There were a total of 650 Irish Water customer contacts logged in 2015, a decrease of 19 per cent on the number of Irish Water contacts logged in 2014.

The majority of complaints in 2015 focused around billing and account issues, charges and metering problems, with some 56 per cent of complex water complaints focusing on meter issues.

Irish Water complaints made up 17 per cent of the overall contacts received by the CCT.
