Non-household charges

Most business customers in our area of supply are metered, but a few will be on unmetered charges if it has not been practical to install a meter at their property. The charges cover up to four elements:

Water supply
This covers the costs of supplying water to the property. For metered customers the charges include:

  • A standing charge based on the size of the meter. This covers the cost of maintaining and eventually replacing the meter.
  • A volumetric charge, based on the amount of water supplied.

Used water
We only provide waste water services to parts of Powys. Other areas may be served by either Dwr Cymru/Welsh Water or United Utilities. The bill that you receive from Hafren Dyfrdwy will tell you who your waste water provider is.

Surface water drainage
This covers the cost of draining rainwater from the property. If no rainwater from the property drains to the public sewer then customers will not have to pay this charge. For metered customers this charge is usually based on the area of their premises which drains to the public sewer.

Trade effluent charges
If customers deposit more than just a domestic type of effluent into our sewers, we charge according to the strength of the effluent.

Unmetered charges
Where it has not been practical to install a meter at a non-household premises, charges will be based either on the rateable value of the property or on assessed volume. See the Scheme of Charges for more information.

Fixed charges
We also apply a fixed charge for each service provided to a premises (water supply, used water, surface water drainage and trade effluent). Fixed charges apply to both metered and unmetered sites.

These are mandatory consumption-based tariffs that apply to non-household premises using high volumes of water.

  • The intermediate user tariff applies to sites using between 10,000 and 49,999 cubic metres (m3) of water per annum.
  • The large user tariff applies to sites using 50,000 cubic metres (m3) of water or more per annum.

These annual tariffs apply from the first meter reading taken in April each year up until the final meter reading taken in April of the following year. Unlike our standard tariff, we operate peak and off-peak seasons, the latter of which offers a significantly discounted rate. There are additional fixed charges for customers on these tariffs.  

This tariff applies to premises that have an alternative source of water supply in addition to a mains water supply from Hafren Dyfrdwy.  

The premises must also have an Environment Agency license to extract a minimum of 10,000 cubic metres (m3) per annum from their alternative water source and have the capability to use the alternative source as a backup to the mains supply. Premises that are eligible for this tariff will be charged using capacity charges, volume charges and premium charges.

At the beginning of each year Hafren Dyfrdwy must be notified of the volume that the customer believes will be required from the mains supply. A charge will be calculated based on the capacity required. This will remain fixed throughout the year regardless of whether customers use any more or less than their initial notification.

We will then charge based on the actual volume of water consumed. Where this exceeds the notified volume in either the peak or the off-peak seasons, the excess volume will be subject to premium charges.
