Water and Wastewater charges

There are two services which are paid for in water charges. The first is for the provision of clean water and the second is for the removal of wastewater. We don't physically provide the second service. Depending on where your business is, this is provided by Thames Water (whose charges we include in your bill), or Southern Water (who bill you direct).

We provide you with clean water. Information on the charges that will apply for this service from 1 April 2016 is available below. If you need more information, see our Non-Household Water Charges Scheme 2016-17 .

Our charges for last year are available in our Water Charges Scheme 2015-16.

Wholesale charges

Currently businesses that use at least 5 mega litres of water a year at a single premise can choose who supplies them with water. If you choose an alternative supplier your water will still be sourced, treated and distributed by us. We charge your supplier for this service. These arrangements are explained in our Network Access Code . Charges for this service are based on our wholesale charges. Our wholesale charges for 2016-17 are available in our Wholesale Water Charges Scheme 2016-17.

From April 2017 all eligible businesses, public sector, charitable and not-for-profit organisations in England will be able to choose their water supplier. We will continue to abstract, treat and transport your water from source to tap. Your retailer, the company that send you a bill, will pay us for this Wholesale service. The charges your retailer will pay from 1 April 2017 are described in our Wholesale Charges Scheme for 2017-18 and provided in the standard industry template here. The Company’s Board has confirmed its approval of these charges in its Assurance Statement.

These charges supersede the Indicative Wholesale Charges  for Businesses  that we published in September.

Having a water meter means you only pay for the water you use.  An additional standing charge covers related costs such as meter reading, maintenance and replacement.  Your sewerage charges (if you are connected to the sewerage network) are based on the reading taken from the same meter.

Our region is divided into three areas: Northern Area 1, Northern Area 2 and Southern Area. Your bill indicates which area you are in. Click the relevant link for the charges in your area.

If your premises does not have a water meter we refer to you as an 'unmeasured customer', and we calculate your bill by applying a 'rate per pound' to the Rateable Value (RV) of the property. RVs were set by the Government's Valuation Office prior to the introduction of Council Tax in 1990 and cannot now be changed.

Different charge rates exist for water services and for wastewater services. Each of these is expressed as 'pence in the pound' and vary depending on which part of our region the property is located. There is also an annual 'fixed charge'

There are two exceptions to this pricing structure:

  • some 'unmeasured customers' in Northern Area 1 (formerly the Sutton District Water Company) pay an annual commercial water licence fee;
  • some 'unmeasured' customers with a rateable value of less than £2,000 and who do not use water in the course of their business pay an assessed commercial charge.

There is also alternative  charges for unmeasured non-domestic supplies such as hydrants, bin stores and religious buildings.

Our region is divided into three areas: Northern Area 1, Northern Area 2 and Southern Area. Your bill indicates which area you are in. Click on the relevant link below to see the charges in your area.


This tariff is available to unmeasured business customers, whose premises have a rateable value of less than £2,000, and where water use is restricted to the domestic - "tea and toilet" -  requirements of the staff engaged on the premises.

It is not available where:

  • there is a domestic element within the premises
  • there is any use of water in the course of the business, or
  • the rateable value is more than £2,000.

The tariff consists of a standing charge based on the size of the supply plus an assessed volume charge based on the number of people in the premises.
