Question to the Ministry of Housing, Communities and Local Government:

To ask the Secretary of State for Housing, Communities and Local Government, with reference to the Written Statement of 23 October 2025 entitled Delivering ambitious and high-quality sustainable growth in Greater Cambridge, HCWS990, what (a) water efficiency and (b) water interventions are being proposed; and whether they include changes to how households are billed for (i) water and (ii) waste water.

The government’s water efficiency programme and wider water package will fund a range of measures to generate water savings and offset new development in Greater Cambridge. The first phase of the efficiency programme will roll out water retrofits in social housing and public buildings. The second phase and wider package is currently under development. The overall package is funded by government and will not impact on how households are billed.

Anglian Water is responsible for wastewater infrastructure for the Greater Cambridge area and Cambridge Water is responsible for water supply. Ofwat sets a price cap every five years for each water and sewerage company, which limits the maximum amount it can increase customer bills. Companies then use this price limit to set their individual bills.
