Water, Wastewater and Ancillary Services 3


Water supply, wastewater (sewage) and ancillary services that make usage more efficient and supply more resilient.


This is a renewal of the RM6178 waste supply and wastewater agreement.

It will run for 4 years and is open to all public sector, non-residential premises in England, Wales and Northern Ireland. For example: schools, NHS trusts and local authorities.

Businesses, charities or public sector organisations currently served by a water supplier based in Wales are only eligible to switch water retailers if they use more than 50 million litres of water a year. Otherwise they will continue to be served by their regional water company.

If your business premises are in Wales and your usage is above the 50 million litre threshold, you can choose to remain with your current retailer or switch.

You can contract with a supplier at any time during the agreement, and run a contract for up to a maximum of 4 years from when supply starts.

Buyers can run a mini-tender or join a  CCS quarterly aggregation. As of 1 April 2017 eligible, non-household customers (those that pay business rates) can choose their water supplier. Ofwat has published full eligibility guidance and supplementary guidance.
