What are your charges for business customers?

There are three types of measured water and sewerage charges for businesses:


The standard measured tariff; this is where a measured supply of water is made available subject to our standard terms and conditions of metered water. The sewerage charges are usually calculated on the assumption that 95% of the water consumption recorded by the meter is discharged to the sewer.

Where it's not reasonably practicable to fit a meter, or it's unreasonably expensive to fit one, then we may charge on an assessed basis which is based on the band of water charge determined by the type of business and the assumption that 95% of the water is discharged to the sewer. On change of occupier the premises will remain on the assessed measured charge however the band may be reassessed based of the type of business undertaken by the new occupier.

Customers may choose our industrial tariff when a large volume of water is used at a single site and/or the discharge of sewage is 100ml or more per annum from a single site.

For traders who've been permitted to discharge trade effluent directly or indirectly to a public sewer, they'll be charged on our trade effluent tariff. This will either be on our standard tariff, or where the volume of effluent discharged from a single site is 100ml or more, then the industrial tariff may be better for you.

You must notify us in writing in advance and agree to pay by monthly direct debit. We'll agree terms and conditions with you in each case. Failure to comply with the terms and conditions agreed may result in the tariff being withdrawn, without notice.

You'll be charged based on the band chosen for a minimum period of 12 months. Each band applies to all consumption and discharge between 1 April and 31 March and comprises of:

  • A fixed charge for the year (which includes an annual standing charge for the first meter)
  • An additional standing charge for each additional meter based on the size of the meter
  • A volumetric charge.

The charge will normally start from the first day of the month in which the application is received and will continue in future years unless you request, in writing, in advance for a change of band.

If you think you might benefit from our industrial tariff, please complete our application form and send it to us at P.O. Box 690, Cardiff, CF23 5WL.
