Water charges for businesses

If water is being supplied, you must pay water charges as a commercial organisation or a non-domestic customer.

Non-domestic customers include:

• Businesses
• Mixed-use customers, who use water services for both business and domestic purposes
• Group water schemes

For example, the following must all pay for their water:

• Hospitals
• Health centres
• Schools
• Farms
• Sports clubs

Recent changes to non-domestic water charges

On 1 October 2024, new charges for non-domestic water users were introduced. These new charges apply until 30 September 2025.

Find out more about these new charges in 'How much will I be charged' below.

If your bill significantly increases because of these new charges, you may qualify to have your bill capped.

There are 2 types of commercial water charges accounts, metered and unmetered. The amount you are charged depends on:

• The type of account you have (metered or unmetered)
• The amount of water you use

New charges for non-domestic water customers were introduced on 1 October 2024.

If you are a non-domestic user and don't have a water meter

If your business does not have a water meter you have an unmetered account. This means you pay a flat-rate charge to Uisce Éireann for your water.

If your business has more than one unmetered connection, you pay a separate fixed charge for each one. Unmetered connections are grouped into 2 pricing categories:

1. Band 1 – For most connections.
2. Band 2 – For connections that had higher unmetered charges in the past.

Which tariff class (band) am I in?

Most customers will be charged the Band 1 rate.

However, if your unmetered water charges were higher than the cost of using 1,000 cubic meters per year on a water meter, you will pay the Band 2 rate. This applies to charges before October 2021 (or October 2022 for some public schemes).

If you are a non domestic user and have a water meter

If your business has a meter, you have a non-domestic metered water account. This means you have a water meter that monitors your commercial water usage.

Non-domestic metered accounts have:

• A standing charge
• A volumetric (variable) charge for water

Metered connections are grouped into 5 pricing categories (tariff classes).

Your tariff class is determined by the amount of water you use per year (annual quantity).

At the end of each billing year, Uisce Éireann will work out your annual quantity for each connection. This determines which tariff class your connection falls into for the next year.

How to get a domestic allowance

You can get a domestic allowance if your water supply is mixed use (used for both domestic and commercial use). The domestic allowance applies at a national rate of 213,000 litres per year.

Commercial premises (like farms or other rural businesses) that are members of group water schemes have to pay for the water they use to run their business. 

Mixed-use customers get a group water scheme domestic allowance, to cover their domestic water use. In most cases, a water meter monitors this usage.

If your business belongs to a directly billed public group water scheme:

• You get a domestic allowance of 213,000 litres
• You are charged a volumetric charge for water usage above the domestic allowance, if you are a mixed-use customer
• You are charged for water services directly, if you are the occupier of the business property
• You are charged a standing charge and any applicable tariff

If your business is a part of a bulk-meter public group water scheme Uisce Éireann does not bill you directly. Instead, charges are set by your group water scheme at their annual general meeting (AGM). Also:

• You get a domestic allowance of 160,000 litres
• You are charged for water above the domestic allowance and for any applicable tariff class
• You may be charged a standing charge, which is set by your group water scheme at their annual general meeting

In both cases, business owners may qualify for discounts if the water supply is not safe to drink or may get allowances if leaks occur.

All commercial premises must pay their water charges. You can pay your water charges bill in a number of ways.

If you have difficulty paying your bill, contact Uisce Éireann to discuss your options.

If you do not pay, Uisce Éireann can:

• Take you to the District Court to recover the charges from you or
• Disconnect or restrict your water supply.

However, this is rarely done because of the implications for health and safety.

If you are a business in a private group water scheme, you pay the group water scheme for the water you use.

If you have difficulty paying your bills, you might be able to get a hardship waiver. A hardship waiver means that your bill is waived (not payable) or reduced. This waiver may be available if you are in a group water scheme that:

• Bills its non-domestic members directly
• Operates as a co-operative (owned and run solely by its members)

The members and trustees of your group scheme decide when charges can be waived or reduced.

If you are in a private group scheme and you are finding it difficult to make your payments, you should discuss this with the trustees of the group.

If you have questions about paying charges, customer categorisation, or need help with your water services, contact Uisce Éireann or visit their website.
