Aggregations are where we match customers with similar requirements for common goods and services, allowing them to buy as a single customer and leverage on the higher volume with suppliers pricing and added extras. Since this was launched in 2017, we have helped our customers save up to 10% against the retail average, reducing annual bills by £100 to £10,000 depending on the estate size.

This further competition is open to all public sector, non-residential premises and will allow participating customers to switch their retail supplier.  We will combine the requirements of participating customers to increase buying power to secure the best retail margin for water and wastewater services. Customers will also benefit from high standard servicing from a dedicated customer service team.

With the past successes we have had, we are running another Lot 1 – Water and Wastewater supply aggregation in early October. To get involved please download and complete theRM3790 Switching template v9 and email the document to us by 25 September 2019.
