Why your bill is changing and how we’re here to help
We understand that any increase in your bill needs to be clear, fair, and explained. Here’s what’s happening.
Our biggest investment ever, and what it means for your bill
Over the next few years, we’re investing £266 million in improving your services. This includes renewing pipes, strengthening treatment works, and protecting local rivers. Last year saw a larger‑than-usual increase and any future changes will be more manageable.
Lowest bill in Wales
About this year’s change:
We still have the lowest combined average bill in Wales (£48 below that for for Dwr Cymru)and one of the lowest in England and Wales, this year our bill is still £4 below the National Average (national average bill is £639).
We’re investing more than ever to make sure our network is ready for the future. From growing communities to changing weather patterns, we want to protect the essentials you rely on, from the water in your tap to the rivers and green spaces we all enjoy.
Even with these improvements underway, we’re committed to keeping costs down and offering a wide range of support if you ever need a helping hand.
