Customers rely on us every day for clean, clear drinking water, effective wastewater services, accessible support and reliable communication.

We know trust is built through consistent service, fair treatment and the way we respond to people’s needs.

 

Our customer focus is about more than answering queries. It includes providing affordable support, improving accessibility, helping customers in vulnerable circumstances, maintaining reliable supplies and reducing the impact of wastewater service issues. By listening to customers and using insight to improve the way we work, we can deliver better experiences and support those who need extra help.

Delivering excellent customer service

Providing excellent customer service sits at the heart of our purpose. In 2025/26, we ranked first overall in the industry for C-MeX, Ofwat’s measure of customer experience, with a year-to-date score of 75.17.This is the third time in six years that we have topped the C-MeX table, and we are the first company to retain first place for two consecutive years.

C-MeX combines feedback from customers who have contacted their water company with wider customer perceptions of the service they receive.Our performance reflects the focus of colleagues across the business on getting things right first time, communicating clearly and resolving issues quickly. We remain focused on continuous improvement, using customer insight, engagement and feedback to improve customer journeys and make it easier for customers to interact with us.

Supporting customers with affordability

Affordability remains a significant pressure for many households, and we are committed to helping customers access support when they need it.Through affordability schemes and targeted support programmes, we currently support more than 160,000 customers, providing financial help and tailored assistance. Our Water Without the Worry campaign helps bring this support together, making it easier for customers to understand what help is available.

We are also using data and partnerships to identify customers who may be missing out on wider financial support. Through Policy in Practice8,802 customers were identified as potentially missing out on benefits, with an average potential gain of £478 a month. As part of our 2025–30 commitments, we plan to expand affordability support from approximately £40 million to £170 million, double the number of households supported through social tariffs to 300,000, and introduce a £20 million shareholder-funded hardship scheme.

Reducing wastewater service disruption

Sewer flooding can be highly disruptive for customers, businesses and communities. We are focused on reducing the likelihood of incidents, improving operational response and supporting customers when issues occur.

In 2025/26, internal sewer flooding reduced to 0.54 incidents per 10,000 wastewater connections, a total of 72 incidents. This was an improvement on 136 incidents in 2024/25 and significantly ahead of our 2025/26 target.This progress reflects targeted operational improvements, proactive maintenance, increased use of data and insight, and greater field resource across the wastewater network.
