Information for customers living in Wales 

You may have recently received a letter from us to say that your water company is changing to Hafren Dyfrdwy. We hope the following information provides some further detail around the changes to your water services

In February last year, we welcomed Dee Valley Water (a water company based mainly in Wales) to the Severn Trent family. Since we’ve come together, we’ve been looking at ways to make sure that our customers living in Wales and in England get the absolute best from their water services, so we proposed some changes to our regulatory (geographical) boundaries.

 What does that mean for customers?

• From 1 July 2018, the boundaries of Severn Trent and Dee Valley Water will be aligned to the border between England and Wales

• Dee Valley Water will be changing its name to Hafren Dyfrdwy and will provide water services to our customers living in Wales: this will include current Severn Trent customers living in Powys and the surrounding areas

•  Severn Trent will continue to provide water and waste water services to customers in England and will now also include Dee Valley Water customers living in England.  

On a day to day basis, there is nothing different, the water you get from the tap will remain the same and you’ll still get the same great service, From July you'll be served by Hafren Dyfrdwy. 

We’re writing to our customers to let them know about these changes. There is nothing that customers need to do right now, just carry on enjoying the water as you normally do, you'll be contacted again in due course with all the details of your new service.  If you have any questions in the meantime, please contact us as you normally would do.

Hafren Dyfrdwy means Severn Dee and  reflects the two main rivers in the new region echoing our dual heritage. The use of Welsh as the primary language reflects that that this is a Welsh business operating in Wales.

There will be no difference in your bill or the prices you pay. Prices during the period 2015 to 2020 were agreed in 2014 with Ofwat, the economic regulator of the water industry in England and Wales.

All payment plans, arrangements and any schemes will remain the same.  

Your regular payments should stay the same, if there are any changes, we will always contact you in advance to discuss your options and make arrangements.  

The arrangements will remain the same. From July, Hafren Dyfrdwy will bill on behalf of your  waste water service provider.
