Welsh Water Dŵr Cymru supplies water to most households in Wales, except for part of Central North Wales served by a different water company. Welsh Water Dwr Cymru was owned by Western Power Distribution (a US energy company) until 2001. Ownership of Welsh Water Dwr Cymru was then taken over by Glas Cymru, a non-profit company without shareholders which manages Welsh water assets and supply infrastructure.

Where does Welsh Water come from?The status of Welsh Water as a public or private water company does not have any bearing on whether its water comes from one source or another. Welsh Water Dŵr Cymru depends primarily on surface water sources such as reservoirs and rivers to provide water, drainage and wastewater to the Welsh households in its supply area.

Dwr Cymru Welsh Water Login

water payments

There are two Welsh Water login options as the water company transitions to a new online portal. This impacts all Welsh Water Dwr Cymru customers as their old login information will not be valid on the new account portal and everyone needs to register for the new service. It's also worth noting that the new Welsh Water login only gives you access to account information in English. However, there is a Welsh version in the works and it should be available shortly.

If you signed up to Welsh Water with the old My Bill login, you will still have access to your legacy account information for a while longer. However, that does not preclude you from needing to sign up for a new login with the new My Account online system. Since both systems seem to be distinct, it is likely you will be able to use the same email to get a new Welsh Water login.

Having a Welsh Water login cuts down on your paperwork since you can access your bill and account information at a glance from any computer or smartphone. The new Welsh Water My Account is designed to be easier to navigate and get a handle on your account balance quickly.

To register for a Welsh Water Dŵr Cymru login, you will need the following:

  1. Email address
  2. Welsh Water Dwr Cymru account number from your water bill
  3. Postcode
  4. Telephone number

Once you get a Welsh Water login, you will go paperless and there is no way to receive paper bills by post unless you deregister from the service. However, no one is stopping you from printing out your water bills downloaded from Welsh Water My Account.

Welsh Water Problems

To be aware of and solve Welsh Water problems, it is best to have an up to date Welsh Water login and to check the Welsh Water In My Area website. This website details and situates any current or upcoming outages, problems or planned work on a map of your local area. In this way, you can keep tabs on Welsh Water problems that could impact your household water supply or other issues that affect local traffic, for example.

Welsh Water Leaks

While you can report Welsh Water leaks outside your property by calling 0800 052 0130 at any time, water leaks occurring inside your property are your responsibility when it comes to getting them fixed.

While Welsh Water Dwr Cymru is responsible for the water mains up to and including the stop tap or water meter, Welsh Water will offer complimentary repair of the private supply pipe connecting the private property to the water mains, whenever necessary and possible. However, this is not a guarantee and the private supply pipe is still the responsibility of the property owner, even in the case of a shared private supply pipe.

Welsh Water Complaints

When it comes to Welsh Water complaints, your first step is to lodge a complaint by calling the relevant helpline directly, for example, 0800 052 0145 open Monday to Friday from 8am to 6pm for billing issues.

The second step for Welsh Water Complaints is to write a letter or email. Here are all the relevant Welsh Water Complaints addresses for the second written step to your complaint. You should pick the one that best fits your complaint.

Welsh Water Payment

There are several Welsh Water payment options to choose from, based on your convenience. Let's take a look at how Welsh Water Dŵr Cymru lets you pay your water bill.

Welsh Water Payment Options

Direct Debit

This is the most convenient way for many people since it's a "set it and forget it" way of paying for your water bill. You can get started by logging into your Welsh Water Dŵr Cymru account. Additionally, your direct debit payments are protected by the Direct Debit Guarantee.

Online Payment

With your debit or credit card in hand, you can call up 0800 028 5209 or go to the Welsh Water Dŵr Cymru website to pay your water bill at any time. Just make sure you also have your account number so you can put the Welsh Water payment through easily.

Bank Transfer

To make a Welsh Water payment through your bank, you will need to following details:

  1. Sort code: 522107
  2. Account number: 01500007

Make sure you include your full Welsh Water customer account number when requesting the bank transfer. If you are making a bank transfer from abroad, you will need different details, while the customer account number requirement remains so that your payment can be correctly identified.

  1. IBAN number: GB51 NWBK 5221 0701 5000 07
  2. BIC number: NWBK GB 2L

Payment Card

You can request a Welsh Water payment card that will work at post offices, local shops or petrol stations. Using this payment card, you will be able to pay your bill in instalments at any Paypoint location. There is no fee when using the Welsh Water payment card. Be aware that this isn't a debit card and can only be used to pay your Welsh Water bill.

Post Office or Bank

Besides the bank transfer and Welsh Water payment card options, you can also pay by filling out a Giro payment slip. This Welsh Water payment method replaces cheques in Post Offices since you can't pay by cheque there.

Sending a cheque

You can mail a cheque along with the giro payment slip that comes with your Welsh Water bill. The cheque payment must be sent to: Dŵr Cymru Welsh Water, P.O.BOX 690, Cardiff, CF3 5WL.

Before sending your cheque and giro slip, make sure to check the following:

  1. Payable to Dŵr Cymru Cyf.
  2. Customer reference on the back.

Welsh Water Moving House

moving boxes

Welsh Water moving home queries fall into three main categories:

  1. Change of address to another property supplied by Welsh Water
  2. Moving into an area supplied by Welsh Water for the first time
  3. Moving out of the Welsh Water supply area and needing to close your account.

Another important aspect of Welsh Water moving home queries is whether you have a meter or not because that will affect when you notify Welsh Water about moving home as an existing Welsh Water customer.

  1. If you don't have a water meter, you can let Welsh Water know you're moving home up to 14 days ahead of time
  2. If you have a water meter, you must let Welsh Water know you've moved home on your move day or afterwards.

If you are a new Welsh Water customer, you can only let the company know once you've moved in and not before. The same thing happens for those existing Welsh Water customers who are moving away from the supply area and need to close their Welsh Water account - Welsh Water moving home notification after the fact and not before.
