What Cambridge Water does
Cambridge Water is a regulated regional water utility in eastern England, supplying drinking water to approximately 351,000 household customers across the Cambridge region — spanning from Ramsey in the north to Melbourn in the south and from Gamlingay in the west to Balsham in the east. The franchise is operated as a brand under South Staffordshire Water PLC within the South Staffordshire Group, alongside the group's sister utility South Staffs Water. Water is sourced entirely from groundwater, abstracted through 24 boreholes into the chalk aquifer that underlies the supply area.
The company's core operational stack centres on the MyAccount digital platform — a customer portal and iOS/Android mobile application that handle billing, payments, meter reading submission and account self-service — augmented by advanced meter reading infrastructure (including bin-lorry-mounted mobile readers), drone-based asset inspection, CCTV monitoring, and the Utilis satellite leak detection system delivered through SUEZ. This satellite capability covers 3,500km of imagery and forms the backbone of the 15% leakage reduction commitment and the targeted renewal of 250km of pipework through a £84 million capital programme running 2025-2030.
Revenue is generated primarily through regulated water supply charges billed to residential customers (some of the lowest bills in England and Wales), with secondary streams from non-household wholesale supply under OpenWater, developer connection charges, standpipe hire, and an affinity-marketing partnership with Homeserve for water-related insurance products. The company also operates community-facing programmes including the H2Online customer engagement community, the PEBBLE biodiversity fund (grants up to £10,000), the SPRING 2 catchment management scheme (grants up to £15,000 per farm), and a school education programme that engaged nearly 600 pupils in 2025/26.
