Your bill

The average bill will go up by 6% a year for water and wastewater services.

Our bills will remain among the lowest in the country for water and wastewater services. For a detailed breakdown of our charges, go to our charges 2026/27.

Over the next five years, we’re investing £2.6 billion in the region to improve the local water and sewer network.

To support this investment, bills will go up alongside increased investment from shareholders.

This major investment will upgrade key infrastructure, including pipelines, treatment works and pumping stations, meaning cleaner rivers, fewer flooding incidents and a reliable and resilient water supply now and for generations to come.

Every penny of this increase is going directly into improving our region. We’re also committed to spending 60p of every pound with local suppliers to make sure this investment stays in our region to support jobs and our local economy.  

Work is already underway, with a number of projects in progress across the region, tackling everything from replacing aging water mains and upgrading sewer networks to improving treatment works.

These improvements are already reducing storm overflow spills, protecting rivers, and strengthening resilience for homes and businesses.

Some of these projects include:

• Middlesbrough - 23km of water mains are being replaced as part of a £5m investment in water quality and to protect supplies for 2,600 homes and businesses in the area.
• Belsay, Northumberland – a £1.7m project to upgrade 15km of water mains between Quarry Close Point and Boghall Junction began in November 2025. The work will improve water quality and reliability for customers.
• Browney, County Durham – a £10m scheme upgrading Browney Sewage Treatment Works to increase capacity, improve treatment processes and protect the River Browney. Work will complete in winter 2027.

Nearly 800 projects are planned across the region over the next four years and include:

• Chester le Street, County Durham - A £52m investment to protect the environment is expected to begin in 2027. This will involve work to reduce the frequency of spills from 12 storm overflows in the area.
• Ouseburn, Newcastle – a £6m investment will start towards the end of 2026 and will focus on reducing storm overflow discharges and upgrading local sewer infrastructure. These improvements will help protect water quality in the Ouseburn and surrounding communities.
• Berwick-upon-Tweed - A £175m project to replace outdated storm tanks, install innovative smart monitoring, and strengthen the sewer network, reducing storm overflow incidents and improving water quality. Work begins in Spring 2027.
• Darlington – planning is underway for £25.6m worth of upgrades at Stressholme Sewage Treatment Works, alongside a £13.5m package of measures to reduce spills from storm overflows, which will protect the River Tees.
