services.  This link - https://www.bipsolutions.com/cpv-code-search/ - has a dynamic structure of the codes. You can drill down to find more specific codes under the main headings but it does depend which level of classification has been used by the contracting authority.  You may wish to use the CPV codes to set up alerts through the Delta portal or Contracts Finder to notify you of new opportunities that are relevant to your business.

To find our latest tender opportunities go to:

The Delta procurement portal can be accessed directly through :

Contract notices and tender opportunities are published on Contracts Finder for Colchester Council and other public sector bodies through: 

​Where applicable tender opportunities can also be found in OJEU notices on a number of websites.


Dynamic Purchasing Systems

The Dynamic Purchasing System (DPS) is another type of procurement process that we can use to award contracts for works, services and goods and is conducted electronically. As a procurement tool, it has some aspects that are similar to a framework agreement, but allows new suppliers to join at any time.

Each DPS has two stages:

  • Application to Join the List – interested contractors must submit an application for approval before being added to the List – this is in addition to registration as a supplier on Delta
  • Quote for Work Packages – during the lifetime of the DPS, a number of separate work packages will be offered.  Only contractors on the DPS List will receive the invitation and for each opportunity, can choose whether to submit a bid or not.

Colchester Borough Council for itself and its wholly owned bodies have issued contract notices for two separate DPS projects. The titles and link are below:

Each notice, issued through the Delta portal, has a short description of our requirements and a link to click to ‘Register Interest’.  Suppliers are then asked to log in or register on Delta to access the documents and questionnaire to apply to join the DPS List.  Further information is available in the quick help guide to the DPS in the link below.

Procurement Alliance for Essex (PAE)

The Procurement Alliance for Essex (PAE) works to promote and facilitate collaborative procurement across Essex.


Modern Slavery Act

The Council has statutory obligations under the Modern Slavery Act 2015, including within Section 54 to ensure that modern slavery does not exist in its supply chain. In July 2018 the Council also agreed unanimously to adopt and apply the Co-operative Party’s Charter Against Modern Slavery (as far as is legally possible). As part of this Charter, suppliers are reminded that contacted workers are free to join a trade union and are not to be treated unfairly for belonging to one.

All Suppliers to the Council will be asked to confirm that they/their organisation has, and will, take action to address risks to human rights identified within itself and its supply chain. This action is to include the adoption of a whistleblowing policy that enables staff to blow the whistle on any suspected examples of modern slavery. If risks are identified or for more information see the National Referral Mechanism on the link shown below.

Contracts Register

Contracts and tenders for goods and services over £5,000 are published on Datashare as a downloadable CSV file. All councils are required to publish this information on a quarterly basis under the Local Government Transparency Code.
