The first Irish Water bills are due to begin arriving through letterboxes from today.

The company has already warned that they are likely to contain errors and incorrect information.

They're urging those affected to contact them, and have hired more than 700 customer service staff to take calls on the company's helplines.

Customers have two weeks from the date their bill is issued to pay.

Head of Communications with Irish Water is Elizabeth Arnett:

A total of 1.7 million bills will be issued, including to those who are not customers, such as those on group water schemes. 

People with questions can call 1890-448-448, with lines open Monday to Friday 8am-8pm and Saturday 9am-5:30pm. Lines are closed on Sundays.

The utility says it will take eight weeks to issue all bills in the first cycle.
