The utility says the standardised charges were subject to widespread consultation and were well flagged in advance. However, farmers with fragmented holdings say they are putting them at a financial disadvantage.
"When the meters were installed by the County Council, we were told there would be just one charge. Now they're putting a cost of €43 on us for each connection, it’s just not on," he says. "It arises from the fragmentation of farms. It would be a west of Ireland problem, but Mayo would be more afflicted," Mr Walsh said.
The utility says it provided information to the around 190,000 customers impacted around the country last year.
