Title: CCS deliver second water aggregation with great success

Deregulation of the water market

Last year, for the first time, the water market was deregulated allowing 1.2 million non-household customers to choose their water supplier. By switching water supplier, organisations could benefit from streamlined account management, lower bills and better value for money.

As such, CCS, in collaboration with other public buying organisations, developed the Water, Wastewater and Ancillary Services framework (RM3790) to provide public sector organisations with a simplified procurement to access these benefits.

Commenting on the framework, Sam Ulyatt, Strategic Category Commercial Director for Buildings at CCS, says:

“In April 2017, we brought the largest public sector water framework agreement to the UK market. The agreement is supporting the public sector to receive whole life value in service and costs, reduced on customer water bills”.


Aggregation is the process of bringing together the requirements of multiple customers to increase buying leverage, promote competition between framework suppliers and drive down retail margins.

Following the success of CCS’ first aggregated further competition for water and wastewater servicing, a second aggregation was carried out in October 2018, consolidating the requirements of 155 organisations across the public sector. Following active bidding from 5 competing suppliers at the e-auction held on 11 October 2018, outstanding low retail margins emerged for both monthly and quarterly billing options. On average, customers signing a call off under the framework will pay 2% for their water servicing by switching to the recommended supplier; Castle Water Ltd. Typically this will result in a saving of 4-10% on customer retail charges.  

Within hours of awarding the contract to Castle Water Ltd, a number of customers submitted call offs to CCS and took early advantage to switch supplier, ready for supply from 1 December.

Commenting on the framework, Sam Ulyatt, Strategic Category Commercial Director for Buildings at CCS, says:

Sam Ulyatt commented:

“By leveraging the buying power of the public sector, we are supporting the delivery of efficient and effective public services.”
