Your water bill covers much more than just the cost of the clean water you use and the waste water we take away. Behind the scenes here at Hafren Dyfrdwy we work hard 24 hours a day, 52 weeks a year to ensure that you receive a clean and reliable water supply. And to do this, we need to manage all the pipes and treatment works on a day to day basis as well as invest in them for the future.

Our average household bill for water in the former Dee Valley area in 2018-19 will be around £157 or just 43 pence per day.

For former Severn Trent customers receiving water and sewerage the average will be around £348 per year or just 95 pence per day. And we’re proud to say that this is the lowest combined bill across the whole of Great Britain and compares to an average bill of £395 for all other water companies.

Every year we update our charges. There are a number of other changes that impact bills. They include:

• Changes in the rate of inflation,
• Reductions in our costs as we become more efficient,
• Changes in the number of customers we serve (and how much water they use),
  
• Changes to make sure that we haven’t collected more revenue from customers’ bills than the limits set by our regulator.

And if you’re on a meter, the amount of water you use could increase or decrease your bill. Discover our helpful water saving tips and the range of devices we can provide to help you save water and save money.
