Customers with payment difficulties

We are committed to working with customers who are experiencing difficulties in paying their water bills. Please contact us to discuss options that may be available to you.


We are committed to working with customers to ensure that a business account holder’s water supply is disconnected only as a measure of last resort; when all other methods of arrears repayment have been exhausted. We will only do so in the following instances

  • Failure to pay a bill relating to the supply of water/wastewater services,
  • Upon request of the account holder,
  • No registered occupant at the property has been established after attempts to determine occupancy /ownership,
  • Where the customer has entered into a payment plan and that customer fails to honour that plan.

For the avoidance of doubt a premise shall not be disconnected where this would involve another customer being disconnected.  As a minimum, Uisce Éireann will issue at least one direct notice in writing at least 5 working days in advance of carrying out a disconnection.  No disconnections will be carried out on a Friday, Saturday, Sunday, eve of a Public Holiday or a Public Holiday.

Settlement of arrears and reconnection

Where an account holder has had supply disconnected due to outstanding debt and subsequently reached a settlement with us through a payment plan or payment in full, the account holder shall be entitled to have normal supply restored. We are committed to ensuring the restoration of supply within two working days, subject to operational capacity.
