Connection Charging Policy

The new policy provides a single clear, transparent and fair connection charging framework. The Irish Water Connection Charging Policy:

  • Sets out Standard Connection Charges for the majority of customers. Up until 1 April 2019, customers in different Local Authorities paid different charges for the same type of connection. These charges were not cost reflective and did not take into account the impact on the upstream network.
  • Provides a consistent, safe, and end-to-end connection service to customers nationally. At present different levels of connection works are performed depending on the Local Authority area, for example, in some cases the customer may be required to pay the cost of a Road Opening Licence (ROL) or to procure their own contractor to complete the physical connection

From the 1 April 2019 the Connection Charging Policy will take effect with the cost per single domestic unit for a standard connection being €2,272 for Water and €3,929 Wastewater (Connection Infrastructure up to 10 metres).

Self-lay surety (only applicable to domestic housing developments)

The self-lay connection agreement sets out the basis of the customer’s contractual agreement with Irish Water for the provision of services. The agreement provides for the vesting in Irish Water of water and wastewater services infrastructure installed by a customer, following quality assurance of the self-lay works and connection to the Irish Water network(s). It includes the provision of financial security to Irish Water (the Self-Lay Financial Security Arrangements) in certain circumstances.

As part of the Connection Charging Policy, a refundable financial security will be required per unit in a self-lay development. This will mitigate risk of asset defects and risk exposure where sub-standard work has been performed. This is applicable where the local infrastructure is provided by the customer and where a self-lay agreement is in place requiring the vesting of the infrastructure in Irish Water. The surety required is outlined below and will apply to all applications submitted on or after 1st April 2019. The surety will apply to each unit within an application.

Standard Residential Connection Apartment and Duplex
€1,125 per unit for water and waste water  €750 per unit for water and waste water
€562 per unit for one service €375 per unit for one service

In addition to the risk exposures outlined above for the water and wastewater infrastructure, there is an additional risk exposure for pump stations (this includes other stand-alone infrastructure facilities) in a development. The financial security relating to this is outlined below:

  • Up to 40% of the total cost of the pump station or stand alone infrastructure for the duration of the Defects Liability Period and/or
  • Up to 100% of the annual estimates cost of operation and maintenance of these facilities for the duration of the Defects Liability Period

This financial security will be required in addition to the full connection payment and signed counterpart in order for a connection to progress. Upon completion of the defects liability period the surety will be released in line with the Irish Water Financial Security Policy.

The Irish Water Self Lay Financial Security Arrangements sets out the acceptable forms of financial security.
