New Appointments and Variations

New Appointments and Variations (NAVs or new appointees) allow companies to offer water, sewerage, or water and sewerage services to a specific geographic area instead of the existing incumbent company. As a result, developers and large business customers can choose their supplier for these services. 

New appointees have the same duties and responsibilities that apply to all existing appointees.

Further information is available on Ofwat's website.

High Demand

Help to save water where you can

We’re all enjoying the hot weather but with more of us at home we’re seeing big increases in water demand that may lead to low water pressure in some areas. Our key workers are working around the clock pumping extra water into the network but we’re asking our customers to help save water where they can. Together we can make a big difference. 

You can help by saving water where you can, on average each person uses 142 litres per day and there are some really easy ways to save.
