Our water licence
As an independent water company, we can serve sites in all areas run by an incumbent regional water company across England and Wales. We are regulated by Ofwat (The Water Services Regulation Authority) and adhere to the Codes of Practice and Guaranteed Standards for water companies. Our licence enables us to operate public water and sewerage networks under the Water Industry Act 1991. To find out more please see the useful documents section below.
Where we are appointed by a developer, a New Appointment Variation (NAV) is made by Ofwat. IWNL owns and operates the water and wastewater network in these areas, providing services to customers including supply of water, wastewater services, metering, and billing. IWNL has all the same duties and responsibilities as the previous statutory water company.
We calculate the water, drainage and sewerage charges using the amount recorded by your water meter, plus any standing charges. We calculate sewerage charges based on the assumption that a certain percentage of the water you consume will end up as waste.
We will aim to read your meter at least once a year. If we are unable to read your meter, your bill will be an estimation based on your average consumption. If you receive an estimated bill, and wish to let us know your current meter reading please login to your account.
Need help with high bills? We are here to help and may be able to find ways to support you. If you are worried about the cost of your bills please let us know as soon as possible.
