Anglian Water Services results for the year ended 31 March 2026

Over the past year, Anglian Water invested £1.1 billion in delivering its biggest ever capital investment programme to 2030. The company made good progress on vital infrastructure to improve services, support customers and protect the environment.

Delivery was underpinned by strong financial performance, with increases to revenue and profits enabling the business to invest for the future. Revenue rose by 20% to £2.1 billion, with operating profit increasing by 28% to £636 million. This is supporting a significant increase in investment, with capital expenditure exceeding operating profit - meaning that for every £1 generated in profit, £1.78 was reinvested into maintaining and improving assets.

Chief Executive Officer, Mark Thurston, said:
“This year has been one of reset, mobilisation and renewed focus for Anglian Water, as we started delivering the most ambitious investment programme in our history and strengthened the business for the years ahead. This programme reflects our long-term responsibility to provide resilient water and wastewater services that support communities, protect the environment and enable sustainable growth across our region and ultimately deliver on our Purpose to bring environmental and social prosperity to the communities we serve.”

2025/26 was the first year of a major five-year programme designed to make services more resilient in the face of climate change, population growth and ageing infrastructure, while improving performance for customers.

This year, Anglian Water worked on more than 1,100 capital projects, more than double the annual delivery rate achieved in AMP7 (2025-2030). Highlights include:

• 140.5km of new water mains to strengthen network resilience
• Over 316,000 smart meters installed to help customers manage water use and spot leaks earlier
• Progressed major infrastructure projects, including its strategic interconnecting water grid to secure future water supplies, with customers across the Ipswich and Colchester areas already benefitting from the new network

To measure the company’s progress towards its AMP8 (2025-2030) outcomes, Ofwat sets Anglian Water targets as part of its business planning process. These measures were decided during the 2024 Price Review and are known as Performance Commitments.  This year, the company met some, but not all, of its Performance Commitment Levels. It reports a net outcome of £-10.5 million*, a significant improvement on the prior year, where it netted out at £-41.5 million*.

Anglian’s focus on operational resilience and environmental compliance contributed to a reduction in total pollution incidents, its best-ever storm overflow performance and record bathing water quality across the region. Total pollutions reduced by 66 to 371 (2024: 437). However, the company was disappointed to see an increase in serious pollution incidents, from seven (2024) to 12 (2025). This is a key area of focus to build trust, and the business is working hard to improve its performance as it heads into the next year.

Across water supply measures, the drier year saw Anglian Water contend with other challenges. Decades of investment in water resilience meant that customers were kept on supply and the company did not need to introduce hosepipe bans. This is due to its long-standing investment and proactive approach to water production planning, as one of the UK’s driest regions. Actions taken include encouraging customers to use water wisely, underpinned by the business’ industry-leading smart meter rollout, alongside reducing leakage and investing in infrastructure.

Alongside its investment programme, Anglian increased support for customers. Nearly 400,000 customers received tailored financial or practical support and c. £95 million was provided to help customers struggling with their bills. New measures included a Medical Discount for customers with higher essential water use – funded entirely by shareholders.

Looking ahead, Anglian Water will continue to invest at pace to secure water supplies, protect the environment and support growth across the region - including new reservoirs, expanded pipelines and long-term environmental improvements.
