Vehicle Conversion DPS

Contract ID: RM3814

Start Date: 24/08/2017

End Date: 23/08/2023


This agreement utilises a Dynamic Purchasing System (DPS), which is a public sector sourcing tool for services and goods (Public Contracts Regulations 2015). It is similar to an electronic framework, but new suppliers can join at any time. This is a wholly electronic way of sourcing, but suppliers and customers do not need any special IT equipment. It  eliminates unnecessary activity for the supplier up front.

Public sector fleet teams frequently need to convert their vehicles to be suitable for different operational purposes. Some level of vehicle modification is supported by the vehicle manufacturer, however, there are many vehicle changes which require a specialist conversion.

The CCS Vehicle Conversions DPS fulfils this requirement; upon application to join the DPS, suppliers indicate which elements and services they are able to bid for under the DPS. The elements are organised into a matrix of filters, comprising:

  • Geography
  • Sector
  • Vehicle type
  • Service types
  • Product and sub-product

Full details of goods and services in scope, and the filtering can be found within the Customer Guidance document under the Documents tab.


The DPS offers a number of key benefits for both customers and suppliers:

  • Simpler, quicker process - perfect for SMEs looking to access to public sector business
  • Automated, electronic process - using existing supplier selection tools and systems
  • Flexible - new suppliers can apply to join at any point, increasing the potential capacity
  • Choice - increased scope/scale of service offerings
  • Filtering of supplier offering - ensures suppliers receive notifications of relevant competitions
  • Dynamic - customers can build specifications, competitions and contracts in a way to suit them
  • Supports localism and social value - enabling suppliers to bid for business: locally, regionally or nationally. Allowing customers to undertake competitions between both national and local suppliers to suit their requirements.
  • Opportunity to access wider supply chain - for specialist services or where supplier may previously have been a subcontractor

The Vehicle Conversion DPS is accessed via the Supplier Registration Service on the website

Follow the steps below to register on the Suppler Registration Service and access the DPS:  

                  a. View appointed suppliers

                  b. Click on the link to create a new category export. This is how you filter the suppliers that can meet your requirements

  • Use the filtering tool to specify your conversion requirements, including geographical region(s). This will create a list of capable suppliers
  • Export the list of suppliers and contact details (export is to an Excel spreadsheet).
  • Quit the DPS
  • Use the list to run a further competition. Invite the suppliers identified by the DPS to bid against your detailed specification, evaluation criteria and contract format

                       a. The list is valid for only 2 working days, because new suppliers may be applying to join at any point. If your further competition excludes                             eligible suppliers it potentially breaches procurement regulations. Obtain a fresh supplier list (steps 3b to 5) if you don’t use your list                                     within 2 working days.

                       b. You can use CCS’s eSourcing tool to run a further competition. The tool is free to use for public sector buyers.

  • Allow at least 10 days for supplier responses, or longer for more complex requirements
  • Evaluate the responses
  • Request from winning supplier(s) any required evidence that they can meet your requirements. Set them a deadline for submitting evidence of 2 days.
  • If you’re satisfied with the evidence, award the contract
  • Where appropriate, notify of the award on Contracts Finder.

More detailed guidance is available under the documents tab.

The Vehicle Conversions DPS was developed to provide you with a flexible route for the sourcing of vehicle conversion goods and services, to be able to access a wide scope of provisions, and design your competition and contracts in a way which suits your operational demands.

The DPS is also beneficial to suppliers, in a market where more than 97% of suppliers are SMEs. The DPS is less resource intensive supports access by SMEs and allows for you to build in Social Value elements that are important to you.

The Dynamic Purchasing System (DPS) is a replacement of: RM956 Vehicle Conversion and Reconditioning Services (which was a framework agreement).

A wide range of customers stakeholders were involved in the planning of the new agreement, and many other organisations were consulted for their feedback on the current framework and expectations of it’s replacement. Stakeholders helped to determine that, given the wide and changing scope of the conversions market, a DPS would provide the best route to market for this product/ service group.

CCS followed the Restricted procedure, as required for a DPS, published an OJEU Contract Notice and allowed an initial 30-days for suppliers to apply to join. Thereafter, the DPS was opened and appointed suppliers could commence bidding and carrying out contracts. New suppliers can continue to apply to join at any point during the life of this DPS.
