Wessex Water is reporting strong service and operational improvements in a strong first half of the 2025–26 financial year, according to its latest interim results.

The water company says it is continuing to perform well against its targets, which includes maintaining high scores in Ofwat’s C-MeX table and on Trustpilot, retaining the Customer Service Excellence award, and holding the top spot in CCW’s annual complaint handling report.

At the same time, Wessex Water says it is expanding help for those in financial difficulty and increasing access to Priority Services Register, which already supports more than 150,000 customers with additional needs.

Highlighting its commitment to improving environmental performance, the utility recorded no serious pollution incidents last year, although minor incidents did rise. To address this, Wessex is investing in sewer network improvements with a goal of installing 10,000 more in-sewer monitors by 2030, with 2,300 already added this year.

Alongside this, the company is expanding its water recycling centres, relining hundreds of kilometres of sewers to extend their life, and launching a new rainwater management strategy to keep rain out of sewers in partnership with customers and stakeholders.

According to Wessex, it is leading the way in carbon-friendly, nature-based wastewater treatment solutions, such as wetlands and reedbeds, with a record 31 new projects approved for construction between 2025 and 2030.

The report also points out that its water resources remain under pressure following an extremely dry spring and summer, leaving reservoirs and aquifers below average as it heads into winter. This has also increased leakage – however, the firm has accelerated repairs and are trialling innovative detection methods, including satellite imagery.

Looking ahead to the rest of AMP8 (2025–30),Wessex refers to its ambitious plans, with a record £3.65 billion investment planned – over £2 billion more than AMP7.

The water company's AMP8 business plan referral to the Competition and Markets Authority (CMA) is nearing its final stages. In October, the CMA agreed a 5% increase to £622 in customer bills to compared to Ofwat’s decision to allow an increase to £594 at its Final Determination in December 2024.

Wessex Water had asked for £642 – a 8% increase compared to Ofwat’s decision. The CMA has since been consulting on its provisional decision, with the final outome due in 2026.

Financially, the first half of the year saw turnover rise by £78.7 million, from £332.5million to £411.2 million, while profits after tax increased from £19.6 million to £50.1 million.
