It has emerged this evening that households claiming the water conservation grant will have to go through a second registration process later this year.
The Government had said that those wishing to get the €100 euro grant would have to register with Irish water before June 30.
But it has been confirmed that to get the grant, a second registration with the Department of Social Protection will also be required in August, before payment begins in September.
A dedicated website and call centre will be established by the Department to assist people in matching their unique Irish Water identification number with their claim.
The cost of this new registration is estimated at 2-3% of the €130m set aside for the grant.
