Developer Charges 2021/22

Welcome to Hafren Dyfrdwy Developer Services. On this page you’ll find helpful information regarding our developer charges for making water and sewerage new connections to our network. 

Our 2021-2022 charges

We know how important charges are for our developer customers and every year we undertake a review where we strive to provide charges that are easy to understand and wherever possible remain stable year on year.  To aid simplicity we have one charging arrangement document for 2021-22 that applies to all customer across the Hafren Dyfrdwy region. We also publish our new connection charges before they become applicable on by 1 April each year to help customers plan ahead. 

You can find more information in our latest Charging Arrangement Document (PDF)

Throughout our Charging Arrangement Document the term “developer” refers to all of our customers who are building and developing properties. 

If you’d like to see our 2020-2021 charges (which are still in use until 31 March 2021) please use the links below:

Hafren Dyfrdwy sewer adoptions

Hafren Dyfrdwy is both a water and sewerage undertaker and we'll adopt sewer assets that are constructed in Powys and parts of Monmouthshire. These were previously adopted by Severn Trent.

Sewer assets constructed in North East Wales will continue to be adopted by United Utilities or Welsh Water, depending on where your development is located.
